Server DDR3L ECC UDIMM

This 8 GB DDR3L module runs at 1333 MHz with CL9 latency and 1.35 V operation. It uses an unbuffered ECC design in a 2Rx8 configuration built with major-brand chips. The 240-pin DIMM targets servers and workstations that require error-correcting memory.

Compatibility check

Verify that your system accepts DDR3L 1333 MHz ECC UDIMM modules before ordering. Confirm the motherboard supports 1.35 V low-voltage operation and unbuffered ECC memory. Cross-reference the Samsung part numbers M391B1G73AH0-YH9 and M391B1G73BH0-YH9 for exact replacement guidance.

Build and daily use

Major-brand chips and rigorous testing deliver dependable performance in continuous server workloads. The standard 240-pin DIMM connector fits compatible slots without adapters. Low-voltage operation reduces heat output in densely populated memory banks.

Questions about this item

What is included with the 8GB DDR3L 1333 ECC UDIMM and what must I source separately?

The package contains one 8GB DDR3L 1333 ECC UDIMM module rated at 1.35V with 2Rx8 organisation; any additional modules or a compatible server motherboard with 240-pin slots must be obtained separately.

How do I decide between the Samsung M391B1G73AH0-YH9 and M391B1G73BH0-YH9 part numbers this module replaces?

Both Samsung part numbers share the same 8GB capacity, DDR3L 1333 speed, ECC UDIMM type and 1.35V voltage, so this single A-Tech module serves as a direct replacement for either variant.

What does the 1333 MHz rating mean once the module is installed in a server?

The module operates at DDR3L 1333 (PC3L-10600) with CL9 latency at 1.35V, delivering ECC-protected throughput up to that bus speed when the platform's memory controller runs at the matching frequency.
