How to Build the Ultimate Gaming PC, Step by Step
Build It
Step 1: Prep the Case
The first thing we do to get our red Cooler Master HAF 922 ready for the build is to install the brass motherboard standoffs in the case (image A). A few standoffs are already installed, but you’ll have to install the rest. To do this, carefully hold your motherboard above the case and eyeball where to install mounts. Ideally, one standoff should be installed for each mounting hole in your motherboard. Hand-tighten them first, and once they’re in place, use a pair of pliers or a small wrench to tighten them down. Torque them down enough so they don’t back off when you need to remove the motherboard.

Now, install the I/O shield (image B). These rectangular metal panels cover your I/O ports such as USB, LAN, and keyboard, and are matched to your motherboard. Your board should have come with one in the box. For some strange reason, some cases come with I/O shields already in place. If this is the case in your… erm… case, you’ll need to remove this first and pound yours in. Use the back of your screwdriver to pop it out by hitting from the outside of the case, and then pop your I/O shield in place.
Step 2: Install the CPU

(Image A)
Since our case does not have a removable motherboard tray, we’re going to add several components with the mobo out of the case. With the motherboard on a flat surface, unclip the arm that holds the CPU load plate in place and flip back the arm (image A). This will lift the load plate out of the way. You’ll now need to remove the protective plastic tab that covers the pins in the socket. The one Asus uses requires that you remove it from one side first (image B). Others may need you to grasp it on both sides. Do not throw this plastic tab away! If you need to return the board to the store or manufacturer, they will not accept it without the tab in place. Do not touch any of the gold contacts in the socket, either—bending one may kill the motherboard.

Install the CPU by holding it parallel to the socket and carefully lowering it in place (image C). Notice the two notches in the socket that should line up with the two notches in the CPU. With the chip in place, fold the load plate in place and lock the arm.
How We Overclocked a Core i5-760 to 4GHz
There are wild rumors that Intel may lock down overclocking on its new budget chips next year. Yes, you may be clock-blocked!
Thankfully, with existing chips there’s no such barrier. So, to eke the most out of the budget quad in our gaming build, we decided to overclock it from its stock 2.8GHz all the way to 4GHz. Ah, now you understand why we spent the extra ducats on our Cooler Master Hyper 212+ over the stock heatsink fan.
So, how did we accomplish the overclock? The first step was to make the correct voltage tweaks. Interestingly, our Core i5-760 part didn’t take too much crazy voltage to achieve a stable 4GHz. We set the CPU’s voltage to 1.25, the IMC voltage to 1.15, DRAM voltage to 1.36, left the CPU PLL voltage on “auto,” and set the PCH voltage to 1.0875. (If you’re faint of heart, you may want to avoid voltage tweaks and just run the simple automatic overclock available in the board’s BIOS.)
We then set the CPU ratio down one click from its default of 21 to 20 and cranked the block up to 200MHz from its stock 133MHz. Our target for the DRAM was a conservative 1,200MHz and the QPI was set for 6,407MHz.
Once configured, we stress-tested our rig overnight using our proprietary Maximum PC Lab stress test and a top-secret Intel stress-testing utility, and had no issues whatsoever.
Step 3: Install the Heatsink
Our CPU came with a stock Intel cooler. It’s fine at stock speeds, but we chose the Core i5-760 with overclocking in mind. To accommodate the increased heat, we chose to use Cooler Master’s Hyper 212+. At $30, it yields performance that rivals some heatsinks more than twice its price.

(Image A)
The first step in installing this cooler is to mount the backplate on the board. You’ll be putting a screw in through the front of the board and then tightening a nut to it on the back of the board (image A)—a special tool comes with the heatsink to aid with tightening the nut. Once the backplate is in place, we’ll carefully apply some thermal compound (it comes with the heatsink) on the CPU’s heat spreader (image B). We just place a few BB-size bits on the chip and use the tip of the syringe to spread it evenly around the metal top.

(Image B)
The heatsink ships with the fan attached. You’ll need to remove the fan by gently bending the clips that grip the heatsink. The Hyper 212+ works with multiple sockets and the X-shaped adapter comes from the factory set for LGA775. To set it for LGA1156, you need to pull up each of the spring-mounted screws and slide them to the middle hole. Now, take the adapter and slip it inside the heatsink. Next, screw down the heatsink using a cross-star pattern (image C).

(Image C)
Once the heatsink is in place, you need to also install the fan. But before you do that, put some thought into the airflow of your case. Do you want the air to be sucked into or blown out of the rear? You can easily reverse the flow by dismounting the case fan and heatsink fan. The industry standard is to exhaust air out through the rear fan, but there is a good argument for sucking in cool, exterior air and blowing it over the CPU first. With the HAF 922, you can run either way.

(Image D)
Let’s finish the installation by popping the fan assembly onto the heatsink (image D). Finally, plug the fan into the header marked “CPU.”
Step 4: Install RAM
The P55 chipset and Core i5 feature dual-channel memory support. That means you need to have RAM that’s the same size and speed, and install it in the correct RAM slots. The most common memory-installation mistake is to put the RAM in the wrong slots, thereby configuring the board for single-channel. The second-most common mistake is putting the memory in the inner pair of slots. That works for LGA775 and AM3 boards, but do so on a Core ix and it probably won’t boot.

(Image A)

(Image B)
On this board, we put the RAM in the two slots shown in image A. When you know where to install your RAM, match the notch in the RAM with the notch in the slot and gently push it into place with pressure on the outer corners until it locks in place (image B). You usually hear a click, but sometimes you may not. Make sure the arms that hold the RAM are securely in place, as well.
Step 5: Install the Motherboard
With our RAM, CPU, and heatsink in place, it’s time to install the motherboard. Not that you didn’t follow our instructions, but you did install the I/O shield, right? If you haven’t, now is a good time to do it. This Asus board uses a snag-less design, but many other boards continue to use cheap metal shields. Make sure the little metal arms in the I/O shield are bent upward, so the motherboard can be installed without the arms blocking the ports. Once the shield is in place, bend the metal fingers until they make contact with the top of the metal cage that holds the ports.

(Image A)
OK, now gently lower the mobo into place (image A). We installed nine motherboard standoffs in the case. All nine should line up with the mounting holes in the motherboard. If you installed nine standoffs and you only see room for eight screws, this means you have one of the standoffs installed in the wrong place. That means the bare metal standoff could be poking into a spot on the board, which could potentially short something out. In this case, you will need to remove the board and locate the one standoff that is in the wrong spot.

(Image B)
Back to the installation. Tighten down all the screws to hold the board in place (image B). The spacing should be fine but if you find that it is difficult to install add-in cards, you may have to loosen the screws and move the board away from the back of the case. The board won’t move much, but the tiny bit of wiggle room may be just enough to allow you to install the cards.
