SuperMicro ML23400-944K1 64GB DDR4 2933 ECC LRDIMM

This NEMIX RAM module provides 64GB of DDR4 2933 memory in a single 288-pin load-reduced DIMM. It is built for SuperMicro server and workstation platforms that require ECC registered memory. The 4Rx4 organisation and 1.20V operating voltage follow the PC4-23400 specification. CAS latency is rated at CL21.

Suited for capacity upgrades in compatible

Administrators expanding memory in qualified SuperMicro servers will find this module matches the required DDR4 2933 ECC LRDIMM profile. Builders using consumer motherboards, non-ECC platforms or standard unbuffered DIMM slots cannot use this part. Systems limited to lower densities or different rank configurations should look elsewhere.

4Rx4 rank organisation governs slot population

The quad-rank x4 layout determines how many modules the memory controller can address per channel. If the target platform restricts total ranks per channel, this 4Rx4 module may reduce the maximum achievable capacity. Verify the system's rank-per-channel allowance before purchasing.

Questions about this item

Should I pick the 64 GB single module or look for a smaller kit?

The 64 GB module fills one 288-pin slot; add identical modules to reach the capacity your Supermicro board supports.

What does the 2933 MT/s rating deliver once installed?

It runs at 2933 MT/s (PC4-23400) with CL21 latency at 1.20 V, giving the rated bandwidth your platform negotiates.

How does the LRDIMM interface affect maximum capacity?

The 4Rx4 load-reduced design lowers electrical load on the memory bus, letting the Supermicro server populate more slots per channel.
