Some 570 use 6+8pin and sone 2x6pin why?

post #1 of 4
Thread Starter 
Hey is the title says i wonder why some gtx 570 uses 2x6-pin and some use 1x6-pin and 1x8-pin.

I have an Asus GTX 570 refference and i am considering buing another one if i get a good price. my chance now is a gainward refference but the gainward one uses 1x6-pin and 1x8-pin.

so my questions is:

will these work in sli?
and
Why and what is the difference?

Power plug configuration was designed based on calculated TDP and power phase design (depended a lot on the stock clocks - stock clocks versus super clocked, FTW versions etc.) and my guess is that some thought went into the cooling solution too (single fan, dual fan etc.)

At any rate, the short and simple answer to your question is that Yes you can SLi both of the GTX 570 cards regardless of the power plug configuration.

They are both 1.25Gb memory and the only other caveat will be the gpu and memory clocks of each card. They will have to be exactly the same, so the nVidia driver will match the two by down clocking the faster card if necessary.\

All isn't lost though, you can use a 3rd party overclocking utility to set both the gpu and memory clocks of both cards to the same value. Whatever you do, do not try to flash an Asus BIOS to the Gainward, or visa-versa.

YW. Is the Gainward card one of their "golden samples" or "goes like hell" editions?
