FX-8150 - Error while folding, Prime95 errors on 4 cores. Anyone else?

[nanaki333]

BIOS is completely up to date. The board is listed on Asrock's website as being compatible with the 8150. Swapped memory, tried a different CPU in the board, nothing works. Folding gets sometimes gets to 7% before erroring, most of the time it won't make it beyond 2% though. It then downloads a brand new WU.

When I first started folding, I completed a couple of WUs, but then it started hard locking. It has hardlocked twice. Tried all the usual culprits (PSU, memory, CPU). So either Asrock has some issues with their BIOS still, my chip is a dud, or BD has some serious problems in general with folding. Stock clocks, stock HSF. Temps within spec.

I'm running Prime95 on it now and going to let it go for 24 hours (unless it errors before then). Also going to pick up a 6100 or an 8120 with another motherboard (different brand) and do some more testing to see if I can replicate the problem.

Wouldn't surprise me if the CPU was a dud. Considering that it has a 125W TDP rating and is slower than the PII in some cases means that AMD is having some serious troubles.

 

[TakeNoPrisoners]

RMA?

 

[nanaki333]

errors on 4 cores. wonder if you need a special prime95 for BD because of the way the cores are. can anyone else confirm if prime95 works on ALL "cores"?

My Llano had an error on core 2 recently. Called AMD and they suggested an RMA. Got the new CPU and all is perfect.

Wow this is really bad if defective AMD CPUs are this common. I've never had one personally, though I've gone through hundreds over the years, ditto Intel.

Wonder if it's a 32nm GF issue?

thanks for the heads up. guess i'll contact AMD. there's no way to RMA to the place i got it from. they're completely out of stock.

TLB all over again....

"This common"? We're talking about 2 duds here...

2 duds does not equal common.

Seriously, I have a llano laptop and it isn't a dud.

 

[jacktesterson]

Odd.

I have been using AMD CPU's since the K6/2 Genre and have never had one quit. (A good 20 AMD chips or so over the years)

I would RMA.

 

[jacktesterson]

to the OP..

Are you running stock clocks?

 

[Keysplayr]

Well, how common were Core2/Quad duds? Nehalem duds? I dunno.

Original Phenom had some duds right? I don't think Phenom II did.

 

[formulav8]

Out of the 1000's and even millions of cpu's produced there WILL be a dud that gets through. There is no sane 100% way of preventing a dud from making it past QC.

I've had s775 P4 dud before (I still have it in a drawer). No AMD duds that I can think of?

Questions nobody can answer, though I'm sure AMD has internal numbers for that. I doubt however readily share such information though. Perhaps I'm wrong on that though.

 

[nanaki333]

to the OP..

Are you running stock clocks?

yeah. stock clocks, stock heatsink, temps well within spec.

 

[Gigantopithecus]

Seen far more problems with boards than chips. I'd swap the board if possible before RMAing the CPU.

 

[jacktesterson]

I would definitely try another board first. If you can't, RMA it.

My MSI 990FX board I had (just sold it) seemed to be really flakey too. I couldn't get anywhere near the Overclock on it on my 1035T as I could on my old 880G board, which is now back in service. (I had planned to buy BD but not worth it). The Gigabyte 880G board is only a 4+1 Phase too... where the MSI was 10+1.


That being said, I'd try my best to try another board first. There seem to be quite a few issues with the new chipset not being quite up to part yet.

I think the dud rate for bulldozer, by nature, seems to be 100%, even when working

RMA the CPU, trust me. AMD will encourage it as they did with me. I didn't even have proof of purchase and I told them I bought it off an AT member and they still gave me an RMA. AMD's RMA process was a walk in the park and I got my new CPU back in a week.

I replaced my mobo and it still had the core 2 error and I constantly get 0x124 BSOD when cool and quiet was enabled.

My Llano would only error when Cstates and/or cool and quiet were enabled. If all power saving features were turned off, it would run like a top.

i have no qualms with AMD's RMA process. all computers for my company are built in-house and are all AMD (best bang for the buck. except mine of course is intel

out of 100s of AMD CPUs, i've only had 1 that was a tri-core that stopped POST'ing in 2 different mobos. took a bit longer to get back than a week, but it was pretty painless.

Some reviewers also reported problems with the 8150:

When I got my 2600K system pulled together it would not pass Prime95 at stock. I kept getting errors.

Stock everything.

My memory passed memtest+, ran it for 24hrs just to be dead-sure.

Then I ran HCI memtest, it said I had memory errors. So I downclocked my memory until HCI said there were no problems.

Then my rig started passing Prime95 no problem.

I RMA'ed the ram, no issues now with the replacement sticks.

So you might want to be wary of your ram, even if it passes memtest+, I can speak from experience that they can still be bad but pass memtest+ while making a stock rig fail Prime95.

FWIW

thanks. i'll give it a try. i tried memtest86+ and it passed fine as well. i pulled the 8150 out to get the serial and stuff for an rma, so i'll put an x4 840 back in to run the tests.

Usually core errors on an AMD is a sign of a bad CPU unfortunately. You can easily see the warnings stack up in event viewer.
