post #7291 of 67229
Hi all,

Looking for some help. I am trying to get a stable overclock on my 8350, I have no problems going to 4.8 on OCCT or AIDA64, but on Prime it just needs insane vcore to be stable.

I lowered to 4.7 and am stable at 1.4375 in AIDA, and a.1.46 in OCCT for hours on end, Prime though needs 1.5

Which should I trust? I can encode, play and never seem to have issues running 1.4375, but Prime immediately fails at this, additionally at 1.46 (the half way house) also everything is fine, i'm just trying to decide which I should trust?

Thanks,
Chris.

Guys, which temps reading software should I believe when OCing??..
Running at 4,5 at the moment, but when running OCCT or IBT, CoreTemp shows me different readings than OCCT itself or AIDA64 in the cores..
They're all different among them..
It can be as much as 10°C, sometimes are equal in 2 of 3..
For example, when running OCCT, its own chart shows me that the cores are between the 60s (60.2, 60.4).. But CoreTemp shows me they're at 65-66°C, and AIDA at 62.. rolleyes.gif
By the way, I'm getting temp pikes when running IBT or OCCT as high as 67-68°C.. But then it drops down to 58-60°C.. Any of you have suffered this during your tests??..

Best regards.. smile.gif

From my past experience, if i am not prime stable, i am not stable in games like bf3.

You really dont need to be prime stable. Though if you are OCD about it then go with the voltage you need for prime stable.

Otherwise just go with your initial 1.4375

I have an issue though. I got everything installed and running, and the first thing I did was Prime95 it to check my stability and load temps. It's currently still at stock speeds and all BIOS settings are default. Within 1 minute, core 6 got a "Fatal Error: Rounding was 0.5, expected less than 0.4", and about 30 seconds after that core 8 got "Illegal Sumout" frown.gif I let the test run for another few minutes and the other 6 cores stayed stable for the rest of the 5 minute run.

Here's what I'm getting from HWMonitor:
CPU VCore: 0.912v - 1.432v
CPU Temps: 34c - 60c (stock cooler)

CPU-Z shows me running at around 4.1 GHz fairly consistently. It doesn't seem to drop below that, but it fluctuates (probably turbo boost) up to around 4115 or so, haven't seen it go higher.

Here's my setup:
FX-8350, stock fan, stock settings
ASRock 970DE3/U3S3 (770 chipset, SB700 south bridge), BIOS version 1.6 (current version, I flashed it immediately)
G.Skill Ripjaws DDr3 1066 CL7, 8GB (2x4 GB) dual channel, stock everything on that too

Any ideas why I can't even keep it stable for 2 minutes with everything stock? Did I get a chip with bad cores? Thanks for any tips!

That is some really low speed ram for the vishera platform, I read a post about prime failing on certain cores because the ram wasn't able to "keep up" with the demands of 8 cores. I have no idea as to the validity of that claim but I would suspect that if it were true, your system would exhibit that behavior .
I have been able to add stability by increasing the voltage to the cpu/nb, have you tried bumping that up a bit?
Also , heat is your biggest enemy, make sure you have adequate airflow over the critical components on the motherboard.

Ran 20 ITB run at 5.0, will do more tonight cause i have to go work, sadly.

I still think i got a power hungry chip

You got a pretty decent chip there actually.1.536 for passing avx IBT is very good

Though the results -1 etc etc point to it not being stable at that voltage. Im amazed it passed

Hello Guys!

I have recently completed my first PC build; here are my specs.. http://pcpartpicker.com/p/xkko

I have the FX-8350 (with Corsair H60) and the Gigabyte GA-990XA-UD3 ATX AM3+ Motherboard.

I am looking to overclock my processor, but I have no idea how..

All help is appreciated!

Thanks,

Rohan
