System-Specific 256GB DDR4 Kit

This 256GB kit contains two 128GB DDR4 3200 registered ECC RDIMMs built for the Thinkmate XF4-24S3 workstation. It targets IT professionals and system builders who need maximum registered capacity in a validated configuration for memory-intensive server workloads.

Registered ECC 288-Pin Modules

Each module uses a 4Rx4 organisation with major OEM chips from Samsung, Micron or Hynix and runs at 1.20V with CL22 latency. The registered design and error-correcting code protect data integrity under sustained load, while the standard 288-pin form factor fits the workstation's DIMM slots without a heat spreader.

Two-Module 256GB Package

The box delivers a matched pair of 128GB sticks totalling 256GB, ready for dual-channel population in the qualified platform. Modules are stress-tested under load before shipping, giving administrators confidence that the upgrade will post cleanly and maintain stability in production environments.

Questions about this item

Does the DDR4 3200 interface cap real-world throughput at PC4-25600?

Yes, the kit runs at DDR4 3200 with a PC4-25600 data rate, so the theoretical peak bandwidth is capped at 25600 MB/s per module.

What physical slot and clearance does the 288-pin RDIMM need?

Each 128GB module uses a standard 288-pin DDR4 RDIMM form factor and has no heat spreader, so it fits any server DIMM slot with normal vertical clearance.

How is the 4Rx4 registered kit installed, and what step is often missed?

Power down, open the chassis, align the notch on each 288-pin RDIMM with the keyed slot, press firmly until both locking tabs click, then verify in BIOS that all 256GB are detected at 3200 MT/s.
