3GB mem problem

[Guest]

Situation is little bit strange. I have 3GB ram mem which works fine under
Win XP and Ubuntu, but after installation of Vista RC2 I can't boot that
system until I unplug one of 1GB sticks. I run Windows Memory Diagonostic
Tool and MemTest86 and both passed successful. I have KingstonValue RAM 2x
KVR400AK2 and 1x KVR400X64C3A on DFI Lanparty NFII Ultra-B. Thanks for any
help.

solution!!!! Can anybody else help

Not so strange if you get trouble with this, mixing single and dual channel
(KVR400AK2 (Dual) and 1x KVR400X64C3A (Single!)) doesn't work right!
It might have been working if the OS doesn't check well, but Vista tests the
memory much better and therefore is giving this kind of trouble.

I've seen this message, I think at the first time installing Vista.. said
"reserving 768 meg" for something....

I was uising 3 x1 GB PC3200 400Mhz from crucial, brand new all the same type
of moduals. I did crank the PC up after doing vista memory test, bit it
failed to reboot, now running with 2GB, can't use flash USB to bolster memory
either.

You should upgrade to RTM. There have been a number of fixes.
