64 GB DDR4 ECC module

This Samsung M393A8G40AB2-CWEBY stick delivers 64 GB of DDR4 memory rated at 3200 MHz with ECC support. It operates at 1.2 V and conforms to the PC4-25600 standard for server and workstation platforms.

Not for non-ECC consumer boards

Yes, it uses the standard DDR4 DIMM form factor with 288 pins, matching the slot on compatible server and workstation motherboards.
