Default Machine Check Exception AMD64 nForce4

Hi, I have a problem getting Machine Check Exceptions about twice a week. They look like this (below) and they it causes a kernel panic.

HARDWARE ERROR
CPU 0: Machine Check Exception: 4 Bank 4: b200000000070f0f
TSC 1083628c0c94d

It seems that many other people have a similar problem:

Most people seem to blame it on the nforce4 chipset. Has anyone verified this?

My hardware:
AMD Athlon 64 3000+
MSI K8N Neo4-F
2-512MB Mushkin HP3200 DDR
Radeon X700 Saphire
320G Seagate HD SATA

I'm running gentoo with kernel 2.6.22-gentoo-r1. This problem has happened for all kernels that I've tried. I used to have a PATA drive and it seemed that when I upgraded to SATA drives the problem became much less frequent. I don't overclock and I have tested my memory and even tried replacing the dimms.

Of all the threads and forums I've found through searching, no one has found out the cause or a permanent solution to the problem. Has anyone in this forum had the same problem and/or found a good solution?
