Directx 11 wrong display card information

Hello
I have a wired problem. and cant find a solution anywhere.

I had a Radeon HD 3870 x2 and changed it for HD 6970.

installed new drivers. but Directx 11 still shows i have "HD 3870 x2" in the display tab.
so no Directx 11 features in games.

I did a clean up with DriverCleaner in safe mod a couple of times. and re installed drivers. but no luck. it seems like a Directx problem.
(bdw the catalyst information is correct and showing HD 6900 series.)

when I install the driver again, the directx shows a correct 6900 display card,
But when i reboot it changes back to 3870 x2

my specs:
Windows 7 ultimate N
4 Gb ddr3
Radeon 6970
Asus P5KC

P.S
I really dont want to format.

thanks in advance!

You can't uninstall DirectX no matter what anyone or any site might indicate. It is a part of Win 7. What version of Catalyst are you using?

Catalyst 12-2

cant i manually change the Directx information regarding my graphic card?

or at least figure out why (or what file) is causing that miss information ?

Do a quick scan of your registry (via REGEDIT). See if you can find any hard entries listing your old GPU. If so, delete them.

Honestly, it sounds like your registry is possibly corrupted and the easiest "fix" would be a fresh install. Just something to keep in mind.

Well i did a scan and deleted the entries
until i got to:
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\PCI\VEN_1002&DEV_950F&SUBSYS_20421002&REV_00\6&3b56cc6b&0&00000008]

there i found 13 keys that cant be deleted due to and error: "Unable to delete all specified values"
there are also 2 sub-folders, one of them called "properties" which i cant even access
i get an Error:
"Properties cannot be opened. An error is preventing this key from being opened. Details:Access is denied."
the "regedit" was opened with Run as administrator

Try removing those entries while running in Safe Mode.

Hello everyone!

I have exactly the same problem as "sasbrzx" but with different hardware:

Motherboard: Gigabyte GA-MA785GMT-UD2H with an integrated Radeon HD 4200.
CPU: Athlon II x4 635
OS: Windows 7 64 bit

I recently upgraded my discrete GPU from a radeon x1950pro to Radeon HD 6850. I thought everything was fine untill I realised I was playing new games under Dx9 instead of Dx11.
I did a little of research and I discovered that although I have the newest drivers installed (catalyst 12-3), the system says I have installed the Radeon HD 4200!!! and that's the reason I can't play Dx11 titles (Radeon HD 4200 is only Dx10.1 compilant)

I have tried ccleaner, driver sweeper, reinstalling drivers, and no luck...

By the way, I have the integrated VGA disabled in the BIOS, so how is it possible that windows recognize this card??

There is something weird, cause when I plugged the 6850 for the first time windows didn't recongnized any new hardware, and nor does now everytime I remove and reinstall the new drivers...

I don't know what else to do!! I tried regedit too, but how do I know which are the possible wrong entries??

sasbrzx, any advance??

Please help!

Thank you!

Honestly, you are likely to have to reinstall Windows to completely resolve the matter. However, please take a look at the manual scrub of your registry while in Safe Mode. The worst thing that could happen is you would have to re-install. Good luck!

well, i finaly went into safe mod. (due to a power failure)
but still couldnt delete this reg keys,
then i found this method:

1. on key that gives you msg "error deleting key", add yourself with full control to permission, apply
2. go advanced, owner tab, check "replace owner on...", click OK, you'll get an error but just ignore it
3. refresh, that will give you access to subkey
4. now you'll be able to able to change permissions on the subkey and eventually delete the lowest subkey

so i went over all the registry and manualy changed anywhere there was: "HD 3870 X2" to "HD 6970"
-no errors occurred

and installed the latest catalyst: 12.4

so now i need to see if it still changing back after restarting.

I am restarting my machine so rarely that it seems like every time i do, AMD is out with a new driver version lol.

Hope this works :D

When you scrubbed your registry (manually), did you run a reg cleaner (like CCleaner) to remove any orphans?

Changing the text of a reg entry may not do the trick. You may have to delete those keys, then scrub the registry, then re-install the current drivers.

.....or, re-install Windows from scratch and have a nice fresh install to work from.

i did run CCleaner before(when i first noticed the problem) and it didnt solve the problam.
so this time i didnt run it.
what do yo u mean by "orphans" and "scrub"(clean?)

BDW i know a clean install of windows will solve the problem, im trying to avoid it. if it will come to that i will live it this way. it doesnt worth it.

Often when programs are uninstalled or updated, stuff gets left behind in the registry. Those are sometimes referred to as orphans. Scrubbing/cleaning is going through the registry and removing those entries.

CCleaner will identify for you after you delete any keys (like those associated with the Radeon keys).
