The faster one is with Elpida memory chips, the slower is with Hynix.
I have both kinds in my setup.
If that's the case would both cards work when I've flashed the exact same bios on them both? I backed up both bioses but modified one and flash that to both.
Edit: Nevermind I guess. They both started suddenly started hashing at the same higher speed over night. I haven't done anything. Haven't touched the PC, not even logged in with Teamviewer. The slower card suddenly just started hashing faster for some reason.
