Any G92 based cards should be ok, even 55nm versions, so thats:

8800GT
8800GTS-512
8800GS
9600GSO-384
9800GT
9800GTX
9800GTX+
9800GTX2
GTS150
GTX230
GTX240
GTX250

...did I miss any? :D

Nvidia re-branding is just getting silly now. :laugh:

working with 191.07, as with any drivers since 180.xx till now.

I think SLI with different GPU's don't work, there are much more checking , maybe on hardware level, that just DeviceID. I tried SLI with 8800GTX + 8800GTS 320 (both G80), reflashed BIOS from GTS to GTX, and no way in any case.

I think maybe 384bit + 320bit memory interface was the problem, so maybe these "GS" / "GSO" cards will not work either,

but all the other G92 cards have a 256bit memory interface so they should be ok, I know 128SP + 112SP / 96SP is ok,

and I think 256MB + 512MB has been allowed in the official drivers for a long time

?

Hi

If you are using HALmod you can use different drivers, so it works with 191.07 driver.

Use latest StringInstaller + Halmod v0.9 + Latest Drivers + Win7 x64.

Run all as "Run as admin"

Sorry for my ignorance aGeoM, but I'm looking for the files and I don't find them. I also need some guidance, if there are some instructions or something.

if it does do a hardware check on the dev level you might be able to fool it by flashing a new bios o the card and just changing the device name. i mean i know for sure it fools the drivers. me and plenty of other ppl have done it.

Hi Solaris

How can we change Device ID in VGA bios? I have done with nibitor but it doesn't change, only bios code, but not the device.

eg. Device change from 9800GT (0605) to GTS250 (0615), in this case the drivers will recognise an 9800GT, but if I open bios I see (0615) as Device ID.

I also did with RW Everything, but as soon it refresh the device Id goes to normal (0605)

hmm you might need to reinstall the driver after that happened to me once or twice and iv seen it happen to another forum member as well.
