32GB DDR4 2666 UDIMM for Supermicro systems

This single 32GB DDR4 2666 module uses a 288-pin UDIMM form factor and runs at 1.20V with CL19 latency. It is built as a 2Rx8 non-ECC unbuffered DIMM validated for Supermicro platforms. The part number MD21300-328K1 identifies the specific configuration.

DDR4 2666 speed and unbuffered design

The DDR4 2666 PC4-21300 interface caps peak bandwidth at the JEDEC standard rate for this speed grade. Unbuffered operation means the module connects directly to the memory controller without a register, so the platform must support unbuffered DIMMs at this density. Non-ECC function provides no error correction for data integrity.

Check motherboard qualification

Verify that the Supermicro motherboard or workstation lists this part number or the equivalent SuperMicro MEM-DR432L-HL01-UN26 in its qualified vendor list. Confirm the system accepts 32GB unbuffered UDIMMs per slot and that a free 288-pin DDR4 slot is present. Mixed populations with registered or ECC modules are not supported.
