Summary: Awesome memory, the best I've ever had in many ways. Simply took the old memory sticks out and popped these in and Windows 7 Home Premium immediately recognized the new memory. Also, this memory is low profile which means that it doesn't have oversized heat spreaders that can create problems when trying to install bulky after-market (non-stock) CPU coolers.
Summary: Hi i used this with my newest custom build as my after market CPU cooler extends over my RAM slots on my motherboard, because of this i had to go with "lower heatsink" Memory cards. I looked for weeks for RAM that had no heatsinks on them, stumbled accross this Corsair Vengeance 8GB (2x4GB) DDR3 1600 MHz (PC3 12800) Desktop Memory... 2months later having a blue screen error which translated to a RAM problem.
