You shouldn't need the patch with VGA unless you're trying to go beyond 400 MHz pixel clock.

I get the feeling this might be a driver issue related to CrossFire. Does this still happen with CrossFire disabled? Are you overclocking or overvolting the video cards at all or are they all running at stock?

I don't know what can be done if the driver won't load the settings on boot. Does running restart.exe reload the previous settings?

Hey Toasty,

So figured out it is not related to OC, or crossfire, but eyefinity only with 7680 x 1440 at > 80 Hz.

Proof:
- New driver install including DDU
- Crossfire single monitor at stock, no OC - got all 4 gpus going up the expected clocks
- Crossfire eyefinity at 7680 x 1440 @ 120 hz - no OC, got downclocking of GPUs, not that severe but enough to feel stuttering
- Crossfire eyefinity at 7680 x 1440 @ 80 hz - no OC, no downclocking of GPUs
- Crossfire eyefinity at 4800 x 900 @ 120 hz - no OC, no downclocking of GPUs

Any help would be greatly appreciated

Thanks Toasty

Toasty - to answer your second part - No when I run restart.exe, I do not get previous settings restored.

Hello all,

Has the black screen while playing back videos been clarified yet? I have the same behavior when patching my drivers (tried both the latest official omega and beta).

https://www.youtube.com/watch?v=CZBJ7Z0Hmhc

Happens in Chrome, IE and WMP, not in Media Player Classic though which would make one assume it's the codecs, however if I restore the drivers all work fine.

Setup:
- QNIX Qx2710 Dual DVI
- 7950 Crossfire

Tried:
- Re install drivers (both beta and stable)
- Re install K-Lite codecs
- Run on a single card instead of crossfire
- Change refresh rates (problem persists on 60hz as well)
- Disable DTV-DVD

Any ideas?

That shouldn't happen if you disabled the Microsoft DTV-DVD video decoders. Are you sure you disabled the DTV-DVD video decoders and not the audio decoders?

Yes but figured it out after having a second look, i preferred the dll ownership and renaming to .bak method, however I did it only in system32 and apparently should've done it in SysWow64 as well, my bad Thanks for the help and the tool btw

Any luck Toasty with the issue I have? If its nothing you can fix thats okay too. Thanks for all your hard work

I don't have a way of testing large Eyefinity resolutions, and I don't have R9 290 cards either. It doesn't make sense for the GPUs to clock down. That seems like a driver bug or possible hardware limitation.

Well it must be a driver issue. With AMD 14.4 drivers, no issues. AMD pixel patcher + CRU allows me to game at 7680 x 1440 @ 120hz. Too bad most of the games I play DAI and now GTA V dont run with these drivers

Just FYI for you toasty and anyone else that is interested

Try MSI Afterburner's UnofficialOverclockingMode = 2 and see if that forces the clocks to stay at full speed. That will also disable clocking down when idle though.
