16 GB DDR4-2400 ECC Registered DIMM

This 16 GB module runs at DDR4-2400 with CL17 timing and 1.20 V operation. It is built for servers that require registered memory with error-correcting code support. The 288-pin form factor fits standard DDR4 DIMM slots in compatible platforms.

Straightforward DIMM installation

Align the notch on the 288-pin edge connector with the slot key and press firmly until the retention clips click. Registered modules add a small electrical load, so populate slots according to the system manual to avoid signal integrity issues. Mixing registered and unbuffered DIMMs will prevent the system from posting.

Verify registered ECC support

Confirm the motherboard or server platform explicitly supports DDR4 registered ECC memory before ordering. Some consumer chipsets accept only unbuffered non-ECC modules and will not recognise this DIMM. Check the qualified vendor list for 16 GB DDR4-2400 registered parts to ensure compatibility.

Questions about this item

How can I confirm the module is running at DDR4 2400 with CL17 after installation?

Check the BIOS or a system utility such as CPU-Z; it should report 2400 MT/s (PC4 19200) and CAS latency 17 for the 16 GB registered ECC DIMM.

What comes in the box and do I need any extra parts to install this 288-pin DDR4 module?

The package contains the 16 GB DDR4 2400 ECC registered DIMM only; no cables, brackets or additional components are required for a compatible server slot.

Which capacity and speed version should I choose for a server that takes 16 GB DDR4 2400 registered ECC memory?

This model 836220-B21-AX is the 16 GB DDR4 2400 CL17 1.20 V registered ECC variant; select it when your platform specifies those exact parameters.
