[Problem] Where is info of onboard ram stored on bios file? ASUS

Hi
I have changed my onboard ram chips inorder to increase capacity
but my laptop still shows old ic chips and capacity.
I have tried many things for example deleting nvram memeryconfig section of bios extreacted from bios ic and nothing changed
even renaming supported modules in bios file which there are some modules name which my old and new models are included in it too, but laptop didn’t boot up
I don’t know what else I could do to make laptop identify new chips.
model: asus k513eqn
ram chips: from M471A5244CB0 to M471A1G44AB0
Thanks in advance

Open chassis and disconnect main battery (30m), boot up and clear/load/reset factory keys TPM/Secure Boot, other than NVRAM only traces on current OS install.

I appreciate your response. I have done that, I have even shorted jrst2401 and jrst2402 on main board, only way I kniw is editing bios file
