I have older hardware and see litte reason to update it atm but I have one annoying problem.
I have a 7970 and a 280x in my system the problem is the 280x clocks quite a bit better but by default the 7970 is used as the primary, in real world use cases for me my 280x rarely sees more than a 4% load and even that is uncommon. My system would most likely be faster if I removed the 7970 entirely or switched to single card mode and used the 280x. Is there some way I can make my system use the 280x as my primary video card wile crossfired?
hmm well I'll take your word for it. I do have use cases where both of them being in there is beneficial and graphics performance being a bit slower dose not effect me much so I'm just gonna leave it as is
No it won't it will always use the 7970 for most tasks. You can't even use the 280x for anything in single mode unless it's in software that specific ly designed to be able to use it outherwise it will just be disabled. AMDs driver's is designed this way when you mix these two generations of cards the older generation is basically the master
Yes these is no way to use the 280x by itself without removing the 7970. If you disable crossfire the 280x is disabled and there is no way to switch over too it that I know of. You can use it with programs that use gpu power for non graphical things but thats it.
ruing the two generation cards together comes with some querks. The reason for this post was too see if anybody knew how to get around those.
Anyways when you have of both of these cards installed the drivers are designed so the 7970 is always first and also any 280x specific features are disabled. I knew that b4 I even bought them. I think I recall he who shall not be named syndicate did a video about it. This is what AMD intended, if there is a way around it its a hack of some kind.
Well sorry mate. Haven't had that kind of issue before. The closest issue that I had and I can think of was before when I installed my GPU drivers automatically, It will always gave me the drivers for 7970 and not the R9 280 drivers. So I had to uninstall the 7970 drivers and install the r9 280 drivers manually.
