Attempting to crossfire 6950s...warning led?
After seeing the frame rate boost my brother has with his single 6950, I decided to order myself two XFX DD 6950 2GB. The issue I've come across is that my motherboard seems to only recognize one of the cards. The power supply in my rig should be more than sufficient to handle two of these cards.
Enermax Galaxy 1050w 80+ Platinum Certified. To rule out some of the usual issues.
Before installing the new card:
-removed the old card drivers, used driver sweeper after the uninstall
-disabled integrated graphics
-removed the overclock on my i7
After installing the new card:
-checked that all power cables were connected properly. (Each card has two six pin pci-e connections)
-Checked that the cards were in the proper pci-e x16 slots. (running at 8x confirmed in bios)
-Both cards work if installed seperately (one at a time) and the rig will boot when both cards are inserted. (Fans spin on card that is red lighting)
Now, one of the cards is showing an LED error code (red light). I've tried switching the power cables to each card, and it seems the card with two specific cables cause the error led to present itself. Is this a power supply issue?
One more question: my MOBO has an 8-pin e-atx power connector at the top right corner,(the other four pins were covered with a cap of sorts) however this has been running with the standard 4-pin without issues. Could this cause the issue? Unfortunately I can not seem to find my 8-pin cable that came with my PSU, and will order one if need be.
Any insight would be greatly appreciated.
I've spent quite a few hours over the last couple of days searching for answers as to what this warning LED indicates, however I can find no documentation, even through the XFX support site.
