Server memory upgrade kit
This OWC kit supplies 256 GB of DDR4 ECC Registered RDIMM memory across eight 32 GB modules. It is built for Cisco UCS B200 M4 and C220 M4 servers and workstations that require registered error-correcting memory. Standard desktop computers cannot use these modules.
Registered ECC constraints
Registered ECC RDIMMs cannot be mixed with unbuffered or load-reduced DIMMs in the same system. The memory operates at 1.2 V with a CAS latency of CL17 and conforms to the PC4-19200 (DDR4 2400) JEDEC standard. Compatibility is limited to platforms that explicitly support registered ECC DDR4.
Eight-module capacity limit
The kit delivers its full 256 GB only when all eight 32 GB modules are installed in a supported Cisco UCS server. Systems with fewer DIMM slots or a lower maximum memory ceiling will not accept the complete kit.

LaosKüsimused selle toote kohta
Should I buy this 256GB kit or look for a different capacity for my Cisco UCS server?
This kit provides 256GB total using eight 32GB modules, matching the 288-pin DDR4 2400 CL17 ECC Registered RDIMM specification required by the Cisco UCS B200 M4 and C220 M4.
What does the DDR4 2400 PC4-19200 rating mean when the modules are installed in a Cisco UCS B200 M4?
The modules will run at 2400MHz with CL17 latency at 1.2V, delivering the full PC4-19200 bandwidth the platform expects from registered ECC RDIMMs.
Will these 288-pin DDR4 ECC Registered RDIMMs work in a standard desktop motherboard?
No, they are registered ECC modules designed for server and workstation platforms such as the Cisco UCS B200 M4 and C220 M4 and are not compatible with unbuffered desktop memory slots.
