so heres an odd one that I have been pondering a while.
in the realm of multi GPU systems do matched pairs (same make brand even specs everything exactly the same) show any sort of gain or efficiency to unmatched pairs (2 different makers or revisions or chip suppliers ect)
the reason I ask is because I am not only running a unmatched pair from brands but also generations. one card is a 7870, the other card is a R9 270X, one is MSI and the other is Gigabyte.
they both run at the same speeds, I make them do it but they do it (both OCed mildly) and yes, it works.
I couldn't really find a whole lot of info, just speculation. I did about 9 months ago get a TON of old bit coin mining rigs from a relative and one of them had a pair of powercolor R9 270s (and a 1000W corsair PSU oooOOOoo)
so I could try and see, make everything run the same speed. i'll have to set up a test bench because I don't want to use my main computer for it. I think there was a first generation i7 out there in all that stuff maybe i'll see if I can use it or whip something up with my own old spare parts.
what do you guys think?
