32GB DDR4 ECC RDIMM for servers

This 32GB DDR4 2933MHz module is built for servers, workstations and NAS systems that require ECC registered memory. It uses a 288-pin RDIMM form factor with a 2Rx4 rank configuration and operates at 1.2V. The module is not compatible with standard desktop computers or unbuffered memory.

Capacity and headroom at 2933MHz

The single 32GB stick adds substantial capacity for virtualisation, large databases or memory-intensive workloads. It runs at PC4-23400 with CL21 latency and will down-clock to 2133MHz, 2400MHz or 2666MHz when the platform demands it. Systems needing more than 32GB per slot or higher frequencies than 2933MHz will need different modules.

DDR4 RDIMM interface limits

The DDR4 RDIMM standard tops out at 2933MHz in this configuration, so bandwidth is capped at PC4-23400 speeds. Registered signalling adds a clock cycle of latency compared with unbuffered DIMMs, which is normal for ECC server memory. The 288-pin keying prevents installation in desktop UDIMM slots, and the module cannot be mixed with non-ECC or unbuffered memory.

Questions sur cet article

Will this 2933MHz DDR4 RDIMM run stably alongside my existing 2133MHz or 2400MHz modules?

Yes, the module is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 speeds, so it will downclock to match the slower modules in the same channel.

How can I verify the ECC registered function is active after installing this 2Rx4 32GB stick?

Check the BIOS or UEFI memory information screen; it should report ECC enabled and show the module as registered with a 2Rx4 organisation at 2933MHz.

Does the 288-pin RDIMM come with a heat spreader or any extra accessories in the box?

The module has no heat spreader and ships as a single 32GB DDR4 ECC registered DIMM; no cables, brackets or additional components are included.
