I doubt that 5700 will stay stable at 90w giving 54mhs ok lets say it is stable at 90w giving you.
Enough proof?

Here's modded bios if hepls you,
but remember, just 1500MHz strap+underclock+undervoltage+power limit+fan speed are modified) memory freq is stock (1750MHz). Just add 10MHz+to memory (1750 to 1760) and it starts to give some invalid shares, and/maybe random fails of cards, showing 0.000MH for failed card.
That's why I prefear to lose 0.2-0.3MH per card and achieve stability (no fucking restarts or locks) and no invalid shares.
