Virtual-Hideout posted a review on the HyperX PC3-11000 DDR3 Memory Kit from Kingston

This is where Kingston Technology has come to answer the call. One of those kits could very well be the Hyper X KHX11000D3LLK2/2G Dual Channel Kits. It's based on their newest performance Hyper X DDR3 series intended for the upscale and more serious enthusiast who want to tap in to their processor's unseen performance. At 1375MHz, it operates at a frequency previous DDR2 modules just couldn't quite achieve mainly due to power requirements and related heat causing too much instability. Have a look at Kingston's latest signature Hyper X DDR3 1375MHz modules.
