OWC 64GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin 1.2V ECC Registered RDIMM Dell P2MYX server RAM

SKU CH-HAM2-18V40

A 64 GB DDR4 ECC registered DIMM running at 3200 MHz with CL22 latency for server and workstation upgrades

  • Type288-Pin DDR4 ECC RDIMM
  • CAS Latency22
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredRegistered
  • Heat SpreaderNo
  • 64GB capacity doubles server memory headroom
  • DDR4 3200 CL22 delivers 25600 MB/s peak bandwidth
  • ECC registered design corrects errors for uptime
  • 2V operation cuts power draw per module
  • Backward compatible with 2133, 2400, 2666, 2933 MHz systems

What it is

This is a single 64GB DDR4 3200 ECC registered RDIMM built to the PC4-25600 JEDEC standard with CL22 timing and 1.2V operation. It uses a 2Rx4 288-pin layout without a heat spreader and is sold new as a direct replacement for Dell P2MYX systems.

Who it suits

It suits administrators upgrading Dell PowerEdge servers or compatible workstations and NAS units that require registered ECC memory at 3200, 2933, 2666, 2400 or 2133 MT/s. It will not work in standard desktop motherboards, nor can it be mixed with unbuffered or load-reduced DIMMs.

Capacity and headroom

One module delivers 64GB of error-correcting capacity for virtualisation hosts, database nodes or high-thread-count compute tasks. Headroom ends when the platform reaches its maximum DIMM count or total memory limit, at which point additional modules or higher-density parts would be required.

Perguntas sobre este artigo

Does my motherboard need 288-pin DDR4 ECC RDIMM slots to install this 64GB module?

Yes, the module is a 288-pin DDR4 ECC Registered DIMM and requires a motherboard with matching RDIMM slots that support ECC memory.

Can I run this 3200MHz module alongside my existing 2666MHz DDR4 ECC registered DIMMs?

Yes, the module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds and will operate at the lowest common speed.

How do I confirm the module is running at PC4-25600 3200MHz CL22 after installation?

Check the BIOS memory information or use a system utility like CPU-Z to verify the reported speed, CAS latency of 22 and ECC registered status.
