Win a 2GB Crucial memory kit

One of the best ways to upgrade any PC is to give it more memory. A couple of new DIMMs can turn almost any old donkey into a thoroughbred racehorse. Plus, it's easy to do, and you can reap the benefits immediately.

We're giving you the chance not just to upgrade your system to 1GB, but to beef it up with a massive 2GB of fast PC3200 of memory, ensuring that you have enough to run the most demanding applications. The four lucky winners will each get a memory upgrade that's guaranteed to work in their specific system — even if it was custom-built, Crucial's memory-matching database will ensure the perfect fit. If you have any doubt about what memory you need, you can use the Crucial System Scanner to tell you. It really is that easy.

And with 2GB you have the option of running the full 2GB as single-channel memory, or running the two DIMMs in parallel to get that extra boost.

So whether you're upgrading a mediocre Christmas present, getting ready for Vista or getting your PC ready for the rigours of dual-core, 64-bit, virtual machine computing (or just the latest games), you need to enter this competition.
