    Is there a chance to patch a bios for the z170 pro gaming mainboard ?

  • TIA


    You’ve got some great info here, thanks for sharing.

    Is there a bclk bios update for the Asus Z170-P D3?

  • Yazon2006

    Hello, der8auer! Great work to keep all bioses in one place! I have Asus Z170-P and now I’m gonna sell it because I’m really interested in overclocking. How do you think is there any chance that my current motherboard will receive possibility to overclock through bios update or not? It is very important for me. Thanks, and hope for your answer!

  • There is a new BIOS for the GA-Z170N-WIFI (rev. 1.0).
    With this BIOS you can oc non-k cpu´s.
    Tested with i3 6100T.

  • Max

    Any results? write pls who have stable OC

  • Raider

    So only the Asrock has an overclockable non-k ddr3 motherboards ?

  • Bob

    How about the “ga-z170n-gaming 5”? I saw a new beta bios on the GB site but no info/readme explaining non-k bclk overclocking. My Asrock z170 was rough with cold boot problems so I just ordered the GA-Z170N-Gaming 5 hoping they would have a bios out soon.

    • Bob

      Confirmed: Beta bios for the Gigabyte ga-z170N-Gaming 5 from Gigabyte’s website unlocks BCLK. I have a stable overclock on an i5-6500 @ 4320Mhz. I haven’t tried to push it higher yet. Given that the stock speed is 3200Mhz, this BCLK OC is extremely successful. Essentially, you can take the extra ~$100 you could have spent on the 6600k and spend it on other components. I bought the z170 chipset and a non-K processor with this in mind.

      • der8auer

        Great work! Thanks for your feedback 🙂

      • Jens

        What settings did you modify to overclock your CPU … ? I own a Gaming 7, tried both BIOSes but failed to overclock my 6700 non-K.

        • Bob

          I set CPU core voltage to 1.35v.
          I set memory voltage to 1.30v.
          I set bclk to 135.
          I set the cpu multiplier manually to 32. (135×32=4320)
          I turned off cpu boost
          I disabled onboard video.
          I set my memory multi under default (set according to your memory speed)

        • Bob

          Any luck? Remember to use CPU-Z to check your frequency in windows; system performance monitor only reports stock CPU frequency.

          • Riccardo

            Hey Bob
            I have i5 6400 on Gigabyte z170x gaming 3… But you don’t use custom bios, right?

          • said

            what is the name of the bios exactly? I’m on gigabytes website and there’s f1, f2, f3 and f4 so which one is it? if you dont know can you please send me a link to the bios download?

      • andrea del magno

        Great job. wich valor we have to change? i have in arrive a 6700 and gigabyte g7. TY

      • sb

        Which beta BIOS did you use off of the website? Also, did you use the stock 6500 cooler?

    • aatif

      I am looking at the MicroATX version of the Gaming 5 board (GA-Z170MX-Gaming 5). Does it use the same BIOS or do we know if it’s compatible with non-K OCing?

    I have Asus h170-pro gaming….any hope???

    • Yazon2006

      Dude, I have Asus Z170-P and I think that chance to receive bios update is low. With H170 chipset hope is is much lesser.

    • der8auer

      I will talk to someone from asus soon about this. Will try to get the full range of BIOS for all Z170 boards. Not sure if it will work tho.


    I have an msi z710a gaming pro and i was able to oc my 6400 to 4ghz stable but i think my 2133 generic kingston ram is holding me back to ocing even higher any tips? But im already happy with this 700 mhz oc. Also i can’t turn on xmp because of my crappy ram.

    • der8auer

      What memory speed do you use at the moment? You should be able to use lower memory multipliers such as:
      So e.g. if you lower to x13.33 multi you can run 160 BCLK and it will still match 2133 MHz on the memory. (160×13.33=2133)

  • qihei

    I have an MSI Z170 krait gaming, brush the MSI Z170A krait gaming Non-K OC BIOS, OC does not play role, pay attention to the two models are not the same, models the A
    Do you have a MSI Z170 KRAIT GAMING BIOS?

  • scott

    I’ve got the GA – Z170X-UD3 board and I see a bios for it which is awesome! I’ve ordered DDR4 2400 RAM for it.. and deciding on a processor. I’ve got a H60 Liquid cooler waiting to slap onto it.

    I was thinking an i5 6500. Not quite sure what overclocking to 4.3 or so does to my memory speeds though.. I don’t understand that bit yet. Thoughts before I push the button?

