Hi all,
I have an R4G and trying to do an offset overclock. See settings at the bottom of the post...
Everything seems really unstable. In manual mode I reach 4.2ghz (x42 multiplier) stable at around 1.32v it works from 1.31v but does a fatal error in p95 after an hour. I was excited by that in the beginning.
I turned it to offset mode it reported 1.32v first and then it reported 1.156 to 2.1 when I boot ( I am a bit confused by that but lets keep moving.)
I started with an offset of - 0.005 LLC Medium - cpu 120% . It had a crash on idle on load it was 1.36v which was OK. I raised the offset to reach 0.045 and that made it 1.376 on load and 0.845 on idle ( it was marginal ) it stayed stayed on idle for quite a while but it didn't work well. I raised the LLC to medium and tried to reduce the offset. I found that the load offset is too high and the idle offset too low .
I have a serious problem when things get stable at 1.38v x42 only. I know that the machine can work at 1.32v which is a bit strange why it adds so much more voltage and reduces so much more. IS there a way to make sure that the idle voltage stays above 0.85v?
By the way if I put the offset to Auto it works at 1.32 stable at idle and it does lower the voltage at 1.296v on load! Why is that ? This is not what it supposed to do ! Needless to say that it reports Fatal errors at p95 after 5 minutes.
Is there any way to increase the idle voltage without reaching 1.4v on load ? IS my 3960x crap? i have a few 3930Ks that are a piece of cake to overclock. Meaning they are stable in a much broader range of voltages. Another machine i have with ASus p9x79 pro it does 0.83v idle to 1.336 on load rock solid.
