From the screen it seems that they upped the bus to 140MHz and the CPU multiplier was under 40x, so probabily untouched. I doubt that they moved the NB multiplier and probabily they only lowered the ram multiplier. In this situation the scaling is about linear with a few percent less... 300MHz on 5.5GHz is 5%... I find implausible an extra 5% increase just fiddling with multipliers... I think that default multipliers are already choosen to maximize performance... The only hypothesis is that they upped the bus and lowered the ram and left turbo and XFR activated. They took the screen at idle, where the multiplier was jumping between default (36x) and in the very instant of the screen was 37.5x or so (i don't remember) but during the run could have also jumped to 39-41x due to the very low temperature granted by the LN2... 140x39 is 5460...
