64GB DDR4 3200 ECC RDIMM for Supermicro H11DSi

This 64GB registered DIMM runs at DDR4 3200 with CL22 latency and ECC protection. It is built for the Supermicro H11DSi motherboard and AMD EPYC platforms. The module uses 2Rx4 organisation and operates at 1.2V.

Sustained load behaviour with ECC registered design

Registered buffering and on-die ECC keep data integrity intact during continuous server workloads. The 1.2V operating voltage helps maintain stable thermals under prolonged utilisation. Major OEM chips from Samsung Micron or Hynix are stress tested under load before shipping.

Upgrades from lower capacity

Replacing smaller unregistered sticks with this 64GB RDIMM adds capacity and error correction for mission critical tasks. The jump is worth it when the board requires registered memory and the application demands ECC reliability. Builders needing unbuffered or non-ECC memory should look elsewhere.

Questions about this item

What voltage does this 1.20 V DDR4 RDIMM draw when the server runs continuously?

The module operates at 1.20 V, the standard DDR4 voltage, so power draw stays at the JEDEC level during sustained workloads.

Does the Supermicro H11DSi motherboard need to be already installed for this 288-pin RDIMM to function?

Yes, the module is built for the Supermicro H11DSi platform and requires that motherboard with an AMD EPYC processor to operate.

Will this 64 GB 2Rx4 CL22 kit run at 3200 MT/s on a first-generation EPYC CPU?

The memory is rated DDR4 3200 PC4-25600 CL22; actual speed depends on the CPU memory controller and motherboard BIOS configuration.
