What makes you say that?
My RAM is very stable at 2080. Is it that it stresses the memory controller too much?
Do you have a link to the info?
Thanks.

Having some fun building myself an optimized Gentoo distribution with my new FX ^^
That thing rips through everything!



Running at ~4.6GHz, CPU/NB locked at 1.1875v and CPU at ~1.440v
FSB: 250
CPU Multi... EEh. I don't remember. Will update when I reboot. Once on windows, I will post a validation link. This is not a club OC entry, only for your information.

Ambient temp at idle or under load ?

At 1.56V my chip would probably go to 75C with Prime95 ... It wouldn't be long before BSOD.

I have to ask - where did you guys purchase your chip ?

He's playing with Phase, Chilled, or DICE at that point, don;t try comparing to your own cooling. tongue.gif

I just bought an FX-8350 to replace my Phenom II X6 1090t. I cannot get my FX to run period in this setup. Not even at stock settings. It will lockup in games, crash during Prime95 blend testing, and the computer will just randomly restart.
My 1090t will run at 3.9ghz stable all day. As soon as I took out the FX chip and put the 1090t back in, all my issues went away. This is the only thing I am changing is the cpu.
Any clue as to what may be going on? Also, my bios, Core Temp, and HW monitor report a 12 degree difference over AMD Overdrive. Overdrive is higher by 12 degrees. Which one is correct?

I have the same mobo except it's rev 1.1 . Same F9 BIOS.
Same CPU.
Same CPU cooler, NH-D14 .
My case is different, HAF-XM, slightly smaller than yours.

Prime95 runs fine at stock 21 hours.

How many sticks of RAM do you have ? Do you have the proper timings ?

Are you running the memory at higher clock than you were with the Phenom by any chance ?

Trying booting Memtest and make sure the RAM is good first with the settings you have.

I know you said you just changed the CPU but you have to eliminate all possible causes.
If it fails at stock then you likely have a hardware issue. Could be the CPU, but I would look at the RAM too.

If memtest fails with all your sticks, try fixing RAM settings, and if that still fails, try with just one stick.

Not stable insofar as Prime95 won't pass Blend, Intel burn Test fails as well.

Sorry, but if you have 2 tests failing, you have something wrong with your OC.
Are both of these stable for you at stock ?

Actually, no bug has been confirmed so far for Vishera on prime95.

Use the Intel Burn testrun it 20 times at high and if it passes It is ok.

No way. I can run IBT 20 passes at 5 GHz but it's certainly not stable.
Prime95 will BSOD the box instantly, and a BSOD is not a Prime95 bug, it is an OC problem.

Id like to see a screenshot of u running 5ghz man with 20 ibt tests.
This is what you said yesterday or day before


I looked at your entire component list, looks pretty good to me. That Asus motherboard with the dual PS2 is nice, I'm jealous, my Gigabyte 990FXA-UD3 only has a single one. Really messes up with the KVM. Had to buy PS/2 - USB adapters for the mouse, and not all worked with KVM ...
Unfortunately many FX-8350 do run hot. FYI mine peaks at 45C after 21 hours of Prime 95 on stock settings/voltages, using Noctua NH-D14. Not sure if that's useful info. If I OC to just 4.3,, it will jump to 55C.
When I OC at 4.66 it peaked at 63C for 10 hours yesterday
Actually tried to run it again for longer at 4.66 and it peaked at 67C before I went to bed . And then today when I looked it had rebooted, got a BSOD. Sigh. so not stable at 4.66 . And today it won't even last 5 minutes with the same settings I had that worked. I saved the BIOS profile... Very weird.

So if you are peaking 67c at 4.66 theres no way in hell you are going to run 20 ibt runs @ 5ghz so please screenshot your proof of a ibt 20 run pls!! tongue.gif

I am running Gentoo too. Blender is more than twice as fast as the official windows version from blender.org. Takes me about 2 minutes to render my demo scene in Windows and about 40 to 50 seconds in Gentoo. FX loves gentoo.

I don't think he needs to. I passed a Cinebench R11.5 run at 5.18ghz at about 1.52v. It should be more than possible to at least get a validation out of it if it's a good chip on liquid.
