THINKMATE Server DDR5 RDIMM

This 64GB DDR5 4800 ECC registered DIMM is built for THINKMATE Supermicro SuperServer 611C-TN4R and 621C-TN12R platforms. It targets administrators who need single-module capacity upgrades in validated enterprise environments.

ECC Registered Stability

The module uses major OEM Samsung, Micron or Hynix chips in a 2Rx4 layout with on-die ECC and register buffering. This combination corrects single-bit errors and reduces electrical load on the memory controller, preserving data integrity under sustained server workloads.

64GB Single-Module Headroom

One 288-pin RDIMM delivers 64GB at 4800 MT/s CL40 and 1.1V, letting a compatible chassis reach high total memory with fewer populated slots. Systems requiring more than 64GB per channel or speeds above PC5-38400 will need additional modules or a faster platform.

Questions about this item

Will the 2Rx4 rank configuration require any firmware updates or module replacements down the line?

The 2Rx4 registered ECC module is a standard DDR5 4800 part with no moving components; it does not need firmware updates and has no scheduled replacement interval.

What limit appears first when the module runs at 4800 MT/s continuously in a 611C-TN4R or 621C-TN12R chassis?

The CL40 latency at 1.1 V is the primary electrical limit; thermal throttling only occurs if chassis airflow falls below the server vendor's specified minimum.

How much extra heat and power does a single 64 GB stick add when the server runs all day?

At 1.1 V the module draws roughly 12 W typical; it has no heat spreader, so it relies on the system's DIMM-slot airflow to stay within JEDEC thermal limits.
