Fatal1ty Story
Who knew that at age 19, I would be a World Champion PC gamer. When I was 13, I actually
played competitive billiards in professional tournaments and won four or ve games o guys
who played at the highest level. I actually thought of making a career of it, but at that young
age situations change rapidly. Because I’ve been blessed with great hand-eye coordination and
a grasp of mathematics (an important element in video gaming) I gravitated to that activity.
GOING PRO
I started professional gaming in 1999 when I entered the CPL (Cyberathlete Professional
League) tournament in Dallas and won $4,000 for coming in third place. Emerging as one
of the top players in the United States, a company interested in sponsoring me ew me to
Sweden to compete against the top 12 players in the world. I won 18 straight games, lost
none, and took rst place, becoming the number one ranked Quake III player in the world
in the process. Two months later I followed that success by traveling to Dallas and defending
my title as the world’s best Quake III player, winning the $40,000 grand prize. From there
I entered competitions all over the world, including Singapore, Korea, Germany, Australia,
Holland and Brazil in addition to Los Angeles, New York and St. Louis.
WINNING STREAK
I was excited to showcase my true gaming skills when defending my title as CPL
Champion of the year at the CPL Winter 2001 because I would be competing in a totally
dierent rst person shooter (fps) game, Alien vs. Predator II. I won that competition and
walked away with a new car. e next year I won the same title playing Unreal Tournament
2003, becoming the only three-time CPL champion of the year. And I did it playing a
different game each year, something no one else has ever done and a feat of which I am
extremely proud.
At QuakeCon 2002, I faced o against my rival ZeRo4 in one of the most highly
anticipated matches of the year, winning in a 14 to (-1) killer victory. Competing at Quakecon
2004, I became the World’s 1st Doom3 Champion by defeating Daler in a series of very
challenging matches and earning $25,000 for the victory.
Since then Fatal1ty has traveled the globe to compete against the best in the world, winning
prizes and acclaim, including the 2005 CPL World Tour Championship in New York City for
a $150,000 rst place triumph. In August 2007, Johnathan was awarded the rst ever Lifetime
Achievement Award in the four year history of the eSports-Award for “showing exceptional
sportsmanship, taking part in shaping eSports into what it is today and for being the prime
representative of this young sport. He has become the gurehead for eSports worldwide”.
LIVIN’ LARGE
Since my rst big tournament wins, I have been a “Professional Cyberathlete”, traveling the
world and livin’ large with lots of International media coverage on outlets such as MTV,
ESPN and a 60 Minutes segment on CBS to name only a few. It's unreal - it's crazy. I’m living
a dream by playing video games for a living. I’ve always been athletic and took sports like
hockey and football very seriously, working out and training hard. is discipline helps me
become a better gamer and my drive to be the best has opened the doors necessary to become
a professional.
A DREAM
Now, another dream is being realized – building the ultimate gaming computer, made
up of the best parts under my own brand. Quality hardware makes a huge difference in
competitions…a couple more frames per second and everything gets really nice. It’s all about
getting the computer processing faster and allowing more uid movement around the maps.
My vision for Fatal1ty hardware is to allow gamers to focus on the game without worrying
about their equipment, something I’ve preached since I began competing. I don’t want to
worry about my equipment. I want to be there – over and done with - so I can focus on
the game. I want it to be the fastest and most stable computer equipment on the face of the
planet, so quality is what Fatal1ty Brand products represent.

Chapter 2 Installation
is is a Mini-ITX form factor motherboard. Before you install the motherboard,
study the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
Make sure to unplug the power cord before installing or removing the motherboard.
•
Failure to do so may cause physical injuries to you and damages to motherboard
components.
In order to avoid damage from static electricity to the motherboard’s components,
•
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
Hold components by the edges and do not touch the ICs.
•
Whenever you uninstall any components, place them on a grounded anti-static pad or
•
in the bag that comes with the components.
When placing screws to secure the motherboard to the chassis, please do not over-
•
tighten the screws! Doing so may damage the motherboard.

2.2 Installing the CPU Fan and Heatsink
Aer you install the CPU into this motherboard, it is necessary to install a larger
heatsink and cooling fan to dissipate heat. You also need to spray thermal grease
between the CPU and the heatsink to improve heat dissipation. Make sure that the
CPU and the heatsink are securely fastened and in good contact with each other.
Please turn o the power or remove the power cord before changing a CPU or heatsink.

2.3 Installing Memory Modules (DIMM)
is motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel conguration, you always need to install identical (the same
brand, speed , size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one memory
module installed.
3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

2.5 Jumpers Setup
e illustration shows how jumpers are setup. When the jumper cap is placed on
the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper
is “Open”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”
when a jumper cap is placed on these 2 pins.
Clear CMOS Jumper
(CLRMOS1)
(see p.1, No. 16)
CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short pin2 and pin3 on CLRMOS1 for 5 seconds. However, please do not clear the
CMOS right aer you update the BIOS. If you need to clear the CMOS when you
just nish updating the BIOS, you must boot up the system rst, and then shut it
down before you do the clear-CMOS action. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed.
