BIOS Screenshots for overclocking at 4300 MHz:

110927120259 110927120317 110927120332 110927120340 110927120346 110927120357 110927120415 110927120430 110927120444 110927120452

Please keep in mind that the voltages for your CPU might differ from this example. If your CPU core is not stable at these settings and you don’t exceed 90 °C core temperature, try to raise the CPU core voltage.

 

Important BIOS Settings explained:

CPU Strap

The CPU strap (or BCLK Strap) is an additional multiplier to increase the base clock. Stock is x1 but if you e.g. selext x1.25, the BCLK will have an eventual value of 125 MHz.

 

PLL Selection

LC PLL works best for low/stock clock BCLK of 100 MHz. LC PLL is and inductor capacitor based oscillator for low noise but only for a low range. If you overclock the BCLK, change to SB PLL or simply leave on auto.

 

Filter PLL

This is only needed for very high BCLK of over ~167 MHz. Just leave this setting on auto.

 

BCLK Frequency

The Base CLocK of your system. This frequency is tied to the PCIe clock and the DMI bus. High frequencies can cause your system to be unstable. Use the BCLK/CPU Strap for high BCLKs. Raising the BCLK will also raise the CPU core, ring and RAM frequency.

 

CPU Core Ratio

You can choose whether you want all cores to be clocked at the same level (Sync all cores) or clock them separately (per core). I recommend to sync all cores to get the maximum performance.

 

1-Core Ratio Limit

This setting will change the CPU multiplier of your system. If you run a BCLK of 100 MHz and select 37 here, your CPU will run at 3700 MHz core frequency.

 

Min. CPU Cache Ratio

This will set the minimum CPU cache/ring ratio. If you run a BCLK of 100 MHz and select 35 here, your CPU cache/ring will run at 3500 MHz. I recommend to use the same as Max. CPU Cache Ratio here.

 

Max. CPU Cache Ratio

This will set the maximum CPU cache/ring ratio. If you run a BCLK of 100 MHz and select 35 here, your CPU cache/ring will run at 3500 MHz. I recommend to use the same as Min. CPU Cache Ratio here.

 

Internal PLL Overvoltage

This can improve the overclock-ability of some CPUs. I recommend to set this to enabled.

 

BCLK Frequency : DRAM Frequency

This is an additional divider to achieve higher memory clocks on the RAM. I recommend to use 100 : 100 since 100 : 133 can be bugged on some systems.

 

DRAM Frequency

The DRAM Frequency is the result of the BCLK and an additional multiplier. E.g. 100 MHz BCLK and 18.66 multi will result in 1866 MHz RAM frequency. Higher than 2933 MHz usually doesn’t work. If you want to achieve higher memory frequencies, you have to use a different BCLK strap.

 

Xtreme Tweaking

This can improve the performance in some benchmarks such as 3DMark2001 and SuperPi. Disable for 24/7 systems.

 

CPU Level Up

Automated overclocking. I recommend to not use this feature.

 

EPU Power Saving Mode

Configures the system for power savings – leave this setting disabled for overclocking.

 

CPU Core Voltage

This is the core voltage of your CPU. Increase this voltage if you want to achieve higher core clocks. Usually more than 1,35 Volt is not recommended for daily use.

 

CPU Cache Voltage

This is the cache/ring voltage of your CPU. Increase this voltage if you want to achieve higher core clocks. Usually more than 1,15 Volt is not recommended for daily use.

 

CPU Graphics Voltage

The GPU Graphics Voltage is tied to the internal graphics processor (HD 4600 for 4770K). Only change this if you use the internal graphics processor and if you want to overclock it.

 

CPU System Agent Voltage

This voltage is important to run high memory clocks. Stock is 0.85 Volt and usually you don’t need more than 1.00 Volt for 24/7 systems.

 

CPU Digital I/O Voltage

This voltage also helps for memory overclocking. Stock voltage is about 1.0 Volt. More than 1.15 Volt is not recommended for daily use.

 

CPU Analog I/O Voltage

This voltage also helps for memory overclocking. Stock voltage is about 1.0 Volt. More than 1.15 Volt is not recommended for daily use.

 

SVID Support

Enables or disables the SVID bus between the controller and the processor. When pushing BCLK, the SVID Clock rises accordingly and thus disabling when overclocking is best.

