16 GB DDR4-2666 ECC RDIMM for servers

This 16 GB registered DIMM runs at DDR4-2666 with CL19 latency and 1.20 V operation. It uses a 2Rx8 organisation and major-brand chips on a 288-pin module. The memory is built for server and workstation platforms that require error-correcting registered memory.

Verify DDR4 RDIMM support and slot availability

Confirm that your system accepts DDR4 registered ECC DIMMs at 2666 MT/s and has a free 288-pin slot. Check the qualified vendor list or manual for 2Rx8 population rules and maximum per-channel capacity. The module is a direct replacement for the listed Hynix part numbers.

Suits admins expanding ECC capacity on validated

Ideal for administrators adding reliable ECC capacity to compatible servers or workstations. Not suited for desktop boards that only accept unbuffered non-ECC memory. Buyers who need higher densities, different speeds or unregistered modules should look elsewhere.

商品問答

Does the single 16GB DDR4 2666 ECC RDIMM ship alone or with extra parts?

The module arrives as a single 288‑pin DIMM; no cables, brackets or additional memory sticks are included.

I see several Hynix part numbers listed — which one does this A-Tech module replace?

It is a compatible equivalent for HMA82GR7AFR8N-VK, HMA82GR7CJR8N-VK, HMA82GR7DJR8N-VK, HMA82GR7JJR8N-VK and HMA82GR7MFR8N-VK.

What does the 2666 MT/s rating mean once the stick is installed in a server?

The memory runs at 2666 MT/s with CL19 latency at the standard 1.20 V DDR4 voltage, delivering PC4‑21300 bandwidth in a registered ECC configuration.
