Eight green 288-pin DDR4 LRDIMM sticks in a row

OWC

OWC 2TB (8×256GB) DDR4 3200 CL22 ECC LRDIMM memory upgrade

SKU CH-PFYZ-Y7ETM

Eight 256 GB DDR4 3200 CL22 ECC load-reduced DIMMs totalling 2 TB for Dell PowerEdge XR11 and XR12 servers

Capacity 2TB (8 x 256GB)

  • 2 TB capacity expands server memory headroom with eight 256 GB modules
  • DDR4 3200 CL22 speed handles demanding workloads at PC4-25600 bandwidth
  • ECC load-reduced design protects data integrity in Dell PowerEdge XR11 and XR12
  • 2 V operation lowers power draw while maintaining 3200 MHz performance
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Server-grade memory kit

This OWC kit delivers two terabytes of DDR4 ECC load-reduced memory across eight 256GB modules. It is built for Dell PowerEdge XR11 and XR12 servers that require registered LRDIMM technology. Standard desktop boards cannot use this memory type.

JEDEC-compliant 288-pin LRDIMM

Each module uses the 288-pin load-reduced form factor and operates at 1.2V. The registered design reduces electrical load on the server memory bus, allowing higher densities per channel. Mixing with unbuffered or standard registered DIMMs is not supported.

3200MHz CL22 speed rating

Rated at PC4-25600 with 22-cycle latency, the kit also runs at 2133, 2400, 2666 and 2933MHz when the platform requires a lower speed. This single specification determines whether the memory matches the server's qualified vendor list.

Questions about this item

What DDR4 standard and speed does this PC4-25600 CL22 kit run at?

It operates at the JEDEC DDR4-3200 PC4-25600 standard with CL22 latency and will down-clock to 2933, 2666, 2400 or 2133 MHz if the platform requires it.

What physical slot and module count does this 2 TB kit need?

The kit contains eight 256 GB 288-pin LRDIMMs, so the server must provide eight DDR4 DIMM slots and support load-reduced ECC modules.

How are the eight LRDIMMs installed, and what common mistake should be avoided?

Populate all eight slots following the Dell PowerEdge XR11/XR12 memory population guide; do not mix these load-reduced modules with unbuffered or registered ECC DIMMs.
