So I think I may have ended up buying the wrong ram for my build. I'm using a Sabertooth Z77 motherboard, and this is the RAM I bought.
PC3-12800 4GX2 Intel MXP ready
It doesn't seem to go in all the way, and I don't want to force it. Did I end up buying the wrong ram?
And if anyone could point out what I do look for in sizes and compatibility for RAM?
