64GB DDR4 ECC UDIMM kit for Thinkmate servers

This kit provides 64GB of DDR4 3200 memory in two 32GB modules. It is built for Thinkmate RAX-XS4-11E3 rackmount servers that require ECC unbuffered DIMMs. The modules run at 1.2V with a CAS latency of CL22.

Unbuffered ECC limits and DDR4 3200 ceiling

Unbuffered ECC memory works only on platforms that support ECC without registered buffers. The DDR4 3200 rating sets the maximum JEDEC speed; the system will not run this kit faster without overclocking. Capacity is fixed at 64GB across the two slots used.

288-pin UDIMM form factor and chip-level reliability

Each module uses a 288-pin UDIMM edge connector and 2Rx8 organisation with major OEM chips from Samsung, Micron or Hynix. No heat spreader is fitted, so airflow in the server chassis must cool the DRAM directly. The kit is validated for the listed Thinkmate platform.

Questions about this item

Should I pick the 64 GB kit or a 32 GB single module?

The kit supplies 64 GB total as two 32 GB modules; a single 32 GB module would provide only half that capacity and leave one channel unpopulated.

What does DDR4 3200 PC4-25600 mean for actual throughput?

The modules run at 3200 MT/s with a peak transfer rate of 25600 MB/s, delivering that bandwidth when the motherboard operates them at the rated speed.

How does the 288-pin ECC UDIMM interface limit what I can install?

The 288-pin unbuffered ECC UDIMM form factor fits only DDR4 slots that accept ECC unbuffered modules; it will not work in registered-only or non-ECC consumer boards.
