So I'm bad luck then, I have 4 gigabyte vega 56. Overclocking SOC to 1200 not working stable, miner stops working, miner freezes, pc freezes. Tried setting those numbers from C0,D4,01 to 38,C1,01 (for 1,15Ghz) but no luck SOC stays 1200 (1999). Increased Voltage for both GPU and memory, it works like stable, get about 2% more h/s but get about 12% compute error, which I never seen before.


In the end I really dont even care about the extra 50h but I'm curious why the fck it does not work on Gigabytes.


Identical cards. Works like a charm on Sapphires on high mhz and low voltages. Does not work at all on Gigabytes.

On GB cards I can get the SoC to work on 1200mhz with my own reg files but then I am limited to 950mv minimum.

What gives ?

Did you use Gigabyte BIOS files?



No' used generic AMD but they should be all exactly the same. Will try one tosay just to be sure.

What limits your own reg file to 950mv? 


To be honest - I dont know. Just wont work below that. It's a mystery to me why Rednows works on some cards as well.


I can tell what 30% of the entries in PowerPlay do. Rest is still a mystery and never had the time to really dig into it.

If I get the time I might start to compare Rednows differences in the reg.
