780ti tri sli problem

post #1 of 2
Thread Starter 
Hello.. Im having some serious problems with my 780ti tri sli.. My specs are 3930k @ 4.8ghz, rampage extreme iv, 32gb of corsair dominator and 3 x 780ti msi gaming.. Cpu,mobo and gpu all watercooled..

Two cards works like a charm and is really nice, its when i activate the third card things just arent working.. Lower fps in games than with two cards, think i got about 5-6 fps in firestrike on the last graphic test, completley undoable.... About 35-40 there with two cards.

Everything is running in PCI-E 3.0. Have the latest drivers, latest bios for my motherboard,, Every card works great for them selves so nothing wrong there And the PSU is a XFX 1250w..I Figured that would be enough because all cards are running at stock, no oc.

Runing windows 8.1 pro. Maybe someone has an idea whats wrong here.. Thanks anyway

Here is what you have to check for

1) make sure you have sufficient / clean power being fed to your cards
2) reinstall the drivers (perform a clean install)
3) make sure your 3rd card is not faulty, what happens if you run the 3rd card by itself, will it perform as it should? (sorry i didnt read the bottom part of your post)
4) make sure your SLI bridge is not faulty / installed properly
5) dont forget to restart after making any changes smile.gif

and Good luck... that should sum it up for you biggrin.gif
Hope that helps smile.gif
