Some explanation about my bios unlock maker :

On the bios setup screen ,you can see seven buttons and it will link to a tab when we click it on and button will become to yellow and get the focus. The idea of my unlock maker is let button link to a new tab that are contained more useful hidden options.

For example :

This is old contents what you can see under the OC button.


This is new contents under the OC button after it modifed.
(Advanced tab)

Now i think guys already understand the work principium with my before unlock makers.  Now I will make a little changes on my new unlock maker(ERP74070C 2K231201).

New change logo:

1.  This time i connect the chipset tab below to OC button.

(chipsei tab)

And because this platfrom(H670) seems support memory overlcock ,but unfortunately it can't adjust manually memory parameters on unlocked options.
So ,if we would like to overclock memory we can only use the stock options "Memory profile" & "Memory Voltage Adjustment Control" to get a little memory performance.

But we already conected chipset tab to OC button ,so there there have no place to put these two options ,so i spent a long time and research the feasible solutions.
Finally i decide inject them to chipset tab >> System Agent (SA) Configuration and let all profiles(such as XMP Profile 1 ,XMP Profile 2...etc) items appear . Below is what i changed.

Before modify.

After modified

Tips : You can find other options related in memory on  chipset tab >> System Agent (SA) Configuration >>Memory Configuration.

2. What changes under the Feature button?? This time i don't connect any tabs to Feature button because i want to stay sub-memu : PCI Subsystem Settings because
it included some important options ,such as "Above 4G Decoding" , "Re-Size BAR Support".

This time i inject Advanced tab to stock  Feature button. If it's success then you can see a new tab name Advanced under the Feature button.
