can you run 2 sli's at a time?

can you do sli with, for example, 2 gtx 295's, and then another sli, with 2 9800 gx2's at the same time?
 
No.

You can only have one SLI configuration running, and they must be the same type of card. And besides, SLI is limited to 4 GPUs max. Two 295's or two 9800 GX2's would already put you at that limit.
 
alright. i was just curious becuase i thought if they were in 2 different sli settups it might work :p. plus that would allow more screens

Haha, you're a madman! I like your style ;)

Unfortunately no, it isn't possible, but who knows in the future we might see octo SLI or something equally epic... i'm waiting for it
 
ya but i dont see the point of that. if they were to do that they BETTER start supporting more then 2 screens while running sli. :p

Yeah at the very least 2 screens!! Imagine having 8x gtx 275.. and 4 monitors each running a different game with SLI performance... LOL

On another note, it scares me to think of the sort of games that would actually push an octo SLI setup to its limits.... o.o Probably just another badly optimized game like Crysis :p
 
lol ya it suckes that you can only have 2 screens right now. but 4 different games would be halarious XD.
but with that you could just get 4 295's :D
my motherboard could do that... i have 7 pcie slots hehehe. so im prepared if they end up making that :)

and with full anti aliasing.... some games WOULD use that many.

btw nice location XDDD

Two screens? I'm pretty sure you can get 3.. What is actually the main feature that drains fps? Anisotropic filtering or anti-alias? Or just high quality image etc?
 
Alright, and what do shaders do? Why does one want to overclock his shader clock?

You don't have to necessarily overclock your shader clock independantly, unless you specify otherwise it'll just scale with your core clock..

I'm not sure of the "dictionary defintion" for shader clock, but I know that overclocking it does help with graphics processing for a lot of games...
 
But you SHOULD overclock them each by themselves... you hit your limit much faster with them connected.
 
earthdog why do u seem to show up in all my threads... :)
and why would you hit your limit faster?
hey whats better.... running 2 screens on 2 gtx 295's in sli, or running 1 screen each one? i would think it would be faster with sli but i dont see how if its the same hardware...
 
b/c you post a lot and I hit the new post button as well as autosubscrbing to every thread I post in to f/u with...

It reaches its limit faster b/c usually the shader tops out before the core will when linked (shaders go up more usually). You overclock the shader first, find its limit, back it off a notch, then the core. Also with this latest gen of nvidia cards, teh core has to be 1/2 or less than the shader for some reason otherwise it wont accept the clocks.

With SLI you can run 2 screens for desktop, but you cannot play a game on both displays like you can with ATI's Eye-finity (someone correct me if I'm wrong here). If you have 2 cards not in SLI then you might be able to run 2 independent games on separate monitors, but I'm really not sure.

Once Fermi is released nVidia is supposedly releasing drivers that will allow more than 1 monitor while gaming similar to ATI's Eye-finity. But to get more than 2 monitors you'll need at least 2 cards in SLI. But at least there is no display-port requirement.
 
aw :(. that sucks... why doesnt it let you? i thought it was the game that determined that. and if u look at sli zone i think it says.
does anyone have an estimate on the price of the best fermi graphics card? will it start out really high and the get lower?

No...but you could run up to 4 SLIs at the same time :D
GTX 295 has built in internal SLI...so pop 4 into a machine and you technically have 4 dual GPU SLI setups on one box. LOL :D

octal-SLI would refer to 8 GPUs all running in a single SLI...I don't think that's what the OP was asking.
I think he was asking if "dual - quad-SLI" would be possible...but I don't think the driver support is there ATM :(

But if you had three GTX 295s, and you SLI'ed the first 2 for quad-SLI.....then left the third on it's own, you'd be pretty close :)

In fact, if you wanted to play with three monitors (like eyefinity) with nVidia, I couldn't think of a better way (with proper game support) than to use two 295GTXs in SLI for the middle monitor, and a single 295GTX for each of the side monitors...8 GPU power FTW :clap:....a few current games already support this (ie FSX)
