32GB DDR4 2133 ECC LRDIMM for Supermicro Servers

This 32GB DDR4 2133 ECC LRDIMM is built for Supermicro servers that require load-reduced memory. The module runs at PC4-17000 with CL15 latency and operates at 1.20V. It targets administrators expanding capacity in qualified Supermicro platforms.

288-pin LRDIMM installs in qualified Supermicro

The 288-pin LRDIMM seats in standard DDR4 server slots on Supermicro motherboards that list MEM-DR432L-HL01-LR21 in their qualified vendor list. Systems that do not support 4Rx4 load-reduced modules will not post with this DIMM installed. Verify the platform QVL before fitting.

32GB single module with 4Rx4 organisation

One module delivers 32GB of ECC capacity using a 4Rx4 Hynix chipset. The quad-rank layout maximises density per slot but reduces the number of modules the memory controller can address. Workloads needing more than the platform's maximum supported load-reduced capacity will require a different configuration.

Questions about this item

How can I confirm the module is running at 2133 MHz with CL15 after installation?

Check the memory speed and CAS latency in your server BIOS or a hardware monitoring tool; they should report DDR4 2133 (PC4-17000) and CL15 at 1.20 V.

What exactly is included — just the 32 GB LRDIMM or any extra parts?

The package contains one 32 GB Hynix HMA84GL7MMR4N-TF 4Rx4 LRDIMM (288-pin); no cables, brackets or additional modules are supplied.

Should I choose the 4Rx4 quad-rank LRDIMM or a dual-rank alternative for my Supermicro system?

Select this 4Rx4 LRDIMM (MEM-DR432L-HL01-LR21) only if your Supermicro motherboard qualified-vendor list specifies a quad-rank load-reduced module; otherwise a dual-rank DIMM may be required.
