Offset voltage help

post #1 of 10
Thread Starter 
Ok, after some more reading on these forums I decided to scrap my overclock with manual voltage and go for an offset approach.

I am Load stable but crash with STOP 101 at idle randomly. I think my voltage is dropping too low at idle and I don't know how to fix that.

Under load at 4.8GHz I'm getting 1.376 to 1.392 core voltage, I'm very happy with that. At idle I have seen it drop to .95V, and randomly it will BSOD (twice so far).

I have PLL Overvoltage On, offset is + .25

My question, what on earth is it + .25 of? is that a percentage? Is that Volts over some specific number? I have no idea what I'm controlling with offset and it is very confusing to me. My question is, is there a correlation to what I set in the BIOS and what I can expect for min/max voltage?

PLL Overvoltage is enabled, LLC Ultra High, VRM 350, Phase Control Extreme, Duty Control T. Probe, Offset + .25, PLL Voltage 1.6

+0.25 offset sounds like a lot of voltage...

this is what i did:
  • offset +0.060V
  • LLC extreme
  • phase control extreme
  • 110% current limit
  • VRM 420
  • PLL and everything else Auto

I think it will depend on your mobo. The .25 is .25 volts added to a either a)stock VID or b) a pre-set estimated stock voltage on the motherboard. So if you start with 1.25v a .25v offset will give you 1.5v before vdroop.

Stupid fat fingers... I meant +.025V

I'll give your settings a shot those settings a shot. At least now I understand a little better what I'm controlling.

you mean .025 or .25 ..??
if you BSOD under idle or light load,change LLC to medium and bump up your offset
phase/duty extreme
for 4.8 you don't need LLC extreme
EDIT; for 4.8 you probably looking @ +.08/medium LLC this would give you around 1.38v manual

after reading this i made some changes: higher offset +0.070 but lower LLC (from extreme to ultra high) and now it is 3-5c lower, rep+

nice flops,if you bsod under ultra,try to bump cpu capability 120%~130%

Hello to everybody. I've also got a question regarding the offset voltage.
Im at 4.7ghz now and using offset +0.12 (so should be 1.36) and my voltage vary quite much under load. For example if i use Prime Blend CPUz shows 1.36-1.385, the voltage is not constant. Then if i take LinPack it will show 1.352-1.36v, as for OCCT (medium) the voltage will be 1.36.-1.37. Can anybody please explain why there is such difference in voltage and its behaviour is not constant? Thank's
P.S btw i have LLC regular (0%),cpu current capability 120%, phase/duty extreme,VRM 350 Maybe there are some other settings i should change to get more stable voltage?

im no expert but all that looks perfectly stable to me.

voltages will never be absolutely fixed as load varies, things are not perfect, VRM freq is not infinite, etc..

Ok many thank's for your oppinion. But when i use manual voltage it doesn't vary that much but im not sure.
May i also ask about PCH voltage, do i have to touch it and what does it actually give in overclock? I have it on auto now.
