Stupid Question About SLI..

post #1 of 11
Thread Starter 
Hey guys,
I don't fully understand SLI besides linking multiple nVIDIA cards together. But i was just wondering, where does the secondary card get plugged into? and will there still be enough space between them if i just leave the cases they came in on? The current GTX 460 i have is an overclocked Gigabyte one with the dual fans, and the second one i wanna buy is just a standard reference card.

How do people fit like 3-4 cards? I thought i heard one guy even say once he had 8?!

Your motherboard only has one PCIe x16 slot so you can't SLI. Mobos designed for SLI/xfire usually leave enough room in between slots for the cards to fit.

mobos like this can fit numerous cards

Most high end cards have 2 sli connectors cut onto the pcb, thus allowing 3 or more cards to be connected in sli/crossfire. Assuming your mobo has 2 or more pcie x16 slots.

Oh nonono guys, i already knew that about my mobo... I'm building a PC this year. I'm getting an ASUS Rampage III.
It can apparently support having SLI and CrossfireX at the same time or something..

but the plan is to just get a second GTX 460.

You'll definitely be able to SLI two different manufacturers' cards, one reference, one not, as long as they share the same GPU (no SE with non-SE) and same frame buffer (1GB/1GB or 768MB/768MB)

Of course, with factory overclocks, the higher clocked card will downclock to the slower card's speeds.

u iz buyin old 1366 PC? NOOOOO!
go sandyballs- i mean bridge, or wait for bulldozer!

playing the waiting game is what you should do!

btw, my CH4 may say its CFX only mobo, but you can use the SLi hack to make SLi work on ANY motherboard that doesnt officially support it!

i SLi'd my old GTX275s on this fine! i kinda miss how sexy they were...

not all the time. my EVGA and BFG 275s were clocked differently, but they still kept the same clocks!
BFG was 648Mhz core, EVGA was 626Mhz ore something like that. i manually made them both the same tho.
