AWARD BIOS for Gigabyte 8ipe1000mk

[de6ir]

I want to modify the AWARD BIOS for Gigabyte 8ipe1000mk. Specifically, I just want to expand the memory frequency multiplier options. There are 3 options available right now. 1.33, 1.66 and 2.0 .
I want to add 1.75 to the options. Or just replace 1.33 with 1.75 .
Alternatively, being able to set the memory frequency manually can also do the job.

Motherboard Make/Model: Gigabyte 8ipe1000mk
Bios Version: f14
Link To Official Bios: http://download.gigabyte.eu/FileList/BIO...mk_f14.exe

I've tried using Award Bios Editor, but it doesn't help.

A modded bios or any suggestion for modifying this bios is welcome.
