R9280x single card/CF crashing LiveKernelEvent Error BCCode: 117

[Conall]

Hi everyone, Ive been a longtime lurker in these forums for the past three years. Finally got around to making an account.

Ive been struggling with pinning down some issues pertaining to my PC at present.

Ive been getting suboptimal performance from my Graphics cards for quite some time and am trying to pin down the actual cause.

Ive had various BSODs such as TDR Delay BSODs (which ive manually changed in registry), Ive RMA'd a graphics card and now i'm getting stability problems with a card that was known as working for a few months now... TDR delay BSODs are resolved, but getting the errors below now.

I'l list what ive done below, but am curious if this could be related to a dying motherboard, as my P8P67PRO is an early revision (has cougar point design flaw) and ive had a sneaking suspicion its on the way out.

So far I have:
- completely removed AMD drivers using DDU. Tried last 3 beta drivers, and stable driver. DDU used between installs to wipe it all.
- updated my Mobo Bios to v2303 (the latest compatible with my revision).
- problem persists when CPU is @stock clocks/underclocked.
- Memtested my ramsticks ( Rock solid, 9 Passes).
- OCCT/AIDA stability tested my CPU (No issues, tested >12hrs).
- I have two GPUs, an R9 280x DirectCU2 (DC2T-3GD5, this is an RMA replacement for a duff card; Replacement already has latest VBIOS on it).
another R9 280x MSI Twin Frozr. These Cards are rated at 1070/1600 and 1020/1500 respectively but have been manually clocked at 1020/1500 for stability.
- replaced PSU with new Corsair 750W 80 Plus , with support for Crossfire. Issues predate this.

This is what's recorded, but it shows itself as the machine freezing to a white screen with artifacting on it.


I'm loathe to blame the cards once again as that would mean 3 bad cards, which is statisically improbable!
Considering the MSI card behaves itself in my other machine with no problems, i'd have to extrapolate the problem is elsewhere in the system. What should I be looking for?

Windows was failing to boot up at one stage, and I did a system restore which resolved things.

So the current situation summarised:
-Crashes in D3D applications when crossfire enabled. GFX tempts stay below 78c underload.
-Crashes in DirectDraw (or aero) GUI when crossfire enabled, intermittent/random, seems to be only in crossfire; but has happened once with one card in the machine.
-less than expected performance (example: benchmarks of dota 2 @ max quality @1080P on single R9 280x is hitting 120fps easily (Source engine) and my game sits around 50-65fps. This shouldn't be the case with an i5 2500k @4.4ghz stable that stays below 70c underload should it?

Crysis 3 is unplayable (13-15fp) on all settings in single card or crossfire modes.

Any suggestions?
