[Problem] Missing BIOS tRC RAM Timing Settings

BIOS/UEFI Modding BIOS Modding Guides and Problems

My motherboard doesn’t present any control of the tRC RAM timing to the user, but it appears there is a setting controlling it at handle 0815 that I can see in AMIBCP. Is there any way to add this option to the RAM configuration menu within the BIOS?

This isn’t a request for someone to do this - I’m just looking for any guidance on how I’d go about doing this. If it fails, I have the necessary tools to reflash, so I’m not concerned with that.

Motherboard is ASRock Z77 OC Formula. I’ve attached the BIOS.

You found tRC timing?

Could you tell me what/how you made changes here? I see that the handle numbers have been shifted and that a few options in the overclocking menu have been changed to “user.”

To be clear, the issue isn’t that the overclocking menu is hidden. It is specifically that the tRC handle does not exist in the overclocking menu but that it does appear to exist in the BIOS.

tRC setting that is not tied to menu:
