This 4GB RAM is 100% compatible with HP ProLiant BL490c Gen7 (G7).

Memory Configuration: Our memory team is happy to assist you in choosing the right RAM and configuring your server.

Technology:

• UDIMM ECC 4GB RAM 12
• RDIMM 16GB RAM 18
• RDIMM 32GB RAM 12

UDIMM ECC memory and RDIMM (Registered) server memory cannot be used together. Therefore, when upgrading, you should know which memory is already installed or upgrade completely to RDIMM memory.

Principles of Memory Configuration:

• Memory slots are organized in groups of three.
• Each group of three can have a maximum of 2 slots for UDIMM ECC memory.
• Each group of three can have a maximum of 2 slots for 4Rank RDIMM memory.
• The different groups of three slots do not need to have the same capacities.
• Only the memory slots where the respective CPU is present can be used.

Memory Configuration for Good System Performance:

• Distribute the memory evenly across the memory slots and evenly across the CPUs.
• With three identical memory modules per group of three slots, performance can be up to three times faster compared to filling the group with only one memory module.
• If more than one CPU is present, the memory should be configured identically (mirrored to the other CPU) per CPU.
