version 1.68 and shows me the vcore could see, my motherboard is msi power

but the version 1.68 OC cpu z shows the vid

HWiNFO64 in the VID 1.215 remains constant in this well or would have to get off at idle?

Cpu-Z 1.64 and latest HWmonitor display halved VCCIN (inputV) for Vcore, on my MB. I checked at 1.8, 1.85 and 2.0V and each time the vcore under cpu-z and hwmonitor showed half of that (0.902, 0.928 and 0.998V)

On haswell the vcore is no longer determined by the MB but the CPU itself. The board only controls the VID. So the Vcore reading must be implemented by the MB manufacturer. I assume all high-end ones do, but my 125€ one doesn't.
If your board does not provide Vcore info, it won’t matter what app you’re using. If it does but it’s under a different name, try to establish yourself which one it is or ask somebody with a board like yours.

ok, so using the proper avx x264 test, 4700mhz required the vcore to be 1.28v and I dropped vccin down to 1.94v. doing this allowed me to run x264 without bsod and I will do a continuous loop on x264 to see if its long term stable.

you know what, screw it. Its time for go big or go home status. Im looking for a 24/7 overclock that exceeds the community average. Currently at 4800mhz and 1.31v typing this. Ill post a successful x264 avx run.

Well the community average is 4.5GHz @ 1.275v. So....mission accomplished!!! thumb.gif

ahhh....I thought 4.6 was the average. Either way. Anyway looks like 4800mhz requires 1.36v. Im under water would that be safe? And I guess 4700mhz at 1.28v is better vs. 4800mhz at 1.36v

Alright nevermind. looks like I ended up with a pretty good chip, but, I will stay at 4700mhz at 1.28v and not risk killing this thing. 4800 needs at least 1.375v to run a loop of x264. Not worth the extra 100mhz. now to play with uncore.

Yeah that's scary! Nice and cool though, must be a custom loop. I'd bring it back down to x46 so you can lower your voltage.

Unless you are running a test for all of us... it would be interesting to see how long it lasts at that voltage.
