Last night, I replaced two 512 MB DDR2 with two 1GB DDR2 chips, because one of the original chips failed a memory test. Before the replacement, my system registered 3062Mb RAM. After the replacement, Vista still reports exactly the same amount of RAM.
The motherboard in the Intel D945PSN, and the Operating System is Windows Vista Ultimate x86. I know because of 32bit addressing the OS won't see the full 4GB, but I expected at least a small increase in memory, to 3.5GB. Is there something extra I need to do to get Vista to recheck the installed RAM? Oh, and the system BIOS does recognize the new RAM, showing 2048x2. The new chips were specifically recommended for the mobo.
The only way to learn anything is to question everything.
