Capacity & Configuration

This kit provides 512GB of DDR4 memory arranged as sixteen 32GB modules. It is built for ThinkMate STX-NL-QE24 E3 nearline storage servers that require registered ECC RDIMMs for stable operation under heavy workloads.

Registered ECC Requirement

The single specification that decides fitment is the registered ECC RDIMM form factor with 2Rx8 organisation and CL22 timing at 3200MT/s. Only systems designed for DDR4 registered ECC modules can accept this kit; unbuffered or non-ECC platforms will not function with these parts.

Thermals & Power Draw

Modules run at 1.2V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering adds minimal latency while keeping power draw low per module, so total consumption scales linearly with the sixteen-module population in a fully loaded chassis.

Questions about this item

What does 3200 MT/s mean once the modules are installed?

The kit runs at 3200 MT/s DDR4, delivering PC4-25600 bandwidth when the server memory controller operates at that speed.

How does the 288-pin RDIMM interface limit real-world use?

The 288-pin registered DIMM slot is required; the registered buffer adds one cycle of latency but allows the 16-module, 512 GB configuration to operate at 1.20 V.

What physical space and power does the 16-module kit need?

Sixteen 288-pin RDIMM slots and a 1.20 V supply are required; the modules have no heat spreader, so standard server airflow is sufficient.
