GPU folding speed is dependent upon CPU speed

[chemist_slime]

I just got my E6300 clocked to 3.0 ghz and I can tell for sure that it does affect GPU folding.

E6300 @ 1.86: 8mins 45s per frame
E6300 @ 3.03 7mins 53s per frame

This is all on an X1950Pro @ default clock speed

You might post this over at the Folding at Home forumns; it's useful info.

I also noticed that GPU folding seems to be limited somewhat by processor speed. I have an 2Ghz AMD Venice and a 1900XT. Temps usually stay solid at 72-74 (I have the MSI IceQ3 heatpipe cooler on the card) when I am not using the computer. However, even basic web browsing causes GPU temps to drop to 63-68. While I haven’t closely monitored frame times, I would imagine that a temp drop that significant would indicate significantly less load on the GPU.

Temps quickly return to 72-74 when I stop using the computer.

Seems odd 2 other people are getting same times (8:00 +/-) with totally different CPU setups.

I was planning on putting my soon to be arriving X1900XTX (used) on a mobo that is running an X2 3800 @ 2.45ghz. I was under the impression that I'd lose too much production putting it on my C2D system (running 2 cores at 3.2ghz)...but having some firm info either way would be very useful. I don't want to handicap myself production by using up a faster C2D core if I don't have to...

use the X2 3800 .......will do just fine...2 units per day 660 points

I figured the X2 would be the better option. Though my C2D hasn't been as productive as I'd hoped it would be (lots of Amber units lately).

yea they suck........guess this GPU thing has got in the way version6 coming out
