How much do you ideally undervolt with CryptoDredge when mining Lyra2Rev2 ?.. Some people go as low as 65 % - 70 %, claiming it's the most efficient, while the
majority prefers 75% - 80%. Of course the lower you go on voltage, you can squeeze more Core overclocking from your cards, but with the proviso that
too much OC causes lots of bad shares, so I would be very interested if anyone found an optimal MSI configuration for this particular miner
You simply cannot compare PL % settings of different cards.
Percentages don't tell shit, because it is relative to the TDP set in the BIOS of the particular card.
Card A has TDP 250W (average 1080Ti with AC) and card B has TDP of 280W (1080Ti with LC).
70% means 175W for card A and 196W for card B.
It's obvious that card B will perform faster (if the clock/voltage curve is similar, but that also differs adding more complexity to the problem)
The same logic also applies for Core and Mem clock offsets. +100 means nothing, because 0% GPU clock can be anywhere between 1500 and 2000MHz.
So please stop comparing them among different cards, makes no sense.
You have to compare the exact clocks.
