In this section we will explore the area around the CPU socket, which has a number of interesting gizmos.
At edge of the board we find an 8-pin EPS and 4-pin ATX connector. These should supply extreme amounts of current to the CPU without catastrophic melting.
We also have additional 6-pin PCIe and floppy plugs to aid PCIe and memory OC.
The heatsinks used on the Maximus V Extreme are relatively modest unlike the liquid cooled ThermoFusion design found on the Formula. Still, they should suffice as the heat output from the PCH and MOSFETs of Ivy Bridge Z77 platform isn't as monstrous as its Sandy Bridge-E X79 counterpart.
We find a no-nonsense 8+4 phase (CPU and Uncore) VRM design once we take off the heatsinks.
The Maximus V Extreme uses TrenchMOS FETs, with NXP 7030AL on the high end and NXP 5030AL on the low side,. Each pair is capable of 68A @ 25C, more than enough for any kind of overclocking.
Like on recent boards, ASUS's industry leading DIGI+ VRMs are capable of very precise digital control and monitoring of the MOSFETs to prevent blue smoke incidents during intense loads.
Moving on to the action packed section of the board, we get fifteen voltage probe points for various overclocking parameters, the all-important Power/Reset button and a perpetually helpful PORT-80 diagnostic LED. A jumper selector marked "LN2 mode" enables extra BIOS options and profiles and a slow mode selector switch is there for the extreme tweaker. A set of DIP switches controls PCIe slot on/off for troubleshooting and red-black pinouts are for the VGA Hotwire (voltage sensors and variable resistors) cables.
Another new feature on the Maximus V Extreme is "VGA Power Control", allowing the motherboard to directly interface with up to four sets of I2C controllers on the graphics cards to adjust voltages, OCP, LLCs and switching frequencies.
So, stay tuned on VR-Zone for the next Vaseline filled LN2 episode of the Maximus V Extreme review!
