At a first glance the
ASUS Maximus V Extreme looks very good with its harmonic design. Once again the
ROG-colors - red, black and white - suite
nicely and together with the black PCB it becomes a beautiful product. The
layout itself is well thought and there is for example plenty of space around
the CPU socket to install even todays largest CPU coolers. The fact that there
are SATA connector which have been angled by 90 degrees
allow an easy installation of oversized graphics cards.
The ASUS Maximus V Extreme comes with a
digital 8+4+2 phase power design. The CPU gets eight phases, the iGPU can rely
on four phases and the memory gets a stable current supply from two individual
pahses. Furthermore ASUS equips this board with their so called "Black Metallic
Chokes". These can resist temperatures ranging from -70°C to +125°C. This makes
the power desing even better for extreme overclocking where extremely low
temperatures around the CPU socket can be reached.
Totally you'll find four DIMM-slots on the
Maximus V Extreme. Officially supported are DDR3
2800 (OC), 2666 (OC), 2600(OC), 2400 (OC), 2200 (OC), 2133 (OC), 2000 (OC), 1866 (OC), 1600, 1333
and 1066 MHz. There is engough space between the DIMM-slots and the CPU socket which
means that you wont encounter compatibility problems with big coolers even when you choose to install RAM with big heatspreaders.
Also supported are Xtreme Memory Profiles (XMP) in version 1.3.
Maximus V Extreme the southbridge as well as the PLX chip, which can be found
between CPU socket and the first PCI-Express x16 slot, are being cooled by
passiv cooling blocks, which have been connected via a heatpipe. For the current
converters we see a very similar picture. There are also two passive cooling
elements connected via a heatpipe. In fact, the PLX chip is always an
interesting feature. In this case ASUS chose to put a PLX PEX8747 PCI Express
3.0 bridge chip onto the board. This chip is able to multiply the 16 lanes,
which come from the CPU, by two an therefore provied 32 lanes. As long as you
don't use more than two graphics card 16 lanes are sufficient but once you run a
setup with three or four graphics cards you will need at least 24 or 32 lanes.
