i have 2 cards of R9 MSI 280x 6GB each.
i use them in Crossfired.
i have noticed that one of the card is working more slowly than the other.
300MHZ GPU Core Clock, instead of 500MHZ as the other card.
150MHZ GPU Memory Clock instead of the 1500MHZ as the other card.
both of them are totaly Identical.
i tried to play at batman Arkham Origin which is 3D game (but i am using it in 2D Monitors).
i did my tests with GPU-Z software.
this software could create Log File to monitor at RealTime the performance of each card while playing in High Graphic Quality games
the log file shows that the problem remainds.
i have no problem of PSU since i am using Corsair AX 1200i which is WATT 1200 WATT PSU.
i have i7 740 CPU .
12 GB RAM.
motherboard: ASUS rampage II Extreme.
i have noticed that this problem is well known in other forums (using google) and not just necessarily in this specific card only, but with other ATI cards.
have no problem with over heat. everything is being cooled properly.
i never had a problem in my previous SLI Cards (gtx 760) on the same computer.
so guess no blame on my board or cpu, PSU components.. just the ATI thing.
AMD Support or anybody, please any solution for it ?
