8GB DDR3L 1600 ECC RDIMM Server Memory

This A-Tech module delivers 8GB of registered ECC memory for server and workstation platforms that require DDR3L 1600 operation. The single-rank 1Rx4 design uses major-brand chips at 1.35V low voltage. It serves as a direct replacement for several Samsung part numbers listed in the specifications.

DDR3L 1600 Registered DIMM Limits

The DDR3L 1600 standard tops out at PC3L-12800 bandwidth with a CL11 latency profile on a 240-pin interface. Registered buffering adds a clock cycle for command addressing, which stabilises large-capacity configurations but prevents use in consumer boards that accept only unbuffered modules. Voltage is fixed at 1.35V; the module will not negotiate higher DDR3 voltages.

Compatibility Checks Before Ordering

Verify that your system expressly supports DDR3L registered ECC DIMMs at 1600 MHz and accepts 1Rx4 rank organisation. Confirm the motherboard or server manual lists 1.35V operation and 240-pin RDIMM slots. This module will not function in platforms limited to unbuffered non-ECC memory or those requiring a different DDR generation.

Questions about this item

Which A-Tech 8GB DDR3L ECC RDIMM should I select if my server requires a 1Rx4 registered module at 1.35V?

This single 8GB stick is a 1Rx4 registered DIMM running at DDR3L 1600 with 1.35V, matching the Samsung M393B1G70BH0-YK0 and related part numbers listed.

What does the DDR3L 1600 (PC3L-12800) rating mean once the module is installed?

It indicates a 1600 MT/s data rate at 1.35V low voltage with CL11 timing, delivering the standard PC3L-12800 bandwidth for registered ECC server platforms.

How does the 240-pin DDR3L RDIMM interface limit what the module can do in practice?

The 240-pin registered DIMM form factor fits DDR3L server slots only; the registered buffer and ECC require a compatible chipset, and the 1.35V operation excludes standard 1.5V DDR3 slots.
