What could cause system lock ups while Folding?

[Nate-X]

I had made it through 1 (wu is what I think it was called don't remember lol).. and went about 65% on the 2nd and the system locked up (didn't notice til this morning since I had left it running.) Could the fact that I've oc'd the processor and raised the fsb cause? Thanks.

*edit* Oh yeah I am using the purty graphicsl interface version 2.19

The first thing I woulds look at is your temps.

[dimmreaper]

Daniel is probably right. But if your temps look good, then you may need more core or memory voltage, or you may need a little less FSB.

[Nate-X]

Ya the temps are fine.. usually around 101.. 102 degrees fahrenheit.. The fsb is farely low at 144.. I'll check out the voltages though =/ is there any quick way to test out a system setup.. rather then 'waiting' for it to lock up in a particular application?

[dimmreaper]

BTW, folding at home and similar distributed computing applications stress the core voltage power supply on the motherboard for long durations. It is for this reason that I recommend gluing heatsinks on the MOSFETs and placing a small fan(10CFM is pleny) to blow in that general vicinity of the motherboard.

[Southern Man]

Daniel's right on the money on this. F@H uses 100% of your spare cycles so if nothing else was running it was using everything you had. It's a great tool to test your O/C for this reason. Watch your temps while folding and I bet it goes high. If you need a temp monitor program get mother board monitor from AOA files. It does a good job of not only showing current temps but also logs highs and lows on your temps, as well as your voltages. Good little tool, it is. You may need to back off your O/C a bit or look at your cooling situation and see if you can get more cool air to the HSF.

Nope, not really. Usually 3Dmark is a good stability testing application. I usually run three loops of Sandra memory benchmark, then run through 3Dmark, and finish up with a FAH work unit. If it does all that without a hitch, I call it stable . . .

[Nate-X]

That's the thing though.. I go through Sisoft Sandra and 3dmark like nothing (only time it crashed were when I oc'd my card too much) Does FAH Work Unit tax the system more then those?

[Nate-X]

Hehe just noticed the other responses as well..

Just installed a couple 80mm sunons in the front of the case blowing in cool air.. have an ax-7b (i think hehe) the new heatsink from thermalright.. w/ a sunon fan and a 120mm sunon blowing in from the side of the case in front of where the processor is.

I have another fan mounted above the power supply blowing hot air out..

I was thinking about breaking out muh greenlea and installing some additional fans in the side of the case or putting a blowhole at the top to get rid of some additional heat. I'll pay close attention tonight to the temps and see if that is what's posing a problem =/

Try Prime 95. The ultimate test.

[Nate-X]

Is that the program that has a disclaimer.. this program might cause damage to your system.. lol.. that frightens me

While 3Dmark200X mainly tests the graphical side of things, Folding@home stresses the CPU to its max... so 3Dmark may run well, with folding locking up - or vice versa. Try lowering speed a bit to see if that does the trick. My bet is that you won't need to lower it much.

Good luck - and welcome to the fold!

Here's a link to the FAQ for Prime 95, it does mention something, but nothing that's out of the ordinary for any DC project.

edit: like a moron, I forgot to add the link. Here it is:

If your CPU can survive a couple of hours of Prime 95, then it's pretty much stable. Then you have to go down the list to check other components. Memory should be next. The Sandra memory bandwidth thing looped about a dozen times should be enough.

[Nate-X]

Thanks for all the help guys.. I'll download prime 95, test the CPU then tweak the fsb if need be and hopefully it'll work just peachy after that.

[Nate-X]

Well, put the fsb back to 133.. back to cas 2.5.. and the processor back to default voltage.. whenever I run Sisoft Sandra and perform 12 memory burn in tests.. after it gets to the 10th test it logs my user out and I have to relog back into my admin account =/

Sounds like you might have bad memory. When my memory went it caused pretty bizarre behavior too. If you have 2 sticks, take one out and try the Sandra memory benchmark again.

[Nate-X]

I only have the one stick.. boy am I glad I've got new memory on the way My brother will have to deal with this in a week bwahahaaha.

Prime 95 & F@h @ the same time, bothe fighting for cycle's, mine did ok.
