I bought an MSI P67A-G43 mobo. I am planning on installing an i5 2500k or something better next summer. For now, I have an i3 2100 to put in there. Would that work?
For memory, I have G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800). Will this work? I know the i3 2100 uses 1066/1333 mhz ram, but the memory I bought should work right? Whats the difference between what I bought and PC3 10666 memory?
Yes. The memory is supported by your motherboard. Even if your CPU uses 1066/1333 mhz, the RAM itself should run at 1333mhz speed. You can check your BIOS to see the memory profile to see the timing/speed.
