I've got a GA-P35-DS3R (rev 1.0) and 2x1GB Patriot 800MHz PC2-6400 memory. I get data corruption while copying files, only when the memory is in dual-channel mode. In single-channel mode everything appears to be fine.
The memory passes memtest+, even in dual channel mode.
Memory specs are here: Patriot Memory - Products
(Although my sticks are marked 2.2V, not 2.1V as shown on the website.)
System specs are
CPU: Q6600 (G0 stepping) 2.4GHz
Mobo: Gigabyte P35-DS3R (rev 1.0) [F13d]
RAM: 2x1GB Patriot 800MHz PC2-6400
PSU: Corsair VX450W
Video: Gigabyte GeForce 8600GT
HD: Samsung HD501LJ
OS: Win XP Pro sp2
Flashing to the latest BIOS didn't help. I've tried dimm voltage up to 2.2V and MCH up to +0.2V with no improvement. I tried running the memory at 667MHz with no improvement.
I haven't had any luck setting memory timings manually. When I tried setting DRAM Timing Selectable to Manual and entering what I thought were very relaxed timings, the computer wouldn't boot at all and I had to clear the CMOS. I was trying to use the loosest settings from this post: http://forums.tweaktown.com/f69/memo...vs-bios-27283/
The same thing happened when I set Timing to Manual but left all of the individual timings on Auto.
Here are the current BIOS settings:
Robust Graphics Booster___________ [Auto]
CPU Clock Ratio _________________ [9]
CPU Host Clock Control_____________[Disabled]

What else should I try? Or is a bad board or RAM? Or are they not compatible for some reason?
