Wrong description for this item
I have a new i7 920 quad core 2.66 system with the x58 chipset. Great system. Wanted to add 2gb to the 6gb xms (3x2) set it has. This module is not, i repeat, not 10666 1333ghz memory! This model is 10600 1333ghz memory & wil not work with the other 6gb 10666 xms tri channel set(3x2) i as well bought from tigerdirect. The description needs to be changed to 10600 memory so other people don't waste time, money, & shipping charges for this module. If you can only use 10666 memory, you can't use this.It says right on the package when you get it. 10600 1333ghz memory & that's what it is. I'm sure it will work beautifully with other 10600 memory.
