256GB DDR4 ECC RDIMM kit for Thinkmate QF4-14TP

This 256GB kit contains two 128GB registered DDR4 modules built for the Thinkmate QF4-14TP workstation. It delivers ECC error correction and registered signalling for stable operation in mission-critical server environments. The modules run at 3200MHz with a CL22 latency at 1.20V.

2x128GB 4Rx4 registered modules

The kit supplies a matched pair of 4Rx4 RDIMMs using major OEM DRAM from Samsung, Micron or Hynix. Registered buffering reduces electrical load on the memory controller, allowing high-density population. No heat spreaders are fitted, ensuring compatibility with dense server chassis airflow designs.

DDR4 3200 PC4-25600 288-pin ECC RDIMM specification

The single specification that decides fit is the DDR4 3200 PC4-25600 288-pin ECC RDIMM form factor with 4Rx4 organisation. Systems requiring unbuffered UDIMMs, different rank configurations, non-ECC memory or other DDR generations cannot use this kit.

Questions about this item

Will the 128 GB modules need active cooling or replacement fans over time?

No heat spreader is fitted, so the modules rely on chassis airflow; with adequate server cooling they require no extra fans or scheduled replacement.

What sustained-use limit appears first on these CL22 4Rx4 RDIMMs?

The registered buffer and quad-rank organisation add latency at CL22, so memory-controller throughput typically saturates before thermal or power limits.

How much noise, heat and power does the 256 GB kit draw at 1.20 V?

Each 128 GB RDIMM runs at 1.20 V with no onboard LEDs or fans, so acoustic output is zero and thermal load stays within standard DDR4 registered DIMM limits.
