Certified server memory

This 32GB DDR4 3200 RDIMM is Supermicro certified and uses Hynix chips. It delivers ECC registered operation at 1.20V with CL22 latency. The module is built for servers and workstations that require validated, registered memory. It installs in a standard 288-pin DDR4 slot.

Suited for qualified platforms

It fits administrators upgrading or repairing Supermicro systems that specify this exact part number. Buyers who need unbuffered UDIMMs, non-ECC memory, or a different speed grade should look at other modules. The dual-rank 2Rx8 organisation must match the platform's memory population rules.

Deciding specification

The registered ECC RDIMM form factor with 2Rx8 organisation determines whether this module works in a given system. Only platforms that support registered ECC DDR4 at 3200MHz with this rank configuration will accept it. Verify the motherboard or server manual before purchasing.

Questions about this item

What is included with the MEM-DR432L-HL04-ER32 and what must be purchased separately?

The box contains one 32GB DDR4 3200 ECC RDIMM module. Additional modules must be bought separately if your server requires more than 32GB or a matched pair.

How do I decide between the listed versions or capacities for this module?

This SKU is a single 32GB dual-rank 2Rx8 stick at 3200MHz CL22. Choose it when your board supports 32GB per slot and you need registered ECC; select a different capacity SKU if your system limits DIMM size.

What does the 3200MHz rating mean once the RDIMM is installed in a server?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V. Actual throughput depends on the CPU memory controller and the number of populated channels.
