Why do you guys use ufile and not mediafire. Ufile always archives these files and then no one can download them mediafire seems to work for years.............
Did u include rst module can u still do that and what about mei module..... I dont think ur using the latest one......... Still the system is faster with ur bios but no one else can download it now because ufile already archived ur bios you guys use some very bad file sharing sites on this forum other older motherboards they are using ufile as well. Im studying this all myself anyway so I can do this all myself looks fairly simple to do but takes a lot of research to learn it all but the guides exist now which they didnt years ago when I tried to look into bios editing so thats nice. Mei driver and module does provide some nvme performance boost fernando has posted benches in his guides so there is a reason to look into it.

I’m sorry for any inconvenience, I have updated the link using Mediafire. Pls check it.

sorry update mod bios for new bios up to thanks>>>>>>>>>>>>> https://download.msi.com/bos_exe/mb/7B12v1B2.zip

Update and integrate [Chipset menu] into the 7B12v1x version. Please check it.
Sorry for the late update.

Updated the unlocked HPET option and various uCode for everyone to choose.

(I just tested the dsanke SET, please feel free to contact me if you faced any problem)

Nice work @ritizen , very interesting to see the Cinebench R15 scores with those 3 microcodes.
