my vegas 64 liquid didn't want to go below 875mv (850 in gpu-z) with soc clock 1107 (needed for mem clock 1100). It results in 19.6khs
For 1140 mem clock (1199 soc clock) they need 900mv (875 in gpu-z). It results in 20.2khs
It doesn't depend on gpu clock - only soc clock is setting min required voltage.
vega 56 ref samsung with stock bios is happily mines with 825mv (800 in gpu-z) with 940 mem clock resulting 19.5khs
That's not necessarily true... SOC and core appear to share power lines (which explains their relationship in bios/ppt) - I've seen many cases where a specific voltage which didn't seem to be enough for 1107 SOC was suddenly fine when I dropped core low enough. Ethash was a great algo to test this on, as you can run Vegas at p0 w/ no performance effect. CN-trtl is similar in this regard - while we may not be able to go all the way down to 850 Mhz cclock, 1100 is perfectly performant, and leaves a lot of power headroom for SOC/IF, resulting in lower required voltages.
In short, it's really the combination of core clock + SOC clock which determines your voltage requirement.
yes, thanks.
