Latest issue in post #29

Hi all, so up until now F@H has run my GPU (670 DCU2 @ 1250) on its power limit of 115% and pulled between 75K and 95K PPD, but recently it has only been running at about 80% to 90% power and it is only pulling 30K PPD. Gpu usage remains at 99% however.

The GPU works normally when gaming and stress testing etc, just not in folding.

Any ideas?

I think it may have been caused by the latest graphics driver update.

I am running the latest client (7.3.6) which I have restarted a couple of times, I have also removed and re-applied my overclock several times, and it has gone through about 4 WU's like this.

I can tell when it isn't being utilised properly as it runs about 6 degrees cooler.

Any help appreciated, cheers. :)

How would I determine which WU's im doing?

The GPU usage is still on 99% and it is sitting at 1200 - 1250MHz as usual, just the power is at 80 - 90 not 100 - 120 as per usual.

It has been doing this for several units though. I guess all I can do is wait and see if anything changes.

Sorry how would I check frame times? :p

It takes about 9 minutes per 1% of the WU at the moment if thats what you mean?
 
While I have you guys here, what would you say the best used folding card/s I could get for £150 in total is/are? I have 2x PCI-E slots, 2x 6 pin PCI-E power connectors and an 875W PSU to play with. :)

Another 670 perhaps?
 
Hello again all you lovely people.

So following on from this thread, the GPU had been folding fine up until today when it stopped downloading WU's. I tried all the usual things, restarting the client, restarting the PC, removing and adding advanced options, removing and adding slots etc, and in the end I gave in and updated the drivers.

Before updating the drivers they were on 327, and now they are on 331.8 (so a slightly later version than those which caused the issue last time - 331.5)

With these drivers installed I am getting the right PPD at around 80K estimated, but the power usage is hovering between 80 and 90% just like last time, and the system is practically un-usable due to lag, whereas before I could fold at 80K and watch 1080P video with little to no stuttering at between 100 and 110% power usage.

So if it doesnt play ball with this version, and wont even download units with the older drivers, what to do?
 
I had been on the 327 drivers from the 27th of October right up until today when I switched. I still couldn't get any WU's at about 9PM.

What period of the day was the server crash?
 
Whats going on? I backdated the drivers to 327 again and it was folding a mixture of 15's and 17's as usual up until about 2:30 when it stopped getting WU's, and it has been trying and failing to fetch WU's ever since, just like before. :(
