Good memory tester for Vista

[Drum Thumper]

Well if it bluescreens during the test then is it safe to assume that it's the memory that's the problem?

If you run the memtest on the UBCD, it will start throwing errors if there's a RAM issue. Bear in mind, there is a possibility that it very well may not be the RAM, it could be the board itself. I've seen it in the past--someone tried to shove DDR2 RAM in a DDR slot and said slots throw errors left and right. Thankfully for this person, the other two slots on the board work.

You can download an ISO of memtest86+ from http://www.memtest.org/
It also they appear to have an installable version for windows as well.

Good software.

++ for Memtest86. If none of the sticks throw errors when tested individually, make sure you have the timing set to the slowest of the group when they are all in at the same time.
