Re: Core 17 eats 1 cpu core with Nvidia GPU?

I had this same experience. I tried setting client-type to advanced for my GT 620 GPU on v 7.2.9 with a Pentium D processor. The PPD went from ~5.5K to ~2K, although there seems to be a small QRB with core 17. Interestingly, the CPU is the bottleneck as it can't use more than the equivalent of one ...

Re: Folding with Tesla K20C

Sure thing! One i power down theist em and reboot ill send entire log. With the hardware recommendations made earlier, I custom built a reducer fan and have been able to get the card balanced at 89 degrees under full load. With this, it folds a work unit in about 65 minutes. Is this a reasonable sp...

Re: Can old motherboards bottleneck GPU folding performance?

PCIe 1.0a and 1.1 both transfer data at up to 250 MB/s per lane. PCIe 2.x can transfer data at up to 500 MB/s per lane so you can mentally reduce the speed to half of what others are talking about. Sixteen lanes of PCIe 2 has been shown to be more than is needed. Reducing it to 8x is almost insigni...

Re: Can old motherboards bottleneck GPU folding performance?

I do GPU folding on two older machines, one on a Socket 939/nForce 4 motherboard (PCIe 1.0a), the other on a LGA775/Intel P35 motherboard (PCIe 1.1). The two GPUs I've used with them are a GTX 460 1 GB, and a GTX 570. I've recently switched the GPUs between the machines, and they do roughly the same...

Re: Is there a way to turn off GPU?

A bad heatpipe is a rare failure mode, Thermal paste failure is common for it ages till eventually it becomes just an heat insulator. Also, periodic cleaning with a can of compressed air may significantly help for dust and debris (typically hair) accumulation can significantly harm the efficiency o...

Re: Is there a way to turn off GPU?

My friend had a laptop a few years ago that had a bad heatpipe. It had apparently leaked out the fluid inside of it at one point. It was running at 90+ C, but the opposite end from the CPU was cool. Right above the CPU it was burning hot. He bought a replacement on eBay and it dropped temperatures b...

Re: Is there a way to turn off GPU?

If you are folding using both CPU cores and folding 24/7, then you should be getting closer to 2000 PPD. If you only fold a few hours a day, then 300 PPD is not bad. Just make sure you fold enough hours a day to make the deadlines. This. My laptop is running a C2D T7600 (2.33 GHz) and usually does ...

Re: GTX 780 & Core 17 problems

Personally, I haven't had much luck with the 320-series drivers. 326.19 beta came out yesterday, give those a try.

Re: Getting small WU's on a Geforce Titan

I'm under the impression that GTX 460 level GPU is the watershed where you start to gain any benefit from GPU QRB. Based on my experiences with my GTX 460 1 GB, I agree with that. It gets about the same PPD with core 15 WUs as it does with core 17 WUs, and that's with it overclocked a bit. My GTX 5...

Re: latest working nvidia driver

I'm running 310.70 with a GTX 680 and 460 (in two different PCs, one Win8, one 7). Everything seems to be working fine here.

Re: returning to folding, problems with 680?

I installed Windows on my PC on December 10th, with a fresh install of F@H at that time. I just deleted GPUs.txt a second time and watched it get recreated, the client still lists GF114. I'm not too concerned about it as it's folding fine for me. I opened the file and verified that the card is liste...

Re: Problem with the new WHQL R310.70 driver on GTX460s

I've had the opposite experience with the 310.70s on my spare PC's single GTX 460. So far, they're running flawlessly (and turning out ~22k PPD on the current WU). I had upgraded from 295.73. I tried a couple of 300-series drivers before (301.42 and 306.23 I think), both were very problematic with F...

Re: returning to folding, problems with 680?

My copy says GK104, and I only have one copy. Everywhere I've looked in the client and GPU slot log references GF114 for the video card though. Perhaps a bug in the client?

Re: returning to folding, problems with 680?

My 680 (EVGA Superclocked+) is also being detected as GF114. I'm using 7.2.9 and just deleted GPUs.txt followed by a client restart. Having said that, it appears to be folding fine (and generating a TON of PPD). I'm on a new Windows 8 x64 install, using the 310.70 drivers. http://i46.tinypic.com/213...
