Green Samsung DDR3 server memory module 240-pin DIMM

SAMSUNG

SAMSUNG M393B5673EH1-CF8_UA DDR3 2GB 1066MHz 240-Pin ECC Registered DIMM accessory

SKU CH-22Q7-AHCZN MPN M393B5673EH1-CF8_UA

2GB DDR3 ECC registered server DIMM running at 1066MHz with CL7 latency and 1.35V operation

  • ECC protection prevents data errors in critical workloads
  • Registered design improves signal integrity for stable server operation
  • Low 1.35 V voltage reduces power draw and heat output
  • CL7 latency at 1066 MHz delivers responsive memory performance
  • 240-pin DIMM form factor fits compatible server motherboards

Server ECC Memory Module

This Samsung DDR3 module provides 2GB of registered ECC memory for server platforms that require error correction and signal buffering. The 240-pin DIMM operates at 1066MHz with a CL7 latency timing and runs at a low 1.35V voltage level. It is designed for systems that specifically support registered memory architecture.

Build Integration Requirements

The module fits a standard 240-pin DDR3 socket but demands a motherboard chipset capable of driving registered ECC DIMMs; consumer desktop boards will not initialise it. Its single-rank 2Rx8 organisation leaves additional memory channels free for further capacity expansion. No cables, brackets or software drivers are required for installation.

Thermals and Power Profile

At 1.35V the DIMM draws minimal power compared to standard 1.5V DDR3 parts, reducing strain on the memory voltage regulator. Passive cooling via case airflow is sufficient; no active heatsink or dedicated fan is needed. The registered buffer adds negligible latency while improving signal integrity across fully populated channels.

Highlights

  • ECC protection prevents data errors in critical workloads
  • Registered design improves signal integrity for stable server operation
  • Low 1.35 V voltage reduces power draw and heat output
  • CL7 latency at 1066 MHz delivers responsive memory performance
  • 240-pin DIMM form factor fits compatible server motherboards

Questions about this item

How does the 1.35 V voltage affect sustained use in a server?

The 1.35 V DDR3 module draws less power than standard 1.5 V parts, reducing heat output during continuous operation.

What noise or thermal load does the registered DIMM add when running all day?

As a passive component it produces no noise; the lower 1.35 V helps keep system temperatures down under constant load.

Which motherboard slot and chipset must I already have for this 240‑pin ECC registered stick?

You need a DDR3 server board with a 240‑pin DIMM slot that supports ECC registered memory at 1066 MHz PC3‑8500.
