64GB DDR4 ECC RDIMM for Supermicro H11DSi

This 64GB DDR4 3200 CL22 registered ECC module is built for Supermicro motherboards H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN and H11SSL-C. It targets server and workstation operators who need maximum capacity per slot. Standard desktop systems cannot use registered memory.

Replaces Supermicro MEMDR4 part numbers

The module replaces Supermicro part numbers MEMDR464LCL02ER32, MEMDR464LCL03ER32, MEM-DR464L-CL05-ER32, MEMDR464LHL02ER32, MEMDR464LHL03ER32, MEMDR464LSL01ER32, MEMDR464LSL02ER32 and MEMDR464MCER32. The upgrade is worth it when your workload demands more than the current installed capacity and the board has free 288-pin slots.

Verify registered ECC support and slot count

Confirm the motherboard model is listed above and that the BIOS supports 64GB registered ECC DIMMs. Do not mix this module with unbuffered memory. Ensure enough 288-pin DDR4 slots are available for the desired total capacity.

Questions about this item

Will this 288-pin DDR4 RDIMM fit the DIMM slots on a Supermicro H11DSi motherboard?

Yes, the 64 GB module is a 288-pin DDR4 3200 CL22 ECC Registered DIMM validated for the H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN and H11SSL-C boards.

What is the correct installation sequence for this registered ECC module on a dual-socket H11DSi system?

Populate the slots in the order shown in the motherboard manual — typically one module per channel per CPU — and do not mix this registered DIMM with any unbuffered memory.

What ongoing care does this fanless 1.2 V DDR4 RDIMM require after installation?

Keep the server air filters clean so airflow reaches the bare modules; no firmware updates or periodic replacement are needed unless a module fails diagnostics.
