SKU CH-7V5Q-ZCW4E

An 8 GB DDR3L 1600 CL11 ECC registered RDIMM for Supermicro X9DBU, X9DR3, X9DR7, X9DRD and X9DRE motherboards

  • Total capacity8 GB
  • Rated speedDDR3L 1600 (PC3L 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered
  • Memory rank1Rx4

Capacity 8GB

  • ECC registered design prevents data corruption in servers
  • 8GB single module expands capacity for X9 series boards
  • DDR3L 1600 CL11 speed matches system specifications
  • 35V low-voltage operation reduces power draw
  • 240-pin RDIMM form factor fits Supermicro X9DBU X9DR3 X9DR7 X9DRD X9DRE

Server ECC RDIMM Upgrade

This 8GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35V operation. It is a registered ECC DIMM built for workstation and server platforms. The single-rank 1Rx4 design fits 240-pin slots in compatible Supermicro X9 series motherboards.

Workstation and Server Builders

Suits administrators extending the life of Supermicro X9DBU, X9DR3, X9DR7, X9DRD or X9DRE systems. Not for standard desktop PCs or consumer laptops that require unbuffered non-ECC memory. Builders needing unregistered modules or different voltage specs should look elsewhere.

Direct Replacement Module

Replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16. No heat spreader is included, relying on chassis airflow for cooling. The JEDEC-compliant, RoHS-compliant stick arrives as a single DIMM ready for installation.

Questions about this item

Which Supermicro motherboard series must I already have for this 240-pin DDR3L 1600 RDIMM to be compatible?

This module is validated for Supermicro X9DBU, X9DR3, X9DR7, X9DRD and X9DRE series motherboards.

Can I keep my existing unbuffered DDR3L DIMMs and add this ECC registered 1Rx4 module alongside them?

No, registered memory cannot be mixed with unbuffered memory; all slots must use registered ECC modules.

How do I confirm the module is running at PC3L-12800 CL11 1.35 V after installation?

Check the BIOS memory information or use a system utility such as dmidecode to verify speed, latency and voltage.
