Four green 288-pin LRDIMM modules with black chips

OWC

OWC 1TB (4×256GB) DDR4 3200 CL22 ECC Load Reduced LRDIMM memory upgrade

SKU CH-521N-BTVD4

Four 256 GB DDR4 3200 CL22 ECC load-reduced DIMMs totalling 1 TB for Dell PowerEdge XR11 and XR12 servers

Capacity 1TB (4 x 256GB)

  • Massive 1 TB capacity from four 256 GB modules
  • DDR4 3200 speed with CL22 latency for responsive server workloads
  • ECC load-reduced design protects data integrity in critical applications
  • 2 V operation reduces power draw and heat in dense chassis
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

1 TB DDR4 ECC LRDIMM kit for Dell PowerEdge XR11

This kit provides 1 TB of DDR4 memory in four 256 GB load-reduced DIMMs. It is built for Dell PowerEdge XR11 and XR12 servers and workstations that require ECC load-reduced modules. It will not work in standard desktop computers or systems that use unbuffered or registered ECC memory.

DDR4 3200 PC4-25600 CL22 with backward speed support

The modules run at 3200 MHz with a CAS latency of 22 at 1.2 V. They are also compatible with 2133, 2400, 2666 and 2933 MHz bus speeds, allowing use in systems that operate at those lower frequencies. The 288-pin form factor fits DDR4 LRDIMM slots only.

Four 256 GB 8Rx4 modules deliver the 1 TB total

Each of the four DIMMs is a 256 GB 8Rx4 device, so the kit reaches 1 TB only when all four are installed together. Buyers who need a smaller capacity or who have fewer than four available slots cannot use this kit as supplied.

Questions about this item

Should I buy the 4×256 GB kit or look for a different capacity?

The kit provides 1 TB total across four 256 GB modules; choose it when your Dell PowerEdge XR11 or XR12 needs the maximum supported capacity in a matched set.

What does the 3200 MHz rating mean once the modules are installed?

The modules run at 3200 MHz CL22 by default and will down-clock automatically to 2933, 2666, 2400 or 2133 MHz if the platform requires a lower speed.

Is the 288-pin LRDIMM interface compatible with standard RDIMM slots?

No — these are ECC Load-Reduced DIMMs that must not be mixed with unbuffered or registered DIMMs; they only work in platforms designed for LRDIMM memory.
