This 8GB RAM is 100% compatible with the Oracle Sun Fire X4275.

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

Principles of Memory Configuration: The 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 also 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 corresponding to the respective CPU can be used.

Memory Configuration for Optimal System Performance: Distribute the memory evenly across the memory slots and evenly across the CPUs. With three identical memory modules in each group of three slots, performance can be up to three times faster compared to configuring the group of three slots with only one memory module. If more than one CPU is present, the memory should be configured identically (mirrored to the other CPU) for each CPU.
