Low PPD for 670

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.

Low PPD for 670

Post by cjmc45321988 »

On a core 17 WU (project 9201), i'm seeing TPF of 1 minute 39 seconds which is about 330,000 ppd.

I set the fan speed at 60% and GPU temp is 62C, with 98% gpu usage. Amazing card!
How is everyone getting these types of numbers? My gtx 670 has never done more than 31000 ppd. I am getting roughly 20 min TPF on these core 17 projects. Should they be higher?

Later drivers do not work well for folding with pre-GK110 GPUs ... any GPU older than the GTX 780 and that would include the 670.

My 670 running on Ubuntu 14.04 with the 304.117 drivers (included with the o/s in Additional Drivers) produces ~88K PPD. If using windows see this thread. The 327.23 drivers appear to be the most productive on Windows for your generation of GPU and your PPD should be in the low 80K range.

For additional help please post the System Info and Configuration Sections of your log along with a few lines of the actual folding section. See the link in my signature if you're not familiar with that procedure. Also, please report the version of nvidia drivers that you're using.

Do you have a passkey and has it been qualified?

Is there at least one CPU free to support your GPU?

Ok. sorry I forgot to rely to this, I've been real busy. I just got my GTX 970 today and get around 53k ppd on project 9201, which from what I've been reading, is still not nearly enough. I am utilizing all of one core, but I can no longer find the option to unlock it from one core. I assume the CPU is bottlenecking it. Can someone tell me where the option is for that? I also am not getting any QRB, even though I haven't changed any of my settings. The last few haven't made the QRB deadline because I have been doing some heavy duty video converting, I just assumed I was still above the 80% threshold. Also, is it normal for the GPU to stop working altogether every 30 or so seconds and then startup gain? I know its not a heat issue because temperatures never get above 65, so I thought it might be the folding because the display isn't interrupted or anything like that. Thank You.

One core should be enough -- indeed I know of no way to use more than one for each GPU. The CPU seems to run a polling loop, waiting for the GPU, so it's not permanently doing useful work. The 30s intervals are when the CPU is servicing the GPU. To change CPUs available if you have multiple GPUs, set the CPU option to use fewer cores (but avoid large prime factors , usually 7 and above). 53k ppd might be right without QRB, so that should recover when you can meet the deadline.

@cjmc45321988:
I checked on your passkey(s). You have used 5 different passkeys probably including a blank passkey. I don't know why you've used so many (perhaps due to mistyping it.) Three are qualified and two are only associated with a few WUs. If you've changed usernames, too, I have no idea of which passkey was used with which username.

Thanks for your help. I was getting the bonus before, and I haven't changed anything in years, so its probably the deadlines.
