  • Replaces Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG for validated compatibility

Cisco UCS C240 M4 Memory Kit

This 128 GB kit supplies eight 16 GB DDR4 2400 CL17 ECC registered DIMMs built for the Cisco UCS C240 M4 server. The modules run at 1.2 V and use a 1Rx4 organisation with 288-pin RDIMM form factor. They replace Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG. The kit targets administrators who need to maximise memory capacity in that specific platform.

Sustained Load Behaviour

ECC registered operation corrects single-bit errors and registers address and control signals, reducing electrical load on the memory controller during continuous workloads. The CL17 latency and 2400 MT/s data rate deliver steady throughput for virtualisation, database and compute tasks. Because the modules are registered and 1Rx4, they maintain signal integrity across all eight slots without the timing penalties of mixed-rank populations.

Compatibility Check

Verify the server is a Cisco UCS C240 M4 and that all eight DIMM slots are free for a matched population. This memory will not work in standard desktop systems and cannot be mixed with unbuffered or load-reduced ECC modules. Confirm the platform firmware supports 16 GB registered DIMMs at 2400 MT/s before ordering.

Domande su questo articolo

How much power does the 1.2V DDR4 2400 kit draw when the Cisco UCS C240 M4 runs all day?

Each 16GB module operates at 1.2V; the eight-module kit totals 128GB and conforms to standard DDR4 2400 power specifications for registered ECC DIMMs.

What must the Cisco UCS C240 M4 already have for this 288-pin RDIMM kit to work?

The server needs free 288-pin DDR4 RDIMM slots that support ECC registered memory at 2400 MT/s and a BIOS that recognises 1Rx4 16GB modules.

Can I mix these 1Rx4 CL17 modules with the existing UCSMR1X161RVA or UCSMR1X161RVG DIMMs in my C240 M4?

Yes, they replace those Cisco part numbers directly; do not mix with unbuffered or load-reduced ECC DIMMs.
