Compatible DDR5 Kit

This 64 GB kit contains two 32 GB DDR5 modules built for Thinkmate SB Grid-Standard workstations. The sticks run at 4800 MT/s with a CL40 latency and operate at 1.10 V. They are non-ECC unbuffered UDIMMs using a 288-pin layout.

Workstation Upgrade Path

The kit suits IT professionals upgrading compatible Thinkmate systems with matching DDR5 slots. Buyers who need ECC error correction or registered modules should look elsewhere. Systems requiring different pin counts or voltage levels cannot use these sticks.

2Rx8 Rank Configuration

Each module uses a dual-rank 2Rx8 organisation with major OEM chips from Samsung, Micron or Hynix. The rank structure determines how the memory controller addresses the chips and must match the platform specification for stable operation.
