WHAT IS SLI......

[striker10001]

someone tell me the difference b'ween gts 250 [1gb] and gts250 [512mb] in sli..anyway bot are 1gb so.....thr diffference....???

SLI is when you use two identical nvidia video cards at the same time. So, needless to say, two gts 250 will be much faster than one.

For ati cards, this is called crossfire.

Huh? Would you like to try again? You should be able to SLI these two cards, the 1GB card will simply only use 512MBs of its Vram. (if any card is overclocked, it will downclock as well.) Difference? In SLI there is none.

oops. The post was a bit unclear so I just went and answered the "WHAT IS SLI" question. lol.

^ don't two 512Mb cards in SLI equal only 512Mb of VRAM? I was pretty sure when SLI'ing or CF'ing two cards it didn't double the memory...? Could be wrong as I'm also new to this.

No, you are correct, and so is the Rt. Hon 4745454b, although sometimes the slower card may increase it's GPU clock speed by a bit, I had a pair of 7900GT's that exhibited such behaviour.

ok if two cards r in sli which mean we'r doubling the performance right, two clock will be added as single clock.

 

[striker10001]

so what type of issues we get from sli, am planning over it!!!!

There's a sticky dedicated to the topic!

Ah, thanks mousemonkey - I hadn't noticed 4745454b already pointed out the fact regarding the memory

In some cases performance may be doubled (COD4 for instance) in others there may be no difference at all, it depends on how well the application has been coded to take advantage of the second card.

Scan line inter-leave, first introduced by 3DFX on the Voodoo 2 cards. 3DFX was bought by Nvidia, and later trademarked SLI as Scalable Link Interface.

That's the history, the rest of the thread explains your current options.

as doakwolf posted,guys plz read the FAQ before posting

ok thanks guys for ur good ideas....well am still a rookie, what should i expect in graphic cards for damn good hd gamming like antialiasing at top ,anisotropic filtring at top overall detail on very high...does gpu core clock does these thing or those or should i expect some thing else...for hd gamming for resolution 1360x768[samsung 933sn 18.5inch]
