SLI and memory....

post #1 of 8
Thread Starter 
So I am pondering on buying a 8800GTS 320mb for now and getting another so that I can go SLI later. My question is when you go SLI do you get 2x320mb = 640mb or do you just get that extra GPU? my understanding is you just get the extra GPU so to speak.....

you don't double the memory...each GPU holds the same info, and just alternates frames (depending on SLI mode)...but ya, basically they're storing the same info, so no the memory is not doubled.

Personally I'd opt for the 640 cause you can't just go and buy more vram...

You don't need the extra ram much if you are running 1280x1024 or lower.

To answer your question, I don't know.

This is correct.

For example, 2x 320MB 8800GTS in SLI, is still 320MB ram total.

Yea, don't go with the 320mb at that resolution.

All benchmarks show that 640MB does not have an impact until 1900x1200 resolutions. However, it does give you some leeway for future games that will use higher textures.
