Certified Server Memory for Supermicro Systems

This 16 GB DDR3L module is built for Supermicro servers and workstations that require registered ECC memory. It suits administrators upgrading or repairing validated platforms where data integrity and qualified hardware are mandatory. Buyers needing consumer desktop memory or non-ECC unbuffered DIMMs should choose a different product.

Registered ECC with 2Rx4 Organisation

The single specification that determines fit is the 2Rx4 registered ECC layout at DDR3L 1600 (PC3L 12800) with CL11 timing. Only systems qualified for this exact rank configuration and voltage will post reliably. The 240-pin RDIMM form factor prevents installation in UDIMM-only slots.

Low-Voltage Operation at 1.35 V

DDR3L 1.35 V reduces power draw and heat output compared with standard 1.5 V DDR3, helping dense server chassis stay within thermal limits. Registered buffering lightens the electrical load on the memory controller, contributing to stable operation under sustained workloads. No active cooling is required on the module itself.

Questions about this item

What does the 1600 MHz speed mean when this module runs in a server?

The module transfers data at 1600 MT/s, delivering PC3L-12800 bandwidth; the memory controller will negotiate the highest supported rate up to that ceiling.

How does the DDR3L 1.35 V standard limit power draw and compatibility?

DDR3L operates at 1.35 V instead of 1.5 V, reducing power per module; it is backward-compatible with 1.5 V slots but will only run at the lower voltage when the platform supports DDR3L.

Will the 240-pin RDIMM form factor fit my Supermicro motherboard?

Yes, the 240-pin registered DIMM matches the standard DDR3 RDIMM slot; verify your board accepts 2Rx4 registered modules before installing.
