Default Sounds like a PSU issue to me...

mmm Very interesting.

My main rig has started doing something odd.

If I fire up folding on my 285 and 260 , about five minits later , it sounds like one of my HDD's is dropping out.....It makes a click noise , spins down , then spins back up again......this process continues every 20-30 seconds or so....

All the harddrives seem to work fine.I dont know which of the six I have is doing it.

It goes away as soon as I shutoff folding.

This sounds to me like the PSU might be getting low volts on the 12v line....(hw mon reads 11.49v at full load)

Any other thoughts ?

HW mond is very inaccurate for Measuring Voltages Braineater.

Are you sure you don't have a squealing Card?

Folding fried the thermal sensor on my hx1000 and left the 140mm fan spinning at 100 percent. 300 dollar PSU died before the return policy via the store ran out. PSU was broken in 4 days. Folding kills hardware.

Oh I have a squealing card too.....

This is very definitely a hardrive spinning down.I think It's one of my raptors ....funny thing is they both work....

....and one instance of folding alone doesnt cause it......both the 285 and 260 have to be folding to cause it.

I realize HW mon is innaccurate ....it is essentially showing me a .25 volt drop when both cards are folding.

-------

I am not able to physically get at my rig the way it's setup right now.I'll have to dissassemble it and move it into this room , i'll be able to tell what HDD is doing it then.

How Exactally did a PSU Doing what its supposed to be doing anyways Die from Folding?


@ BrainEater - Maybe the HDD's onboard controller is failing and Keeps slowing it down. Maybe Run one of those HDD Benchmarks on it and another known good drive before tearing it all apart?

Soul, all i know is the thermal sensor stopped working, was ruined, and failed to operate as intended causing the 140mm fan to spin 100 percent regardless of computer load. The only thing 100% loading the cpu/gpu during that 3 or 4 days was folding. Now... this is a known issue with these power supplies and folding is a known culprit. Sorry I love folding as much as the next guy but killing 300 dollar power supplies doesn't sit well with me.

Back to brain please it's his thread.

What PSU is this? Have you tried running other 3D stress tests like Furmark or 3DMark to see if GPU load is actually the cause of the problem? To be honest, it doesn't really sound like a PSU issue to me, but anything is possible.

Sorry, but you're completely off base. There is no way that your system can pull anywhere remotely near the amount of power it would take to risk frying a component of a 1000W PSU, unless it was defective in the first place. You're blaming folding for something that was simply caused by a faulty piece of hardware.

hmm....

It appears it's fixed itself.

I took the rig down, took it outside and cleaned it out with compressed n2......

Doesnt do it anymore .I've had it going full bore for 2 days now , it's fine.

I can only guess it was a loose wire or something....

Sigh... enough with the boys club attitude please. As far as I'm concerned a 140mm fan spinning at 2000 rpm; or whatever the max speed is, which creates more noise than I'm willing to deal with, is classified as screwed up PSU in my books. So in my humble opinion I am not off base and nothing other than folding would have caused the thermal sensor to stop functioning correctly. Should I just assume that it was faulty hardware and resume folding only to risk ruining another 300 dollar PSU? Folding can and will take a GPU to 100 percent and 80+ c if you choose not to control the fan settings on the vid card. That's not the way I roll... 80C+ vid card 24/7 is unacceptable to me and my apologies if you think it's stupid but that's my choice. The GPU was 500 dollars new... so I should risk possibly ruining 800 dollars worth of hardware for folding? Laff. I have a hard time believing a 300 dollar PSU brand new out of the box is defective or faulty but I don't deny that it isn't possible... Until folding cleans up their coding I won't sacrifice perfectly good hardware and a monster monthly power bill... I refuse to entertain the notion.

Hell you can have the folding tag back if you want it... i don't care.


On topic... glad it's workin properly again Rosco.
