ThinkMate DDR5 4800 ECC RDIMM

This 16 GB registered DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It targets ThinkMate Supermicro SuperServer 521C-NR platforms that require ECC RDIMM memory for data-integrity workloads.

Installation notes

The 288-pin form factor seats in standard DDR5 RDIMM slots; the module is unbuffered for heat spreader clearance. Registered buffering adds one cycle of command delay, so the system BIOS must support registered DIMMs or the server will not post.

Suited for ThinkMate 521C-NR upgrades

Ideal for administrators expanding capacity in validated ThinkMate SuperServer 521C-NR configurations. Not suitable for desktop boards that accept only unbuffered non-ECC DDR5, nor for systems limited to lower densities or different pin counts.

Questions about this item

How can I confirm the module is running at 4800 MT/s and CL40 after installation?

Check the BIOS or a tool such as CPU-Z; the SPD will show DDR5 4800 (PC5-38400) with CAS latency 40 and voltage 1.10 V.

What does the package contain and is anything else required?

The box includes one 16 GB DDR5 4800 ECC RDIMM (part MR38400-618K1); no extra parts are needed for a compatible THINKMATE Supermicro SuperServer 521C-NR.

Which capacity or version should I choose for this server?

This listing is a single 16 GB 1Rx8 registered DIMM; select it when you need one 16 GB module for the 521C-NR.