    • der8auer

      The memory clock is a result of BCLK x Multiplier. At stock with 2400 MHz memory you will have 100 MHZ BCLK x 24 Memory Multi = 2400 MHz Memory Clock.
      Overclocking the BCLK will also increase the memory clock. Increasing the BCLK to 130 MHz with 24 Memory multi would result in 3120 MHz. So you have to lower the memory multi. Here is what you can use:
      So e.g. if you lower to x16.0 multi you can run 150 BCLK and it will still match 2400 MHz on the memory. (150×16.0=2400)

  • valkyrino

    Any chance for Gigabyte B150 boards? B150M-D3H to be exact

  • TannerT

    Any chance MSI will release a bios for the H170 Gaming M3? If not am I a total idiot for considering to try and Flash the Z170 M3 bios? My 6500 is running at 30c under load with my H110, what a waste lol.

    • der8auer

      H boards can’t tune the BCLK unless they have an external clock generator. However, I think there is no H board on the market with an external clock generator :/ I don’t think it will be possible ón the M3 board.

    Installation MSI Z170 KRAIT GAMING Non-K OC BIOS, overclocking failure, BCLK101 can not start

    • der8auer

      I reported the issue to MSI already. Not sure what the solution for this problem is. Seems like several people experienced this problem on different boards.

      • Andy

        Hi der8auer, something news from MSI about bios for Krait mobo ? :/ Still the bios seems not non K, tested in 3 other krait board with different settings. Thank you

  • koffeeshop77

    Ok i have read just about every thing and im gonne pull the trigger soon.
    a) there are a lot of boards out there and you list: ASUS, ASrock, MSI, and Gigabyte.
    -Asus even listed on newegg that the Bclk can be risen, they don’t mention anything about a special bios update, so does Asus have an office version out there where BCLK can be MODed for the 6400,6500 usw…
    -my point is will there ever be a version where temp will be able to be read properly or is that just a wast of time?
    b)ASRock has a site where they list OC sky “unofficially” where they list that only certain models are “affected” by the false temp readings. mainly the lower pro 4 series.. and ITX. link below
    Link — >
    Leading me to believe that the other sieries outside of that ” list ” may actaully ” be able to read Temps, i could reallly care less about the GPU inside the chip being diabled, i have a 970, im not using it any way but i like to push limits and no readouts really make wonder where the border of water cooling ocing would be cause from what i have read 4500-4560 there is like a line in the sand that no one can cross without use of LN2, is it possible to go to 5gz on water? if yes can you use any board or is one board ” better” than the next from wht everyone talks about : word of mouth,phrasing; every board can go to 400bckl and so just get the 6400. (27×400=10800= ludacris i know) but then woulndt the be a better chance to spend 20$ more = better binned start with 32×156 and then reach 5000 at least or is there the just a barrier??
    c) yes theres more.. RAM why cant i get 3000 DDR4 ram why would it be better to stick with lower RAM like 2600 or 2666? if i bought 3000 down clocked and then got really tight timings @ 2666 than buying 2666 and just stick with the timings i have? does the XMP profile work at any more once flached or is that out the window too? is there a posibillity to OC it then set the RAM to 3000 or will it really just crash you system of you arnt on a certin “portionaly” frequecy to co-inside with the cpu, like 1333,2666,3999, cuase i like ocing my PC not my wallet. and is there any batter RAM i heard samsung how do i know which is samsung dosnet really say it on the package when i buy it,
    -a recommended Parts list would be nice before people end up with a board and CPU thinking well lets just flash it, – you got to think about poeple coming from ddr3 that dont quite so get it like ME , or stupide stuff where one site like THGuide recomnds low power Ram, where if we really want to oc a non-k other RAM might be nessarry.
    e) i had a Z77 MSI mpower and was disatifide and it broke on me on top of that, so i dont like MSI has there OC ablities imporved since then and there cooling of there “power convertes” where still crap any anybody esle any word on this?
    -i current have a Gigabyte and hate the software and options it came with, in a sence it has everything under the sun and works, but losses performance ttrying to manage all of it, also z87, so i really want to change preferbly to ASUS or ASrock as they seem to be pretty good up comers but on ASrock there are not just a little bit but alot of bad reviwes on newegg, im not sure in people only sign in to complain but alot of boards sound promising but whe 7 outta ten people say the usb3.1c dont work it really forms a pattern.
    -will evga board ever realease a bios?
    -and over best board recomended would be nice if some one could put up a community pol to vote on.
    -i really want to know if i can get a z170-a and be happy and get 4500 out of it or do i NEED the Rog Gene? cause it make a difference if half the stuff on the fancy board dosent work any way BUT OCing is a must!!! and its like a difference of getting everything now, or getting it next week, if ya feel me?
    final question ! is there a water cooler that reads Temps likefron the CPU/water the corsair H110igt/80gt or does it just read the temps from the mobo? and look fancy doing it ?

