RE: vista don't recongize 4 gigs of system memory

Same here. I'm using 4gb of 667mhz ram in my xps m1210. Vista Ultimate
64bit Edition only see's 3326. Mobo verifies 4 though. This is a let down..

Hi John,

It's because there is a 4GB limit on the available addresses. Some of these
are reserved for the system's addresses, the remainder (what you see) is
what is available for memory addressing. This is a limitation in the 32-bit
system. You should not see this in the 64-bit version unless either a module
is bad or the mainboard is not reporting correctly (or doesn't support it).