 

Initial CPU Input Voltage

CPU Input Voltage during the power on self test (POST).

 

Eventual CPU Input Voltage

CPU Input Voltage after the power on self test (POST)

 

DRAM Voltage

The DRAM Voltage is the Voltage of your memory. Check the memory modules for the specified voltage. Most are between 1.35 and 1.5 Volt. The official limit according to Intel is 1.5 Volt, however 1.65 Volt modules are no problem at all according to my testing.

 

PCH Core Voltage

This is the chipset voltage and doesn’t have to be changed since it doesn’t help in any way.

 

PCH VLX Voltage

This voltage can help overclocking the BCLK. Lower for high BCLK and increase for low BCLK.

 

VTTDDR Voltage

This voltage always has to be 50% of the DRAM voltage. So if you use 1.5 DRAM Voltage, this one has to be at 0.75 Volt. Simply leave VTTDDR Voltage on auto because all boards apply the correct value automatically.

 

CPU Spread Spectrum

The spread spectrum reduces signal spikes. However it will leade to a worse overclocking so always disable this setting.

 

BCLK Recovery

If you adjust the BCLK in windows e.g. with TurboV Core and restart, the BCLK Recovery will reset the BCLK to the boot value fixed in the BIOS if enabled. If you ignore this, the same BCLK will be applied after a reset like you set in windows by software.

 

Maximus Tweak

Maximus Tweak 1 can help to increase the performance and Maximus Tweak 2 can help to increase the overclocking. I recommend to use 2.

 

Enhanced Intel SpeedStep Technology

Intel SpeedStep will downclock your CPU in idle to save energy. I recommend to disable this feature because you only save about 2-5 W, but it can cause your system to be unstable when overclocking.

 

Turbo Mode

Leave this setting enabled using ASUS motherboards. Otherwise you will not be able to increase your CPU multiplier.

 

CPU C-States

The C-States are another energy saving option which I recommend to disable for maximum overclocking.

    Hi Bauer, könntest Du mal ein OC mach für das Maximus VII Hero auf 4600 mit i74790k. Besten Dank und Gruß

    • der8auer

      Kann ich morgen machen. Ich mache es prinzipiell mal auf 4,5 GHz. Die genaue Kernspannung für deine CPU müssen wir dann getrennt betrachten.

  • k3im

    Tach Champion! Danke für den Guide. Hilft mir immens, da ich mich noch nie an ein Intel System gesetzt habe und hier nun wirklich alles anders ist als bei AMD :) Das einzige was ich irgendwie nicht finden kann ist die Einstellung für die LLC. Die würde ich natürlich am liebsten disablen. Gruß!

    Hey, hattest du nun ein Guide für das Asus Maximus Hero VII gemacht? Ich hätte gern evtl ein Link dazu. Ansonsten würde ich gerne wissen, ob man CPU-Cache Ratio auf Auto stehen lassen kann oder man es wirklich justieren muss..

    Servus Roman (Bauer), habe ne Frage und zwar benutze ich das Maximus Hero VII + i7 4790K, der CPU lief die ganze zeit auf einem festen Takt von 4500 und es war auch alles wunderbar aber vor kurzem habe ich mein Bios offen stehen lassen und mein sohn hat darin rumgeklickt und gemacht was 4 Jahrige eben so tun. Naja seit dem schaltet der Rechner unter Prime 95 und der einstellung aus deinem video (Custom, threads 8, min fft= 1344, max=1344, RunFFT in place) nach 10 min einfach aus und bootet neu. Ich weis einfach nicht wo der fehler liegt. Hab es mehrfach zurück gesetzt und genau so wie ich es damals eingestellt hatte wieder eingestellt aber …. ja scheise. Vieleicht vergesse ich ja etwas deswegen wäre es echt cool wenn du ein video zu der kompletten oc config für das Board und den CPU machen könntest oder mir die wichtigsten einstellungen einfach zukommen lässt.

    Ps. Dein ( Delid-Die-Mate ) ist sehr schlicht aber einfach Klasse, super Sache. Hab ihn kürzlich gekauft. Endlich ein humaner weg am schraubstock vorbei zu kommen.

    Würde mich echt über deine Hilfe freuen, das heist fals du zeit und lust hast.
    Mfg. Chicolo83
