AMD chipset 690G is most likely broken.
It does not support 64bit DMA under any mainstream OS. It does not work in real 64bit mode under Vista nor Linux. Windows XP PRO 64bit uses 32bit DMA.
All independent reports tell the same story, no indipendent users get their 690G systems to work with 64bit DMA. Vendors, on the other hand, digg their trenches claiming they cannot reproduce the issues, or that they have never heard of it before.
Based on a thread posted on anandtech forums, I have compiled the hardware used in systems reported not to work. More will be added, as I plan to test one or two more boards.

There is nothing wrong with the hardware used, and the components are of high quality, not the one usually connected with incompability and instability.
The workarounds for Intel based systems does not help anything.
No patching works.
If you read user reviews posted on sites like Newegg, or search forums, you will find that the problem is widespread, but there is no fix.
Please note that AMD has not responded, even though I have been in direct contact with them.
If you know of a fix, or a working 690G system using 64bit DMA, please let me know. I know first hand of many that do not work, but none that does.

No vendor that I am aware of, have published a bios to fix the 64bit DMA issue.
The MBs used had updated BIOS.
There is no memoryremapping setting for any 690G board, as far as I know. I have not found this for any Asus, MSI, or Gigabyte board.

Catalyst 7.2-7.10 fails.

OS and patches

Vista Ultimate 64bit Norwegian and Vista Home Premium 64bit used.
KB929777 v1 or v2 does not work.
Linux kernel developers reports that even if the chipset reports 64bit DMA for AHCI, it produces all sorts of IO errors in 64bit mode. Future kernels will force 32bit DMA.

Hacks

Lowering RAM speed does not help.
Increasing RAM voltage does not help.
Easy RAM timings does not help any.
Using MSconfig and limiting memory to 4096MB or less, forcing 32bit DMA under 64bit Vista works. A max of 3.3GB RAM available using this hack.
