64 GB DDR4 ECC RDIMM for servers

This 64 GB DDR4 3200 module is built for servers and workstations that require registered ECC memory. It uses a 2Rx4 organisation and runs at 1.20 V with CL22 latency. The stick is compatible with Samsung M393A8G40CB4-CWE and similar OEM platforms.

Check DDR4 RDIMM slot support and rank limits

Verify that your motherboard accepts 288-pin DDR4 RDIMM modules and can address a 2Rx4 64 GB stick. Confirm the maximum capacity per slot and the total rank count allowed per channel. Ensure the BIOS is current enough to initialise this density at 3200 MT/s.

Steady throughput under continuous server loads

Modules are stress-tested under sustained load to validate stability for mission-critical environments. Registered signalling and on-die ECC maintain data integrity during long compute or virtualisation runs. The 1.20 V operation keeps thermals manageable inside dense chassis.

Questions about this item

Does the module ship alone or with additional parts such as a heat spreader or cable?

The module ships as a single 64 GB stick without a heat spreader or any extra accessories.

When should I choose the 2Rx4 registered ECC version instead of a single-rank or unbuffered alternative?

Choose this 2Rx4 RDIMM when your server motherboard requires registered ECC memory and can address dual-rank modules for maximum capacity per slot.

What does the 3200 MT/s rating mean once the DIMM is installed in a live server?

The module will run at up to 3200 MT/s with CL22 latency at 1.2 V provided the platform supports DDR4-3200 registered ECC operation.
