I installed four gigabytes (4 x 1GB DIMMs) of RAM in my new system. BIOS and System Properties recognize all 4GB. The Performance tab in the Task Manager indicates that only 2GB of physical memory is available (see the attached screen shot). Performance is affected. Any thoughts on how/why this is occurring?
OS - Windows Server 2008 Datacenter Edition 64 bit *Note: this is used as a workstation and test server, not as a production server.
Motherboard - Gigabyte GA-EG41MF-S2H Rev. 1.0
Memory Model - NVIDIA PC2 8500 SLI Ready
Memory DIMMs - 4 DIMMs, 1GB each = 4GB
Troubleshooting Steps Taken:
-I swapped out the memory with replacement and it still only recognizes half of it.
-I tried rearranging the DIMMs in the slots. The problem persists.
What additional information should I obtain to identify the cause and/or find a solution?
