It's great to see how individual memory stacks up against the competition under stock configurations, but we're also going to show how it compares when overclocked. With performance in mind, we're going to compare the maximum overclocked results of the various DDR2 DIMMs we've tested in the past which are listed below. Remember, just because memory is clocked fast doesn't mean it's the best thing for a computer. Timings are also important, and getting the right ratio of both is the real key to performance based overclocking!

It's a shame that the Intel Pentium D 840 test system maxes out so quickly, still the Buffalo Technology FSX1000D2C-K2G memory is not the first DIMM tested that makes it too 1020 MHz. With a faster system, I think the Buffalo FSX1000D2C-K2G could fly...

2GB of lightning fast DDR2-1000!

If you think current generation systems require a lot of memory bandwidth, you haven't see anything yet. With the industry going towards parallelism, memory manufacturers have to ramp up memory speeds in order to keep up with the demand of multi-core processors.

For the modern Intel Pentium D system, there isn't much better than Buffalo's 2GB FireStix FSX1000D2C-K2G DDR2 memory. It's not just lightning fast, with 2GB it's also ready for memory intensive applications/games like Battlefield 2 or Microsoft's Windows Vista.

Customer service is often an afterthought when buying computer components but it's great to know that Buffalo backs its products with a lifetime warranty. Should you run into trouble, Buffalo also has a 1-800 number for users to call which is easier to use than having to email them for service.

Saying the Buffalo FireStix FSX1000D2C-K2G memory is fast seems like an understatement and it performs as quickly as previously tested DDR2-1000 class memory from Patriot Memory. In every benchmark from 3DMark05 to Quake 4 and SiSoft Sandra, the Buffalo Technology PC2-8000 DDR2-1000 memory kept up with the likes of Corsair, Crucial and Patriot; pretty good company if you ask me.

In terms of overclocking the Buffalo FireStix FSX1000D2C-K2G is pretty quick hitting a top speed of 1020 MHz with 5-5-5 memory timings. For the low latency crowd, the memory can run at 925 MHz with 3-4-4 timings, the latter is great news for users looking for memory to use with AMD Socket AM2 Athlon64 processors's.

The Buffalo FireStix FSX1000D2C-K2G memory kit retails for about $419 USD ($460CDN, £226GBP), and can be found at Monarch Computers and NewEgg. If you need to get some quick DDR2, it's worth weighing the benefits of the Buffalo FireStix FSX1000D2C-K2G.
