We've got a development/test server running Windows server 2003 64bit, standard edition with SP2. (it also has dual boot to the 32bit edition)
How can I diagnose problems with memory? I'm worried we've got a faulty stick of RAM, but I want to check I haven't just missed a config setting somewhere before I get on the phone to Crucial.
The RAM's been upgraded to 4gb but windows (64bit) doesn't seem to be recognising the full 4gb. Task manager reports "3406152 kb" and system properties "3.25 gb".
Even more confusingly the BIOS reports only 2gb.
Extra Info: The hardware is basically a cheap desktop. It's got a Pentium 4 ("ACPI\GENUINEINTEL_-_EM64T_FAMILY_15_MODEL_4_0") in a Foxconn 945G7MA-8EKRS2 (intel 945G).
It's been years since I tinkered with hardware, and never in a 64bit or server OS, so I'm out of my depth.
