Great work there, I wouldn't have thought of the screen saver. Since all my systems are at home, I turned off the screen savers on all of them just to keep from losing the extra cycles, so I guess that explains why I haven't seen this. But nice job figuring out the problem.

Ugh, blasted screen savers. On my quad every time it kicked in my gpu fans would return to default run speeds (like 20%). Instant heat problem.

And they consume a lot of resources.

thanks, cordis. i've got them all engaged now, and with rivatuner running concurrently the problem hasn't reared its ugly head (yet...).

Hey, sorry to resurrect a thread, but now I seem to be having this problem under linux. I took a couple systems and swapped motherboards in them, so I basically wound up taking my system with a 295 and a 275 and moving them from my cosmos S case to my fortress f-02 case. And in the fortress case, they seem to be baking, temps go right into the high 80s for the 295 and stay there, and my ppd on the 295 gpu jobs drop in half. Not sure what I can do about it under ubuntu, today I'm trying it with the top panel of the fortress removed, maybe that will let more air flow out. I'll probably wind up having to move them back to the cosmos case. You know, I would not have predicted that the cosmos case kept the cards cooler than the fortress. But it sure is crappy to see the 295 running like a 260.

So I swapped the cards between the systems last night, and in the cosmos case the 295 is chugging along at full speed, no overheating. Bizarre. I really thought that the fortress ft02 would be better at cooling the graphics cards. I'm going to have to post something about this over in the case forum. Huh.

You can't make heads or tails concerning cases. Some are cooler with the sides on, some off. The direction the fans blow can change temps. Most of the time I have all my fans exhausting the case. In there's an intake it's in a place where airflow doesn't really happen like under the hard drives.

This thread isn't dead.

No problems on my GTX 260 in a while.

Changed one of my boxes to a Asus P5N-D (socket 775 with nvidia chipset, sli capable) and now have 2 9800GT EE cards with accelero coolers on them folding along with a Q9550 at stock. Nvidia drivers are 197.45.

Riva Tuner can't seem to force the second card (gpu 1) to stay at a constant performance level. The first card (gpu 0) will typically stay at the performance 3D clocks that I specify. I also specify it for the second card, but it will drop back into that really low performance mode but still fold away. I thought this stuff was behind me. (Get behind me, downclocking!) I've tried evga precision and it doesn't seem to act any differently, either. Anybody have any suggestions?

Hi KansaKilla, if you're only folding on the card and presumably 24/7 so don't care about the downclocked low power mode and just want performance for folding then maybe modify the BIOS so there are no "down clocks!"
I found it easy enough to mod GTX260 BIOS with Nibitor, NVFlash and a DOS bootable flash drive. (Flashing under Windows x64 is hit n miss)

hey seb,

do you have a hookup on a guide for bios editing?

also, off topic, are you involved in the radiologic sciences, by chance?

Hi KK, I don’t have a guide as such for BIOS editing.

Thanks, Seb! I'll look into this and post back to let you all know what's happening.
