16GB DDR4 3200 ECC Registered DIMM

This 16GB DDR4 3200 module is built for servers and workstations that require error-correcting registered memory. It operates at 1.20V with CL22 latency and a dual-rank 2Rx8 organisation. The 288-pin form factor fits standard DDR4 DIMM slots in compatible platforms.

Suited for ECC registered memory channels

Buyers who need unbuffered UDIMMs or non-ECC memory for consumer desktop boards should look elsewhere. Systems that only accept single-rank modules or speeds above 3200 MT/s cannot use this part. Capacity per slot is fixed at 16GB.

Registered ECC with dual-rank layout

The Registered ECC design with 2Rx8 ranking is the single specification that determines compatibility. Only motherboards and CPUs qualified for registered ECC DDR4 3200 will accept this module.

Questions about this item

How do I install the 288-Pin DDR4 module and which notch alignment mistake should I avoid?

Align the single off-centre notch on the 288-Pin DDR4 module with the key in the server DIMM slot, press straight down until both side clips click, and do not force it backwards — the notch position prevents reverse insertion.

What maintenance or replacement will the registered ECC memory need over its service life?

No periodic maintenance is required; the module has no moving parts or batteries, so replacement is only needed if a memory test reports uncorrectable ECC errors or the server fails to recognise the 16GB capacity at POST.

At what point does the CL22 latency at 1.20V become the limiting factor during sustained workloads?

The CL22 timing at 1.20V is the first fixed limit encountered; the registered buffer adds one cycle, so sustained throughput cannot exceed the DDR4 3200 transfer rate defined by that latency and voltage combination.
