PC Modding Malaysia has posted a Kingston HyperX DDR2 PC6000 review

Being the fasted DDR2 modules we have tested up to date, I have to admit that these HyperX DDR2 modules proved that they are the fastest. With the ability to do 3-3-3 timings at DDR667 is no joke and Kingston proved that they are back with some kickass DDR2 memory. Although we did not meet the rated speed, which is DDR750, it was mainly because our test setup. I'm sure with the latest NF4 or 955 chipset, the HyperX PC6000 will eventually fly at high speeds we can only imagine of. However, we can only confirm once we have geared up with the required motherboard. If you're looking for a fast DDR2 memory for your system, HyperX DDR2 PC6000 has everything to power your need for speed.
