Hi Guys, here's a bit of background:
System:
Win 8.1 x64
16gb RAM
Asus P8p67 EVO
i7 2600k @ 4.7ghz HT ON (and OFF)
Diamond R9 290 Reference
Asus R9 290 DIrectCUII
14.1, 14.2 and now 14.3 drivers
Symptom: BF4 (either in Mantle or DX11 mode) switches usage from 0 to 100% alternating between the two cards. So never see two cards running above 0% at the same time except for a split second as they're ramping up/down.
Updated to the latest 14.3. Disabled ULPS again; first through Afterburner and then through regedit to make sure all references to EnableULPS are set to 0.
Turned on Hyperthreading (might as well try anything). Even changed BIOS one revision back to rest with it and then back to the latest, no change. Unplugged 2nd card after returning to the latest BIOS to re-enumerate the PCI-E bus. Still no luck.
I know other people are not having any issue with 290 in crossfire on a p67. One guy I talked to has the Asus Pro and I have the Asus EVO mobo (difference is that EVO has two NICs and onboard Power/Reset buttons). So it isn't that the hardware doesn't support it or anything. It seems to be a setting/driver issue but the guy who has it working on a P67 Pro is running the latest 14.3 as well. He's running BF4 with Mantle, same as me and getting usage on both always.
I've seen other people report this issue but seems there's no known fix yet (that they've updated their posts with anyway) They were using the same two cards so I don't believe the issue is that the 290's aren't the exact same model. I see higher scores in 3dmark but not in BF4 or Skyrim.
I'm willing to entertain any ideas
Thanks for stopping by.
