EXTREMELY slow GPU slot--happens after it basically crashes

Postby GPU timpster » Mon Nov 02, 2015 10:54 pm

Hey, whenever my overclock goes too far the core basically goes into slow mo, I'm talking, for example, 12 minutes TPF on core 18s, and currently "1 hours 10 mins" on core 18, project 10476.

I've deleted and re added the core SEVERAL TIMES, even deleted it, and rebooted, SEVERAL TIMES, and it's still stuck in the stupid slow mode. When the thing basically crashes, my GPU clocks revert to stock, so there is no overclock currently. How do I get back to the normal performance, and also why does this happen?

Also it seems no amount of deleting / re adding the core does anything, here's another example "2 hours 26 mins" Core 18, project 9140.

You'll probably need some logs so here it is!
I'm guess I'll use code to put it in a box

There is a known issue with a "go-slow" mode (possibly associated with excessive GPU memory use) which, on Core21 at least, will eventually result in a "Bad State" error and a return to a previous checkpoint. Normally a pause and resume will return to the last checkpoint and normal speed, until it strikes again. Too many occurrences on one WU will result in a Bad WU error and premature WU end. A possible cure is to reduce the overclock, sometimes even to below stock frequencies (this is for older nVidia cards, the Maxwell cards seem to need a reduction of Memory clock, but this is not yot conclusive).

I notice that the log you have posted does not show the go-slow, since the log ends just as the WU starts.

I'm experiencing the same issue after completely uninstalling and checking the data box, it's 43+ minutes EDIT, TPF, core 21 project 9635. What gives?

Alright, it's normal again, finally! I hate when that happens! I always takes me about 3 hours to get it going right again, always leads to me uninstalling and reinstalling.

Your overclock might be unstable ... it might be a good idea to stick to stock clocks for a while and see how it goes ...

OP: how long have you waited for the TPF to update--and what does the log say? You can check TPF times in the log, but give it 20 minutes or so to update, and it may go away. If it does not, just restart without pausing the stop that is affected, and that should fix it.
