Hacked Modified Memory Strap BIOS Database for ZEC MINING!

Best straps for a R9 290 card? 

With elpida memory

[igor44283]

At least i could try, cant guarantee its working though^^
http://www.filedropper.com/7950modded

Is that for me? Just want to make sure

Yes, it is.

Will try at home, thank you!

I tried and hashing speed is the same as before, can you please check if the timings were saved?
I would do it myself, but tried for 2h to understand the hex editing thing and got nothing.

Try 1375 MHz mem-clock

Tried, I actually get lower hash, at around 90, instead of 95.
Maybe the strap I asked you to add is bad? It is the first one posted in the OP, for Hynix, which I have.

L.E. I think I did it, I took the chance and took the gigabyte 7950 modified rom from the OP, and flashed on my MSI. Now I have 100h/s stock. Time to up the clocks and see where this goes.

Glad to hear you got it working. I am not really experienced at this kind of thing, just had some free time and thought i could try. Sorry it didnt help.

Hi,
Is there any ways to get memory type under Linux ?
I've dumped the bios, and my card is that one : https://www.techpowerup.com/vgabios/161932/msi-r9270-2048-131211
Of course, the goal is to find the best timing

[adaseb]

With the Claymore V5, you should get very close to 120Sol/s however you will need the clocks to run at 1050-1100 for engine core and around 1550-1600mhz for memory clock. Most GPUs have stability problems at those clocks however. Elpida are much worse then Hynix.

adaseb, please look at and comment on my posts above.  Which strap would you change or move and why?
5 straps starting at 1250 -> 1750

[frozn0000]

I have 4x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB that I have been using mining zcash.  Is it just a matter of flashing this rom in the via atiflash that is in the original post?  That's it?

Post your ROM and i'll mod it to the Hynix AFR I posted in the main post.

You sure you got Hynix and not Elpida?

Depends, check which memory type you got with each of those GPUs.

Use GPU-Z. If you got Hynix for all of them, flash with the Gigabyte 7970 Hynix ROM posted above.

Do one GPU at a time in case something fails.

I have 4x Gigabyte 3GB all with GDDR5 (Elipida).  GPU Clock 1100MHZ - Memory 1500MHZ

I have 1x VisionTek 3GB with GDDR5 (Samsung).  GPU Clock 1050MHZ - Memory 1500MHZ

Thanks!

For your Gigabyte 280x try

https://mega.nz/#!K9l3jDCT!z8tmV57GkU6JEHxgaZhkOdCMMS09XF9a0z5YJfyyZJg

Its slightly undervolted, so increase voltage if you have instability and slowly increase to 1100Mhz/ 1575Mhz from 1000/1500Mhz stock.

Elipida is always slower and that card only runs at 108Sol/s for me @ 1000/1500. Try 1100/1575Mhz and if its stable you might get up to 120Sol/s.


For your Samsung, I got nothing.

Yeah, like I wrote:  Hynix AFR memory:

Thanks

adaseb,

This is the existing modified ROM from a Sapphire Dual-X HD 7970 3G OC with boost GPU, Hynix AFR memory,

I have attempted to follow the Russian video and I get this far:



After finding all five of the 77 71 hex incidences I copy the strings between them, and immediately after the last one to give me:

Code:

3320000000008CC5583170550F10251F17050048C40022CC1C00640B14204A8900A000000120120D202532202614

I note that the last three strings are identical as this is a modded ROM already.  Which of these strings would you change, and why?

Please help,
Thanks

I actually have no idea which string does what. I just copied these timings from that overclock website but what they did to modify them I have no clue.

[fury420]

I ran across the weirdest BIOS yesterday...
It's an XFX 280 and has timings for Hynix AFR, BFR and Elpida.... but the timing table is TINY!

Each one has only four timings with transitions at 400, 800, 1250 and 1625

Unsure if the card was AFR or BFR so modded both, getting peaks just over 110 sol

I have flashed the rom you mentioned above with atiflash to one of the Gigabyte (Elipida) cards.  I am getting 95 - 97 H/s.  When you say "Try 1100/1575Mhz" do you mean modify the rom itself with VBE7.0.0.7b.exe to match those numbers, save it, and reflash the card with the new file or do you mean set those settings in MSI Afterburner?  Forgive me for my lack of knowledge this whole mining thing is new to me and I am trying to learn.  Thank you!  Anything I can do to the bat?  Here is how it looks now and thanks!

You can do it in Afterburner since you are allowed to overclock, you just can't underclock there you would have to use VBE7.

Hi adaseb Loving your support for modding gpus. Do you have anything for MSI 280x ?

[kaltar]

Ok, here is a stupid question and i'm almost embarrassed to ask, but how do you copy the straps into Hex Workshop, i found the correct line etc, i copy the strap to the clipboard but it won't allow me to paste it in the hex workshop. i don't want to have to retype that long line.

Just flash these straps at your own risk, if you have no idea what you are doing, then leave this thread now. I assume NO RESPONSIBILITY if you brick your GPU, messed up your memory chips, etc. YOU HAVE TO MAKE SURE YOU HAVE THE CORRECT MEMORY. ELPIDA WONT WORK WITH HYNIX STRAPS.
