you think if i dont change the voltage and leave it on auto it will most likely start to bsod?

I only overclocked the uncore boost freq not the base. Its going to boost to 3.8 anyway is what I meant.

Couldn't find it there, but it's on the package itself as S-spec: SR147 is mine. Seems those 2 I listed are engineering samples or something. So.. anyone have anything newer than C0 SR147?

oh so you are basically saying that its better to start above 3.8x since thats the intel boost anyways?

imo yes. after my clocks were stable I turned the power saving stuff back on so the uncore can throttle down to 3.4 when the cpu clocks all the way down.

Prime95 with FFT set to 1792 and 90% memory usage seems to be the best stability test for me. My CPU has passed hours of AIDA, smallFFT, blend and BF4, but to pass 2-3h of 1792 I had to bump my voltage by 0.2V. Right now I am running x44 core/x42 uncore with 1.27V core/1.2V uncore

I can really recommend it, it finds instability really quickly and it isn't anywhere near small FFT hot levels. Just warm like AIDA.
post #9566 of 19539
core 42x 1.240v
uncore 34x 1.165v
LLC lvl 7
Initial voltage 1.170
Eventual Voltage 1.850
at 1333MHZ
using x264 HD 5.0 as stress test

should i set my ram to xmp now?



edit: forgot to post cpu-z

just tried to get 40x uncore at 1.18v and i stress tested it with x264 well i thought it was going good until i left it overnight and it crashed, computer was in a grey screen and couldnt do anything had to restart, probably have to up the uncore cache voltage.

40x definitely needs more than 1.18v, you should be good with 1.2v -1.25, depending on your particular CPU....thumb.gif

Kind of offtopic, but has anyone tested impact on games of balanced vs high performance power plan? Because balanced is like 30W less in idle, but I don't want to sacrifice any precious frames during gaming smile.gif

offtopic.gifwink.gif

Nope, I haven't....I set my power profile the way I wanted it and left it alone....biggrin.gif
