I have an Asus P5L-MX motherboard and have wanted to upgrade the CPU for some time. Right now, I have a single-core Intel Celeron D with a Prescott core. I’ve pretty much maxed out the overclocking possibilities (I’ve gone from a stock 2.66GHz clock to 3.47GHz) and now I want to replace it with something better.
Andrew, your motherboard’s 945 chipset doesn’t support quad-cores. You can, however, drop in a decent dual-core, like the Core 2 Duo E6700, which you can find online for around $130. It’s going to be a fairly substantial upgrade to the machine you have, without breaking the bank. If the E6700 is too spendy, your board also supports some other Core 2 Duo chips—the E4300 through E6700. You’ll almost certainly need to update your BIOS to take advantage of any dual-core, though. For the full list of CPUs supported by the P5L-MX, go
. Asus’s support page offers BIOS downloads and a flashing utility.
We wouldn’t spend any more money than this on a machine this old, though—for about $250, you can buy a decent quad-core Phenom or Athlon II and a new motherboard, while still using your other old components.
