8GB DDR4 ECC UDIMM for Servers

This 8GB DDR4 2133MHz ECC unbuffered DIMM is built for server and workstation systems that require error-correcting memory. It operates at CL15 latency and 1.20V standard voltage. The module uses a 2Rx8 rank configuration with major brand chipsets. It serves as a compatible replacement for the Kingston KVR21E15D8/8 part number.

288-Pin DIMM with Major Brand Chipsets

The module uses a standard 288-pin DDR4 DIMM form factor for broad motherboard compatibility in server platforms. Unbuffered design suits systems that do not support registered memory. Major brand chipsets and rigorous quality assurance testing aim to deliver dependable, reliable performance. Buyers who need registered or load-reduced DIMMs cannot use this unbuffered module.

CL15 2133MHz Speed Decides Fit

The single specification that determines compatibility is the DDR4 2133MHz (PC4-17000) speed with CL15 timing. Your system must support this exact speed and latency combination for the module to function correctly. Verify your platform's qualified vendor list before purchase. Systems requiring faster DDR4 speeds or different CAS latencies will not match this module.

Questions about this item

What DDR4 speed and PC4 rating does this 8 GB ECC UDIMM run at?

The module operates at DDR4 2133 MHz with a PC4-17000 data rate.

Which DIMM pin count and form factor does this stick use?

It is a 288-pin DDR4 DIMM designed for standard server and workstation memory slots.

How do I install this ECC UDIMM and what is the common mistake to avoid?

Align the notch with the slot key, press firmly until both retention clips click, and ensure the system supports ECC unbuffered memory; the frequent error is mixing ECC with non-ECC modules.
