Capacity & Compatibility

This OWC kit supplies 128 GB of DDR5 memory in four 32 GB registered DIMMs. It is built for Dell PowerEdge R6625, R760, R7615 and R7625 servers that require ECC registered modules.

Server Builders Only

The modules suit administrators upgrading or populating the listed PowerEdge platforms with JEDEC-standard DDR5 4800 ECC RDIMMs. They will not work in standard desktop computers, consumer workstations or any system that demands unbuffered or load-reduced memory.

Registered ECC Requirement

Each 288-pin module runs at DDR5 4800 CL40 with 2Rx8 organisation at 1.1 V. The registered ECC design is the single specification that determines whether the kit fits your server; verify the platform accepts registered DIMMs before purchase.

Questions about this item

Should I choose the 128GB kit or buy single 32GB modules?

The 128GB kit contains four matched 32GB modules tested together for multi-channel operation on Dell PowerEdge R6625, R760, R7615 and R7625 servers.

What does the 4800MHz speed deliver in a Dell PowerEdge R760?

The modules run at the JEDEC-standard DDR5 4800 rate with CL40 latency, providing the maximum supported memory bandwidth for these server platforms.

Does the PC5-38400 rating limit the memory speed on a Dell PowerEdge R7615?

PC5-38400 is the peak transfer rate for DDR5 4800; the server's memory controller caps operation at this speed, so the kit will not exceed it.
