Evening, i really need help with a SLI performance problem. I purchased 2 Palit gtx 680 jetstream 4gb graphic cards today from Amazon. Before i installed the cards i uninstalled all nvidia drivers for my gtx 590 (usb drivers, 3d vision etc..). i have installed the new cards with the SLI Asus ribbon, and the latest nvidia drivers from their website for my 2 gtx 680 (version 306.97).
But i am having the same performance as i was getting with my gtx 590, i know that one gtx 680 is not as fast as a gtx 590 but i have enabled SLI in the nvidia control panel, and have downloaded GPU-Z to make sure they are running in SLI, but i have no increase in frame rate performance at all. Is it something i am doing wrong.
Just wondering if it could be my system setup or a problem with my new cards. Here is my set up
Antec high current gamer 900w PSU
Asus Extreme III
Intel core i7 960 @3.2Ghz
6GB DDR3 2300Mhz Corsair Dominator GT
2 x 1TB Black caviar 64mb cache in RAID 0
2 x GTX 680 Palit jetstream 4GB cards
Windows Vista Ultimate 64bit
Evening sorry to trouble you. i have disconnected the sli bridge cable and left one card (the one closest to the cpu) connected to my psu and that card starts my pc fine with the display working, but when i plug in the other car (the 3rd pcie slot down) i get no signal and the pc does not even make a peep some or start windows.
is this normal?
I hope this is enough info, thank you in advanced.
bf3, nfsmw, guilld wars 2 i am getting the same speed with my old gtx 590, but imy main concern is i am only getting a display signal with the card in the 1st pcie slot, and no signal of winodw loading with the card in the 3rd pcie slot.
there is no difference at all. both cards according to sli visual indicator and nvidia control panel is working in sli but if i unplug one gtx 680 and just use the one, the performance is the same as i was when trying to use sli
