1000 MHz FSB and Beyond

If you thought it was an accomplishment to reach 1000 MHz FSB with the use of the PC4000 memory we tested in this article we published early this year, you areĀ in for a pleasantĀ surprize!

The top 3 memory makers have found ways to push their memory beyond PC4000 speeds (500 DDR). Today, we are looking at kits available at PC4400 and PC4300, which is DDR550 and DDR533 respectively.

When topped out at DDR550, that brings the FSB of an Intel Pentium 4 system up to 1100 MHz! This is a TON of bandwidth available for your OC'd P4 CPU. In fact, probably more than you'll ever need. But at the very least, you will know that you are going to reach the limits of your CPU long before you reach that of the memory, when paired up with one of the above products.

So why pick up some "PC4400" when you can try to do what they do, and overclock the memory that is already available to you? Well there are a couple reasons. First of all, when buying from Corsair, Kingston, and OCZ, you will be covered by warranty, in some cases even if you push beyond THEIR specs. If you've overclocked memory before, you know how volatile it can be. Why not spend the extra bucks and get something that is guaranteed to be stable for all the time you have it?

Basically the main point is, you are guaranteed that these products will reach their stated levels. If you were to buy standard Hynix ram, you do NOT get that guarantee, and if you happen to fry it, you're left with nothing.

The Looks

It's no secret that one of the reasons some of us want this ram is for looks. Fancy heatspreaders (and in some cases, activity LEDs!) set these products ahead of every other memory product. They can really put the finishing touches on your modified rig!

Both OCZ and Kingston use nicer clips than Corsair. On top of that, they look a lot better in my opinion. The deep blue HyperX sticks would look sweet in an all-blue setup. And the OCZ copper heat spreaders are absolutely brilliant, and would match up perfectly with a nice big copper heatsink on the CPU. The Corsair is lacking in the looks department, with cheap looking spring clips, and flat black heat spreaders. Corsair is also available in silver.

Corsair does carry a product line with activity LED's, but not in the speeds we're looking at today. They may become available in the future, and they would definitely set the Corsair ahead of both Kingston and OCZ in terms of looks!

Now we'll have a closer look at each set, in alphabetical order:
