HELP: 6870 identified as 4870

[Funkstar De Lux]

Hi all,

I've just bought myself a new XFX 6870 Black Edition to try and get back into PC gaming. However, I am having terrible problems with my setup at the moment. I noticed that games were freezing every few seconds (like something is paging to disc), and generally running sluggishly. I then noticed that Tomb Raider Anniversary demo identified my card as a 4870! Surely this is the problem. It's identified as a 6800 series in Device Manager, but no where else. The Windows WDM drivers on Windows Update refuse to install.

I have used Driver Cleaner.Net and Driver Sweeper (and in safe mode too), and reinstalled the newest drivers loads of times now - nothing seems to work. Does anyone know what I can do to solve this? Or point me to another forum that would help me solve this?

My setup is the following:

ASUS 650I SLI
Intel Q6600
4GB DDR2 @ 800Mhz
XFX 6870 Black Edition
EMU 1820M Sound Card
2 Mechanical Drives

Welcome

What power supply do you have?

Did you go from Nvidia to AMD or not?

You might want to try a clean windows install as a last resort and install fresh drivers for everything you have in your rig.

I have a really good Coolermaster PSU, it's a 650W. I went from a 8500GT, 4870, then a 6870.

I can't reinstall windows because I have a very complex audio setup with I could rather not try to duplicate

Sounds like you might have todo a windows reinstall if the drivers are still thinking your on the old card.

Have you tried manually installing the new drivers?

 

[Funkstar De Lux]

Doing a fresh install isn't really solving the problem, it's just ignoring it. Tried manual install, still same problem occurs

[paradisiac]

have you tried driversweeper and then installed drivers?

 

[Funkstar De Lux]

Yeah, tried driver sweeper - same results.

 

[paradisiac]

will install Tomb Raider Anniversary demo and see what it thinks my 2xHD6850s are. is it easy to find the info, never played it?
what does CCC say it is?

 

[paradisiac]

mine says 6800 series so yeh, something is up

 

[Clav]

I know you don't want to reinstall Windows but that is really the only step left to take.

/edit on second thoughts you could install Ubuntu on a memory stick to confirm that your card is actually working fine as a 6870

 

[paradisiac]

what do things like 3dmark 11 say it is, and what score do you get?

 

[Emlyn_Dewar]

Ran driver sweeper you say? Bad times.

You should re-install Windows to remove the meddling that it will have done.

Really? Driver sweeper has saved me from a fresh windows install and all that goes with it on a few occasions when having issues post hardware changes.

 

[paradisiac]

never had an issue with driver sweeper either.

At this point a fresh install is the way forwards? Win 7 doesn't take long at all

Got another pciex16 slot? fit it into that.

Try > Right click my computer > manage > device manager > display adapters > right click your card and click "scan for hardware changes"

If those fail, reinstalling windows 7 only options,

Safe mode, uninstall drivers, reboot into safe mode again, device manager --> display adapters --> uninstall and tick "delete drivers" or similar.

Reboot into normal windows, put new ATi drivers on. Huzzah!

Note: If after uninstalling standard VGA drivers you can't boot into windows, simply reboot into safe mode again and reboot into normal mode - it's random if this happens or not it seems.
