Asus P8H67-M EVO: Physical Details

The Asus P8H67-M EVO is a more professional-looking board, with all its capacitors being solid-state and the presence of VRM heatsinks around the socket. It also has an 8-pin EPS12V power connector which is a bit overkill seeing as the initial LGA1155 processors have TDPs of 95W or less and overclocking is a non-factor on H67 boards. The same goes for the board's 8+2 phase power design.

The P8H67-M EVO supports four DDR3 DIMMs, two SATA 6 Gbps drives, four SATA 3 Gbps drives, and two PCI-E 16x cards (one runs at 4x). It has three fan headers, but only the two near the CMOS battery are controllable.

Cable management should be a little bit better with the Asus board. The 6 Gbps SATA ports are on their side and the 8-pin power connector is closer to the center of the board rather than the corner making it easier to access. The VRM heatsinks which resemble crystal formations are only 25 mm tall at their highest point so they won't with most third party heatsinks.

With DisplayPort and VGA connectors, the P8H67-M EVO has a more impressive variety of display outputs than the DH67BL.

Asus P8H67-M EVO: BIOS

The P8H67-M EVO is the first Asus board we've used featuring their new EFI BIOS with a graphical user interface, a welcome addition if only because it's less of an eyesore and allows the use of a mouse. It has two modes, Basic, which provides a similar experience to using Asus' desktop tweaking utilities, and Advanced, which is more or less the same as gray/blue screen we've gotten used to over the decades, only a lot easier to look at.

BIOS: AI Tweaker screen.

BIOS Summary: Asus P8H67-M EVO
BLCK Frequency 80.0 to 300.0 MHz
CPU Voltage
+/- 0.635V in 0.005V increments
VCCIO Voltage
0.80V to 1.70V in 0.01V increments

PCH Voltage 0.80V to 1.145V in 0.01V increments (1.05V default)
iGPU Max. Frequency
1100 to 3000 MHz in 50 MHz increments
iGPU Voltage
+/- 0.635V in 0.005V increments
Memory Frequency
800, 1066, 1333, 1600, 1866, 2133, 2400 MHz
DRAM Voltage 1.20 to 2.20V in 0.01V increments
Memory Timing Control Intermediate
Fan Control Q-Fan options: Upper/Lower Temperature, Fan Max./Min. Duty Cycle ( both CPU & Chassis Fan)

The P8H67 BIOS offers more extensive voltage control, though it isn't really useful due to the aforementioned inherent overclocking limitations of the H67 chipset. Its only real advantages are a wider range of memory controls and fully customizable control of two of the board's three fan headers.
