64GB DDR4 3200 ECC RDIMM for ThinkMate towers

This 64GB registered DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It uses a 4Rx4 organisation and 288-pin form factor for ThinkMate TWX-QS8-14E3 and TWX-QS8-24E3 tower servers. ECC and registered buffering protect data integrity in mission-critical workloads.

Verify DDR4 RDIMM support and slot population rules

Confirm the server accepts DDR4 registered DIMMs and check the memory population guide for 4Rx4 modules. Ensure the BIOS is current and that the target slot supports 1.2V operation. Mixed-rank configurations may limit maximum speed or capacity per channel.

Replaces non-ECC or lower-capacity DDR4 RDIMMs

The upgrade adds ECC protection and 64GB density in a single module, reducing slot usage compared to smaller RDIMMs. It is worth the jump when workloads demand registered memory with error correction and the platform supports 4Rx4 organisation at 3200MHz.

  • 64GB single module expands server capacity
  • DDR4 3200 speed handles demanding workloads
  • ECC registered design protects data integrity
  • 2V operation reduces power consumption

Questions about this item

Does the single 64 GB module ship alone or with extra parts?

The package contains one 64 GB DDR4 3200 RDIMM and nothing else; no cables, brackets or tools are included.

How do I choose between the TWX-QS8-14E3 and TWX-QS8-24E3 tower servers for this memory?

Both tower models are listed as compatible; select the module that matches the server you already own or plan to buy.

What does the CL22 latency mean when the module runs at 3200 MT/s in a registered ECC configuration?

CL22 indicates 22 clock cycles of CAS latency at the rated 3200 MT/s speed; the registered buffer adds one cycle of command delay for signal integrity.
