I bought P3200 ddr 400 1gb memory and when i install it , it does not show up. any ideas why and if there is something i can do .

The Intel® Server Board S875WP1-E supports both ECC and Non ECC Unbuffered PC2100 (266 MHz), PC2700 (333 MHz), or PC3200 (400 MHz) compliant Double Data Rate (DDR) memory modules. Dual channel memory functionality requires two DIMM modules installed into DIMM sockets 1A & 1B, and then DIMM sockets 2A & 2B. The DIMM module size, speed and vendor must be the same.

You can install a single 128 MB memory module into DIMM socket 1A. The minimum supported memory size is 128 MB. The minimum main memory configuration is a single 128 MB memory module, and the maximum configurable memory size is 4GB. With only a single memory module installed, the system will only operate using a one memory channel.

Third party memory vendors may use the same module part number with different
DRAM vendors and die revisions. To insure proper system operation, verify that each DRAM
vendor and die revision has been separately tested and qualified. Please notify CMTL if there is a discrepancy.

Can I increase the RAM from 504 to 1008 on my D310m/845G?

Yes you can increase the RAM of your motherboard. It contains two DIMM slots, but can only be upgraded to a maximum of 2-GB ( max of 1GB on each slot.) The slots support DDR Synch Dram PC2100 (266-MHz) and DDR Synch Dram PC1600 (200-MHz) Non-ECC Memory only.

    Slot 1
    Slot 2
    Each memory slot can hold DDR PC2700,DDR PC3200 with a maximum of 1GB per slot.*
    *Not to exceed manufacturer supported memory.
    • 184-pin DIMM Banking: 2 (2 banks of 1)
    • Chipset: Intel 845D
    • Error Detection Support: ECC and non-ECC
    • Graphics Support: AGP 4X
    • Max Component Density: 512Mb
    • Max Unbuffered DDR SDRAM: 2048MB
    • Module Types Supported: Unbuffered only
    • Supported DRAM Types: DDR SDRAM only
    • USB Support: 1.x Compliant
    Q: What memory goes into my computer, and will a faster speed be backward-compatible?
    A: DDR memory with support for DDR PC2700,DDR PC3200 speeds.
    Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds.
    Q: How much memory can my computer handle?
    A: 2048MB.
    Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.
    Q: Do I have to install matching pairs?
    A: No.
    No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance.
    Q: Does my computer support dual-channel memory?
    A: No.
    Your system does not support dual channel.
    Q: Does my computer support ECC memory?
    A: Yes.
    Your system supports ECC. You can put non-ECC modules into an ECC system, but be sure not to mix ECC and non-ECC modules within a system. Install the same type of modules that are already in your system.

    You may need to install memory in matching pairs. If the new memory is a single 1Gb module and you didn't already have a similar one they may not work together. Try removing the original module(s) and see if it makes a difference.

    2 x 1GB Samsung PC2100 appearing as just 1GB (2 X 512MB)

    Hi Patrick,
    I see you're point. I know this, you can not run "more than" 512MB in any DIMM slot. That is shown at the bottom of page 10 & the top of page 11. You can not run both types of memory at the same time, even though the chart looks like you could. The description term on page 10, states; Users only can install either 168-pin SDRAM Module or 184-pin DDR DRAM Module at one time. (You can't run both). You can run 4x512MB in all banks using184-pin DDR SDRAM. Or you can run 4x512MB in all banks of 168-pin SDRAMs. Total of 2GB.
    So you can not run 1GB of memory in any bank.
