Hi, I have a MB of Packardbell S3810 (Is the same that S3811 with 16Gb Ram). This MB can to have 16 GB of Ram, but is limited with 8Gb of Ram. I need to unlocked that restriction.
MB has this inscription: ACER INC. MBU5H090010480060CEK01
U02D1048011784 PC H57D02P8 1.0 6KSMH.
BIOS P01-A4:
https://drive.google.com/file/d/1EyKp7F6...sp=sharing
Someone can unlocked this bios for use 4 modules of 4gb of ram?
I extracted BIOS with this result:
MD5 BIOSORIGINAL
49045673f85ff010583368dcdc755864
CRC32 BIOSORIGINAL
2393EA67
I used AMIBCP_v3.37 for to see BIOS table, but I dont understand how unlock ram.

Explain exactly what happens when you try to boot with 4x4GB DIMMs.

MB only recognized 8gb. With CMD (wmic memphysical get MaxCapacity, MemoryDevices) MB only 8388608Mb and 4 slots. I dont buy any module of 4gb of RAM yet. Actually 4 modules of 2Gb RAM. Packard bell límited this MB to 8gb of RAM.

I'm not interested in purely theoretical work.

MB is the same that S3811. And S3811 has 16Gb RAM. BIOS is blocked for read only 8Gb RAM.
Can you can say me what parameters I have to change?

Have you any S3811? What processor is currently installed within?
