Speed up your PC and get a Windows Experience Index score of 5.9. Part Two

When Microsoft set the processor benchmark for its Windows Experience Index, it set it high. To score a 5.9 here you’ll need a processor that would give a world chess champion a run for their cerebral money. The quick and easy answer to the 5.9 score
question is a quad-core processor. In which case even a basic Intel Core 2 Quad Q6600 will do the trick and costs around £130. Be aware that this runs on a 1,066MHz FSB so by choosing this, you’ll find it difficult to get a 5.9 memory score. If you want that perfect 5.9 consider the Q9300, which does use the magical 1,333MHz FSB and retails for around £165.

Extreme measures

We have seen the odd system running dual-core Intel processors achieve a 5.9, however these are either the very expensive Extreme Editions or have been overclocked. According to our tests, you’d need to push the processor to at least 3.2GHz, and more likely 3.4GHz, to nose past the 5.9 level. For many, the good news is that if you have an Intel i965-based motherboard, it should be able to take a quad-core processor, though a BIOS update would likely be required.

For AMD systems the advice is very similar. You’ll require a quad-core processor which is made up from its Phenom range. AMD also does a triplecore Phenom, which we haven’t been able to directly test, but are reliably informed won’t quite score 5.9. So you’ll want to opt for at least the AMD Phenom X4 9550, which retails for around £120. These processors use the newer AM2 socket. Before you upgrade you’ll need to check your motherboard is an AM2 board and that it can handle the quad-core processor.

Install a new processor

1 OUT WITH THE OLD

If you’re upgrading, you’ll need to remove the old processor and fan. This is good, as it means you’ll learn how the heatsink and cooler fit together. On AMD systems this is via a lever system; with Intel systems there are four corner screws.

2 SOCKET TO THEM

On both Intel and AMD systems you’ll find a level running down the side. This needs to be pulled up to release the processor. There are markings on the processor itself that align with those on the socket; carefully align these and place the processor.

3 GREASY LOVER

On Intel systems lower the fixing bracket, then for both systems secure the fixing arm in place. Add four small blobs of thermal
grease on top of the processor and reattach the cooling fan, not forgetting to attach its power lead.
