[CWWK W680] Memory Settings in BIOS ?

Hello,

I am writing to kindly request a custom BIOS version for my CWWK W680 motherboard to allow higher memory speed options.

For your reference, here are the results from my testing:

The latest BIOS tagged "mem4200" works great with 128GB of RAM (4 x 32GB) running at 4200 MHz.

With other BIOS versions, the system cannot POST (55 ERROR CODE) when using 4 sticks of RAM, but it works perfectly at 4800 MHz when using only 2 sticks.

Given that 4800 MHz works stably with 2 sticks, I would like to attempt booting at higher frequencies or fine-tuning the memory parameters with 4 sticks.

Could you please provide a custom BIOS binary with the RAM frequency settings and Memory Overclocking options fully unlocked in BIOS?
Or give me some tips to boot with 128GB @4800mhz 

My motherboard details:

Model: CWWK W680
Current BIOS Version: 2026.1.15-CW-W680-3L-NAS-YV292-T15-ES_50_VMD_2R_mem4200-CWLOGO.iso

(so exact model recommended by your end https://bbs.x86pi.com/thread?topicId=18428)

Only one SSD put in.

Thank you in advance for your assistance and support.
