Topic: Hacked Modified Memory Strap BIOS Database for ZEC MINING! (Read 78472 times)

I just wanted to say thank you so much ive been looking everywhere for this! your a life saver!

This is my bios, please mod.
HD7950-DC2T-3GD5-V2
Thank you!

I didnt see anything in the OP about 380 and 380x. I am using modified bios for ETH currently but would like to know the best settings and if I should change bios for zcash.

Thanks

I can't figure out how to paste a line in hex editor, i select the field that i want to change, but i cannot paste into it.
I've started changing  number by number but i have to do this like 14 times for like 50 digits number, and i just couldnt do it.

i also would like to try the gigabyte bios with elpida memory, see if it might work on my saphire with elpida memory, but all the download links are down.

edit:

I worked it out, if anyone needs help with editing a bios with hex editor, i can do it for you.

Hi,

Anyone can help me bios mod my Sapphire HD 7970 VaporX 3GB with memshifts ?

Thanks !

Can somebody help me to modify the timings of this bios for MSI 290 Gaming with Hynix memory?

Bios: https://ufile.io/dnfxu

Thanks

Dont use another bioses, just modified your own. If you have Tahiti, there was a link in first post, to overclock.net site. Download there Tahiti-HynixMemoryTimingsPatch.zip and patch timings from you own bios.

I'm thrown for a loop here guys, can someone point out "Where" I'm being an idiot (I know I'm being one lol)

I have a R280X that "loooks" like this except the XFX is on the far left of the front instead of being in the middle. Same color everything though.

On the back sticker, and when recognized by my computer it says "R280X" however the sticker on the back said "2GB" not 3GB" which is all I've seen listed I googled for R280X 2GB and had no luck finding the one I have ..

Anyways, when I'm hashing I'm getting 90-95 sol/second on ZCash using NH Legacy Miner .... I read another article I thought I bookmarked but I found this here saying they are getting 300 sol/s out of their card(s) by flashing them ..

Do I have a model this doesn't work with ? Since it seems most of the links are talking about 3GB R280X and I appear to have a 2GB R280X

If I could actually triple my hash rate I'd be as happy as a pig rolling around in s%#t ...

I just thought I'd ask before I go about and possibly brick my card. In case the model I have does not work ... Still confused about the 2GB vs 3 GB deal. If it wasnt for that I would already be figuring out which package applied to my card and flashing it. First read this a few days ago and checked on and off the last few days looking for more info about my 2 GB model but don't seem to be able to find it. It really looks like the R7770 but it's coming upp as R280X on my miner and on the sticker on the back of the card.


EDITED : JUST LOOKED, SAYS R7 200  not 280X on my miner/tweak software

1) Hey guys i just want to know, if i have 275sol/s on 7950(1000/1250) and 300sol/s on 280x(1030/1500) i wont see any big difference with the modded bios right?

2) i want to drop the voltage on a Gigabyte 7950 from to 1.05v which number do i have to change on the hex editor?

There is no problem. You can use that.

Is it safe to use ATIWinflash to flash BIOS ? How do you flash bios ?
I have MSI R9 280X 3GB

I don't remember exactly, but it was like RX 480 if you undervolt it.

anyway crazy i will never buy such adapter for that price
in my computer chop here  they sell  22'' used monitor for only 10$ more lol, and the monitor are actually still very good

what about power consumption?
thank you for your information.

I had R9 380, it's like 285. For XMR I've got 560H/s in stock and 650H/s with Nerdralph bios.

Anyone use PowerColor TurboDuo R9 285 2GB GDDR5 OC?  Or Just R9 285 any brand.
Can you share your hashrate for zcash and monero mining.
Thanks

I would be careful with these adapters I bought this exact one and all was good for a few weeks than the card which was using this adapter on burnt out

Hello. Can someone help me with a Stilt modded BIOS for Sapphire  R9 280 which has Elpida memories ?
Also one for Sapphire R9 280x Elpida, Sappire R9 280x Hynix, Gigabyte HD 7970 Hynix ,Gigabyte 7970 Elpida, Gigabyte R9 280x Hynix , Gigabyte R9 280x Elpida. Please.

Thank you for clarifying the issue.
Yeah, the HDMI seems to be more future-proof. I've seen ppl soldering some resistors into the D-sub adapter )
