Abstract

This paper examines the architecture and memory performance of Lenovo System x and Flex System X6 platforms that are based on the Intel Xeon E7-8800 and E7-4800 v3 processors. The performance analysis in this paper covers memory latency, bandwidth, and application performance. In addition, the paper describes performance issues that are related to CPU frequency, memory speed, and population of memory DIMMs. Finally, the paper examines optimal memory configurations and best practices for the Lenovo X6 platforms.
