LX2160A COM Tested SO-DIMM Memory

Introduction

The intention of this page is to describe what has been tested on the LX2160A 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 LX2160A 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 first published around when the LX2160A module started shipping to customers; it is expected to grow slightly in case all memory devices passes as in the current state and will update only the failed cases.

The list is sorted alphabetical.

Notice that the above tests were performed when LX2160A COM express type 7 module core VDD was set to 780mV; which is the default setting when shipping the module.
