My HP HP Pavilion G7-2330sr work with only ddr3-1600 memory. But it supports ddr3-1866. I have read datasheet "BIOS and KernelDeveloper’s Guide (BKDG) for AMD Family 15h Models 10h-1Fh Processors". I have AMD a10-5750m APU and bought DDR3-1866 memory, which works only as 1600 (( I am a system programmer and have read many forums, papers on BIOS mod. I extracted last BIOS v. f.2a for my notebook and got 57E9EEE9-EB7D-4453-BBF7-6C181FD09027.rom. I dissasembled it in IDA. But I don't know what I must search and replace. Please help me!!!!
