    Yo, it's in the OP
    If you need some more in-depth How-To -> Please ask guys with Polaris uArch GPUs.

    Polaris Bios Editor v. 1.4
    -> https://github.com/caa82437/PolarisBiosEditor

    UPD.
    Seems like you need to make your BIOS back Up then edit/save and Flash this baby in !
    it is similar to Fiji BIOS editor IMO

    fake gtx 750ti
    Hi guys,

    I'm new here. I need help please.. I 've bought a fake gtx 750ti with 4gb ram. After google and video searching, i found out that my vcard has gts 450 chip and had only 1gb vram. i tried all possible vcard bioses at techpowerup using my bios chip flasher and also tried the bioses on youtube by the user Philscomputerlab but I have no luck. The vcard bios is stable but it crashes if it jumps greater than 1GB. My PC reads my vcard ram as 4GB while the real vram is only 1GB as I manually check the chips in the card and reading the datasheets.

    My question is, is it possible to hex edit the vbios so that my PC, instead of reading fake 4GB vram, will read the real vram which is 1GB?. Please help me.. I will upload the bios guys. PLease help me I don't know how to hexedit.. PLeaseeeee....

    Here's the vbios file.. https://mega.nz/#!J001HaBb!8TiEgphLHjDHrUAcpKLV_opBVF-EUNlj4z5v_6rryHU
