Target Platform & Purpose
This 128GB DDR4 2933 ECC Registered RDIMM is built for Cisco UCS B200 M5, B480 M5, C220 M5, C240 M5 and C480 M5 servers. It suits administrators who need high-capacity registered memory with error correction for virtualisation, databases or heavy compute workloads. It will not work in standard desktop computers or consumer motherboards. Buyers who need unbuffered or load-reduced DIMMs should look elsewhere.
Pre-Installation Checks
Verify that your Cisco UCS model appears in the supported list above and that the system BIOS is current. The module runs at 1.2V with CL21 latency and an 8Rx4 organisation; mixing it with unbuffered or load-reduced memory is not supported. Confirm the server has free 288-pin DDR4 slots and that the total installed capacity does not exceed the platform limit.
Sustained-Load Behaviour
JEDEC-standard construction and ECC registration keep data integrity intact during continuous operation at 2933 MT/s. The module is also backward compatible with 2133, 2400 and 2666 MT/s bus speeds, allowing stable performance when the platform downclocks memory under heavy thermal or power constraints. No heat spreader is fitted, so adequate chassis airflow is required for long-duration workloads.

Bu ürünle ilgili sorular
What comes with the single 128GB DDR4 2933 ECC Registered RDIMM and is anything else required?
The box contains one 128GB 288-pin module; no cables, brackets or additional parts are needed for installation in a compatible Cisco UCS server.
Should I choose this 128GB 8Rx4 CL21 module or a different capacity for my Cisco UCS B200 M5?
This is a single 128GB 8Rx4 CL21 stick; select it when you need maximum density per slot, otherwise pick lower-capacity RDIMMs to match your channel population plan.
What does the 2933 MT/s rating actually deliver once the module is seated in a Cisco UCS C240 M5?
The module runs at 2933 MT/s CL21 at 1.2 V and will down-clock to 2666, 2400 or 2133 MT/s if the platform requires a lower speed.
