Server-grade ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR4-3200 registered DIMMs built with ECC for error correction in mission-critical workloads. The modules run at 1.2 V with a CAS latency of CL22 and use a 2Rx8 organisation. They are validated for ThinkMate GPU-optimised servers including the GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU platforms.

288-pin registered form factor

Each stick fits a standard 288-pin DDR4 RDIMM slot and requires a motherboard that supports registered ECC memory. The lack of a heat spreader keeps the profile low for dense multi-socket chassis. Registered buffering reduces electrical load on the memory controller, allowing larger total capacities in compatible ThinkMate systems.

Replaces non-ECC or slower DDR4

Upgrading from unbuffered non-ECC modules adds single-bit error correction and multi-bit detection for data integrity. Moving from lower-speed DDR4 to PC4-25600 raises peak bandwidth for GPU-accelerated compute. The jump is worthwhile when the server motherboard and BIOS explicitly support registered ECC at 3200 MT/s.

Questions about this item

What does the DDR4 3200 PC4-25600 interface cap at in practice?

The DDR4 3200 PC4-25600 interface runs at up to 3200 MT/s, delivering 25600 MB/s peak bandwidth per module.

What physical slot and clearance does this 288-pin RDIMM kit need?

It requires two DDR4 288-pin RDIMM slots; the modules have no heat spreader, so they fit under standard server CPU coolers.

How are these registered ECC modules installed, and what step is often missed?

Align the notch with the key, press firmly until both retention clips click, then enable ECC in the BIOS to activate error correction.
