Capacity and Configuration

This kit provides 256GB of DDR4 memory arranged as four 64GB modules. It is built for servers and workstations that require large memory footprints for virtualisation, database workloads or high-density compute tasks.

Registered ECC with 4Rx4 Organisation

Each module is a 288-pin RDIMM running at 3200 MT/s with CL22 latency at 1.2V. The 4Rx4 rank structure and registered buffer with ECC are the decisive attributes; the system memory controller must support this exact rank and buffering type for the kit to function.

Suited for ThinkMate QF4-14TP Workstations

This memory is validated for the ThinkMate QF4-14TP platform. Buyers who need a different capacity, a non-registered DIMM, or a module rank not listed here should look at other kits.

Questions about this item

What does the DDR4 3200 CL22 rating mean for throughput in my Thinkmate QF4-14TP?

The modules run at DDR4 3200 with CL22 latency, matching the workstation's supported memory speed for stable data transfer under load.

How does the PC4-25600 standard limit performance in this system?

PC4-25600 defines the 3200 MT/s data rate ceiling; the QF4-14TP memory controller will not exceed this rate regardless of module capability.

What physical slot and clearance do the 4Rx4 RDIMMs need in the QF4-14TP?

Each 64 GB stick uses a 288-pin DDR4 RDIMM form factor with no heat spreader, fitting standard server DIMM sockets in the workstation.
