Vega 56 to 64 Bios Mod
so i flashed that 64 bios on my 56 and it' seems to work fine. no new CUs but hopefully power limit should now be at 64s level. HBM seems to be further overclockable also (which is kinda strange...). you can find some quick results here:
repeated that test with fire strike:
has to be said, that the 56 results were preformed on the slave bios, as the 64 bios was still on the master. what's the difference? im not quite sure. state 6 & 7 frequencies and voltages seem to be the same.
the overclocked and undervolted results seem to scale a bit better in fire strike.
the main difference between the bioses seems to me, that you can clock the HBM to 1100 MHz on the 64 bios, where it crashes over 960 MHz on the 56 bios. probably something to do with an internal voltage controller that you can't change in wattman or other tools.
as for power comparisons between the two bios'es ... i hope i can preforme those later this week if i can get a grip of a new ampere-meter.
as for the bios tweak. im not sure if it's worth it, as you can get most of the performance gains on the 56 bios while doing an signifcant undervolt and slightly OCing. doing so, you can cap the fan speeds at reasonable levels and won't be much distracted while game sound is running.
