HyperX KHX8000D2 DDR2 1000MHz (PC2-8000) and HyperX KHX8500D2 DDR2 1066MHz (PC2-8500) are unbuffered modules with Latency Timings of 5-5-5-15-1 and 2.2 Volts operation.

This will be welcome news if you're shifting to the AMD AM2 platform which uses DDR2 memory rather than old-school DDR. The integrated memory controller in Athlon 64 thrives on fast memory but it's easy to confuse the clock generator which runs at 200MHz, so "funny" speeds can cause problems.

We anticipate that PC2-8000 will be the bullet proof version, while PC2-8500 will keep the overclocking lunatic fringe happy.

The suggested retail price for a single 512MB module is £90 inc VAT for both the KHX8000D2 and the KHX8500D2.

Students of maths will deduce that a 1GB dual channel kit of two modules costs £180. If you have your sights set on bigger things in the shape of 1GB modules, you'll have to settle for the KHX8000D2 at £175 or a 2GB dual channel kit at £350. ®
