Server Memory Upgrade

This 4 GB DDR3 1333 MHz registered ECC module is built for server and workstation boards that require registered DIMMs. It replaces Samsung M393B5273BH1-CH9, M393B5273CH0-CH9, M393B5273DH0-CH9 and M393B5273EB0-CH9 parts. Buyers needing unbuffered UDIMMs or higher-density kits cannot use this module.

Thermals and Power

The stick runs at the standard DDR3 voltage of 1.5 V with CL9 latency, keeping power draw low inside a 240-pin DIMM slot. Passive cooling is sufficient for normal server workloads because registered buffering reduces electrical load on the memory controller. No active fan or heatsink is required for typical operation.

Compatibility Assurance

Each unit is tested against major-brand chipsets to verify reliable POST and sustained throughput in qualified platforms. The lifetime warranty and US-based technical support provide direct assistance if a compatibility issue arises during installation. Systems that do not support registered ECC memory will not accept this module.

Perguntas sobre este artigo

How do I install this 240-pin DDR3 ECC RDIMM, and what step is often missed?

Power off the server, open the chassis, align the notch on the module with the slot key, press firmly until both locking tabs click, then verify in BIOS that the 4GB module is recognised at 1333 MHz with ECC active.

What maintenance or replacement will this registered DIMM need over time?

No scheduled maintenance is required; keep the server's air filters clean so the 1.5 V modules stay cool, and replace the DIMM only if memory diagnostics report correctable or uncorrectable ECC errors.

What limit appears first when this 2Rx8 module runs under sustained load?

The memory controller's maximum supported capacity per channel or total system limit will be reached before the 1333 MHz CL9 rated speed becomes a bottleneck.
