Known Issues

1. Some G.Skill memory kits will not run their XMP 3200MHz profile stable.

Possible Solution: Set tRC to 75, tMAW.MAC to 1, Disable Gear Down and AM4 Boot Training.

2. Roccat Kulo 7.1 headsets will not always be initialised properly if they are left plugged in to a USB port when the system is booted.

Possible Solution: Try the latest Asmedia USB drivers, along with updating the drivers for your audio card. Contact Roccat to see if they have a updated driver.

3. Front panel audio problems in the form of sometimes experiencing peculiar high pitch sounds with the Arctis 3 headphones.

Possible Solution: Update Asmedia USB and audio drivers.


3066-3200MHz Memory Tested - X370 K4

This will be a collaberative community effort as I definitely don't have enough time to test a load of memory kits but anyone who wants to partake in this effort there are some strict guidelines to follow;

HCI Memtest MUST be used, with enough instances open to fully utilise installed memory. Free or paid for version is ok (paid for version is only like $5).
HCI MUST be run for a minimum of 15 hours.
All changed options to attain stability need to be provided.
A screenshot with all instances of HCI running plus task manager open on the "Performance" tab needs to be provided for verification.

Results from people will be added here, hopefully aiding those having issues. EDIT: Testing is finished with the current timings I was working on so heres the first kit that can be added to the 3200MHz list for the K4;

F4-3200C15D-16GVK (2x8GB) - Samsung B-Die.

Tested Timings: 16-15-15-15-35, tMAW.MAC 1, tRC 75, Gear Down Disabled, AM4 Advanced Boot Training Disabled

Note: My aim was to find some timings that should be absolutely stable on the X370 K4, if you want to experiment a bit try 16-14-14-14-25, tRC 65.
