GTX 580 SLI Question

[MainframeTM]

Greetings,

I currently have a Asus GTX 580 & am looking to add a 2nd one. My issue is that I can't find another card for sale. However I've found this... http://www.cdw.com/shop/products/PNY-GeForce-GTX-580-graphics-adapter-GF-GTX-580-1.5-GB/2239145.aspx

And I"m wondering if I can SLI these cards together?

Thank you.

Yes, so long as it's the same model card, ie. two GTX580 cards, the brand doesnt matter.

Normally, the above statement would be true, but there are always exceptions. If both cards are reference, you're good to go. The cards will obviously run at their perspective mfg. settings, so different clocks, etc. To make both cards run at the same clocks, you can either set the card clocks, or flash the cards with the same BIOS.

If you're not pushing any serious clocks or voltages, you're probably good to go mixing non-reference cards as well.

If they aren't both reference cards, and you're doing any overclocking, you can run into some problems. For example, we've (a few team PURE members and I) with several GTX 580, and when mixing Asus Direct CUII with reference cards, we could only software adjust voltage on one type of card, since we had to use different tools (SmartDoctor for the Asus, and Afterburner for the reference). Card clocks were adjusted together no problem though.
