Corsair Vengeance Pro DDR3 2400MHz Memory Review
 

"Any rig worth it's salt will have some fast DDR3 installed but MHz is not the only key to a good performer. Timings and compatibility and reliability matter more to the end user than speed. There is no point in some DIMM modules that cause system crashes but is ultra-fast, but slow and solid memory is not desirable either. The only alternative, despite how obvious it sounds is fast and reliable memory."
