768 GB DDR5 ECC RDIMM kit

This kit provides 768 GB of DDR5 ECC registered memory across twelve 64 GB modules. It is built for Thinkmate RAX-QE12 rackmount servers that require registered DIMMs with error correction. The modules run at 4800 MT/s with a CAS latency of 40 at 1.1 V. Buyers upgrading compatible Thinkmate platforms can install the full kit to reach the maximum supported capacity.

Verify registered DIMM support and slot count

Before ordering, confirm that the target server accepts 288-pin DDR5 RDIMMs and has at least twelve available memory slots. The modules are 2Rx4 registered parts; unbuffered or non-ECC slots will not work. Check the system documentation for qualified memory configurations and any population rules that apply to large-capacity kits. The kit is validated for the Thinkmate RAX-QE12 platform.

Standard voltage and passive cooling

Each module operates at 1.10 V with no heat spreader, relying on chassis airflow for cooling. Registered DDR5 modules at this voltage typically draw modest power per DIMM, and the lack of a spreader keeps the profile low for dense rackmount layouts. Acoustic output depends on the server fans rather than the memory itself. Ensure the system provides adequate airflow across all twelve slots.
