Latest drivers (NVidia and ATI)

[Claggy]

yes, in true AMD way as usual.... compatible driver 11.4 listed... but they offer only 11.3 from official page still 

Tested drivers are Cat 11.4, but Cat 11.3 is additionally supported by AMD APP SDK 2.4,

Then for the AMD APP Profiler v2.2, Support for profiling with AMD Radeon™ HD6900 series GPUs (requires AMD APP SDK v2.4 and AMD Catalyst 11.2 or newer)

and for the AMD APP KernelAnalyzer v1.8, there's Support for AMD Catalyst 11.1 – 11.3

I wish they'd just test a few more drivers and actually say which drivers are supported and which aren't!!!!

NVidia drivers 270.61 WHQL were released yesterday.

This is the first WHQL-certified release from the Release 270 family of drivers (versions 270.xx to 274.xx).

I tried 270.51 when it was in Beta, and ended up with significant down clocking that could only be cured by a reboot. I'll give this version a go and see what happens.

I had the same problem as you Steve, kept coming in from work and finding my GPU running at 350/800, finally went back to the last WHQL driver version and it is sticking at my 800/1600 levels.

Might try installing the toolkit and then the newer drivers and see if it works okay.

I was getting this with the beta as well, everytime I had to restart Boinc the card would downclock.
So far though it looks like it's been resolved in this release

Alright, lookout.  So far these WHQL drivers appear to give me a higher throughput at the expense of higher temperature on my 480 with test builds.  I'm not sure I'm comfortable with my 480 running at 94 degrees C, so will have to keep an eye on it.  Time to follow through with that plumbing research  will have to hit the old lady up for some danger den funding

Okay, I loaded the new 270.61 driver yesterday. Got up this morning and noticed my work units were taking around three hours to complete. EVGA Precision is showing me downclocked from 900/1800/1804 to 405/810/324. The only good thing is that my temp is now down to 47c. It normally stays around 67c or so with the older drivers. Now, how do I get rid of this thing? Can I just load the older driver over top of this one or do I have to remove it first then load the older driver?

Straight install over the top *should* be OK, folowed by the advanced 'clean install' option if it didn;t take, then last ditch effort would be the 'old school' complete uninstall->driverSweeper->installNew tactic.

And to add insult to injury, on my (256MB) system it just doesn't want to play along with x32f.

Please pay attention to whether your tasks still validate after upgrading to 270.61!

Hi Miep and Jason G,
Mine validated okay but slow. Nvidia recommends just doing a rollback through System and Maintenance in the control panel so I will try that here in a minute. If that doesn't work I'll try to just install over.  And as a last resort I'll go find Driver Sweeper and do it the hard way.     If I'm not back in an hour send out a search party!   

Cancel the rescue party I'm back!     Rollback did not work the first time and when I went to try again the rollback button was blanked out so I hit uninstall instead and then installed the 266.58 driver. That seemed to work okay and it looks like I'm back up to speed. I like to stay up to date on the recommended stuff but I'm not gonna take that kind of a hit on my speed. Work that usually took 35 to 45 minutes were taking 2 or 3 hours. That's not good at all! Maybe the next driver will be better.

One more little note, I tried installing 266.58 over the 270 before I uninstalled and that didn't work either.

The Clean Install option does work as that is what I did on my system.

[SciManStev]

So far no problems for me. I'm over clocked, over volted, and charging up the hill, with temps not even slightly being a problem. No errors other than the occaisional -12 error. This water cooling thing is beyond excellent! It bullet proofs your ability to over heat, unless of catastrophic failure, which would be very, very rare.

Steve

[Pizzadude]

Yep, went for the clean install option and all looks goods.  Two overclocked 460's ticking along nicely with no increase in temperature or errors.

No performance increase or decrease.

[msattler]

Well, until I see some glowing reports about increased crunching production, I'll stick with the 257.21 and 266.58 drivers that are working great for me on a mix of 200 and 400 series cards.

[Pizzadude]

Mmmm three unexplained driver crashes in the last 12 hours.  Anybody else seeing this
