Corsair kicks ass because they maintain their build quality, always keep up with the latest technologies and have managed to stay competitive while maintaining a positive reputation in the business.
I have been using Corsair Memory for years. I have used Dominator Series modules on numerous gaming rigs with zero issues. I even used their cheaper Value Ram for a machine intended for basic use. What has remained a constant through it all is the consistency in quality I have experienced. The stuff just works and is backed by a great warranty. Nuff said...
