SK hynix HMA42GR7MFR4N-TF 64GB DDR4-3200 REG ECC server RAM

SKU CH-W5Y0-Q0GPQ MPN HMA42GR7MFR4N-TF

A 64 GB registered ECC DDR4 DIMM running at 3200 MT/s with a 1.2 V operating voltage

  • Registered ECC protects data integrity in critical workloads
  • 64 GB capacity expands server memory headroom
  • DDR4-3200 speed delivers high bandwidth throughput
  • 288-pin DIMM fits standard registered memory slots
  • Single 1.2 V module simplifies high-density configurations

64GB DDR4-3200 registered ECC module

This single 64GB DDR4-3200 module delivers registered ECC memory for servers and workstations that require error correction and signal buffering. It suits administrators building high-capacity systems where data integrity outweighs raw latency.

PC4-25600 bus speed and registered design

The PC4-25600 rating sets the practical throughput ceiling, while the registered architecture adds one clock cycle of latency to reduce electrical load on the memory controller. Systems must support registered DDR4 DIMMs and ECC functionality; consumer platforms that accept only unbuffered non-ECC memory cannot use this module.

288-pin DIMM at 1.2V with 2Rx4 organisation

The standard 288-pin DIMM form factor fits server motherboards designed for registered memory, and the 1.2V operating voltage matches the DDR4 baseline. Dual-rank 2Rx4 organisation increases density per slot, so fewer modules are needed to reach large totals, but each rank adds capacitive load that can limit maximum populated speed on some boards.

商品問答

Is this the 64GB module or a kit of smaller sticks?

The listing is for a single 64GB DDR4-3200 registered ECC DIMM, not a multi-stick kit.

What does PC4-3200 (DDR4-25600) mean for actual throughput?

The module runs at 3200 MT/s, giving a peak bandwidth of 25600 MB/s when installed in a compatible server platform.

Does the 288-pin registered DIMM fit standard DDR4 server slots?

Yes, it uses the 288-pin registered DIMM form factor used by DDR4 server motherboards that support registered memory.
