Should I sli two 570s 16x4x with a 460 in another computer x 16 or should i just x16 both 570s?

best i can do right now

I don't think the project supports sli so I would say no. Just get all of those cards crunching

but i have one computer with two lanes of 16 and 4. one computer with one lane of 16. i dont think the 460 and 570 could both crunch in the same machine with the same drivers.

I think the 460 and 570 can be in the same computer at the same time. I have mixed 570s and 580s but I don't know about 460s and 570s. You may need to run 2 drivers and that should work with Win7 or XP. I think Vista has a limitation of only 1 video driver.

Has anyone else mixed 460s and 570s?

the problem is they are different series

I am running one system with a 570 and a 440, and another with a 570 with 2x 220. Never had any issues related to using the same driver.

But, I would believe that you would take a bigger performance hit if you run a 570 at x4 vs. a 460 at x4. I would think you would want to separate those 570's to get maximum benefit. Someone can correct me if I'm wrong.

But, you could just try it and see.

Well I tried it, and I didnt get any work from the server. Then I tried folding@home and after some tinkering I did get it to work, and lucky me theres even room for a vga fan from newegg, and it is needed running at 100 percent, i was like 1 degrees over the recommended 97. I would of liked to stay with gpugrid, but it is all for a good cause in the end.

When i get my second 570 in the mail it will be crunching for gpugrid. Something my smart ass brother told me, its not good to put all your eggs in the same basket.

You're not allowing your fans to dynamically adjust are you? Depending on what brand you're using, you need to have those GPUs running at a steady fan speed. Do not let them control themselves. Otherwise you will have HIGH GPU temps.

i was like 1 degrees over the recommended 97.

Yea, I got a mobile air conditioner and a window air conditioner, cause its starting to get really hot. Ill just have to keep the mobile one pointed directly at it, as i can because the temps are rising, until i get a vga fan. It was downclocking it got so hot.

I also wanted to say now that i remember that it wasnt heat that was causing downclock it was msi afterburn core frequency overclock that i had saved. As downclocking is the eternal enemy of a cruncher
