Sure.

@Lost_N_BIOS Are you able to teach me how to mod the BIOS? I really want to try it out.

Gigabyte got back to me and fibbed that it only works on Z390 to avoid fixing the issue.

@rootuser123 - First I will make you BIOS and you test, then if success I will show you how to do the edit.
I don't think it will work though, but maybe we'll get lucky and it's not same as doing this to a voltage related setting?

This (tRC) is already unlimited setting in BIOS (?), if you have max 64 I cannot change in the way I was thinking, it's already set to unlimited (65535/0xFFFF), and not max of (64/0x40h)

Test this >> 18-22-22-38-2T Does it boot? If not, try this >> 18-22-22-40-2T

@chinobino - Due to the edit above, is crossflash Z370 > Z390 possible, or too different of chipset?
I looked at Z390 Ultra F9 BIOS, same as this one here, unlimited setting for MAX allowed, so the change made, if in F9 BIOS, is not done there.

@Lost_N_BIOS Z370 pch is a derivative of the Z270 chipset. Z390 is entirely different with different ME firmware.

Thanks, well I guess that's a no-go
Did you test the two scenarios I mentioned above? Is the BIOS telling you 64 is max for tRC, or does it just auto-change it back?

@Lost_N_BIOS When I type in value higher than 64 it will change back to Auto value.

@Lost_N_BIOS what do you think about chinobino’s idea?
