CN913x COM Tested SO-DIMM Memory

Introduction

The intention of this page is to describe what has been tested on the CN913x COM express type 7 module; what has passed and what has failed.

Testing Methodology

The testing methodology is mainly focused on running multiple instances of Linux memtester tool (as the core count) with variable buffer size where the buffer size is at least L3 cache in size.

The initial condition varies where one time the DDR training is conducted while all devices after power off; so room temperature is the die junction and then using different tools we reach with processor junction temperature into it’s max (105c in case of CN913x SoC).

Tested Memory Table

All SO-DIMMs that are tested are SO-DIMM DDR4 type with different sizes, speeds, with/without ECC and industrial temperature support.

The table is based on modules that SolidRun have tested and on modules that are being used and were validated by customers.
