Server-Specific DDR4 Kit

This OWC kit provides 256 GB of DDR4 3200 CL22 ECC Load-Reduced memory in two 128 GB modules. It is built for Dell PowerEdge C6525, R6515 and R7515 servers and workstations. The 288-pin LRDIMMs operate at 1.2 V and carry JEDEC-standard PC4-25600 ratings.

Replacing Lower-Capacity DIMMs

The kit upgrades systems running 2133, 2400, 2666 or 2933 MHz DDR4 by adding higher-density 8Rx4 modules at 3200 MHz. The jump is worthwhile when virtualisation hosts or database nodes need more memory channels populated without exceeding the platform's supported rank-per-channel limit.

For PowerEdge C6525, R6515, R7515 Owners

This memory suits administrators expanding compatible Dell PowerEdge platforms with validated ECC LRDIMMs. It is not for desktop PCs, consumer workstations or any system that requires unbuffered or standard registered DIMMs, as the load-reduced protocol is electrically incompatible.

Questions about this item

Does this 288-pin LRDIMM kit fit the Dell PowerEdge R6515 and R7515 memory slots?

Yes, the 2x128GB DDR4 3200 CL22 8Rx4 modules are validated for PowerEdge C6525, R6515 and R7515 servers and use the standard 288-pin DDR4 LRDIMM form factor.

What is the correct installation sequence for these 8Rx4 load-reduced DIMMs?

Populate identical 128GB modules in matched channel pairs per the server's memory population guide; mixing with unbuffered or registered ECC DIMMs is not supported.

When should I expect to replace these 128GB LRDIMM modules?

The modules are JEDEC and RoHS compliant with a limited lifetime warranty; replacement is only needed if a module fails diagnostics or capacity requirements change.
