OWC 8GB DDR4 2400 ECC RDIMM

This 8 GB DDR4 2400 module is built for servers, workstations and NAS systems that require ECC registered memory. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. The 288-pin RDIMM matches the Samsung M393A1K43BB0-CRC specification exactly.

Thermals noise and power draw

Operating at 1.2 V with a CL17 latency, the module draws minimal power and generates little heat without a spreader. Registered buffering reduces electrical load on the memory controller, helping keep system thermals stable during continuous workloads. Silent solid-state operation adds no audible noise to the chassis.

Build fit and requirements

The stick fits any 288-pin DDR4 RDIMM slot that supports PC4-19200 speeds and registered ECC. It frees a standard DIMM slot for additional registered modules of the same type. Builders needing unbuffered memory, desktop compatibility or higher capacities must choose different modules.

Points forts

  • ECC registered design protects server data integrity
  • DDR4 2400 speed with CL17 latency for responsive workloads
  • 2 V operation reduces power draw in dense systems
  • 288-pin RDIMM form factor fits standard server slots
  • JEDEC and RoHS compliant for warranty-safe upgrades

Questions sur cet article

How do I install this 288-Pin DDR4 ECC RDIMM and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-Pin module with the slot key, press firmly until both clips lock, then verify in BIOS that ECC Registered mode is active — skipping the BIOS check is the common oversight.

What maintenance or replacement will this 8GB DDR4 2400 module need over time?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.2V, so replacement only occurs if a memory test reports correctable ECC errors rising above threshold or if capacity must be increased.

What limit appears first when this CL17 1Rx8 RDIMM runs sustained workloads?

The CL17 latency at 2400 MT/s sets the throughput ceiling; sustained use will hit bandwidth limits before thermal throttling because the module operates at standard 1.2V without a spreader.
