Server DDR4 ECC UDIMM kit

This A-Tech kit provides 8 GB of DDR4 ECC unbuffered memory in two 4 GB modules. It is built for servers and workstations that require error-correcting code RAM and will not work in standard desktop or laptop computers.

Single-rank 1Rx8 organisation

Each module uses a 1Rx8 single-rank layout with CL15 latency at 2133 MHz. The rank configuration is the critical specification that determines whether your server’s memory controller can populate all slots at the rated speed.

Standard-voltage thermal profile

The modules run at the DDR4 standard 1.2 V, keeping power draw and heat output low in typical server workloads. Unbuffered ECC DIMMs of this density operate quietly with passive cooling in properly ventilated chassis.

Perguntas sobre este artigo

What does 2133 MHz mean once this kit is installed in a server?

The modules run at DDR4-2133 with CL15 timing, giving each 4 GB stick a peak transfer rate of PC4-17000 for faster data access in compatible systems.

How does the ECC UDIMM interface limit what this memory can do?

ECC UDIMM adds single-bit error correction without buffering, so it works only in servers and workstations that support unbuffered ECC — not in standard desktops or laptops.

What physical slot and clearance does this 288-pin DIMM need?

Each stick fits a standard DDR4 288-pin DIMM socket at 1.2 V; verify your board’s channel layout and heatsink clearance before seating both modules.
