[Official] AMD Ryzen DDR4 24/7 Memory Stability Thread

AM4 Ryzen Memory Stability Thread


Please try to remember the following



Clarify what platform and CPU you are speaking about when asking a particular question or speaking about your experience.

Quote the user you are replying to when replying.

When posting stability results, be sure to include the CPU as described in the posting results instructions.

NOTE: SOC voltage should ideally not exceed 1.2v Anything above 1.25v has the potential to cause irreversible damage.

Recommended settings ca be found here in the guide provided by ASUS: http://www.mediafire.com/file/mciue9..._Guide_v05.pdf




Happy posting!

Overview
This thread is dedicated to showing the various memory configurations of users with DDR4 on AMD Ryzen platforms.
There is no strict criteria here, all things AM4 memory overclocking welcome. However, to enter the stability chart certain criteria is to be met as this is generally speaking dedicated to showing what is obtainable on both platforms at an operational level.


If using ASUS you can also post here for help:



For stability results, using the recommendations found below and in the overview seem the most requisite on recent platforms:

Quote:Google stressapp test via W10 Bash Terminal(or another compatible Linux disti) is the best memory
stress test available. Google use this stress test to evaluate memory stability of their servers
– nothing more needs to be said about how valid that makes this as a stress test tool.


Windows 10 Installation
  • Install Bash Terminal: https://msdn.microsoft.com/en-gb/com.../install_guide
  • Install the Google Stress App test by typing: sudo apt-get install stressapptest
  • Once installed open “Terminal” and type the following: stressapptest -W -s 3600
  • You can add argument "-M" and add the the amount of memory you wish to assign to the test (90% of available memory)
  • This will run the stressapp for one hour. The test will log any errors as it runs.

Mint Installation

Quote:HCI Memtest for Windows

HCI Memtest can be run via DOS or Windows. http://hcidesign.com/memtest/

An instance needs to be opened for each individual thread, covering a total of 90-95% of memory giving the OS a little breathing room.

As an example Ryzen 7 1700 - 16GB RAM

16 instances with 850MB per instance.





NOTE: Version 5.0 notes state that it's 30% faster than previous versions. For testing densities beyond 16GB - it's recommended you use 5.0 Pro.

Stability Results

Please submit results with the following format.

GSAT Results
For sake of simplicity submitted results will only record primary timing sets, but feel free to show subsequent secondary and terts within screenshot.
Linux Mint's Stressapp test needs to be run for a minimum of 1 hour by typing stressapptest -W -s 3600 in the Terminal.
To take a screenshot in Terminal type: gnome-screenshot

HCI
HCI consider 1000% to be the 'golden standard' however for larger densities this can be time consuming. A minimal coverage of two laps (200%) is required to be added to the table for HCI for density over 16GB. 16GB or less requires a minimum of 4 laps (400%)


Example:

Silent [email protected] 1.2v---BIOS 0902---Stressapptest---1 Hour--F4-3200C14-8GTZ
Or
Silent [email protected] 1.2v---BIOS 0902---HCI---400%---F4-3200C14-8GTZ


NOTE: This is not a leaderboard, as it is not a benchmark. This thread's main purpose is to both discuss information and various results and to gauge what is possible between different configurations, DIMM capabilities, and CPU samples. Results are welcome all the way up the frequency spectrum. If it's obtainable, it should be posted! .

Should go without saying that general system and CPU stability should be gauged via the suggested means before attempting an outright memory stability test.






Have fun!
