Memory
Lenovo DDR3 memory is compatibility tested and tuned for optimal System x® and BladeCenter
performance and throughput. Lenovo memory specifications are integrated into the light path diagnostics
for immediate system performance feedback and optimum system uptime. From a service and support
standpoint, Lenovo memory automatically assumes the Lenovo system warranty, and Lenovo provides
service and support worldwide.
The BladeCenter HS23 (7875, E5-2600 v2) supports Very Low Profile (VLP) DDR3 memory RDIMMs. The
server supports up to eight DIMMs when one processor is installed and up to 16 DIMMs when two
processors are installed. Each processor has four memory channels, and there are two DIMMs per
channel.
The following rules apply when selecting the memory configuration:
Mixing 1.5 V and 1.35 V DIMMs in the same server is supported. In such a case all DIMMs operate
at 1.5 V.
The maximum number of ranks supported per channel is eight.
The maximum quantity of DIMMs that can be installed in the server depends on the number of
CPUs, DIMM rank, and operating voltage, as shown in the "Max. qty supported" row in Table 6.
All DIMMs in all CPU memory channels operate at the same speed, which is determined as the
lowest value of:
Memory speed supported by specific processor
Lowest maximum operating speed for the selected memory configuration that depends on
rated speed, as shown under the "Max. operating speed" section in Table 6.
