Vishera Prime95 stable club - Page 2

post #11 of 14
Hey guys, I'm doing searches all over Google and every hardware site I can find, looking for info on FX-8350 owners.

Here's my issue. I just bought an 8350, installed on an Asus M5A99FX PRO. I've had the system up and running for about a week, and it seems totally stable for gaming. I actually have the multiplier at 20.5 so CPU clock is roughly 4.2, not a major OC... and as I said, system has been totally stable in all games so far. However... when I first put the build together, I tried running Prime95. While running prime, temperatures immediately skyrocketed, I think I saw 67C before I shut it down. There were no Prime errors, warning, or failures, but temps were ridiculous. Yes I am using the stock cooler, but I have read that other people ran Prime on the stock cooler and reported normal temps of 55-60C. Can anyone give me some insight as to why my temps, only in Prime, are so high? Is my CPU just defective and running hot?

what test did you run? If you run high FFTs that will take your power usage to its peak it can get things quite hot.

I am not surprised that a 125w CPU @ 4.2 is going to threshold temps on a stock cooler. How many volts are you pushing? 1.4+ I imagine.

my i5 gets to 100* at only 1.2v, but we also have different temp reporting (and smaller fab). 105* is the tx-max for Ivy Bridge but I dont like to go above 70*, also only OCCT heavy linepack or Prime High FFT runs cause it cross over 80*


point being get a better cooler, the 8350 needs one even at stock.




Now my main reason for posting here, glad to see some sensible gentlemen taking pride in their FX Prime stability and not running from it screaming "Prime is broken it doesnt like my Piledriver"

Reps coming to everyone posting here =) if I had stuck with AMD I would of surely joined this club.

I agree about the Prime statement for the most part. But what of the people who claim their piledriver fails at stock? I've been trying to figure this out myself, even though I don't have a piledriver lol

it comes from using an outdated version of Prime that doesnt address a bug found when using FX series chips.

Its something thats supposed to happen with Bulldozer and Piledriver
