Welcome to Redline from another old FM/MO'er

IIRC I had the same problem when I bought my 1st 560TI right after they came out and installed it along side of a 460. The 460 ran slow.

I fixed the problem by buying another 560TI and the 560's are still running fine together. I'm sure that's not the answer you are looking for......

Thanks.

It's not quite the answer I was looking for, but I think that's confirmation enough for me to stop scratching my head and finding a solution to the problem.

I'd be interested to know how things would go with a 460 768 and a 560 non Ti in the same box, or a 560 Ti and a 560 non Ti. Would possibly help narrow down the cause.

As for the V7 beta. I still have the same issue.

Its frustrating because I picked up the 460 on the cheap (ish) just for folding, and in its current state it's not worth the price I paid over the 8800GT it replaced. Oh well, live and learn.

So do I, but I've blown my budget on the 2600K.... and everything else (cough - unplanned SSD - cough)

Thanks.

Just a thought - have you tried monitoring the 460 in Afterburner to make sure it's not defaulting to 2d clocks? Sort of a long shot but can't hurt to check.

Yeah I have. All is present and correct. I even have the 460 overclocked to 800mhz to try and make up some of the gap.

HWMonitor shows the voltage is at 3D clock speeds and the temp is right around where I would expect it to be under load (73c with the 560 Ti folding right under it too). Close the folding window and its back down to 2D volts and the temp to about 40c.

Tripple checked with gpu-z too.

Thanks.

Assuming you meant 470 above.....

A 460 and 470 would probably work together, although I'm not positive. The 5xx cards are a little removed from the 400 series. When the 560TI was first released it had it's own set of drivers, the 500 series cards had seperate drivers for quite some time before being included with generic Nvidia drivers.

No, I did mean 560, because the 560 has the same number of cuda cores (or what ever you want to call them) as the 460. Unless I'm remembering it wrong.

So 460 + 560, slightly changed core, same number of 'processors'

vs

560 + 560 Ti, same core, different number of 'processors'

Anyway, it doesnt matter all that much, was just my brain wandering down a path trying to find a way to figure out whats causing me to lose PPD.

Just had a read through this thread...the OP had the exact same issue as you. Unfortunately it's starting to look like some sort of unfixable bug.

There are quite a few suggestions in there but it sounds like we pretty much covered them. Not sure what else you could try...

Thanks for putting in the effort. I knew it would either be something easily fixable but totally obscure, or just not fixable.

I had tried and checked many things before posting, but figured I'd try my luck just incase someone here knew of a cure.

I wonder if performance is held back for other cuda functions like Physx....
