Hello all, new PC builder here. Built a system awhile ago that I currently have an EVGA P55V motherboard sitting in my PC with 2 Corsair XMS3 RAM Chips in it at the moment (DDR3 1600 PC312800). I recently came across a pair of Kingston KTA-MP1066/4G RAM chips and wondered if I could use 2 of them to go from 4gb ram to 8gb ram or if they would be incompatible with my motherboard.

Current motherboard: EVGA P55V 120-LF-E651-TR LGA 1156 Intel P55 Micro ATX Intel Motherboard

Current RAM: CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX4GX3M2A1600C9

New RAM: Kingston 4GB DDR3 1066 (PC3 8500) ECC Mac Memory Module w/ Thermal Sensor Model KTA-MP1066/4G

Any response would be greatly appreciated, and thank you for taking the time to have a look at this.

The Kingston is ECC? If so it will not work in a non ECC motherboard. ECC memory is generally only found in servers although for some reason Apple decided to use it in Macs.
