Help with UEFI Tools section replacement

Hi all,

I try to replace a compressed section containing some values that I try to change into my gigabyte bios.
I’ve extracted body (with UEFI tools and UBU) and had modified the wished Hex values.
I replace body with UEFI tools, everything seems ok, and I save the modded bios.

Once into AMIBCP, to check if it’s done, nothing has changed. All values are as before.
But, if I extract bios body structure, the Hex values have been modified.

Did it work ?
Did I do something wrong ?

it worked !

now I can change Edram to more than 2100mhz and it’s fully functionnal (just tried to 2200mhz).