    • der8auer

      A lot of questions 😀 Will try to answer what I can.

      – All ASUS BIOS are non officia. I’m pretty sure they will keep it that way to avoid trouble with Intel.
      – I think they are still working on the temperature readout problem but not sure if they can fix it.
      – Only boards with external clock generator can go above 200 BCLK. So cheap boards will usually limit between 170 and 200 MHz. So in case you want to push really high you have to get a more expensive board ~ 160€+
      – Non-K CPUs seem to have trouble with higher memory clock and overclocking at the same time. Not sure why. But it also depends on the mainboard. Some boards can handle OC and 4000 MHz on the memory. But to be safe I recommend ~2600 MHz on the memory which seem to work in any case. Getting better memory just to lower the timings is probably not worth the money.
      – MSI has decent product quality. The only thing I don’t like is their limited support for loadline calibration on several boards. It’s pretty important and all other vendors support it. But apart from that – decent products.
      – I would not hope for EVGA
      – There are too many different boards out there and too many different needs from the user to give any good general recommendation
      – No you don’t need the RoG Gene. The Z170-A can handle 4500 MHz without any problems.
      – No clue about such a watercooler.

      • koffeeshop77

        thank you very much for taking the time to answer all my question, even i got tired typing them at the end, i bought a
        – Ex CRYORIG A40 Hybrid Liquid Cooler 240mm Radiator with additional Airflow Fan ,and the
        – ASUS Impact VIII with some
        – 16 gig tridentz 15- 3000 DDR4 (2×8) and
        i guess ill just see how that goes , dont get anything free so my credit card is clearing from newegg and itll ship once all falls in place, im alittle worried about how much wattage im going to use as got a crap cosair PSU and thinking of a 650NOVA before i start so im not set up to fail from the getgo, i think ill just do some testing first and find out how it is with out oc and then with. post scores later.
        either way i think the Impackt is the best of both worlds as ill prolly down size later to a caller sized case, seems to be where every thing is heading seeing as all those stupide steam machine are coming out atleast i can say i built mine. holla at ya later keep up the good work bruh/.
        thanks again!

        So cheap boards will usually limit between 170 and 200 MHz.

        does the cheap boards mean the board without external clock generator?

    I’ve been reading up on this and from what I can gather the following CPU features will be disabled with a BCLK overclock:

    – Integrated Graphics
    – Turbo Boost Frequencies
    – C-States
    – AVX

    Is that a complete list? And does that apply to all boards / manufacturers? Out of that list only the C-States give me cause for concern. I wouldn’t want to lose the dynamic frequency scaling or standby functionality… how does that work in practice? Can a non-k overclocked CPU still go into Standby or clock down when idle?

    Thanks in advance!

    if you’re having black screen when booting try removing everything in your usb ports except your keyboard and mouse also try downgrading (if you have an nvidia card ) to 358.91 this did the trick for me.

  • Hi,
    I tried 2.23 beta bios on ASRock page for Z170M Pro4S (which is not listed here)

    But after successful flash thru Instant Flash from USB drive, when it comes to 100 % and said “Computer will be restarted in few seconds”. After restart it won’t start. It beepes three error codes. One for bad CPU, next for bad RAM and last one for bad CMOS. :-/ They will send me new BIOS chip from ASRock.

  • lampaq


    I planing upgrade my pc too, before thinking about like most all people 6600k , but if non k cpus looks like very good oc like old times 🙂 , so now for what need look attention.
    CPU 6500 or 6600 ? or no matter which.
    Motherboard thinking Asus Z170 A /PRO, or gigabyte gaming 5/7 (7 most of it design 🙂 or didnt waste money for gaming 7 ? and if yes which mobo than ~160-180 USD will be perfectly.
    About Rams what I need to know ? Need to buy with higher frequency like 2600,2800 or enaught 2400.

