Bytesector posted a review on the Kingston HyperX PC2-7200 Memory

Kingston has been quietly developing memory in a back room somewhere and has now launched DDR2 memory with speeds up to 900MHz. This must be pretty amazing for a company that is known for their ValueRAM line to those who aren't hardware enthusiasts. Usually when I think of memory, it's usually OCZ or Corsair that come to mind, but today, I had the opportunity to take a look at Kingston's PC2-7200 2GB memory kit and I must say, they are offering performance that the competition hasn't yet been able to touch. With more than 8GB/s of buffered bandwidth and 6.6GB/s of unbuffered bandwidth, this memory definately proved to be what we all expected from DDR2 memory!
