Help: HD3870 appears as X1900, won't do DX10

[ToTTenTranz]

I bought a Sapphire HD3870. In this system I've had a X1900XT and later an 8800GT.
After uninstalling the nVidia drivers, I inserted the HD3870, installed the latest 8.1 drivers and the driver identified my graphics card as a X1900.

I uninstalled the drivers, ran DriverCleaner for everything ATI related, erased everything I found about ATI in the registry, reinstalled the drivers and it still identifies as a X1900..

In Vista's System Information it identifies as a HD3870, the core clock is at 777Mhz (which is the default value for HD3870) and the performance is typical of a HD3870.

The only problem is that the games won't recognize it as a DX10 gpu so I can't run DX10 features in Crysis, Gears of War or UT3.


Any suggestion on how to solve this?

So.. Am I the only one in the world with this problem?

YUP:D The only thing I would do at this point is **FORMAT** I know, I know, people hate hearing that, but sometimes it is needed, especially since you have had 2 other types of video cards in your system. Format bro, all your issues will be solved.

That would be Xtremely unpleasant..

I'm in the middle of a 8800GT vs HD3870 review and I've already done the 8800GT's half of benchmarks, and that's actually the only reason I'm still using this system anyway...

C'mon, any way to change some registry setting or something?
I just don't have the time to do a double format+clean install ATM...

I had this exact same problem with my x1900xtx -> x2900xt upgrade.

DrivercleanerPro-> Hosed system
Image restore-> same problem
manual Registry nuder-> Hosed system

End result-> format system


Sorry :-/

or reinstall windows

What I would do...
Ati software unsinstall utility. Drivercleaner out any nvidia drivers. Reinstall DirectX 10. Reinstall ATI driver (I like 7.11, the newest is the devil IMO).

Last night I went berserk and manually deleted all ATI-related files that were in my O.S. drive. I did this after uninstalling the drivers, running drivercleaner on safe mode and erasing everything ATI-related in the registry. Even had to download a program that would grant me ownership for system-protected files and folders.
Still no luck. Installing the drivers would tell me again that I have a X1900 :(
I only tried installing the 8.1s.. should I try with 7.11/7.12?
How do I reinstall DX10 on Vista? Is that possible?

You could always do the obvious, and go into device manager and manually update the driver. Go through the steps, but choosing to do everything yourself. Then from the list, try and find the 3870 driver.
If it's not there, I'll say format is the only way.

Too late, I alrdeady formatted.. Thanks anyway. I think I actually did that during one of the 9999 times I tried to get the driver to work correctly..

It's such a stupid thing I don't know how the Catalyst driver team has let this through.. How can they give the same driver ID to cards that have completely different bioses and GPU IDs?
