I used AMD overdrive for monitoring temperatures on my OC-ed [email protected] my cooler is a Zahlman CNPS14X with two more ventilarors on the sides. And AMD overdrive reports temperatures over 67C. This didnt sound right to me. So i downloaded several temperature monitorin programs like HW/monitror, CPUID monitoring and Core temp. All of them report the same max temp of 55C only AMD Overdrive is giving me difrent readings. So i was wondering wich of them are right because i wouldnt want do melt my cpu.
Sorry for my bad English.
Over drive might be the core reading and the others the socket?
Nope, HWMonitor and CoreTemp should report the core. At 67 degrees the CPU should be pretty damned near to shut down if it hasn't already. If it still runs fine and HWMonitor and CoreTemp are reporting sub 60 then I suspect you are fine.
Thank you GreyStrix for reasuring me.
I should have asked one more thing actually, that maximum temperature you are reporting - was it under Prime95 or normal use? If it's Prime95 you are golden (as long as you don't get core failures under testing of at least a few hours). If it is under regular use, then I would consider re-seating the cooler and making sure your case has adequate air flow.
I did it but only one hour of testing on AMD overdrive stability test. I didnt like my cpu working so long under 52C.
Edit:
I tried Prime 95 but this program has some isues with FX8350 cpu-s Many poeple owning this cpu are reporting this on the net and me ofcourse.
I just did AIDA 64 stres testing for 30 minutes and the max temp was 52C
And finally i uninstaled AMD overdrive.
What kind of issues with Prime95?
I have an FX-6300 and I can Prime95 solid for 12 hours without issue. Essentially, my cpu is yours but with a disabled module (two cores).
With stress testing you generally need an absolute floor minimum of an hour (with Prime95 anyhow) and generally most people will say 12 or even 24 hours to expose whether there is instability.
The issue was that one core always failed in prime.
I know u have a 6300 that why i am so interested in your opinion. ;)
But i found the problem. I forgot that i have put my timings a litlle bit down from their ratet spec. So i returned them to normal and ran Prime for 1 hour. No issues. Maybe the max temp only it was something higher 58C.
I think i am ok now?
Seems better. An hour is the minimum though, if you can handle longer it would be better.
It would seem i lied. One core has failed but the test continued. And now when i tried it two cores fail in the first 30 seconds? But i did 12 hours of AIDA 64 stress testing all cores 100%?
That is strange... Well anyhow, what are your voltages etc.?
You may need a voltage bump, and that (sadly) means that if temperatures get out of hand you may need to roll back the overclock.
Having core failures in Prime95 is the gold standard that your overclock is not stable.
At the moment i am at a low 1.409v @4.6Ghz Playing BF3 for very long runs and having no problems? I tried it to 1.45 same effect with prime..... I tried stock cpu speeds same thing?
55c @ load is bloody good mate. must be a bloody cold room where your pc is.
could be that one of the sensors on the board are a little flaky.
in the bios what is the idle temp? compare that to the idle temps with your apps in windows.
My fx 8320 is at 4.5ghz @ 1.41 which is about as low of voltage i get possibly get it without cores shutting down under prime. 4.6ghz requires 1.42v in which my h80i starts hitting 60c within about 15 minutes into prime (too high for me as my FX does 24+ hour renders ). If you need 1.42v to get 4.6 stable and your getting temps under 65c in prime (you can be sure no other day-to-day softwares gonna push 65c) it will be fine.
What do u use for monitoring temperatures?
In bios the temps are 29/30C I have a frend with an ASROCk board and when he cheks his temperatures in bios (same chip) it reports 60C but when he is in the windows enviroment he is geting sub 20C.
I tried a quick run @4.5ghz @1.424V And prime was stable for several minutes but the temps reached 62C so i stoped the test (core temp is what i used for monitorin). But hell i finaly got it stable in prime for some time at least. Only the temps are ugly. Il try lovering the voltage for a notch and report back.
Edit1: Prime failed when lovering voltages. So il be puting the clock to 4.4 with a voltage of 1.4 and see what hapens.
Ive just got 4.5ghz stable on 1.40v with LLC on 75%(ultra high on asus boards). Temps were about 57c 4.5ghz is the wall for my 8320 anything higher starts requiring voltages that my h80i cant handle.
I set my volts to 1.4 in bios LLC on ultra high and while im runing prime cpuzid tells me that the votages jump to 1.44v. The last run that i did was at 4.53ghz and the temps creep over 60C. Im done with prime in gaming with these setings my temps wont go over 55C. I will be monitoring my temps closely while gaming. If they exeed 60C I will give up the overclocking and leave the speed at 4.2 factory voltage. :(
It really comes down to luck with OC unfortunately, some go well and others don't. For example my last rig used a Phenom II x2 555BE which are actually a quad core with two cores disabled. It isn't all that uncommon to be able to unlock the locked cores AND overclock on those, but my locked cores were totally unstable so I was stuck with a mildly overclocked dual core :/ I've had better luck with the FX-6300 but I haven't really pushed it that far yet.
I had better luck with my [email protected] and [email protected] i got more MGHZ out of them at lower temps then this FX cpu. I dont dare to go over 4.53Ghz whitout a water cooler.
