Link to latest ?

 

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

 

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

Pick one of mine, then adjust properly for Your GPU.
Test for Stability etc. then Edit & Save then Flash and Game

Tmod_HBM_Neo_560.1356v.rom
Tmod_HBM_Neo_1356v.rom

Edit with new Fury BIOS Editor -> Adjusted (every GPU is little diff.)

Sorry to bother you but I was wondering if you had Fury X FX6 bios without the -37.5mV to it? Rather have no offset.... but rather have +25mV to vcore and vmem if possible.

- Thanks

 

Just edit BIOS in Editor (Give 1.225v)
For FuryX LC is better to ask @Fox2232

 

I add 1.3v in BIOS Editor but it really is 1.265(ish) actual voltage. Goes down to 1.22(ish) under load. That 37.5mV is taking away 50-75mhz from my max OC. Yes, I want those 1-2fps. LOL

I'll ask him. TY

 

Hi there. I'm not sure if this thread is still active, but I could really, really use some help. I have an Amethyst card, S7100X (M390X) with separate VBIOS. Amethyst is, from what I know, a sub architecture of Tonga. I do have a SPI Flasher, as well as familiarity with ATI Flash, but I cannot hex edit to save my life. Worse, HawaiiBiosReader and TongaBiosReader read the values wrong from my VBIOS.

All I want is an unlock, as well as a reduce of the TDP on certain situations (Battery, Small Battery)

Would anyone be willing to help me? I've been looking around quite a bit and would overwhelmingly appreciate it.

Hi!
Hate to bother, but I need some help please.
I've just bought an Radeon R9 NANO card (Hynix HBM). What is the best Tmod BIOS for it?
Thanks.
