NV 36 hour tdr bug resolved in linux

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.

Your make my day !! :mrgreen: :biggrin:

Thanks for sharing. Happy to get rid of daily reboot.
Any visible impact on performance/PPD as reported on earlier versions ? On GTX 780 or 660Ti ?

Others have reported a 10% drop in performance for non-780/Titan cards. That may improve in future releases, but some people are sticking with the older drivers, and still rebooting once a day. Time will tell.

I think those seeing a 10% drop were running Fermis or rather low-end Keplers. People running 770s, 760s, and 680s were seeing over 60% drops.

Whatever the case, it's still not a good option.

Its weekend, nothing better to do so I decided to reinstall my Ubuntu box to mainly switch to EXT3 instead of EXT4 and get a ramdisk in. Sidestory.

I also installed the new nvidia driver 331. Not yet even close run to full 36 hours but some data points I can confirm with the setup

MB: Asus P8Z77 V-PRO
CPU i7 2600S
Memory: 8GB
GPU0: 780 GTX
GPU1: 660 TI

just the first frames

on my 780 it looks very good: 8900 with TPF 3:20 and ~137kPPD; very much normal. :D
on my 660 Ti it looks ... awful ! :twisted: 8900 with TPF 10:20 (!) instead 5:47; 17 hours total time instead of 9 hours

So I think after the 660 TI is done I will downgrade to 319 again until some revised driver will be around. Just don't want to loose those points.
(My wife would say: I told you :wink: )

Update: I couldn't watch any longer my 660TI suffering;
1) stop the FAHclient
2) ppa-purge
3) reinstalled 319 from ppa:ubuntu-x-swat/x-updates
4) reboot box
5) start FAHclient

Now seems I get the original TPF values back with 5:30 for the 660TI and 3:20 (still) for 780; based on the log file. The PPD estimation and TPF value from client are still off; some more frame to align.

and so end the little experiment with nv-331 ... maybe next time ... :cry:

... there was only one good thing I saw with the 331 driver: the 660TI run 5C cooler ; which didn't surprised with the reduced speed
