Hello. I have laptop with motherboard Clevo W670SFQ (Intel HM86) with Nvidia 840M. Could anybody help me with modding UEFI-BIOS. Need to have options for DRAM (timings and etc).

Manufacture of laptop is DEXP and they do not have any support page, I think. Also, I should tell, that I have have CH341A programmer, so I can do experiments.
UPD:
I made visible all options, what I wanted. First, I used AMIBCP 4.53. For Chipset options I used this: http://kulasov.blogspot.com/2013/08/over…book-n56vm.html
Now I can overclock DRAM 
But now new questions: I heard about modded (adapted from 940MX) VBIOS for Nvidia 840M with no limit +135mhz overclock and unlimited TDP, but I can not find this, maybe You know?
And is it possible to use Haswell microcode-bug for unlimit ratio for overclocking i7 4700MQ with chipset HM86?
UPD: No options to change DRAM Voltage?
