Capacity and interface

This A-Tech module provides 8GB of DDR3L memory running at 1600 MHz with a PC3L-12800 rating. It uses a 240-pin UDIMM form factor, operates at 1.35V, and includes ECC error correction with an unbuffered design.

Who this suits and who it does not

Server and workstation owners needing a direct replacement for the listed Samsung part numbers will find this module compatible. Builders requiring registered or load-reduced DIMMs, or systems that only accept 1.5V DDR3, cannot use this unbuffered low-voltage kit.

Deciding specification

The 1.35V DDR3L voltage combined with ECC unbuffered operation determines whether this DIMM matches your platform. Verify that your motherboard specifically supports DDR3L ECC UDIMMs before ordering.

Questions about this item

What speed does the DDR3L 1600 interface actually run at?

The module operates at DDR3L 1600 MHz, also listed as PC3L-12800, with a CAS latency of CL11.

Will this 240-pin DIMM fit my server board?

It uses the standard 240-pin DDR3 DIMM form factor, so it fits any slot that accepts unbuffered DDR3 ECC UDIMMs.

How do I install the module and what step is often missed?

Align the notch on the 240-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that the system reports 1.35 V operation.
