Capacity and Kit

This kit provides 64GB of DDR4 memory across two 32GB modules for dual-channel operation. It is intended for workstations, servers and NAS systems that require error-correcting code support. The modules run at 3200MHz with a CL22 latency at 1.2V.

Build Fit

The 288-pin unbuffered ECC UDIMMs install in standard desktop DDR4 slots and operate at the JEDEC 1.2V baseline. Backward compatibility covers 2133MHz, 2400MHz, 2666MHz and 2933MHz platforms. No heat spreader is fitted, so clearance around adjacent components is not increased.

Headroom and Limits

The 64GB capacity suits heavy multitasking, large datasets and virtualisation workloads. ECC protects data integrity in always-on server and NAS roles. Speed tops out at 3200MHz; systems that demand higher frequencies or registered modules will need different memory.

Questions sur cet article

How much capacity does the 2RX8 ECC unbuffered kit provide for sustained workloads?

The kit delivers 64GB total from two 32GB modules, giving workstations and NAS systems the headroom to keep large datasets in memory without swapping.

What is the operating voltage and thermal profile of these DDR4 3200MHz CL22 modules during all-day operation?

Each DIMM runs at 1.2V with no heat spreader, so power draw and heat output stay low even under continuous load in servers or workstations.

Which motherboard slot and memory standard must the system already support for this 288-pin UDIMM kit to function?

The platform needs DDR4 288-pin UDIMM slots that accept ECC unbuffered memory; the modules are backward compatible with 2133, 2400, 2666 and 2933MHz speeds.
