This 8GB RAM is 100% compatible with the Fujitsu Primergy CX420 S1.

What memory configuration is possible? Our memory team is happy to assist you in choosing the right RAM and configuring your server.

Technology:
1 CPU - 12 slots
2 CPUs - 24 slots

Maximum RAM expansion based on the number of CPUs and memory slots:
UDIMM ECC
32GB RAM (8 x 4GB)
64GB RAM (16 x 4GB)
RDIMM
128GB RAM (8 x 16GB)
256GB RAM (16 x 16GB)

Principles of memory configuration:
There are 4 memory channels per CPU, each with 2 memory slots. UDIMM ECC memory and RDIMM (Registered) server memory cannot be used together. Therefore, when upgrading, you should know which memory is already present or upgrade completely to RDIMM. Memory slots without a processor must not be populated. Higher memory frequencies may adjust to other memory clock rates in the system environment and support correspondingly slower clock rates. Low Voltage memory with 1.35V will be clocked at 1.5V when mixed with 1.5V memory due to the fallback option available in the memory.

Memory configuration for good system performance:
Distribute the memory evenly across the memory slots and evenly across the CPUs. If more than one CPU is present, the memory should be configured identically (mirrored to the other CPU) per CPU.
