Motherboard Layout Continued
On the
back I/O panel are the Dual OTES exhaust system, where two 40mm fans
draw heat away from the heatsinks that sit on the MOSFET's. The top
left corner screw hole is covered by the duct and requires the duct to
be removed for proper installation. Underneath the two 40mm fans are
the PS2 keyboard and mouse ports, 4 USB, and 1 RJ45 jack for Gigabit
connection. You won't see the serial and parallel ports. Although I do
have an old printer that still uses parallel connection, it's time I
upgrade anyway. Notice anything else different about the back I/O?
There are no audio ports. This is because Abit includes a daughter card
called AudioMax specifically for sound. Abit claims that with sound on
a separate card, noise interference will be greatly reduced. The
AudioMax comes with SPDIF In/Out as well as 6 channel support. It's
rather strange to see the use of lower end Realtek ALC658 as the audio
codec when there is the higher ALC850. I wouldn't say Realtek is high
quality sound, but ALC850 should be the very least used. On the
daughter card, there are the front I/O connectors, in case you want to
extend your audio ports to the front of the case. I'm not too sure if I
like the position of the audio slot way up at the top of the PCI slots.
If the enthusiast wanted to connect an audio cable, it might get in the
way of large heatsinks. I'll be using a separate sound card.
As
for the rest of the usual IEEE1394 and USB ports, those are included on
PCI brackets and connected to the appropriate ports shown earlier.
Moving along, there are diagnostic LED's at the lower right corner, a
great feature to have. If the system doesn't boot, you'll see why and
be able to figure out the problem. Next to the diagnostic LED's is the
IEEE1394 port. To the right of the floppy connector is the CMOS jumper.
Throughout all testing and overclocking, I didn't have to clear CMOS a
single time. At the bottom right corner of the board are the front
connections. The pins are color coded and allow for easy installation
without referring to the manual.
The
CPU socket is clear of tall capacitors. Installing large heatsinks,
like the Thermalright XP-120, won't be a problem. Unlike other Abit
motherboards that have the uGuru chip located near the bottom portion
of the motherboard, the Fatal1ty has the chip at the very top. It's not
a big deal and doesn't make a difference.
