Certified Supermicro server memory

This 64GB DDR4 LRDIMM carries Supermicro certification for qualified platforms. It targets administrators expanding capacity in compatible rack or tower servers that require load-reduced registered ECC modules.

Quad-rank 4Rx4 organisation at 2133 MHz

The module runs at PC4-17000 with CL15 latency and 1.20V. The 4Rx4 layout determines whether the memory controller can address the full 64GB per slot, so the system memory reference guide must confirm support for this rank configuration.

Samsung M386A8K40BM1-CPB components inside

The Samsung chipset provides the underlying DRAM array for this part number. No additional accessories, software licences or cooling hardware are included with the memory module itself.

Questions about this item

What does the 64 GB capacity mean for a server workload?

A single module provides 64 GB of DDR4 memory, allowing the system to hold larger datasets in RAM and reduce swapping during heavy multitasking or virtualization tasks.

How does the DDR4 2133 PC4-17000 rating limit real-world throughput?

The module runs at 2133 MHz with a peak transfer rate of 17000 MB/s; actual bandwidth will not exceed this ceiling even if the platform supports faster DDR4 speeds.

Will the 288-pin LRDIMM form factor fit my Supermicro motherboard?

The stick uses the standard 288-pin LRDIMM layout; it installs in any DDR4 LRDIMM slot that accepts 4Rx4 quad-rank modules at 1.2 V.
