UPGRADE THE PROCESSOR
Why you should upgrade your PC’S processor
Your computer’s speed and longevity are largely defined by the abilities of its processor (CPU), so it’s logical to assume that upgrading it with a powerful new one – such as from Intel’s new i9 range – would result in a massive boost. Sadly, it’s not that simple. Most motherboards are designed to work with specific processors and are usually compatible with only a handful of models, which limits your PC’S upgrade potential. One way around this is to upgrade the motherboard and processor at the same time (see opposite).
Then there’s the upgrade procedure itself. Replacing a laptop’s CPU is all but impossible, but even for desktop PCS, it isn’t as straightforward as upgrading memory or storage – you’ll need to wrestle with heatsinks, thermal paste and more besides. It’s a delicate process that carries a high chance of damaging your PC, so you’ll need to judge whether you think it’s worthwhile.
Buying a new processor
CPU-Z can tell you which processors are compatible with your motherboard. Click the CPU tab, then note the manufacturer listed under Name (Intel or AMD) and the socket number listed under Package. Next, click the Mainboard tab and note down the details listed under Chipset and Southbridge. Now visit hardware company Gigabyte’s website ( www. snipca.com/28991). Select the correct model from the Choose Socket and Choose Chipset dropdown menus, then click Search to see a list of processors that are compatible with your motherboard.
We recommend buying the most powerful processor you can afford. Higher clock speeds (in GHZ) and a larger L3 cache (in MB) mean more power, but the number of processor cores is also important – the more the better. Bear in mind that powerful processors need more mains power, so check the maximum load (in watts) of your PC’S power-supply unit (PSU) by opening your PC’S case and reading the label on the PSU – it’s the big metal box with the mains cable plugged into it.
Processors vary quite a lot in price. You can sometimes find older Intel and AMD processors for around £50, but newer, more powerful models can cost upwards of £250. Unless your new CPU comes with thermal paste, you’ll also need to buy this for around £5 online.
How to install a new processor
The procedure varies depending on your computer and the type of processor you’re upgrading. Broadly, though, you’ll need to find the processor socket, which is usually near the memory slots on the motherboard. You also need to remove the heatsink and any other cooling devices – such as a fan – to access the existing CPU. Be very careful, because you’re handling extremely sensitive components.
Before you replace your processor, take a photo showing how your current CPU sits in its socket, so you can use it for reference later. Then grip the old CPU and pull it out firmly.
Insert your new processor (pictured right), using your photo to help position it and ensure it’s the same way round as the old one. Avoid touching the connectors beneath. When it’s seated correctly, press it gently in place but don’t force it. Once it’s in, apply a small amount of thermal paste to the top of the CPU, then replace the heatsink and any fans as they were before.
