ATI Radeon 64 DDR Problems

[Orgymang]

I've posted this in about 20 million forums by now. In all my games it puts these grid of white/grey dots in the background accept for on Quake 3 (if I have it in 32 bit depth). If it is put to 16 the dots will appear again. I have an Athlon TBird 1 Ghz on an ABIT KT7 with 256 megs of pc133 ram running Windows ME.

I had the same problem, and so I returned the board and got a new one (which fixed all problems). Check to see if the card gives the same problem in other computers - mine's did.

Ha! Are you sure that's not an unemployment line your seeing all those white dots in? I saw a couple of whites in line the last time I collected! No, but seriously, try reinstallin the chipset drivers for your mobo again, and DX 7 or 7.0a. If the drivers don't work, contact ATI for RMA, what your describing doesn't sound good.

There is a conflict between the "Gart" file for the VIA chipset on the KT7 and the Gart file for the ATI 64 DDR video card. ATI technical support advise users to change the "atigart.exe" filename (in the ATI directory) after installation to "atigart.ati" and then load the VIA AGP driver. This prevents a conflict between the two GART drivers.

The latest 4.13.7075 driver set are known to be stable with this board. I have also been informed that the recent 7078 beta drivers work well.

One user also reported that there is a sequence you need to follow in loading the board drivers and VIA's AGP driver. He recommended the following:

Fully remove the previous ATI driver set using uninstall.
Choose PCI Adapter and reboot.
Load DirectX 7.0a or 8 - reboot
Load latest VIA AGP driver - reboot
Load ATI driver set - reboot
Reload latest VIA AGP driver - reboot
Reload DirectX - reboot
You may need to set the AGP driving strength to 68.

Disabling P2C/C2P Concurrency in the Advanced Chipset Features menu of the BIOS instabilities solves a few of teh problems
