16 GB DDR4 ECC RDIMM for servers

This 16 GB DDR4 2933 MT/s module is a 2Rx8 registered DIMM with ECC and a CL21 latency. It runs at 1.2 V on a 288-pin interface and is built from major OEM chips for Hynix-compatible platforms.

Suited for ECC server upgrades.

The module targets IT professionals upgrading Hynix-compatible servers or workstations that require registered ECC memory. Systems that accept only unbuffered non-ECC DIMMs cannot use this stick.

Verify registered ECC support and slot count

Before ordering, confirm the motherboard supports DDR4 registered ECC RDIMMs at 2933 MT/s and has a free 288-pin slot. Check the system manual for maximum capacity per slot and population rules.

Questions about this item

Does my server motherboard need a 288-pin DDR4 RDIMM slot to accept this 16GB module?

Yes, this module uses the 288-pin DDR4 RDIMM form factor and requires a compatible registered DIMM slot on the motherboard.

Can I mix this 2Rx8 CL21 registered ECC module with existing 1Rx8 unbuffered DIMMs in the same system?

No, registered ECC RDIMMs cannot be mixed with unbuffered UDIMMs; the memory controller requires all installed modules to share the same registered architecture.

How do I confirm the module is running at 2933 MT/s with CL21 timings after installation?

Enter the system BIOS or use a hardware information utility to verify the detected speed shows 2933 MT/s and the CAS latency reads CL21.
