Topic: Hacked Modified Memory Strap BIOS Database for ZEC MINING! - page 15. (Read 78516 times)

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.

Will try at home, thank you!

Yes, it is.

I have stock, dual bios button to switch, possible to switch power still on?
use silent army windows  4x 280 250 sol

Linux optiminer
what driver are you using for linux, amd  16.40 / 15.12  also add the video user like install silent army? 

Try resetting your cards on stock. On optiminer I can reach 150sol/s on stock 280x. 

Hi, I like to try this, anyone info for Sapphire R9 280x Vapor-x  3x elpida  bios 15.042   1x hynix bios 015.041

https://docs.google.com/spreadsheets/d/1odJXgWbHUcIS9fAxaXB-nPD8WWH1sBdd_XBOe3F3jo0/edit?pref=2&pli=1#gid=0

not sure what to use

Does anyone have something for Sapphire 280x dual-x?

Is that for me? Just want to make sure

imo if it's already been modded then start with your backup up bios and copy it to bios 2, then copy a lower frequency strap to all of the higher frequencies.  See how it works, then try another one till you get one you like -- or try some of the straps on here

I have a bunch of old 7950's with elpida memory that I found a decent strap for, but oddly one of the sapphire Vaporx gpus had Hynix in it and I couldn't get it to work any better than the Elpida.  Also the same Bios won't work in all the sapphire 7950 versions,  but the same strap will work in each bios. It's really not as hard as it looks, just play around with it. ... those Ruskies explained it pretty well on that website

I may play around with it some more if more straps pop up -- with claymore 5.0 my 7950's elpida memory are running around 100+sols, which isn't too bad for an ancient gpu.  my RX 480's are only around 120+ sols

I've even been baking my old dead 7950's in the oven to bring them back to life  -- so far I baked 4 and 2 of them started hashing again -- have to bake about 10 more -- rofl

adaseb,

here are the strings from the ORIGINAL ROM for that GPU from the techpowerup.com database:

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:


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

No I deleted it.

It never worked however with Windows.

Yes it did. Most likely due to luck of pool also. Pool found more blocks during the claymore run. Its not as concrete as that.

@adaseb, do you still have optiminer zip file? no longer available at his github? can you upload it? will give it a try. thanks

At least i could try, cant guarantee its working though^^

I donate ZEC.

Here you go http://www.filedropper.com/club3dmodded
If you like you can donate me some ZEC ^^: t1TkccsX7TxuezkP9sHGX9hJ7scwD1Ag2Pa

What speeds is everyone getting with Claymore 5? Mine are peaking at 120H/s with Hynix mem

Which is pretty much my 470 and R9 290 speeds

Do you confirm then that there's a 27% difference in the amount of coins obtained?

Because if there's a delta like that, it means that there's the need to make further studies in this matter, to understand the real gains due client/server side hashrate, shares and so on.
