OWC 1TB (8x128GB) DDR4 2933MHz ECC Load Reduced LRDIMM Server RAM

SKU CH-5YFA-T88PC

Eight 128 GB DDR4 2933 MHz ECC load-reduced LRDIMMs totalling 1 TB for server and workstation upgrades

  • Capacity1TB (8 x 128GB)
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 1TB (8 x 128GB)

  • 1TB capacity with eight 128GB modules
  • DDR4 2933MHz speed for high-throughput server workloads
  • ECC load-reduced design protects data integrity
  • 2V operation reduces power draw
  • Backward compatible with 2133MHz, 2400MHz and 2666MHz systems

1TB DDR4-2933 ECC LRDIMM Kit

This 1TB kit contains eight 128GB DDR4-2933 ECC load-reduced DIMMs built for servers, workstations and compatible NAS systems. It runs at PC4-23400 with CL21 latency and 1.2V operation. The modules use 288-pin 4Rx4 organisation and are JEDEC and RoHS compliant.

Upgrade from lower-capacity or slower DDR4 LRDIMM

The kit replaces smaller LRDIMM sets or slower DDR4-2133, DDR4-2400 and DDR4-2666 modules in supported platforms. The jump is worth it when your workload needs maximum registered ECC capacity per slot and the platform accepts 4Rx4 load-reduced modules at 2933MHz.

Installation requires compatible server

Modules install like standard 288-pin DIMMs but must go into slots that support ECC load-reduced memory. They will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs. Verify platform qualification before fitting.

Questions about this item

Does the 288-pin DDR4 LRDIMM form factor fit my server's DIMM slots?

The modules use the standard 288-pin DDR4 LRDIMM form factor for server and workstation boards that support load-reduced memory.

What is the correct way to install the 8-module kit so the server recognises all 1TB?

Populate all eight slots following the motherboard's channel population guide; the kit is a dual-channel set and must not be mixed with unbuffered DIMMs.

How do I know when a 128GB module should be replaced?

Replace a module when the system logs uncorrectable ECC errors or the memory diagnostic reports a persistent fault on that DIMM.
