512GB ECC LRDIMM Kit for Dell PowerEdge

This kit delivers 512GB of DDR4 3200 memory across four 128GB load-reduced DIMMs. It is built for Dell PowerEdge XR11 and XR12 servers that require ECC LRDIMM modules. The modules run at 1.2V with CL22 latency and a 4Rx4 organisation. They are JEDEC-standard and RoHS compliant.

Suited for server upgrades, not desktops

This memory fits administrators expanding Dell PowerEdge XR11 or XR12 platforms with validated ECC load-reduced DIMMs. It will not work in standard desktop computers or systems that only accept unbuffered or registered ECC modules. Mixing with those other memory types is not supported.

512GB capacity with DDR4 3200 headroom

The four modules provide 512GB total capacity for heavy virtualisation or in-memory workloads. Rated at DDR4 3200, the kit also runs at 2133, 2400, 2666 and 2933 speeds when the platform requires it. Maximum capacity is limited to the 512GB supplied in this kit.

Questions about this item

What server model must I already own for this 4x128GB DDR4 3200 CL22 ECC LRDIMM kit to work?

The kit is validated for Dell PowerEdge XR11 and XR12 systems. It requires a server that accepts 288-pin DDR4 LRDIMM modules with ECC load-reduced support.

How will these 4Rx4 3200MHz modules behave if I keep existing 2666MHz or 2933MHz DDR4 ECC LRDIMMs in the same server?

The modules are backward compatible with 2133, 2400, 2666 and 2933MHz speeds. All installed memory will run at the lowest common frequency and matching timings.

How can I confirm the 512GB kit is operating at CL22 1.2V after installation?

Enter the system BIOS or use a hardware inventory tool such as iDRAC; it should report 512GB total, DDR4 3200 PC4-25600, CL22 latency, 1.2V and ECC load-reduced status.
