This 8GB RAM is 100% compatible with Dell PowerEdge T420. 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: Maximum capacity according to memory technology UDIMM ECC 24GB RAM, RDIMM 96GB RAM, LRDIMM 192GB RAM
• 2 CPUs: Maximum capacity according to memory technology UDIMM ECC 48GB RAM, RDIMM 192GB RAM, LRDIMM 384GB RAM

ECC DIMM, Registered DIMM, and Load Reduced LRDIMM memory modules must not be mixed. Therefore, when upgrading, you should know which memory is already installed or upgrade completely to RDIMM memory.

Principles of memory configuration:

• The memory slots are organized in pairs.
• The different pairs of slots do not need to have the same capacities.
• Only the memory slots corresponding to the respective CPU can be used.

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.
