Si es así, la tarjeta de 8400 es muy lenta. Puede probar y optimizar mediante la instalación de los controladores más recientes (185,85) y el uso de la CuDa 2,2 y un archivo DLL de la Raistmer optimizado CuDa aplicaciones de este tipo .. Is THIS the machine you are talking about? If so, the 8400 card is very slow. You can try and optimise it by installing the latest drivers (185.85) and using the CUDA 2.2 DLL's and one of Raistmer's optimised CUDA applications such as THIS one.. Hey, at least I try. Rob

LOL It was no surprise as I wasn't actually expecting to work as well as it did under those conditions I subjected it to. 24/7 crunching in a hot garage. Went to a local store and grabbed a 700W PSU. Now it's all better.

29) Message boards : Number crunching : How much power! (Message 896851) Posted 19 May 2009 by KW2E Post: MyCore i7 920 with 2 Nvidia 295's, CUDA 2.2 and Rasitmer's v11 vlar kill is drawing between 700 and 765 Watts according to my meter. That's up quite a bit from when I wasn't using the 2.2 dlls. The Power supply in this machine is an X3 1000W. If I make any more changes, I'll need a bigger supply. Rob

I just installed a heat exhaust system on my machine that suckes the hot air out of the back of the computer and blows it outside. This has helped a great deal in cooling things down a bit in here. My 295's are running between 68 and 74 at full load now. Rob

That's a lot of (electrical) power consumption for very little return. A single quad (6600) will smoke all 7 of those by 2 to 3k RAC. I had a couple of those running for a while. Just wasn't worth it to me. $.02 Rob

37) Questions and Answers : GPU applications : Care and feeding of your CUDA cards. (Message 895766) Posted 17 May 2009 by KW2E Post: Hey all. I just got done cleaning out my Core i7 this afternoon. You would not believe the crap that those Nvidia 295's had inside them! Okay, maybe you would, but bottom line is, I have had them for only a few months now and there was enough crap in there to raise the temps by over 10 degrees. With the advent of CUDA 2.2, these cards started running really hot. Too hot. But the main problem was that hair, dirt, carpet fibers, styrofoam and other things were clogging the fins of the heatsink in the cards. Those squirrel-cage fans just wind any animal hair around them. What escapes the fan gets clogged in the fins of the heatsink. Problem is, unless you want to dig DEEP into the card, those fins are not easy to clean out. Moral of the story is, for those of you that have these things, and you're running on air like I am, you may want to shutdown and clean them out fairly often to avoid failure and high temps. I know there will be those that think this silly, but if I had left those things for too much longer they might have faied. I will be clearing mine out on a monthly basis now. Aside from that, I took the opportunity to zip-tie eveything up nice and neat and cut an exra hole in the bottom of the case so the lower 295 can get air. The Gateway FX-6800's have little room between the bottom video card and the bottom of the case. I measured back appropriately and carved a nice hole in the bottom so it too can feed on colder air. I have also finished my cooling project that I started earlier this week. Thios machine generates so much heat that the room is toasty all the time. SO I decided to build a venting system to force all that hot air out of the office. Using 2"x34"x12" of foam cut to fit my window, I installed a 6" drier type vent into the front, placed a good sized 6 inch high-rpm fan inside (insluated), then capped it all off with a 6"to 4" pipe adaptor. From there I use aluminium flext tube to the back of the PC where I have fashioned a cover to slip over the back of the machine and suck the hot air out of the case and out of the house. This will aid the fans in the case by generating some negative pressure on the back end, hoping more high-volume cooler air comes in from the front and bottom of the case. This has always been my problem with my main SETI rig. In the winter it's great, but in the summer it just unacceptable. But not for any longer. I will post some numbers and pictures when I get around to it if anyone is interested. Oh an yes, I cleaned up the floors and put away all the tools. Yea Me! Rob

The web is getting too polluted with my real name. You do a search for it and you get a ton of seti stuff. Tw34k3d is my XBOX Live! gamer tag. I think I need to start using it instead of my real name. Just something I have been cosidering for a while. No biggie. Rob

Up till now it would immediately end the WU with computation error. I tried this will various versions of CUDA, both stock and Raistmer's APPs with no success. For the hell of it, I decided to try it with the new 185.58 drivers and CUDA 2.2 DLLs and Raistmer's v11. VIOLA! It worky! If anyone else is having this problem, give this combo a shot and see if it helps. Rob
