AMD/ATI Pixel Clock Patcher

[Skyy]

Hello everyone! First of all thanks to Toasty for creating the awesome CRU and Pixel Clock Patcher! A friend recently introduced me to the idea of monitor overclocking and while I thought it was only feasible for 3D monitors with Lightboost and dismissed 70-75hz as being better I quickly noticed I was wrong, hitting 70hz for the first time I was in disbelief at how smooth window dragging and the Windows animations suddenly were. Now I want more but I have a problem going anywhere over 70hz so I decided to ask here for help.

I'm using a Club3D 7970 Royal Queen along with a LG 23ET83 IPS Monitor, connected with a HDMI to DVI cable, the HDMI end being on the monitor and Catalyst 14.6 Beta 1 with Windows 7 64bit. I did not use the Pixel Clock patcher yet but only CRU for now. If I add a custom resolution with 70hz and reboot I can select 70hz fine and it works perfect, now adding anything over 70hz, even 71hz doesn't even register in Windows. I tried adding 70, 71 and 75 with CRU and when I go to the Hz dropdown menu on Generic PnP Monitor everything above 70hz isn't listed even though CRU still has them listed as inserted. I used LCD Standard as my preset when adding 70hz, 71hz and 75hz.

I assume this means I have to use the Pixel Clock Patcher? If yes, reading around a bit here this means the following for me correct?

- I lose Flash hardware acceleration (I have that disabled anyway as it annoys me that my GPU clock gets stuck at 501mhz whenever a Youtube tab is open while not even playing)
- I can't use the Raptr Gaming Evolved App anymore (also a non-issue since I don't use it)

Now some questions I have beyond that:

- Will I also lose DXVA video acceleration in Media Player Classic for non-HDCP videos that aren't .wmvs?
- Can I still use AMD VCE hardware accelerated recording in MSI Afterburner?

Also some interesting thing I noticed, my monitor had a Detailed Resolution out of the box in CRU listed as 1920x1080@60hz with the polarity +/+ while my custom resolution for 1920x1080@70hz that works defaulted to +/-, does that mean anything?

Thanks for any help in advance, I know I asked alot here and I can imagine Toasty gets lots of questions each day so I appreciate any helping hand

EDIT: A small update, I decided to update my drivers to the newest leaked Catalyst Beta and obviously had to redo the whole CRU process, however this time I picked LCD Reduced for 71 and 75hz and 75hz now shows up and seems to work fine! Although my monitors OSD seems to display something strange now, the input signal is shown as: 1080p/1400x1050 75hz HDMI1
The actual displayed resolution still seems to be 1920x1080 though from what I can depict on screen and Windows itself says so aswell o.o Should I maybe open a separate thread?

EDIT 2: Seems like 75hz is a no-go for me, it works fine but causes my idle GPU clock to rise to 500mhz and my idle memory clock to 1375mhz o.o along with a temperature rise to 50°C so I will stick to 70hz for now I guess

EDIT 3: Upon further reading seems like this is normal and happens when the blanking? is too low so I won't mess with it further by myself since I have no idea what I'm doing with CRU other than changing the refresh rate
