Server Memory Identity

This Samsung MR18R1628AF0-CM8 module is a 256MB 184-pin DDR SDRAM rated at PC 800 with ECC and unbuffered operation. It targets administrators maintaining legacy servers or workstations that require registered-free error-correcting memory. The heat spreader aids thermal management in dense chassis. Builders needing larger capacities or newer DDR generations must look elsewhere.

Thermals Noise Power

The integrated heat spreader dissipates heat across the module surface during normal server workloads. No active cooling is present, so system airflow must handle the thermal load. ECC operation adds minimal latency overhead while protecting data integrity. Power draw follows standard DDR PC 800 specifications for unbuffered modules.

Build And Connectors

The 184-pin edge connector fits legacy DDR DIMM slots keyed for PC 800 signalling. Unbuffered design allows direct connection to the memory controller without register delay. Heat spreader adds mechanical rigidity and protects ICs during handling. Installers should verify motherboard support for unbuffered ECC DDR before deployment.

Questions about this item

How do I install the 184-pin DDR module in my server?

Align the notch on the 184-pin DDR stick with the slot key, press firmly until both side clips snap shut, then verify the server POST recognises the full 256 MB.

What maintenance will this ECC unbuffered memory need?

No scheduled maintenance is required; if a correctable error count rises or the module fails POST, replace the stick with an identical PC 800 ECC unbuffered unit.

What limit appears first under sustained load?

The 256 MB capacity ceiling is reached before bandwidth or thermal limits on the PC 800 interface.
