i74770k cores temp discrepancy

post #1 of 6
Thread Starter 
Is it normal that I am seeing a discrepancy as below
Core#0 max 84
Core#1 max 88
Core#2 max 83
Core#3 max 80

This kind of differential is consistent across various tests with Core#1 always running much hotter than the rest and Core#3 being the coolest.

I'm using H100i with factory applied thermal compount, but i may have installed it slightly incorrectly. Or these are normal variations that come from minute differences in manufacturing? Thanks.

It's running at 4.4GHz (100x44) @1.19V, cache x39@1.15V (not sure if stable, in the process of testing right now).

bwt super unimpressed with the OC-ability of this chip, I was either unlucky or didn't install something properly.
I'm also going to improve the airflow in my case but at best that could shave 3-4 degrees i'd imagine...

not much discrepancy there tbh



if you was seeing 90 80 75 66, then i'd worry about it

ah got it, thanks! i'm just completely new to the world of OCing/monitoring so i wasn't sure if this falls in the norm or not

thanks for the confirmation, appreciate it!

i keep trying to inch down the Voltage, do you happen to know what a reasonable stable lower bound would be at 4.4GHz? I tried 1.2, 1.19, 1.18 so far Intel Burn Test completes with 10 runs fine, I'll keep going down until something happens I guess smile.gif

I always see ~10 degree difference between all cores on the 3 or 4 chips I've overclocked.

For my two cents, Haswell sucks for overclocking. My 3770k at 4.8 looks to faster than what I can get from haswell....comparing superPi and the gflop count.
