Check TPF - 9205, 15minutes 12s. GTX 660 TI

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Check TPF - 9205, 15minutes 12s. GTX 660 TI

Post by GPU timpster »

Every now and then it seems my drivers for the GPU will silently "crash" and return to normal, and in FAH this makes the GPU slot go INCREDIBLY slow -- a reboot, nor even an uninstall (without) clearing the data will fix it.

So every time it does this I uninstall and clear data. I'm hoping that didn't happen twice already today. I'd like someone to compare TPF on some core 21 units on the GTX 660 Ti pleane.

GPU timpster,

Have you tried just pausing the GPU slot, waiting a minute, then restart of the GPU? Doing so will restart the GPU from the last set point. I found this adequate when having this problem. I would watch a hardware monitor to see how well the GPU is running. With the silent "crash", the GPU utilization would freeze at 99%. Normally it would be 88-99%, changing all the time. I recently dropped my driver to an older version to help the problem. With windows 8.1, I have not seen this problem in 10 days with the 347.88 driver.

Well, so far I don't know what TPF to expect with core 21 on Project 9205, so I don't want to unnecessarily pause it, but I'll do it, after the % is a tad past .10.

I'll update.

UPDATE: Still about 14m+. When it first started, I calculated a TPF of 700 seconds, or around 11-12 minutes. The next frame said about 18 m, and now it's back to 14.

GPU timpster,

Is your PPD for you GPU what you normally get? It is possible that this WU is larger than your usual ones. It does not seem like your GPU has the issue that I thought it might have had. I have had long TPF values for larger work units. If I remember, project 9205 was getting me 10 minutes TPF with my GTX 960FTW. That card is clocked at 1404MHz and has 2048 cores. It seems that your card is actually doing good, now that I look at the numbers.

EEDIT 1024 cores.

Because projects vary in size, a TPF comparison between projects is pretty meaningless. A better indication is the predicted PPD, though even this has its limitations. The predictions needs at least 3% under stable conditions to be anywhere near accurate, and even PPD will vary between projects, depending on how it was benchmarks and how well it scales of different hardware. However you can expect PPD to be stable within 10-20% across most projects and WUs on the same hardware, when folding is not interrupted and the non-folding work on the hardware is at the same level.

Here are some TPFs for my 660ti running in Linux using 304.128 driver:

9206 - Avg. Time / Frame : 00:16:05 - 56,611 PPD
9704 - Avg. Time / Frame : 00:05:30 - 73,834 PPD
10495 - Avg. Time / Frame : 00:06:05 - 78,780 PPD
11400 - Avg. Time / Frame : 00:07:27 - 74,514 PPD

Unfortunately I don't have any figures for 9205 at this time but suspect they would be similar to 9206.
