64 GB DDR5 ECC RDIMM kit for Thinkmate servers

This 64 GB kit contains two 32 GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for Thinkmate Supermicro SuperServer 111C-NR, 121C-TN2R and 121C-TN10R platforms that require registered error-correcting memory.

Capacity and headroom for virtualisation workloads

Two 32 GB modules give 64 GB total, suited to multi-VM hosts and database buffers. The 1Rx4 organisation and 4800 MT/s rate feed many cores, but the single kit leaves no spare slots on two-channel boards if the platform only provides two DIMM sockets per channel.

Registered DDR5 build with 288-pin interface

Modules run at 1.10 V without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor fits only registered DDR5 slots; it will not work in unbuffered desktop boards or earlier DDR generations.

Questions about this item

Will the 4800 MHz DDR5 RDIMMs run with existing DDR5 4800 modules already in my ThinkMate server?

Yes, both kits operate at DDR5 4800 (PC5-38400) with CL40 latency and 1.1 V, so the new 2 x 32 GB modules will match the speed, timing and voltage of identical DDR5 RDIMMs already installed.

How can I confirm the ECC registered memory is active after installation?

Enter the system BIOS or UEFI on the ThinkMate 111C-NR, 121C-TN2R or 121C-TN10R and verify that 64 GB total is reported with ECC enabled and registered mode shown for each 288-pin slot.

What comes in the box and do I need extra parts?

The package contains two 32 GB DDR5 4800 CL40 ECC RDIMM modules (part MR38400-314K2); no heat spreaders, cables or additional hardware are included or required for installation in the compatible ThinkMate Supermicro SuperServer models.
