I just installed the latest 13.1 driver from AMD for my ATI HD4870X2 GPU on a Win7 64-bit system. The first time I used the Catalyst control center the overdrive feature worked fine and I was able to see clock speeds, Temp, activity etc. But once I restarted my computer the overdrive feature doesn't work anymore. I don't even see the page for it.

Did anyone else have this problem?

This is after a clean install of Win7 64bit .Before I had Win Vista and it worked just fine.

These are my specs:

CPU - Intel Core 2 extreme X6800 @ 2.93Ghz
mobo - Asus P5W DH Deluxe
GPU - ATI HD4870X2
RAM - 8GB Corsair dominator
PSU - thermaltake 750W
monitor - 24" Dell 2407WFP

Uninstall 13.1 and try something older.

i tried 12.1 and it still didn't work

Try a clean install, there's a thread somewhere that describes how to do it, just use the search.

That would be in the FAQ section.

I think you should try a clean install of your graphics suite. Here is one way to do it > http://forums.amd.com/game/messageview.cfm?catid=444&threadid=162444&enterthread=y  pay special attention to the .netframeworks requirement for latest drivers and update if necessary before trying to install the new drivers.
 
Also, don't use the auto-install thing. Follow steps 1-4 and download drivers. http://support.amd.com/us/gpudownload/Pages/index.aspx

Unistalling all ati drivers/registry keys and changing Catalyst versions doesn't solve the issue, as i have the same problem with my 4870X2.

Just to be sure have you checked with Gpu-z to see if Crossfire is still enabled?, because it shows disabled for me.

I've opened a ticket a week ago and have been goin back and forward with support and we haven't found a solution yet.

It's just extremely annoying you can't see/adjust overdrive settings, my temp solution to being able to see Performance/Overdrive is TaskManager>close ccc + MoM and then right click catalyst in start and run as admin.

That sounds interesting. There may be a conflict with UAC somewhere. I wonder why people keep it on when it does cause more issues than gives protection.

I understand if you want it on, but for some testing, you could try disabling UAC completely and see if it solves the issue. If it does, you could set CCC.exe and MOM.exe to always start as admin if UAC is enabled. If it works, you have to tell this to AMD support, and they will see where to problem is.

The only way to properly do this is monitoring the install process and reverting every single thing the installer does to your system. Same for initial launch of any Catalyst component. If you're relying on some stupid driver sweeper application, it probably won't remove everything, especially .NET related stuff.

I think the problem started with this when they removed the key (unlock) on the Overdrive tab, because it's a just User Agreement now, non the less i forwarded the information.

Regarding unistalling all ati drivers/keys, i've done this atleast 100+ times over the years and never had any issues with reinstalling a new driver and getting it to work, this time it's not working correctly.

I've searched every registry and folder and the only 3 ati files that remain are controlsets Legacy_amdkmdag.

I'm going back and forward with support every other day with things that could be the problem, so far no solution.
