Memory
Lenovo DDR3 memory is compatibility tested and tuned for optimal ThinkServer performance and
throughput. From a service and support standpoint, Lenovo memory automatically assumes the system
warranty, and Lenovo provides service and support worldwide.
The RS140 server has four DIMM slots, and it supports DDR3 UDIMMs with ECC memory protection. The
processor has two memory channels and supports two DIMMs per channel.
The following rules apply when selecting the memory configuration:
The RS140 server supports memory configurations with 1, 2, 3, or 4 UDIMMs.
The RS140 server supports up to 1600 MHz memory speeds for one DIMM per channel and two
DIMMs per channel configurations, provided that the processors support this memory speed (see
Table 3 for details).
The following table summarizes memory speeds and capacities that are supported by the RS140 server.
