Is something wrong with my GTX460?

Well maybe someone can help me. I have a gts 450 that is way outperforming a gtx 460.

Vidia control panel/Manage 3D settings/global settings/power management mode does not exist, as i.m useing winXP.

Rebooting doesnt work, riva tuner does not see my drivers, which are 260.99 by the way.

I hope someone can help, Please?

Can you download and install MSI afterburner?

in the monitoring grapghs on the right, see what your clock speeds are for the 460. They should be in 3d mode, >675mhz on the core.
Also, do you have hfm.net installed? If so, what work units is each card processing?

Finally got a good and stable OC on my MSi card, and now I'm doing 12.7K PPD on these monsters Cant wait to see how much it will do on normal WU's...

Afterburner reports correct speeds. I switched the cards around and now the 450 is getting low ppd. The wu are p6800 and are worth 1298 points.

Here are the benchmarks for the 6800 project.

-- 460 --

Min. Time / Frame : 1mn 48s - 10384.00 ppd
Avg. Time / Frame : 1mn 48s - 10384.00 ppd

I am beginning to suspect that one of the FAH clients maybe bad, is this likely?

About 1.50 TPF is normal for a GTX460 on the 6800WU's. I'm guessing that you have overclocked the card a bit? But i dont know how the GTX450 are suppose to handle the 6800 WU's, 6.7K PPD does seam a little low.

Did you switch the cards around physically or in the client witn -gpu 0/-gpu 1?

The p6800 saturates the shaders of the 450 to the point it "chokes". It's probably going to be the future of FAH, larger and larger GPU projects that need more shaders for maximum performance.

Gamma you were originally doing ok with the 450 till you switched ...if your not sure whitch gpu is "taking over" pull the 460 just run the 450 . Then you'll know what it's doing.

Thread about low ppd on the 450 on p6800:

There is another about the 450 on p6811.

Here's how my 470 is handling these... this is at 700/1400. I can't seem to get the clocks to "stick" any higher than that... stupid card keeps downclocking itself back to stock.

These numbers definitely support what ChasR said regarding the larger WUs and the larger number of shaders on the higher end cards. Ignore the average and minimum. They are skewed by the card running at slightly higher speeds and then at stock. The numbers in red are what the card does at 700/1400.

Something else is odd about these WUs. Running a 6800 on my GTS 460 and GPU-Z shows it at 66% GPU load. It's normally at 97-98% when folding. Are they intentionally not fully loading the GPU? My shader speed is right where it should be. It's giving me 7282 PPD.

And fwiw, my 8800 GT on the same PC is getting a 404 error trying do dl a new core - fahcore_65.exe.

Another reboot seems to have gotten my GTX 460 back to 99%. Now doing about 10.5K PPD on a 6800 WU.
