A-Tech 4GB DDR3L 1600MHz ECC UDIMM 2Rx8 1.35V Server Memory

SKU CH-K6Z6-TFZ1A

4GB DDR3L 1600MHz ECC UDIMM 2Rx8 1.35V server memory module with Micron chipset for reliable performance

  • Total capacity4 GB
  • Rated speedDDR3L 1600 (PC3L 12800)
  • ChipsetMicron Chipset
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeUnbuffered
  • ECC protection guards data integrity in server workloads
  • DDR3L 1600 MHz speed matches PC3L-12800 system specs
  • Low 1.35 V voltage cuts power draw versus standard DDR3
  • 2Rx8 dual-rank layout maximises density per DIMM slot
  • 240-pin UDIMM form factor fits compatible server motherboards

Target system upgrade

This 4GB DDR3L module replaces the Micron MT18KSF51272AZ-1G6K1ZE in server and workstation platforms. It delivers ECC error correction and unbuffered operation for data integrity in always-on environments.

ECC unbuffered DDR3L at 1.35V

The stick runs at 1600MHz (PC3L-12800) with CL11 latency and a 2Rx8 organisation. Low-voltage DDR3L reduces power draw while maintaining compatibility with slots that accept 1.35V DDR3 memory.

240-pin DIMM for single-slot expansion

The module fits a standard 240-pin DDR3 DIMM socket and requires a platform that supports ECC unbuffered DDR3L at 1.35V. It adds capacity without registered buffering, leaving additional slots free for further upgrades.

Questions about this item

What does the 1600MHz speed mean when the module is installed in a server?

The module runs at DDR3L 1600 (PC3L 12800) with CL11 latency, delivering that bandwidth when the platform supports the 1600 MT/s data rate.

How does the DDR3L 1.35V interface affect compatibility with standard DDR3 slots?

It fits 240-pin DDR3 DIMM slots and operates at 1.35 V; the board must support DDR3L low-voltage operation for the module to run at its rated speed.

What physical clearance does the 240-pin UDIMM need inside a chassis?

Standard 240-pin UDIMM height; ensure the motherboard DIMM slots accept unbuffered ECC modules and that no heatsink or cable obstructs the full insertion depth.
