32 GB DDR5 kit for Thinkmate TWX-QS4-14R7

This 32 GB kit contains two 16 GB DDR5 4800 UDIMM modules built for the Thinkmate TWX-QS4-14R7 tower server. It targets administrators who need a straightforward capacity increase without ECC overhead. The modules arrive new and are validated for that specific platform.

Unbuffered non-ECC design

Each stick uses a 1Rx8 organisation at 1.10 V and carries no heat spreader, keeping the profile low for dense server chassis. The 288-pin DDR5 interface fits the board’s native slots directly, so installation follows the usual DIMM seating procedure. Non-ECC unbuffered operation means the memory controller handles error detection, which suits workloads that tolerate standard reliability.

CL40 latency at DDR5 4800 decides fit

The kit runs at PC5-38400 with a CAS latency of 40, a timing set by the platform’s memory controller. If the server’s qualified vendor list calls for CL40 at 4800 MT/s, this part matches; if the system requires lower latency or registered ECC modules, this kit will not meet the spec.

Questions about this item

What does the DDR5 4800 PC5-38400 rating mean for real-world bandwidth?

Each module runs at 4800 MT/s with a PC5-38400 designation, providing 38400 MB/s theoretical bandwidth per stick in dual-channel configuration.

Will these 288-pin UDIMMs fit the memory slots in a ThinkMate TWX-QS4-14R7 tower server?

Yes, the 288-pin DDR5 UDIMM form factor matches the DIMM slots on the ThinkMate TWX-QS4-14R7, and the kit is validated for that platform.

What is the correct seating procedure for these non-ECC unbuffered modules, and what step is most often missed?

Align the notch with the slot key, press straight down until both side clips click shut, then verify the clips are fully locked; the missed step is checking both clips.
