If I don't have anything running but the 2 GPU clients, my cpu usage is a steady 2%.

You might want to diddle with priorities, to make sure your GPU client is running at a higher priority than your CPU clients. I'm no expert on this subject so that will be the extent of my advise.

Hot air rises. Makes sense to me. I'm just surprised at the degree at which the upper card seems to be heated by the lower card.

The positive-pressure case design should ensure that there is good airflow through and between the cards.

I fiddled around with overclocking in the beginning but I came to feel it wasn't worth the trouble, and the risk of trashing work.

Update: Confirming that the upper card is running hotter because of it's location. I swapped the cards and the temperatures remained constant, i.e. the upper card running several degrees warmer than the lower card. For the summer I have little choice but to turns the clocks down. I've turned the clo...

Good input. There is one slot separating the cards, but it does make sense that the lower card could be heating the upper one. OTOH, I didn't have this issue until recently. The upper card may be have run a wee bit warmer, but nothing like this. I may try taking the case apart and re-seating the sto...

I bought it for an 8800GT but that card did not offer PWM fan control so I didn't bother and replaced that card and a passively cooled 9600GT with a pair of GTS 250s. There...

GPU client beating the crap out of my graphics card

I have the clocks on one of my GeForce GTS 250 graphics cards turned down as low as the EVGA Precision tool will allow, and it's still running 81 degrees and the fan at 83%. I am using the just released drivers, the official Windows 7 drivers from NVidia. I'm seeing some strong PPD numbers, but don'...

I always have about 1 GB of memory free (out of 6).

I have picked up a second one. My points will take a hit for a couple of days.

I'll finish them comfortably before the deadline, which is 7 days.

Project 5102

I just picked up a 5103, worth a whopping 3340 points, but the first 1% took 53 minutes to complete. That makes it worth only 900 PPD and it wi...

It's definitely possible.

The 8600GT has just 32 shaders so it will be no folding monster, but it should be good for 1500 ppd or so.

I wonder if you could do anything with priorities? FAH should be running at a priority just above the idle process, but that would be worth verifying.

Consider the entire cost of the rig, not just the incremental cost of the graphics cards. I started with an 8800 GT, with the thought of buying a second one. It was soon retired because it was (A) noisy and (B) doesn't play well with other graphics cards.

I was gone over the weekend and my computer crashed late Saturday night and didn't fold all day Sunday.

I wish I could figure out why it does that. About once a week, sometimes twice, it crashes and reboots. I don't have Folding@Home set up to start automatically. I guess I need to do that, huh?

I like how quiet my graphics cards are at stock clocks, with the fans running at 50% or less. Except sometimes I get WUs that really drive my GPU temperatures up and then for a few hours they aren't so quiet. FAHwatch reports I've had one EUE on 37 work units. I wasn't overclocked at the time. [/img]

Are you running Windows 7 64-bit? The 185.20 drivers are now known to cause one card to run faster than the other in Vista 64 and Windows 7 64, so even if they're equal right now, once you get a new WU on one of the cards, it may pick up speed and run faster than the other. However, 13k PPD sounds ...
