I've had my hands on three 3820 and all did 5ghz at similar volts. On air I used a Noctua and while running prime maxed 82c with ambient somewhere around 23c. My personal 3820 does 5ghz at 1.45v, though truthfully I never really bothered to try and bin them, all hit the targets and I didn't feel the need to keep pushing down the volts.

If your H100 can keep temps reasonable go for it. Can a H100 keep up with or exceed the Noctua? This I know not. My personal 3820 maxes out at 72c btw under a full loop.

Not gonna lie, I'm a bit confused. I will try to set the multiplier to 43 as you said and leave everything else as it is. What's the worst that can happen?
I have the Asus Sabertooth board if that helps =/

Open CPUz and check your stock voltage. If you don't have it download it as it is free. Then up your multiplier and go into the OS and recheck. If it overvolted it then simply reboot and set the stock voltage into the BIOS manually. I would also raise the LLC 1-2 notches. That should be all you need to do. The CPU will still have power saving on. Or, even better, you could just input the voltage into the BIOS at the same time you raise the multi to 43x and you won't need to recheck the voltage.

I've got a sabertooth here with 3820. On that rig it's running 43x100 with offset enabled and set to -.060 = 1.23 ish. Iirc, LLC is set to High. You best read the ROG guide.

aight went into bios had a look around and set the multiplier to 43 and that is all I did. went in to the os started prime 95 and than had a look at things.

is the vcore voltage thingy too high? do I need to do something about that?

also I really appreciate you guys helping me wink.gif
post #989 of 6498
Yeah that voltage is too high for that minimal overclock. I would try lowering it to 1.25v (or less if possible).
post #990 of 6498
i cant get anything stable past 4.3, i think either my board sucks or my cpu sucks.

ive tried everything lol but as soon as i touch bclk or bclk straps it boots like crap or doesnt post etc
