So, i just bought bf4 and i only have 4gb of ram, when i play on ultra settings the ram usage is as high as 92%, which causes a bit of a lag. Im certain it cannot be my graphic card since it's a gtx 680! My options are limited in selecting ram. Since my cpu cooler is huge and it blocks the first ram slot, but a smaller ram could fit. right now i'm using G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) CL9-9-9-24) 1.5v. I cannot buy the same version since the ram heatsink is too high, Im looking for 2x4gb ram which will work with my current ram and fits under my Cooler. Brands don't matter as long as it works. Will G.SKILL Ares Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9D-8GAB work with my current ram? or...
