Different series cards same rig?
-
I have a sapphire 7970 right now, and just bought a asus r9 280x… will I be able to have them both mine on the same pc?
-
Sure, if you can get them plugged in and the drivers don’t completely barf. You’ll probably need a riser cable to plug it in unless your MB has 2 PCIe 16x slots.

I say, you are on the extremes, let us know the drama!

The R9 280X is essentially a 7970. The sapphire dual x R9 280X that i got had a bios switch and it now behaves exactly like a 7970.

In theory they should work just fine, but we can see from how bad the xfx 7970s hash scrypt that not all cards are created equal. You may find that the new cards prefer some different settings. I know my MSI 7970s will probably not play nice with any other cards as they love to run at the odd TC of 21105…

Yes you can.
I have mixed gigabyte 7970 and their 280x versions. You may need to play with the config though as it’s possible that the cards need differnt settings.
E.g. my 7970 needs 1100/1500 for 760Khs but the 280x need 1055/1500 and maxes out at 735khs (1100/1500 gives me 680Khs). One day i’ll tweak to get more but cant be arsed for 25khs. ;D

as far as drivers. the only problem would be if you mixed a legacy driver card with a newer card. i believe older legacy drivers don’t have the newer drivers in them. but you could probably manually install them. heck i was hashing on a pair of 7870s with the windows drivers and getting the same hash rate as the amd drivers form ther site lol
