Using a file cc_config to limit the use of the GPU is possible that the Boinc manager stops any new WU. I had a same experience with Poem and GPUGRID...after a little my cache was empty and the Boinc manager didn`t get new WU! By removing the cc_config file the problem was solved :-)

Mistery solved. I am now in the second batch of my new rig and all four coprocesors are now running cuda tasks. This might be some kind of "testing" of the cards from the project side.

Zoltan;

I read with interest your problems with the 690 card.

I have a workstation that came with a Quadro 4000 and a Tesla.

I wanted two GTX 590 cards instead but was having problems with the "reverse airflow" causing the GPU closest to the front of the case to operate at least 20C higher than the one venting out the back of the case.

I just finished rigging a dual water cooling solution using a Koolance EXOS and two Danger Den water blocks. Both GTX 590 are now mildy OC'd and running at 53-57C.

I have never understood why Nvidia thought having the airflow going in two directions (front and back) was ever going to work properly in a cases with fans blowing directly into the exhaust of the front GPU (like my Dell Precision). To me water cooling is the only reasonable solution for the longevity of the card.

I'm glad you got yours working properly!

Maybe they never did? Reverse the front fans (and have some input somewhere) and the problem is gone.

Problem is on the Precision chassis (as with most, if not all, Dell tower chassis) the airflow goes in the front (usually assisted by one or more fans) and out the back.

Reversing the huge front fan in my chassis would affect more than just the GTX 590 cards, I have to consider the secondary Xeon processor as well. So reversing that fan was not a good option for me. So water cooling was the answer.

I know now that it's easier to build a "killer cruncher" by buying components and doing all the engineering yourself than it is to try and take an off the shelf workstation and adapt it to the task of devouring WUs.

Next time I'll go with something like the EVGA SR2 and whatever the current best-in-class GPUs are, etc.

Easier, better and less expensive...

My only GTX 690 (with the failed then changed cooling) has failed yesterday while it was crunching. There was no environmental hazard of any kind.

What´s the temperature you was running it mate? I don´t let it ever pass 75°C, and my 6 where ok for almost a year now.

The temperatures of the GTX 690 were 62°C and 65°C. Everything was OK. This host had a GTX 670 beside the GTX 690. The GTX 670 kept on crunching fine after the GTX 690 had failed. I didn't overclocked the GTX 690. It simply broke down in the middle of crunching. This host has an Enermax MaxRevo 1500W power supply, and an ASUS Rampage III Extreme motherboard.

what was the cause of the error?
If you can tell? Like was it temperature related or a NAN or something else.

It wasn't an error from what he wrote, the video card died. I had a GTX670 die 2 months ago for no reason (water cooled), it was a eVga video card with a 3 year warranty and I have it as a spare now after getting the replacement back.

Sometimes hardware just breaks. If there was any observable, even remotely possible reason in his case he probably would have mentioned it.

The workunits didn't fail, only the card. The GTX670 finished the two workunits which the GTX 690 could process only partially.

It seems that one of my 690´s on the 3x690 rig had a leaked vapor chamber. Luckly enough, I was able to catch the temperature increase in the exctly moment and underclock it. Just ordered a Accelero cooler to this unit.
Retvari, a question: i can´t figure is for sure from the pics, but once in place, this card/cooler will use 3 bays right?

Yes. It's HUGE in every direction :). It's 5 cm taller and 2 cm longer than the card itself.

Man, it seems a pain to assemble. When it was all ready, I figure that I didn´t have the little wrench to remove the original screws from the back of the 690. It´s a micro allen wrench? It´s so small that I can´t even see it right!

It takes awhile. However I've made my job easier by using nail polish (enamel) instead of the insulating tapes.

No, it's a Torx (TX5, if I can recall it correctly, but I will check it tomorrow for you)

They are. I have reading glasses for that purpose :)

LOL thanks mate. I will look for that wrench... I really need it to put my hands on the card again. In the meantime, its crunching at 915mhz, 0.975v, 64°C...

LOL thanks mate. I will look for that wrench...

It's a Torks for sure, the only question is its size. It could be a TX6, or a TX5. I've find my screwdriver set, and the separate scredriver I've bought for disassebling video cards (it's a TX6) but I didn't have time to check which one fits exacly in those screws. (I was busy selling one of my old MB+CPU, and buying a new one)
