Beware of thinking that you can use "any" memory just because the board is a bit less _picky_ about what un-registered modules will work. My module didn't work any better, yet I've found non-reg modules that worked just fine. But I've bought half a gig of registered memory now, so it's no biggie :-)
Anyway, there was a problem with Kingston using two types of chips on the same part number memory, one worked, the other didn't. Now Kingston are trying to figure out why, and in the meantime anyone who buys Kingston (recommended part number, I don't remember it now) and find themselves with Toshiba chips can just have Kingston send them another module. Kingston are really nice when it comes to support, I must say...
