Green rectangular DDR4 RDIMM module with black chips, no heat spreader, 288 gold pins along bottom edge

OWC

OWC 64GB DDR4 3200 CL22 ECC RDIMM 2Rx4 memory upgrade

SKU CH-RBTC-0G020

A 64 GB DDR4 3200 ECC registered RDIMM for Gigabyte G292-Z44, G292-Z45, G292-Z46, G482-Z51 and G482-Z52 servers and workstations

  • Capacity64GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS Latency22
  • Voltage1.2V
  • ECCYes

Capacity 64GB

Struck-through versions exist but are not stocked here.

  • 64GB capacity expands server memory headroom
  • ECC registered design protects data integrity in critical workloads
  • DDR4 3200 speed matches Gigabyte G292 and G482 platform specs
  • 2V operation reduces power draw per module
  • Backward compatible with 2133 2400 2666 and 2933MHz systems

Server memory upgrade

This OWC module adds 64GB of DDR4 ECC registered memory to compatible Gigabyte server platforms. It is intended for administrators expanding capacity in workstation or NAS systems that require registered DIMMs. Standard desktop computers cannot use this module.

Registered ECC requirement

The single specification that determines compatibility is the registered ECC design. This module will not function in systems that require unbuffered or load-reduced memory and cannot be mixed with those types.

Thermals and power

Operating at 1.2V without a heat spreader, the module runs within standard DDR4 power limits for registered server memory. Passive cooling in a properly ventilated chassis is sufficient for normal workloads.

Questions about this item

What does the 3200 MHz rating mean once the module is installed in a Gigabyte G292-Z44 server?

The module runs at DDR4 3200 with CL22 latency and 1.2 V. If the platform defaults to a lower speed such as 2933 MHz, the DIMM will operate at that speed instead.

How does the PC4-25600 designation limit bandwidth in practice?

PC4-25600 indicates a peak transfer rate of 25 600 MB/s. Actual throughput is governed by the server memory controller and the number of populated channels.

What physical slot and clearance does the 288-pin RDIMM require?

It fits a standard 288-pin DDR4 RDIMM socket. The module has no heat spreader, so it occupies only the DIMM height defined by the JEDEC form factor.
