I tried lowering it to 1.36 as 1.4 is high but it didn't change it? I restarted it and it was still at 1.4 VCore.

This did add stability for me since it keeps VCore from dropping during stress testing. Worth to check it out
BTW have you tried stresstesting @ stock? Maybe your chip is kaputt and you should RMA

Yes, I had stress-tested it @ 3.7 Ghz (Motherboard Factory Default settings + XMP @ 1600Mhz) for 10+ hours in Prime95 with no problems on the original Motherboard, so I don't think it's the CPU.

So can someone please give me the final OK that it is safe to try these settings (e.g. no setting is too risky) to achieve a stable 4.625 Ghz:

Those settings would work for me. There is a setting for "Boot Vcore" or something that can help if there is problems with getting the rig booted.

Those settings look great if they're working. Although you can probably CPU fixed frequency at auto.

Hey is there any way how to downgrade my Bios? I tried ez-flash utility as always it isnt work (says that is not up to date version)
Bios flashback in the back doesnt work for me

Is there any different way how to do it?

My audio realtek doesnt work and I want to try if the newest asus bios has nothing to do with it

Just download the older bios, go into your bios during startup and choose to reflash with the old bios you have put on a flash drive.

My 4.3 GHz OC

79520151.png

3820 being locked I obviously cant ramp up the multiplier anymore. Problem is, I can't even POST with BLCK at anything other than 100MHz

Any ideas as to why this is?

at 4.3GHz im getting low temps and not a lot of voltage needed for stability.

at 125MHz BLCK, i've tried the multiplier at 37 and, Vcore up to 1.45V

Turbo mode on, power savers off. I've tinkered and played but simply cannot get a POST at 125MHz BLCK

Any Suggestions? biggrin.gif

turn off turbo mode
