Eight green 288-pin DDR4 LRDIMM sticks in a row

OWC

OWC 2TB (8x256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM Memory Upgrade Kit

SKU CH-JWD6-85456

Eight 256 GB DDR4 3200 ECC load-reduced DIMMs totalling 2 TB for Dell PowerEdge MX750c, R650 and R750 servers

Capacity 2TB (8 x 256GB)

  • 2 TB capacity with eight 256 GB modules
  • DDR4 3200 PC4-25600 CL22 for high-throughput server workloads
  • ECC load-reduced design maintains data integrity under heavy load
  • 2 V operation reduces power draw in dense configurations
  • Compatible with Dell PowerEdge MX750c, R650 and R750

2TB ECC Load-Reduced Kit

This kit delivers 2TB of DDR4 3200 memory across eight 256GB LRDIMMs. It is built for Dell PowerEdge MX750c, R650 and R750 servers and workstations that require registered ECC load-reduced modules. Standard desktop systems cannot use this memory type.

Replaces lower-capacity LRDIMMs

Swapping smaller load-reduced DIMMs for these 256GB modules lets a compatible server reach 2TB in eight slots. The upgrade is worthwhile when workloads need maximum per-slot density and the platform supports 8Rx4 organisation at 3200MHz.

Fits eight 288-pin slots at 1.2V

Modules operate at 1.2 volts and run at 3200MHz with CL22 timing, while also supporting 2933, 2666, 2400 and 2133MHz speeds. They must not be mixed with unbuffered or standard registered ECC DIMMs, and the system must provide eight DDR4 LRDIMM sockets.

Questions about this item

Does this 288-pin LRDIMM fit a Dell PowerEdge R750 server?

Yes — the kit is validated for Dell PowerEdge R750, R650 and MX750c systems.

What slot population rule must I follow when installing these 8Rx4 modules?

Fill all eight channels identically; do not mix LRDIMMs with unbuffered or registered DIMMs.

When will these 1.2 V DDR4 modules need replacement?

They are rated for the server’s service life; replace only if a module fails diagnostics.
