Evo lik iz thread-a mi je poslao PM... šta reći, čovek je car.
Hi omnik,
In fact, to do the modifications of the bios image is not that complicated, but to get the idea you have to read the thread from the beginning
(also the link to the russian guide).
Anyway, I'm not using hexedit anymore, instead of hexedit I did a simple linux script (oneliner) to do the modifications. When the voltage values are replaced by linux sed I'm doing a quick open/save in VBE7. To run these cards at 1060MHz, the 1050mV core voltage should be enough, but it depends on the GPU ASIC quality. If You have some cards below 70-75% ASIC You have to go with the 1075mV version.
So, I did this two version for You.
