Alright you guys asked for a tutorial, here is a tutorial,

Only problem is that its in Russian.

I cannot even find the 7771 he used as reference. LOL.

[adaseb]

Yeah but you got a general idea of how it works now at least.

[QuintLeo]

It took a lot of digging but I did eventually find a working link to The Stilt bios for download - last year.
No idea if it's still up or not though - the link I found refered back to his thread on the LiteCoin forums but I don't think there was a FORWARD link anywhere to the working download site.

 I made a point of downloading ALL of them at that time, and tossed them on a USB flash drive - if I can figure out how to get a FTP server working through my current firewall appliance I'll look into putting them up for download.

This is a bit confusing. The bios i got from gpuz indicates elpida, also says elpida when you open it at vbe7. Now i open the rom with hex editor its all 01 which tells me its hynix.

Your BIOS has usually 2 types of straps for both HYNIX and ELPIDA memory. Just modify the one you are using.

Yeah would be good, would help out a bunch of people here.

This is a bit confusing. The bios i got from gpuz indicates elpida, also says elpida when you open it at vbe7. Now i open the rom with hex editor its all 01 which tells me its hynix.

That number is simply used to label each particular set of timings, AFAIK the number used is arbitrary.

Some card BIOSes include timings for multiple types of memory, it allows a GPU manufacturer to switch VRAM used in production batches based on price/availability/etc... without making any other changes.

An Elpida timing could potentially be 00, 01, 02 (or possibly even 03) it depends on how many sets of timings the BIOS has.

Personally, when I 'm hunting for timings in hex I search for 33 20 00 00 00 00 to find all the timings regardless of what numbering scheme they used.

[Bojcha]

I wonder is there anything for 280x with hynix BFR memory.
Seems no one done for those.

Thanks for clarifying. Now i get 78sol/s after editing the hex. What is that timing in hex?

Yeah thats the most I can get with ELPIDA GPUs. The memory is just worse then HYNIX.

temp goes up also. before at 65 sol/s its 56C now at 78sol/s its 61C same core clock and voltage.

I just followed the instructions on that russian tutorial.

However, after I modified the bios, and tried to open it with VBE7 program (just to verify it was valid) it says the checksum is wrong and won't open it. Then I actually flashed it to the card, and it showed the new information to be blank on the card like it normally says old info was Taithti PRO or whatnot, and new info says Taithti Pro.. But this time it was all blank for the new info, so I pussed out and put back the original bios on it. In never rebooted the system.

Is that normal for the new info fields to be blank, I wouldn't think so. Thanks.

Here's what ATiwinflash output on the modified bios.
C:\Users\1a\Desktop\biosstuff\atiflash_274>ATIFLASH.EXE -f -p 0 0mod.ROM
Old DeviceID: 679A
New DeviceID: 0
Old Product Name: TAHITI PRO GDDR5 3GB BIOS
New Product Name:
Old BIOS Version: 015.025.000.099.000000
New BIOS Version:
Flash type: GD25Q10TCP
20000/20000h bytes programmed
20000/20000h bytes verified

Restart System To Complete VBIOS Update.

After that I reverted to original.

I followed the same steps. Mine did open on vbe7. Then I edited the voltage, core clocks and fan control on vbe7, saved it to a new file name then flash it. Card accepted it. Editing in vbe7 corrected the checksum.

Hrmm.... not sure what I could have done wrong.. Guess will try again.

NEvermind, I'm an idiot, I thought vbe7 didn't open it, and was still showing the previous cards bios I opened but it did actually load it, and once I saved it with vbe7 it corrected the checksum. The part about using vbe7 is not present in the tutorial though. Should be added.

on that card it didn't change. 70 HS/s. Not sure....Probably doing something dumb.

 Not my work, I think this is the link I found last year to download them from.

Just ask ... will always mod for you 

Download https://drive.google.com/open?id=0B6R3UoULhg3cbWYwVlYzNmUtSGc

Modded with straps from 1250MHz --> 1375MHz , 1500MHz  (1500MHz Should kick ass - ~80+ sols/sec)


p.s.1 - Flash with AtiFlash.exe from command prompt,  atiflash -f -p X rom_name.rom  , x = card number given by atiflash -i

p.s.2 - This is not some "Dirty hack" with timing tables from some totally other card, but timing table from same card's bios, for that specific memory (BFR).
