  • Low 1.20 V voltage cuts power draw and heat output
  • Validated compatibility with listed ASRock, Gigabyte, Intel and Supermicro platforms

8 GB DDR4 2133 ECC DIMM

This 8 GB DDR4 module runs at 2133 MHz with CL15 timings and 1.20 V operation. It provides ECC error correction in an unbuffered 288‑pin DIMM format. The dual‑rank 2Rx8 organisation suits workstations and entry‑level servers that require data integrity. Kingston ValueRAM branding indicates standard validated reliability.

Suited for ECC unbuffered DDR4 platforms

Buyers needing registered or load‑reduced modules cannot use this stick. Systems limited to non‑ECC memory will not benefit from the error‑correction feature. Builds requiring capacities above 8 GB per slot or speeds beyond 2133 MHz should select different modules.

Unbuffered ECC with CL15 at 2133 MHz

The combination of unbuffered signalling and on‑die ECC is the decisive attribute for motherboard compatibility. Only boards that explicitly support unbuffered ECC DDR4 at 2133 MHz will POST correctly with this part. Verify the platform memory qualification list before ordering.

Questions about this item

What does the 2133 MHz speed mean once this module is installed in a server?

The module runs at 2133 MHz, delivering up to PC4 17000 bandwidth for workloads that can use that throughput.

How does the 288-pin DDR4 interface limit performance in practice?

The 288-pin DDR4 connection caps transfer rate at 2133 MHz, so faster CPUs or chipsets cannot push this memory beyond that speed.

What physical space does the 288-pin DIMM need to fit in a chassis?

It requires a standard 288-pin DDR4 DIMM slot and enough vertical clearance for a module without a heat spreader.
