Hello,

I am new to overclocking, but I did purchase the ASrock x299 OC Formula and a delidded 7900x. The recommended stable setting s to run all cores at 4.6GHz is:

1.225V Vcore

-3 AVX Offset

-5 AVX512 Offset

Like I said, i am new to this and have no clue how to apply these settings on the ASrock x299 OC Formula motherboard.

I've looked for Vcore but cant find it.

Also not sure where to set the -3 AVX Offset or the -5 AVX512 Offset.

There are some nae setting on this board it's a bit overwhelming. Need a pro to set me straight.

Thanks

Wow! You and me both wish that you were asking three simple questions.

That is all the information about over clocking that you received with your CPU? There's a thing or two missing. That's also very general information, with no details.

Some new settings in the UEFI/BIOS? Many of them are new to all of us, since the Skylake-X processors are unique in many ways. You have a sophisticated board for over clocking, and that can be a problem for those learning to OC. Add to that the complexity of your processor, and you have a steep learning curve.

Another problem is, I've never used an X299/ Skylake-X system, so I can only go by the board's manual and previous experience with the previous Intel HEDT platform, X99. BTW, did you download the complete manual for your board? It contains the layout of all the options currently provided by your board's UEFI:

http://asrock.pc.cdn.bitgravity.com/Manual/X299%20OC%20Formula.pdf

First, I assume you have switched to the Advanced Mode of the UEFI?

To start finding the options you listed, go to the OC Tweaker screen.

On that screen, you'll be using the CPU Configuration, Voltage Configuration, and FIVR Configuration screens to configure the three settings you asked about, and another that IMO is missing, more about that soon.

Going in the order of your list:

VCore: In the FIVR Configuration screen, find the CPU Vcore Voltage Mode. Is it set to Auto? Click on this option and set it to Override Mode. Press Enter, and you should see the VCore voltage setting appear. Set it to the suggested 1.225V. Below it should be the Vcore Voltage Additional Offset option, leave it on Auto. If it is not set to Auto, let us know. If you have other options such as Fixed, let us know please.

An example of missing details in the information from the CPU source is what VCore voltage mode is suggested? Could be Adaptive, Fixed, or Override, some of the typical options.

AVX Offset: In the CPU Configuration screen, find the AVX2 Negative Offset option. Terminology can vary between sources, but this should be the main AVX offset setting. Either enter -3 or press the '-' a few times to get -3.

AVX512 Offset: In the CPU Configuration screen, find the AVX3 Negative Offset option. In the same way, set this to -5.

The main thing that was not mentioned was the CPU Input Voltage. This is not the processor's VCore. Are you familiar with the Intel Haswell and Broadwell processors? Like your processor, they have some of the voltage regulation done on the processor itself rather than the mother board. When over clocking, the CPU Input Voltage may need to be increased. You should see the CPU Input Voltage shown on the H/W Monitoring screen, which in the past defaults to 1.8V. Since your VCore at 1.225V is not very high, you may not need to increase the CPU Input Voltage. That option is in the Voltage Configuration screen.

Another important option is CPU Load-Line Calibration. You may be adjusting both this and CPU Input Voltage is your OC to 4.6GHz proves to be unstable.

To help you learn, at the top of the OC Tweaker screen is the Load Optimized CPU OC Setting option. These are built in over clocking profiles that will populate various options in the UEFI for various over clocks. You should enable on one of two of them, and then go through the screens listed above and see what options have been changed, and to what values.

If you really have "no clue how to apply these settings", you could apply one of these OC profiles, and simply adjust the three settings you listed.
