AMD/ATI Pixel Clock Patcher

[Bluesun311]

Toasty... you are a mad genius and I'm sending you some more money. I was literally just about to come over here to ask if some of the issues I've been having could be pixel clock related and there's a new update waiting for me. Unfortunately I'm still having the problem after updating.

My new 290 has been kinda teetering back and forth between 60Hz and 120Hz and it's very strange. It will be working fine, smooth as silk in Chrome (does it in Internet Explorer, too)... and then just decide to start looking more like 30fps than 120. Have vsync and all that working fine, it works sometimes for 5 minutes or so, and then splat. The weird part is... the screen is still at 120Hz when it happens and ufotest is valid and stable and looks smooth going across the screen horizontal. But scrolling vertical looks horrible. Sometimes it will just randomly go back to looking smooth... too. No clue what's going on.

For reference, I have a 295x2 as well, and it will do the same exact thing--but turning off PCIE link state power saving fixes it with the dual GPU card.

This single 290 as well as a single 290x all do this. The single GPU cards I can't figure out how to fix it though. Any ideas?

I don't think there's anything wrong with any of the cards... 3d games work fine even with the pixel clock chumming along at 469.85Mhz (120Hz on my Catleap). Cards not overheating... it definitely seems to be related to the refresh rate. I'll try lowering it... but that's pretty painful. The monitor itself loves 120Hz. It's silent and runs like a champ in games. The only time I ever have weirdness seems to concern the voltage. When this happens, the card stops bouncing voltage up to the 3D clock 1.2v whatever and just stays steady at the idle voltage. Of course, I have tried MSI afterburner and turning the option to keep steady voltage on (which has zero effect), as well as unofficial overclocking mode, which causes BSOD.

Any assistance would be much appreciated
