PC Modding Malaysia has posted a review on the OCZ PC2-8000 Titanium Alpha VX2 2x1GB memory

Overall, OCZ redefines DDR2 overclocking with the return of Voltage eXtreme series. Being the first DDR2 to bear the VX2 tag, the PC2-8000 Titanium Alpha kit is designed for overclockers. Physically, the PC2-8000 VX2 looked like it came from out of space and you will definitely love if you like to pimp your rig. Based on the infamous Micron D9GMH memory ICs, these modules is rated at 500MHz CL4-4-4-15 It works as advertised and our benchmark results prove that DDR1000 does bring a slight improvement over DDR800. Although we did not hit the magic 600MHz mark, we did manage clock it up to 562MHz at CL5 but it was not "Prime" stable. For 24/7 operation, we found 550MHz at CL5 to be the maximum overclock as the modules showed excellent stability during our 11 hours stress test on our setup. Priced at about $489 / RM1800, the PC2-8000 VX2 kit is quite pricey but you will be covered up to 2.52V though. If you are looking at getting a new 2GB DDR2 kit for your high-end AM2 or Conroe setup with plans of overclocking and overvolting, the OCZ PC2-8000 Titanium Alpha VX2 2GB kit is worth checking out, provided if you have a 490 bucks budget just for the RAM. However when you crank it up to 2.5V, you can be rest assured that OCZ will cover you down the road!
