Lenovo ThinkServer RD540 compatible upgrades

These upgrades are guaranteed compatible when you order from Crucial.com

Notes about your system:

Actual memory operating speed depends on processor memory controller speed, installed memory speed, and quantity of memory DIMMs. By default, the voltage of LV RDIMM is 1.5V and can be changed to1.35V in BIOS setting.
When using Intel Xeon E5-2600 series processors, LV RIMM is needed to run at 1.5V to support all 20 memory DIMM sockets.
If LV RIMM runs at 1.35V, only 16 memory DIMM sockets are functional (8 of 12 for CPU 1, 8 for CPU 2)

Your system may support multiple memory configurations based on the density, quantity and type of memory modules installed. Please consult the documentation for your specific system.
