Server memory upgrade

This 64 GB DDR4 module operates at 3200 MHz with a CAS latency of 22 and runs at 1.2 V. It uses a 4Rx4 rank configuration and registered ECC technology for data integrity. The 288-pin RDIMM form factor fits compatible server platforms.

Compatibility check

Verify that your motherboard supports DDR4 RDIMM modules with ECC and registered buffering. Confirm the memory controller accepts 4Rx4 density and PC4-25600 speed grades. Ensure the BIOS can initialise 64 GB single-rank capacity per slot.

Warranty coverage

A lifetime replacement warranty protects the module against defects for as long as you own it. This coverage removes the cost of a replacement unit if a failure occurs. No bundled software or accessories alter the installation process.

Questions about this item

Does the 64GB module ship alone or with extra parts?

The kit contains one 64GB DDR4 3200 ECC RDIMM. No additional brackets, cables or software are included.

Why choose the 4Rx4 3200MHz version over a 2Rx8 alternative?

4Rx4 ranks let a single DIMM deliver 64GB at 3200MHz, reducing slot count while keeping ECC and registered operation.

What does the PC4-25600 rating mean for actual throughput?

PC4-25600 is the JEDEC designation for DDR4 3200; real-world bandwidth depends on the platform's memory controller and channel configuration.
