Well seems that the luck is not with me again, got new paste, opened laptop, took a picture before removing the cooler. Checked the type of the chip and BAAAM - 1,8V. Ordering adapter now :(
Found datasheet thou.DATASHEET

@Lost_N_BIOS While I am waiting for a 1.8v adapter to arrive could you tell me which 2 bytes you are changing and in which var I will try to change it with linux in efivars folder?

Sorry I missed you so many times @bat_malin - Sorry about the FPT stuff, you cannot use that since this is AMD system.
Vars edit is only helpful to disable Intel related locks, so you can use FPT, so dump of vars or edit vars wont matter here. The two bytes I mentioned is the actual BIOS edit, not vars edit (that would be 2-4 bytes changing, if this was Intel)

Yes, that is XM25QU64A 1.6-1.8V chip, use Software 1.38 from package here - http://s000.tinyupload.com/index.php?fil...125571740490142
Also, here is other package with many software versions, in case you need later - http://s000.tinyupload.com/index.php?fil...213094641136166

You may be able to use flashrom from linux, here is guide, see if you can dump chip, if so, then you can probably program as well (only valid if system is bootable still, I think it is)
Flashrom also works, here is Linux/Ubuntu method/guide - [GUIDE] The Beginners Guide to Using a CH341A SPI Programmer/Flasher (With Pictures!)
And here is Windows version someone made (post 510) - [Guide] Using CH341A-based programmer to flash SPI EEPROM (34)
And here in "Annex" Section at end, another possible method, similar to first link above (ignore 32MB/Asus info)
