ROG Maximus XII Apex

Hi to all. I trying for a week to stable 4800 1T on my APEX XII, cuz on GENE XI i can do it. Only yesterday I got it.
I modified 0088 bios in ASUS BIOSmart, I tweaking memory training algoritms. Plz check my bios on ur 10xxx cpu with single rank and dual rank b-die, it will be easy overcloked to 1T, but idk how dual rank can work on this bios. For dual rank u need switch rank margin tool to enabled from disabled. This bios can easy boot 5200 19-19 1T in bios on ambient 25С temperature. I think it is very helpful to bench on 5000+ 1T.

Flash bios by flashback.
P.S. TPM 2.0 and Secure boot are enabled by default in bios for WIN11 work correctly. PPD always is disabled by bios. Don't use ur .CMO profiles from stock 0088, cuz it will be broke my hidden settings. Sorry for my English.

All tweaks can helps you on my bios with dual rank 

Rank Margin Tool [Disabled] - for single rank. Will use enabled for dual.

Command Voltage Centering [Disabled] try [Enabled] check on and off

Use vref 1.48-1.55 on dual rank

DRAM CTRL REF Voltage on CHA [Auto]

DRAM CTRL REF Voltage on CHB [Auto]

Single don't needed manual setting on vref

Thank you very much for your work! When I return to CML OC, I will try this bios after removing ucode. I haven't heard of much DR testing for 1t but I can try it. I'm looking forward to trying SR. It will be a while before I get around to it, though.

By chance, can you explain what you changed to the memory algorithms? I'm curious what was modded and if it could affect performance.

Changes in memory training algorithms:

LPDDR4 Write DQ DQS Retraining [Disabled]

Early Write Time Centering 2D [Disabled]

Early Read Time Centering 2D [Disabled]

Late Command Training [Enabled]

Command Voltage Centering [Disabled]

Rank Margin Tool [Disabled] - for single rank

CMD Drive Strength and Tx Equalization [Disabled]

Trace Centering [Disabled]

Hidden settings in bios, by default it's in enabled:

SA GV [Disabled]

Relaxed JEDEC Late Command Training [Disabled]

Modified bios not needed for this, correct? Can just set these manually?

edit: I see the last two things now, understood.
