4GB DDR3L ECC UDIMM for servers

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It uses an unbuffered ECC design with 1Rx8 organisation on a 240-pin DIMM. The kit targets administrators upgrading Micron-based servers or workstations that require low-voltage error-correcting memory.

Direct replacement for Micron MT9KSF51272AZ parts

The module matches the Micron MT9KSF51272AZ-1G6E1 and MT9KSF51272AZ-1G6P1 part numbers using Micron chipset components. It delivers the same PC3L-12800 specification in a single 4GB stick. No additional accessories or software are bundled with the memory.

Verify DDR3L 1.35V support

Confirm your platform accepts DDR3L 1600MHz unbuffered ECC DIMMs at 1.35V before ordering. Check the maximum supported capacity per slot and total system limit in your server documentation. Systems requiring registered or fully buffered DIMMs cannot use this unbuffered module.

Questions about this item

Will the 1Rx8 ECC chips on this DDR3L module need replacement under normal server workloads?

The module uses Micron chipset components tested to A-Tech quality standards; ECC corrects single-bit errors in real time, so the chips themselves do not wear out and require no scheduled replacement.

What thermal limit appears first when this 1.35 V DDR3L UDIMM runs continuously at 1600 MHz?

The JEDEC-rated 1.35 V low-voltage operation keeps power draw low, so the module stays within its specified thermal envelope before any throttling or error-correction overhead becomes a bottleneck.

How much fan noise or extra heat does this 240-pin DDR3L ECC stick add when the server runs all day?

At 1.35 V the stick draws minimal power, adding negligible heat to the chassis; standard server airflow handles it without requiring higher fan speeds or audible noise increase.
