I have 8Gb of RAM in 4 DIMM's on each system.
First PC:
RAM: 8Gb, 4 x 2Gb Corsair PC2-6400 modules
CPU: Intel C2Q 2.4GHz
M/B: ASUS Commando (iP965)
Video: nVidia 6800GS
Second PC:
RAM: 8Gb, 4 x 2Gb PC2-6400 Patriot modules
CPU: Intel C2D 2.4GHz
M/B: Gigabyte GA-G33-DS3R (iG33)
Video: int.
On both computers I get similar results - for example, on second PC:

Thanks to all for replies!
At this time I can't do more research on this problem, but at weekend I have
a lot time for testing and get one more PC with i975X chipset. So, after
Sunday I'll post results of testing x64 versions of FreeBSD 7.0/8.0, Ubuntu
Linux and OpenBSD on my three PC's with 8Gb RAM.
Regards,
Alexandr.
