Today I found out that I have a motherboard that is 64bit capable, but lacks 64bit GPU drivers.
The motherboard is a DN2800MT. After installing 7x64 I was surprised not seeing unidentified hardware (that's a first for me with Windows), however, I noticed straight away that Windows was using the build-in GPU drivers. Those are so basic that even Patience starts complaining about the lack of graphics performance.
Not long after that I found out that Intel refuses to make 64 bit GPU drivers for this motherboard, while there are 64bit chipset, LAN and sound-drivers available. So why make those and not GPU drivers?
Then I found someone on this forum who linked to a beta driver (GFX_Vista_Win7_64_8.15.8.1050_Beta5.exe) that supposedly supports this particular GPU. Well.... after running the driverinstaller and a reboot, I got a BSOD. Another reboot -> BSOD. Safe-mode -> delete GPU driver -> no more BSOD, but crappy graphics performance due to the standard Windows driver being used again.
After a second attempt, not using the driverinstaller but let the device manager install the driver, it seems to run without problems, didn't get BSOD's anymore. Now I haven't tested much, Windows starts, graphics performance increased and Patience is no longer nagging about crappy graphics, gonna try more tomorrow.
Why are you (Intel) still refusing to make a GPU driver for this motherboard for any OS besides 7x86? This motherboard can run 7x64 without problems. The only thing that's a problem is the lack of GPU drivers. And no, I am not gonna switch to 7x86 because the full amount of RAM is not usable in 32 bits OS's.