    Thank you

      go for the cheapest CPU. 6400, 6500 and 6600 will all reach about the same clock in the end. So the 6400 is the best option. All of them should do about 4.4 GHz.

      • lampaq

        Ok I got IT,but how about mobo and memory ? Seems with MSI are more trouble with flashing Bios when i read all threads about non k oc here. Memory if I understund corectly need with higher frequency like 2666 or more .

  • ShiverinEskimo

    I happened to order the i5-6500 and MSI Gaming 5 before this method was highlighted. Trying to overclock now, got the BIOS updated correct, setting everything as above having cleared CMOS and it just will not take. It’s as if the settings aren’t even being saved.

    When I leave the CPU untouched I can clock the RAM to 2666Mhz and the voltage to 1.325 (temps perfectly fine) but as soon as I touch the CPU multipliers or BCLK the mobo seems to just ignore everything. I’ve tried leaving the multipliers untouched and just upping the BCLK but I get nowhere – stuck at the stock 3200Mhz even though when I re-load the BIOS the settings are all as I’ve left them – overclocked.

    Can’t help feeling I’m missing something but I’m tearing my hair out.

    • ShiverinEskimo

      Issue sorted by using M5 firmware E7977IMS.16T as quoted on this site. I had installed E7984IMS.16T to mimic the screenshots. Downloaded E7984IMS.16T from another source that claimed it was compatible with the M5. Turns out it isn’t fully compatible.

      Running at 4.5Ghz smooth now.

        • Andy

          Hardy, try to flash over MSI HQ USB tool flash . You need flash your mobo direct over this method . After that, if you change the base clock from 100 to whatever, pc wont boot because THIS bios version is completely wrong and no one int this world who can succesfuly overclocked the Krait . 🙁 … still waiting for something new

    • Yazon2006

      I’m very disappointed in Asus. I thought that Asus are so good as ASRock (they are both belongs to same Pegatron Corporation). But they are incredible different. ASRock made BIOSes for all motherboards and represented it on official site. Asus maybe afraid of confrontation with Intel. Whatever Asus sucks!

      • Andre

    • Yazon2006

      I doubt that this motherboards has same BIOS. Of course you can try to flash this BIOS to your motherboard but I think that your with 99% chance your motherboard will say that it’s incompatible BIOS version and 1% change that you motherboard will bricked. But I have experience in flashing my BIOS chip in nearest service center. It costs 2,5 dollar in my country. You can try to download this BIOS in such way but it’s unbelievable risky to flash incompatible version of BIOS.

  • ocUser

    I have ASUS Z170M-Plus motherboard. I was able to OC to 4480 MHz (BCLK 140) stable with 1.29 vcore. But when I set BCLK to 145, it doesn’t go to 4640 MHz, and is actually lower than 4480 Mhz. Anyone know why? I tried to set BCLK to 170 but never can go past 4550 MHZ. It this the max then?

    • ocUser

      Forgot to mention, this is for the i5-6500. When I set BCLK in motherboard to 145, it doesn’t say 4640 Mhz for the speed in BIOS, but rather lower speed than BCLK 140. When going higher BCLK, same thing, it can never go past 4550 or so MHZ even if I go up to BCLK 170. The speed in BIOS never gets past 4600 mhz.

    • David

      Mine sometimes does that just restart your pc and it should correct itself what sort of Temps are you getting in hwinfo for the cpu package? I’m getting a max of 72 but normally sits at between 65-66 at a claimed 1.375v at 140 blk which seems the voltage is quite a way off as my cooler is barly warm to the touch under prime95 load.

      • ocUser

        When using HWinfo, it will read temps with BCLK OC? I thought temps will read 100 c automatically. I did see the CPU temp in my ASUS 170M-PLUS in bios. But once I boot in windows, the temp monitors reads 100 c.

        So if I set BCLK to 145 it should be 4640 MHz once I restart? That’s great to know. Will try that.

        I think my i5-6500 I got may be able to handle 4.6 ghz since I was able to boot up with 142 BCLK @ 4544 ghz using 1.33 vcore.

        I am using corsair h100i gtx cooling.

    • ray

      Same thing happened with my ASUS Z170I Pro Gaming board. I also own a GIGABYTE Z170N-WIFI board so I can confirm my i5-6400 can run 4.5GHz (167*27) in Windows with an adequate voltage applied. But this ASUS board never even reads more than around 4.5GHz in BIOS as you mentioned. I think it’s just the ASUS BIOS thing.

