2nd 570gtx

post #1 of 3
Thread Starter 
As I sit here and wait for my new system to arrive I keep getting the urge to order another 570 and sli them... I have an asus 570 gtx with the voltage tweak from newegg... They are currently out of that card... My question is do I have to get another asus one or can they be any manufacturer as long as it is a 570 gtx??

Can be any gtx 570 for SLI.

Also yeah go and get another for SLI, you'll definitely max every game out as one almost does the job.

Two cards in SLI will always work in sync with each other.

As your Asus GTX570 has a slight factory-overclocking (from reference 732MHz to 742MHz), that 2nd card you are going to get will need to be able to run at this frequency as well. If not, Asus GTX570 will 'downclock' itself to match the default clock of the 2nd card so that both cards run at the same frequency.

However, I think, most (if not all) GTX570s currently in the market can easily be overclocked from the reference 732MHz up to 742MHz without a problem. In fact, they could be overclocked easily to a much higher speed.

And, of couse, if your 2nd card has a higher (>Asus' 742MHz) factory-overclocking, then the Asus needs to be able to keep up to that speed as well in order to take the advantage. But, again, even if unable to do so, SLI will still work but the pair will work at the same lower frequency.

As an OT, when you get your 2nd GTX570, perhaps it is a good time to get an aftermarket HSF for your i7 950 as it begs to be overclocked to keep a pair of GTX570s happier.

As a 2nd OT, I see that you are using Gigabyte GA-X58A-UD3R. This means that the 2 cards will populate PCIEx16_1 and PCIE1x16_2 slots for the SLI. As there will not be an empty slot space in between the 2 cards and despite the fact that GTX570 is much cooler card (than GTX470/480), I still advise you to think ahead of the ventilation. One is to increase air supply to them, particularly to the gap. One way to enhance is to change the HAF 932's side panel 230mm fan to 120mm fans (especially in the 2 lower positions). The 230mm fan can supply a large quantity of air but the air velocity is too small to penetrate into the gap. 120mm fans will be able (relatively speaking) to 'push' more air into the gap. Just a heads up.
