Message 35816 - Posted: 29 Apr 2011 | 13:18:38 UTC

So I took a few week break from crunching.

I fire back up yesterday and im running an AMD 1090T six core. and dual GTX 570's.

Im pumping out primgrid WU's in 10-11 min or so and also running 6 WCG tasks on the cpu's. Well overnight by morning my Primegrid WU's were taking 20 min to complete and their fans were running my slower and i noticed their temps were down.


Rebooted the machine and boom back upto normal 10-11 min times and temps to normal levels.

I shut my cpu tasks down for the day and ill see if that affects it. Just wondering if maybe the new Nvidia Drivers could be causing this.

Version
270.61 released a week ago 2011.04.18

the machine is running Win 7 64 bit.

Just figured id throw it out incase other people had seen the same thing.

I have a 460 that did the same thing. However I'd overclocked it to the limit. I backed off on the overclock and freed up 1 cpu core to handle the gpu requests and the time stabilized.

Had the same problem with 2 gtx 570's. First, are you overclocked at all? I was and was forced to increase gpu voltage to 1.075 volts. Then heat became a problem and I was forced to increase fan speed to 85% all the time. You should also go to Nvidia control panel and change "power Management mode" to Prefer Maximum Performance under 3d management.

The newest Nvidia driver will throttle the GPU's based on temp or voltage and that's what's happening in your case....it's protection whether you need it or not.

After changing these setting I was able to overclock to 900/1800/1900 stable. Heat was still an issue for me because PG will use 99% of the GPU and ends up creating a lot of heat on my midtower case.

Yup im overclocked, nothing fancy just 810 right now, just a wee overclock =)

Ill give your stuff a try when I get home and also see if the CPU's being free changed anything.

Silly new drivers and protection I dont want... I have no problems rolling 85% fans all the time =)

Hey Rick, can I ask what you did to free up a core?

Sure I can set it to use less of my cores but doesnt it just let that core sit idle. I like your idea of keeping 1 core free to feed the gpu's

I normally run either a primegrid job or prpnet stuff. The pc in question has 2 cores so to keep 1 free, if I'm running primegrid I only use 50% of the cpu. If I'm doing prpnet I only run 1 occurance. That leaves 1 core free to feed the gpu.

Of course if you have say 4 cores then set usage to 75% and so on in order to keep a core free.

Yes, basically that 1 core is not working or working very hard so you could say it's not being used but I've found that when running a really intensive gpu job a free core helps it run faster.

Hope this makes sense.

Something else you might try. I just noticed that every time boinc switched projects from GPUGRID to PrimeGrid the throttling occurred...every time and immediate. Took the card back to its reference settings and it still throttled. I reverted back to the 266.58 driver and I no longer have the problem, even when I return to the 900/1800/1900 overclock. Seems to be driver related.

For a long time i was running my 570 + 480 with times around 10-11 minutes per WU. After changing to stock app 1.39 the times are going up to 15+ minutes and the gpu-load is down to 50-70% from 99% before.
BM is 6.12.22, OS Win 7 64, driver 266.58
And please do not suggest me to update the drivers to 270.xx . After i had done the Gpuclock went down from 800 to 450 after some times. Its a buggy one

PS
Think i found the problem. Yesterday i fired up 5 vm's . Did'nt see that they are at priority level "normal". The GPU threads are at the same level, so they wont get the needed power from cpu. After reverting the VM threads to low the Wu times were geting back to normal.

So, two things.

the 270 drivers def are doing something funny. when I kept my CPU's idle the GPU's worked as hard as usual at the normal OC. with the CPU's going full bore my WU times started creeping up.


Rolled back to 266 and I rolled full gpu/cpu all night at my old usual times.. Ill stick with 266 for now ..
