System-Specific 64 GB DDR5 Kit

This 64 GB kit contains four 16 GB DDR5 UDIMMs built for THINKMATE SB Grid-Standard workstations. Each module runs at 4800 MT/s with CL40 latency at 1.1 V. The unbuffered, non-ECC design matches the platform's standard memory slots. IT professionals select this kit for validated compatibility in mission-critical environments.

288-Pin Unbuffered Layout

The modules use a standard 288-pin DDR5 UDIMM form factor without heat spreaders, so they fit densely populated workstation boards. Unbuffered signalling keeps the electrical path direct for the supported platform. Major OEM Samsung, Micron or Hynix chips are used throughout. Installation follows the system manual and requires no special tools.

DDR5 4800 CL40 Specification

The decisive specification is DDR5 4800 with CL40 timing at 1.1 V in a 1Rx8 organisation. This exact speed, latency, voltage and rank configuration must match the workstation's qualified memory list. Builders needing ECC, registered modules, a different data rate or a different capacity per module cannot use this kit.

Questions about this item

What speed does the DDR5 4800 interface actually run at in this kit?

The kit operates at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V across all four modules.

Will these 288-pin UDIMMs fit the DIMM slots on my Thinkmate SB Grid-Standard workstation?

Yes, each 16 GB module is a standard 288-pin DDR5 UDIMM designed for the Thinkmate SB Grid-Standard platform.

Do I need to enable anything in the BIOS to get the full 64 GB recognised after installing the four sticks?

Install one module per channel, seat each stick until the retention clips click, then power on; the system will detect all 64 GB automatically at DDR5 4800.
