Memory Options - Lenovo System x3850 X5 Product Manual

Processor options
The x3850 X5 supports the processor options listed in the following table. The server supports up to four
processors. The E7-8000 processors support native QPI scaling to two nodes without the need for a MAX5
memory expansion unit. All Intel Xeon E7 processors support two-node scaling with MAX5. Two-node
scaling with MAX5 is supported with MAX5 V2 for System x (88Y6529) or MAX5 for System x (59Y6265).

Memory options

Lenovo DDR3 memory is compatibility tested and tuned for optimal System x 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 system warranty, and Lenovo provides service and support
worldwide.
The System x3850 X5 supports DDR3 memory. Memory is installed in memory cards. The server supports
eight memory cards, and each card holds eight DIMMs. Two memory cards are connected to each
processor. As a result, all eight memory cards are usable only when all four processors are installed.
Adding a MAX5 memory expansion unit to the server offers an additional 32 DIMM slots for a total of 96
DIMM slots per node.
The following table lists the memory options that are supported in the server and MAX5 (either MAX5 V2 or
MAX5).
Notes:
In the MAX5 memory expansion unit, do not mix DIMMs with x4 technology (DIMMs with DRAMs
that are organized with 4 data lanes, as indicated by "x4" in the description) with DIMMs with x8
technology (DIMMs with DRAMs that are organized with 8 data lanes).
In the server, you can mix DIMMs with x4 and x8 technology.
