Flex System x240 Compute Node (E5-2600 v2) 13

Memory options

DDR3 memory is compatibility tested and tuned for optimal performance and throughput. Memory

specifications are integrated into the light path diagnostics for immediate system performance feedback

and optimum system uptime. From a service and support standpoint, memory automatically assumes the

system warranty, and Lenovo provides service and support worldwide.

The following table lists memory options available for the x240 compute node with E5-2600 v2

processors. DIMMs can be installed one at a time, but for performance reasons, install them in sets of

four (one for each of the four memory channels).
