under load? depends on your ambient temps.

I'm newbie so not sure what you meant with under load? tongue.gif I am in my ac'ed room - I am comparing the temp to when I run exactly the same load, and ILL Overvoltage AUTO, which shows temp to be about 35-40C b/c vcore is only around 1.3V (didn't try prime95 when overvoltage is disabled, but when it's auto, prime95 running, temp is about 50C)
thanks for any input! i really appreciate...i'd like to run this baby in a stable state and cpu being not hot... also b/c with ILL Overvoltage AUTO, my compt does not wake up from S3 either. i just need it to be able to run my simulation for 2 days w/o dead biggrin.gif

Under Load = Cpu running at 100% (prime95)

Im not sure how it affects the temps, that is certainly weird, it could be that it alters the LLC setting. You can easily find that out by checking what the vcore is under load when Overvoltage is on auto and disabled. More than likely what you are describing is that with with PLL overvoltage disabled the llc settings compensates the vdroop further which is quite interesting.


The purpose of PLL overvoltage is that it allows higher mulitpliers to boot. Generally it should be disabled for multi's less than 48x.

One thing that PLL overvoltage does is that it disrupts the sleep function, therefore you cannot use both.

thanks so much for helping. i think my LE board just does not let me change a lot of things for OC. i didn't know before buying it frown.gif but oh well,... i've disabled Internal PLL overvoltage, keep the offset into minus, and auto. it seems to run fine around 4.3ghz when prime 95 runs, temp is between 55-70C (when length of FFT is low, seems the temp is a lot higher, but 1792 and 1344 seem to run fine nand tem pis about 60-65)
you guys think that's fine/
thank you
