Are the clocks applied?
They are! The overclock is 100% via BIOS mod

Why not? Undervolt for better power consumption, every GPU can be OC for better hashrate.

I will reformulate the question: Have you tried overclocking that video card with good results? Because I have read that it wont make any different

Zcash is core intensive you don't need there memory OC.

Maybe core overclocking?

THank you!

Yeah, the voltages should be less than 900mV with these core clocks. The main problem would be Anorak's bios, it's not very good, he just copy and paste straps from 1500 and up. You can do it by yourself with stock bios it's better, but still not very good.

You are right i guess, because it's not stable anymore. Currently i change core voltage to 66, core clock to 1225 and memory clock to 2000 and want to see this for couple hours.
If this configuration failed i want to restore to it's original rom and start all over again in strapping 1750.
Do you have any specific rom for my cards?
Regards.

1065MHz with 1+V? You can run those clocks at 800mV. I would run it at least with 1100Mhz, for stability it can be like 850-900mV with no problems even if the card is not very good.
