Hey guys n gals...
Pithy version: I purchased 2 4870 cards to run in crossfire in 2009. From the time I got it, one worked but the other didn't. Gave up on it, but couldn't throw it out. Now I'm needing the performance difference, but don't have the cash to buy anything else.
When I put the bad card in by itself, the PC doesn't start, and I get a black screen with red flashing letters that says, "you have not connected one of your video card power connectors to the power supply".
I'm 110% sure everything is plugged in, and since I have 2 of these cards and the other works fine, I'm confident it isn't my 650W PSU.
I flashed the bios with a 128K version, still no change.
I did notice that it is only showing 32 bit bandwidth instead of 256 like the other one.
I feel like this is a fixable thing, I'm just completely stumped, and the only thing I can find for an answer is PSU related, which won't solve my problem.
What do you think? (Thanks!)
Gigabyte EP45-DQ6 Mobo
2.86 quad core
6 GB 9600 OCZ DDR2
650W 80+ PSU
And trying to run 2 4870s in crossfire, but 1 won't work even in stand alone