  • Randy

    Is there going to be a bios update for Gigabyte GA-z170MX-G5?

  • Hi der8auer

    Any update on MSI Z170i Gaming Pro AC? Since there is a wide variety of ATX boards with the non-K overclocking capability and near none with mITX – are they lacking due to a missing external multiplier or is there another reason behind this?

    I genuinely hope for a reply,
    Thanks in advance

    • Bump

      Additionally as a Question:

      Does the BIOS read the CPU temps correctly, eventhough applications in Windows do not? As in, will BIOS provide adequate cooling by it self, ramping the PWN fans up, or does it not register any longer?

      Sincerely Rama

    I have my i3 6100 running @ 121.8 bLCK which gives me an OC of 4.5Ghz on the core and the cache.

    I am unable to get vccsa volts on my board (Z170N Gaming 5 ITX), which i need to clock my ram.

    My ram is currently running 3600 16-16-16-36-2T but bluescreens in Windows.

    I have this same kit running on my Asus Gene and 6700K system @ 3866 12-12-12-28-1T, but need vccio and vccsa, but with the Z170N i can only set the vccio. Is that a limit of the itx board, or limit of clocking the i3?

    Any chance for Gigabyte GA-Z170M-HERO BIOS?

  • Cipiripi

    Hello everyone. So I was looking for cheapest motherboard to buy that will allow me “non K OC” in my country it was this motherboard:
    GA-Z170M-D3H DDR3

    On your website it says its supported:

    My question is, can I overclock it with DDR3 1.5volts 1600mhz RAM? And should I buy i5 6400 or i5-6500 CPU? I know der8auer here wrote that you should get i5-6400 because its same chip and it will overclock same anyways. But Intel is saying that each chip has its own category and “quality” like silicon lottery. So on paper i5-6500 should be better overclocker than i5-6400?

    Please someone who knows let me know if I can use my old ddr3 1.5volts ram memory and if this motherboard is good, it has dual bios and all functionalities but I cannot find any review on English language on youtube or anything. And its 30$ cheaper in my country than any other motherboards out there, and i’m on really tight budget! *HALP* 🙁

    • der8auer

      Hey 🙂 The Board linked on my page is not the DDR3 version. So you have to be careful buying the correct board 🙂
      You can get the i5-6400. It will overclock the same like the i5-6500. There is no difference but 6400 is cheaper.

      • Cipiripi

        Thank you for info, I bought completely another motherboard, based on reviews and price range in my country (Serbia)

        I bought “Z170M Mortar”

        And processor i5-6400.
        It arrived today and I was happy to see everything is working great on stock. Then after couple of hours of testing to see if everything is stable, I decided to play little bit with overclocking.

        I downloaded your bios listed above:
        And installed via M-Flash file”E7972IMS.A42″ Which you get after you extract file “”

        I am not sure what is another file “” for. As it didn’t even see it at all via M-Flash.
        After my bios update completed and PC restarted, I entered Bios again to see it is indeed updated bios.

        Now my problem is next:
        I tried to overclock CPU by setting VCORE to 1.300 and pushed bus to 130, just to see if it will work. What happened next kinda shocked me, it didn’t save my clocks at all! In bios it says 2.7Ghz and in windows too, in fact I went from 519 Cinebenchr15 score to 430~

        I don’t know why it doesn’t accept overclocking?
        I also disabled C-state, and put RAM mhz to be little below 2100Mhz.
        I have no clue whats wrong, I assume it has to do something with that another file on bios update, that wasn’t even detected, but I have no clue really.

        I am not new at overclocking, I overclocked my g3258 before this processor which I have been using. And there it never came to situation that it wouldn’t accept my clocks at all.

        Hopefully someone with more knowledge than me can help me in my situation :/

        • Cipiripi

          I also put mode to Expert / NOC, but still no help. It won’t overclock even a single MHZ!

          • Cipiripi

            I downloaded older bios from your site and tried 1.325vcore and 4000mhz overclock, ram 2400 and my pc wont post at all now, monitor dont turn on… I tried resetting cmos by unplugging from wall for 30min and removing cmos battery and hold power button for 30seconds too.. After I put back everything after 30min my pc still not posting help im writing this from phone now i dont have pc anymore :'((

          • der8auer

            If cmos reset doesnt work, remove the CPU from the socket and put it back in after a minute. This will also trigger a BIOS reset.

