A-Tech 16GB (4x4GB) DDR3 1333 ECC UDIMM 2Rx8 1.5V server RAM

Server DDR3 ECC UDIMM kit

This 16 GB kit contains four 4 GB unbuffered ECC modules built for DDR3 servers and workstations. It runs at 1333 MHz with a CL9 latency at the standard 1.5 V. The dual-rank x8 organisation suits multi-channel server boards that require error-correcting memory. Desktop and laptop systems cannot use these modules.

16 GB quad-channel capacity

Four modules populate a quad-channel controller for maximum bandwidth on supported platforms. The 16 GB total handles typical virtualisation workloads, database caches and multi-user application servers. Capacity runs out when large in-memory datasets or heavy container densities exceed the installed amount. Additional kits can be added if the motherboard provides more DIMM slots.

240-pin unbuffered build quality

Each module uses major-brand chips on a 240-pin DIMM PCB tested to A-Tech standards. Unbuffered ECC design means the memory controller talks directly to the DRAM without a register, so signal integrity depends on clean board layout and proper seating. The quad-channel kit simplifies population order — install one module per channel for balanced throughput.
