Dual Channel borked?!

Hello,
alright, this story is quite complicated, and only has partially to do with overclocking. I'll try and sum it up as much as possible.

Basically, I moved to England from Canada a couple months ago, brought my computer with me except the psu/case. Rebuilt it here, and since then have had mad problems getting things working like they used to. I used to be running at 3.5 ghz, 290 fsb with a 3:2 divider on my PC3500 Mushkin Dual Channel kit (see comp specs in sig). Since I've gotten here, I've had a lot of problems with spontaneous rebooting of my machine. I know it's not a heat issue, or a video card issue, and now that I have a new OCZ Powerstream 520W, I know it's not a power issue.

The rebooting gets worse as I overclock more and is accompanied by general instability (Prime 95 crashes after 3 mins at 3.5), even though at 290 fsb, the RAM is actually running slower than at 200 fsb (388 vs 400) because of the divider. I think I've managed to finally isolate the problem. It seems like when I run my RAM in single channel, the problems go away. I didn't do extensive testing with this, but basically, in dual channel, at 290 fsb, I get a crash within 3 minutes of Prime 95, in single channel, it ran for an hour before I turned it off with no errors. WTF?! These are the exact same components that were running fine for a year in Canada. How would dual channel suddenly not work properly. Could a bent capacitor or some other form of physical damage from transport on the motherboard somehow cause this?

Please help, this problem has been driving me insane since I got here.

Thanks, Adrian
 
Huh? What are you talking about? This is some high quality stuff. It's BH-5 chips that can do 2-5-2-2. Unfortunately, they don't overclock too well so I'm stuck at a 3:2 divider.

Anyway, I don't see how in the hell RAM could ever get damaged during transport, cause like I said everything was working great for a year before I came here.

I checked the RAM to make sure it wasn't one of the sticks' fault. Both of them individually are solid at 3.5 ghz, and also together in single channel. But in dual channel everything is screwy.

Well, of course it could be the RAM, I have no idea, I just don't see how it could have been damaged during transport
