Both my Maximus Formula and Extreme have extra probes on the NB/SB etc, with the Extreme having 3 extra thermal probes you can place yourselfs. My P5K Premium don't have these sensors. I think it's just a X38 chipset function?
I have also had the 2 x 2GB OCZ DDR3-1600 EB Kit that cost almost £600!! :eek: , which refuse to boot at the advertised speed.. :( so I RMAed it and got the 1800 CellShock. Absolutely loving it!!:D
Note that the Maximus has a 2 phase Northbridge power controller, whereas the Formula, and in fact all my other motherboards, has only single phase. It might have contributed!! :D :up:
