Overview

The purpose of this document is to provide guidance for users on how to optimally

configure the system memory in the ThinkStation P920 and P720 platforms in

order to provide the best performance.

Section 1 –Platform Memory Architecture

The launch of the Intel® Purely platform has brought with it some exciting

changes to the system architecture for memory as compared to previous

workstation platforms. Newly added features such as support for 6 channels of

memory (per CPU) and a higher top supported memory bus speed combine to

provide users with significantly improved memory performance in their

workstations. Both the ThinkStation P920 and ThinkStation P720 have been

designed to take advantage of these new architecture enhancements to the

memory subsystem.

Section 2 –P920 Memory Configurations

The ThinkStation P920 is Lenovo’s largest and most powerful workstation built to

date. The dual CPU design has 16 total DIMM slots (8 per CPU) with a top

supported memory bus speed of 2666MHz

. With each CPU supporting 8 DIMM

slots, the P920 can take full advantage of all 6 channels of memory support offered

by the new Intel® Xeon® E5 Skylake CPUs. Figure 1 below shows a visual

reference of the DIMM slot layout for the P920 platform.

Actual memory bus speed is determined by the CPU(s) selected.

The following guidelines are recommended by Lenovo for obtaining the best

memory bandwidth from your P920 when filling DIMM slots:

In single CPU configurations, only DIMM slots for CPU1 can be

utilized. For dual CPU configurations, all DIMM slots can be utilized.

In dual CPU configurations, it is optimal to balance memory across

CPUs. This applies to both DIMM quantity and capacity. While the

system will function with unbalanced DIMMs, overall memory

performance could be affected.

For best memory bandwidth performance, Lenovo recommends

optimizing the overall memory configuration to use 6 DIMMs per

CPU. DIMMS A1 and D1 (for each CPU) can be used where overall

memory capacity is prioritized over memory bandwidth.

Once DIMM quantity and DIMM capacity have been balanced across

CPUs (if necessary), users should follow the recommended fill order

for each CPU found in Figure 2. Largest capacity DIMMs should be

installed first if using mixed DIMM capacities.

Figure 2 shows the recommended DIMM slot fill order for each CPU installed in the

system.

Note: Memory configurations using 5 DIMMs or 7 DIMMs per CPU are not recommended as they

are unbalanced configurations that could result in memory performance degradation.

- 5 DIMM per CPU and 7 DIMM per CPU configurations will function, but should be avoided as

they present an unbalanced load to the CPU that could result in memory bandwidth degradation.

- 8 DIMM per CPU configurations represent an unbalanced load to the CPU, but these

configurations can be used where overall memory capacity takes priority over bandwidth. For

maximum memory bandwidth, Lenovo recommend optimizing on 6 DIMMs per CPU if possible.

Section 3 –P720 Memory Configurations

TCPOUhe ThinkStation P720 is the latest compact dual processor workstation.

Like the P920, it also features a dual CPU design. But in an effort to maintain the

smaller chassis size the P720 utilizes a 12 DIMM slot design (6 DIMMs per CPU).

This allows P720 to take full advantage of all 6 memory channels offered by the

new Intel® Xeon® E5 Skylake CPUs in a single DIMM per channel configuration

and also support the highest memory bus speed of 2666MHz

. Figure 3 shows a

visual representation of the DIMM slot layout for the P720 platform.

installed first if using mixed DIMM capacities.
