System-Specific Server Memory Kit

This OWC kit provides 64 GB of DDR4 ECC Registered memory in a matched pair of 32 GB modules. It is built for Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4 servers that require registered DIMMs with error correction.

Suited for Compatible Cisco UCS Servers

The modules fit only systems that accept 288-pin DDR4 2400 CL17 2Rx4 registered DIMMs at 1.2 V. They will not work in standard desktop computers, laptops, or any platform that requires unbuffered or load-reduced memory.

Registered ECC with 2Rx4 Organisation

The 2Rx4 registered ECC design is the single specification that determines whether this kit matches your server’s memory architecture. Verify that your Cisco UCS model lists this exact configuration before ordering.

Questions about this item

Should I buy the 64GB kit as two 32GB modules or look for a different capacity?

The kit is sold only as a matched pair of two 32GB modules totalling 64GB; no other capacities are offered for this part number.

What does the 2400MHz rating mean once the modules are installed in a Cisco UCS server?

The memory will run at 2400MHz with CL17 latency at 1.2V, provided the server’s memory controller supports that speed; otherwise it will downclock to the highest supported frequency.

Does the 288-pin DDR4 ECC Registered interface limit the maximum speed or capacity I can use?

The 288-pin registered DDR4 form factor caps this kit at 2400MHz and 32GB per module; it cannot be mixed with unbuffered or load-reduced DIMMs.
