Server-grade DDR5 RDIMM kit

This XPG AICORE kit delivers 64 GB of registered DDR5 memory across two 32 GB modules. It runs at 7200 MT/s with CL34 timings and includes on-die ECC plus side-band ECC for data integrity. A register clock driver and 30 µ gold-plated connectors help maintain signal quality under load.

Suited for registered-memory platforms

Designed for servers and workstations that require registered DDR5 DIMMs with ECC. The 1.40 V operating voltage and dual-channel layout support high-throughput workloads. Systems that accept only unbuffered UDIMMs or that cannot supply 1.40 V will not be compatible with this kit.

64 GB capacity for multi-threaded workloads

Two 32 GB modules provide ample headroom for virtualisation, database caching and large dataset processing. The 7200 MT/s transfer rate and tight 34-46-46 timings keep latency low while the registered buffer reduces electrical load on the memory controller. Applications needing more than 64 GB or higher frequencies will require additional modules or a faster kit.

Questions about this item

What motherboard slot and memory type are required to install these 288-Pin DDR5 RDIMMs?

The modules fit a 288-pin DDR5 RDIMM socket and run at 1.40 V, so the board must provide a registered DDR5 slot with that voltage.

Will the on-die ECC and side-band ECC on these 7200 CL34 modules still function if I mix them with slower registered DIMMs?

The kit operates at DDR5 7200 with timings 34-46-46; mixing speeds forces all DIMMs to the lowest common rate, but ECC remains active on each module.

How can I confirm the Register Clock Driver and temperature sensor are working after I seat the 64 GB dual-channel kit?

Check the BIOS memory report for 7200 MT/s speed, CL34 latency and registered status, then run a memory stress test to verify error correction and thermal monitoring.