        • Cipiripi

          I tried to put ram into another slot, to unplug all cables from motherboard and to put them back in, to put off gpu and to try it on integrated processor gpu, to put gpu in another pci slot… To reset jump on motherboard, while CMOS was inside, to reset jumper on motherboard while cmos was out…
          Only thing I can try is to remove processor and to put it back on :/ if that doesn’t work something died. I think its motherboard, one thing i’ve noticed is that my front lights are not lighting UP but i can hear my hard drive doing a spinning….

          I only put 1,325 vcore voltage and it killed motherboard (?) i think this shouldn’t kill it, i hope it didn’t kill processor too or all pc…. :/ I saw people stable clock on this vcore… I will try removing processor and will post back what happened, hope it will fix it. If not i’m calling tomorrow place where i bought motherboard from, this is for RMA, basically i didn’t do nothing bad! I know oc is forbidden, but what can I do :d I am within the rules, its not that I put insane voltage or anything! ofc, I will not tell them i did any overclcoking or bios update at all, i will just say that i turn on my pc today it worked, and after turnining it on again couple of hours later it wont post up.. :/ dang it. And I was confused why it wouldn’t overclock at all…. It was probably motherboard fault this whole time I think (?) and i’ve noticed when I had prime testing cpu temperature was like 69 after 1 min on stock speeds, something really fishing going on here. I think I just got bad motherboard or bad processor (?)

          • Cipiripi

            it doesn’t work even after cpu out for 15 minutes and then back in… same black screen and no lights on in front panel, all coolers are spinning and even motherboard LED lights are on though. Bleh. I’m not sure if CPU or Motherboard died….

          • Cipiripi

            I will send motherboard for RMA, and I asked my money back. Now I spend yesterday whole day reading about motherboards and what would be best one for me that actually works.

            I found myself between:

            I like this one because it has button where it puts clocks on processor on beyond stock, so your system can always boot, even if overclock goes wrong.

            This one supports AMD CrossFire and NVIDIA SLI. And is also quite often bought by people. I saw on skylake overclocking it achieved 5,000Ghz on i7-6700K and holds #1 place.

            Didn’t see non K overclocked processors with either of them.
            So what would be best buy here? Asus cost 7$ more.

  • :) smily

    for now which mainboard is the best for bclk overclocking? (in stablitly, performance, etc…)
    and which board has the longest support of bios with bclk overclock ability? (just give me a est. thingy or your opinion)

    as you know asrock recently block bclk overclock in the latest bios (h170 hyper, z170 pro4,extreme, etc…..)
    so asrock isn’t be a good choice?

    i saw msi’s latest bios update in april didn’t block bclk overclock yet.
    so than msi is the best choice for now?

    but by my exprience asus(except chip boards)and gigabyte has better quality than msi and asrock…(but msi’s vga is pertty nice tho)

    could you recomend the best mother boards vender for me?
    msi cuz of latest bios with bclk over clocking?
    or asrock cuz it still advertise their bclk overclocking function even latest bios dosen’t support it anymore?
    or asus and gigabyte cuz of good build quality than others?

    p.s. Is there h170 mother boards with bclk overclock like asrock h170 pro4/hyper, h170 performance/hyper?
    p.s.2 i can’t receive registration confirm mail 🙁

    • der8auer

      From my sources only MSI will keep the non-K BIOS up to date. So from my point of view I can only recommend MSI 🙂

      I’m not sure if there is any specific model from MSI but I think they should all get the same support from MSI.
      From what I know, ASRock, Gigabyte and ASUS will not update the non-K BIOS for now.

    Hey everyone,

    so I recently upgraded to a Z170A Krait Gaming 3x from MSI and was able to achive a stable OC of 4.3 GHz at 1.225 Volt. Not too crazy, but I don’t have the best air cooler, so I didn’t want to take it any further for now.

    There is one issue that I would like to address though: While Windows boots fine and apparently does not care about the higher BCLK, Linux does care. And it does so in a very unpleasant way: I am not able to boot any Linux distro from USB, HDD or DVD, including Ubuntu, Fedora and Mint. All of them halt during boot while initializing ACPI switches (I think, I’ll try to get a screenshot up later) or at this stage:

    The only distribution that has booted successfully for me is Debian 8, which installs fine. Problem is that I do not want Debian for various reasons. Looking at Google, it looks like I’m not the only one with this issue either:

    My question is: Has anyone run a Linux Distro other than Debian 8 with a BLCK overclock? If so, how? Any comments would be highly appreciated 🙂
