128GB DDR5 4800 Kit for Thinkmate Workstations

This 128GB kit contains four 32GB DDR5 4800 unbuffered UDIMMs built for Thinkmate SB Grid-Standard workstations. Each module runs at 1.1V with CL40 timings and a 2Rx8 organisation. The 288-pin DDR5 form factor fits the workstation's memory slots directly.

Suitable for Thinkmate upgrades.

The kit targets administrators expanding a compatible Thinkmate workstation to 128GB using non-ECC unbuffered modules. It is not for systems that require ECC error correction, registered DIMMs, or a different DDR generation. Buyers needing those features must select a matching memory type.

128GB total capacity in four 32GB modules

The single specification that decides fitment is the 128GB capacity delivered as four 32GB DDR5 4800 UDIMMs. Verify the workstation accepts 32GB non-ECC unbuffered modules per slot and supports the 4800 MT/s speed before ordering.

Questions about this item

Does my motherboard need DDR5 slots for this 128GB kit of 288-pin UDIMMs?

Yes, these modules use the 288-pin DDR5 UDIMM form factor and require a motherboard with DDR5 memory sockets.

Can I run these CL40 4800MHz modules alongside slower DDR5 sticks already in my system?

The kit runs at DDR5 4800 with CL40 timing; the motherboard will typically clock all installed DDR5 to the speed of the slowest module.

How do I confirm the full 128GB is recognised at 4800MHz after installing the four 32GB modules?

Check the BIOS memory information or the operating system task manager to verify 128GB total capacity and a reported speed of 4800MHz.
