Memory Training Algorithms with asterisks - Asus Z790 Hero

I use an Asus Maximus Z790 Hero motherboard.

What does the asterisk next to the name of the memory training algorithm mean?

Hi @woopsie,

These are originally from Intel code, and likely due to being the most relevant MRC related settings (you'll likely find they're highlighted on other vendor boards also).

The boards are more than pretty good at setting these anyway. Were you just curious or are you having difficulties tuning memory?

1. So these settings with an asterisk are not dangerous and can be enabled manually?

2. But how does the motherboard set these asterisked options? For example, for "DIMM ODT Training* [Auto]" will it always mean [Auto]=Enabled?

3. If I set any option with an asterisk to [Disabled] then memory training will always fail?

Probably both.

 

1. No, they're not "dangerous".
2. Auto, I would surmise for ODT will be enabled by default as this aids impedance matching.

feel free to to experiment with toggling on or off, but shouldn't be necessary. If it is, the overclock stability is probably conditional anyway.

I haven't needed to adjust any training parameters up to 8600MT.
