Server-grade memory kit

This NEMIX RAM kit provides 512GB of DDR4 3200 ECC registered memory across eight 64GB modules. It is built for THINKMATE TWX-QS8-14E3 and TWX-QS8-24E3 tower servers that require registered DIMMs with error correction. The 4Rx4 organisation and 1.20V operation match the platform's specifications.

Sustained-load behaviour

Registered buffering and ECC protect data integrity during continuous multi-threaded workloads such as virtualisation, database hosting or render farms. CL22 latency at 3200 MT/s delivers stable throughput without the voltage headroom that consumer modules rely on for short bursts.

Upgrade context

The kit replaces smaller-capacity DDR4 RDIMM sets when the server's memory controller supports 64GB 4Rx4 modules across all eight slots. It is not suited for systems limited to 32GB per slot, for platforms requiring unbuffered UDIMMs, or for any DDR5-only motherboard.

Questions about this item

How much power does the 1.2V DDR4 3200 kit draw when the server runs continuously?

Each module operates at 1.2V, the standard voltage for DDR4 3200, so total power scales with the eight 64GB sticks installed.

What must the ThinkMate TWX-QS8-14E3 or TWX-QS8-24E3 already have for this 512GB kit to work?

The tower server needs eight free 288-pin DDR4 RDIMM slots and a BIOS that supports 4Rx4 registered ECC modules at 3200 MT/s.

Can the CL22 4Rx4 modules share channels with older dual-rank RDIMMs I keep in the same chassis?

Mixing ranks and latencies on the same channel is not recommended; the platform will downclock all DIMMs to the slowest common settings.
