An 8 GB DDR4-2400 ECC registered RDIMM with CL15 latency and 1.2 V operation for compatible IBM servers
This 8GB registered ECC module matches IBM part 46W0825 and runs at DDR4-2400 with CL15 latency. It uses a 2Rx8 organisation on a 288-pin RDIMM form factor and operates at 1.20V. The stick is built with major-brand DRAM from Samsung, SK Hynix or Micron and is sold new with a lifetime guarantee.
Before ordering confirm that your server or workstation accepts registered ECC DDR4 RDIMMs and can populate the required 288-pin slots. The platform must also support 1.2V DDR4-2400 operation and be able to address 8GB per module. Mixing registered with unbuffered memory is not supported and will prevent boot.
Under continuous load the module maintains its rated 2400 MT/s speed at the standard 1.20V without throttling. Registered buffering reduces electrical loading on the memory controller, helping signal integrity during sustained read-write cycles. ECC correction handles single-bit errors transparently, keeping data integrity intact over long-running workloads.

The module is sold individually; no additional components are needed beyond a compatible 288-pin DDR4 RDIMM slot.
Choose this 8 GB 2Rx8 CL15 module when your server requires registered ECC memory at DDR4-2400 and the platform supports dual-rank DIMMs for maximum capacity per channel.
PC4-19200 denotes the module’s rated DDR4-2400 speed with CL15 timing; actual throughput depends on the server’s memory controller and channel configuration.
