New 6970 in CF - No display

post #1 of 5
Thread Starter 
Hello you people!

I recently purchased two Sapphire HD6970 cards and planned to run them in CF. I uninstalled my previous drivers, and removed the card. I then proceded to add my two new cards with the CF bridge and boot up. Sadly this does not give me any display at all. I can run one 6970 card without any issue. Please help me! <3

My motherboard: ASUS P6T DELUXE V2 X58 S-1366 ATX
My PSU: ACE MIDITOWER GAME EDGE 990 ATX BLACK (850 WATT)

I'll provide any more information if needed!

have you tried running with two in but not bridged first and did you check for video on both cards?

Thanks for the fast reply!

I've tried both cards seperatly, and they both give me display that way.

Running now with both cards connected but without the bridge, getting display too. I've got two bridge cables, should i try alternating between them or perhaps use both?

Edit: It's wokring, it's woooorking! *Anakin skywalker voice*. I alternated between the briges a little bit, and all of the sudden i got it to work. Maybe i did not plug it in hard enough or something...

Anyway, thanks again for the fast reply! <3

You only need one CF cable. Are you plugging your display cable into the primary graphics card? In crossfire only the primary is used for display.

It's highly possible i plugged it wrong. It's working now and i'm not quite sure why. Of course i did something wrong at the start, question is what.

Thanks again everyone! <3
