Nvidia SLI

[JustTheTip]

Hi guys,

 

Just a quick question about Nvidia SLI, when you put two GPU's in SLI do they have to be exactly the same type of card, or only matching chips, or even just the same series or can they be random cards mashed together.

 

If it helps i have a GTX GeForce 770 EVGA SC

 

Thanks

It has to be another GTX 770. That's about all.

They need to have the same GPU, (770 with a 770, 780 with a 780, not 780 with 780Ti) and if they have different VRAM amounts it will use the smaller amount. It will also force both cards to run at the same clock speed, the faster one adopting the speed of the slower one.

only matching chips, although if you combine a 2gb and a 4gb card, you'll only use 2gb of vram.

 

also, Ti versions of cards are considered different and cannot be paired with non-ti variants.

it has to be the same version of the card you have and it has to have the same amount of vram

Same chips, as long as you get another one that is a gtx 770 no matter what branding it should work. But unless you have insanely good airflow just get a reference card for sli so it won't blow the heat into the next card.

same it has to be a 770 with he same amount of vram but reference or non-reference it will still work

What actually changes in the Ti versions?

Incorrect.

Mismatching memory sizes can't pair up. A 2GB card must be used with a 2GB card.

They do NOT force the same clock speeds, and instead will simply work at each independent clock speed. A great difference in clock speed will cause stuttering however (but this is usually something like 400MHz+ difference; not normal pairings).

Same model (770 by example) and same amount of memory. Manufacturer doesn't affect this.
