Upgrade Your CPU

The ﬁ rst step in any CPU upgrade is to choose the right processor for your motherboard. The safest way to do

this is to visit your mobo maker’s website and look for a list of CPUs the manufacturer has certiﬁ ed. If you’re feel-

ing frisky, you can cruise the Internet to see if people are running CPUs beyond what the mobo maker has tested,

but we don’t recommend this tack for newbies. The second step is to update your motherboard BIOS; if you don’t,

there’s a chance your machine won’t boot with the new processor. Only then are you ready to begin.

Now that the old

heatsink is off,

simply ﬂ ip up the

arm that locks the CPU

in place, remove the

old CPU, and put it in

the CPU cookie jar. If

you’d like to use it in

another machine, place

it on a clean, static-free

surface. Once you’ve

installed the new CPU,

put the old one in that

packaging until you

need it again.

If you’re using your old heatsink (you

made sure it’s capable of cooling your

newer, hotter CPU, right?), you need

to clean off all the old thermal paste using

a lint-free cloth soaked in isopropyl rubbing

alcohol. We recommend the 99 percent stuff

you get at the pharmacy, but we’ve never had

problems with the 70 percent grocery-store

variety, either. Now, place a BB-size dab of

thermal paste in the center of the mounted

CPU. When you lock down the heatsink, the

pressure should spread the thermal paste

over the entire surface of the CPU.

Socket 478, 754, and 939 Processors

Examine the notches on your

new CPU to make sure it’s

properly aligned with the sock-

et. Socket 478 Intel chips and Socket

754/939 AMD chips have an arrow that

should match up with the arrow on the

CPU socket. Carefully insert the chip into

the open socket. There should be very

slight resistance going in; anything more

means you either have a bent pin on the

new CPU or you have it lined up wrong.

If you suspect something’s gone awry,

stand down immediately and take a look!

Reattach the bracket for

the heatsink, plug in the fan,

and ﬁ re up that bad boy!

The last step

in this installa-

tion is to verify

that your CPU is

running at the cor-

rect speed. Enter

the BIOS settings

screen by holding

down the F2 or the

DEL key during

boot. When you’re

in, check the values

for the CPU multi-

plier and front-side

bus speed.

LGA775 Processors

To install an

LGA775 proc, hold

the CPU with your

thumb and foreﬁ nger directly

over the socket. Lower the

CPU straight onto the socket.

Don’t drop one side and then

the other, and don’t slide

the CPU over the top of the

socket. Either of these actions

has the potential to kill the

motherboard. Push the lock-

ing bracket down to secure

the CPU in place.

Remove the old CPU

heatsink by first prying

off the heatsink retention

module. This will vary from

one heatsink to another, so

you might want to consult

the manufacturer’s web site

before you dismantle your

PC. Once you’ve released

the heatsink, carefully twist

it left and right until the ther-

mal paste works loose. If the

heatsink is really stuck, fire up the machine and run a CPU-inten-

sive application to heat up the processor. The heat will soften the

paste, and then you can shut it down and attack it again.

Socket 939 motherboard

For photography purposes, several different motherboards were used. We strongly discourage any attempt to use a

Socket 939 CPU in a Socket A mobo.
