New RAM gone wrong?

[nkim2069]

M. board : MSI FM2-A75MA-E35
CPU : AMD Athlon(tm) x4 760k Quad Core 3.80 GHz
GPU : AMD Radeon HD 5770 series
(OLD) Ram : G.SKILL DDR3-1333 PC3-10666 2048MBx2 CL 8-8-8-21 (2x2gb) 1.5V
(NEW)Ram : G.SKILL DDR3-1333 PC3-10666 CL 9-9-9-24 (1x4GB) 1.5V

Hey everyone, I got my new ram recently and installed it of course. What I did in the beginning was, I took one old ram stick out and just put the new ram into the old slot. I tried to play battlefield 4 but the FPS was horrendous so I switched the ram positions and it worked but I would crash every so often. I ended up taking the old ram sticks out and just leaving the new ram in but it would keep BSOD and crashing or no BSOD and just crashing. If I just browse on the internet or talk to my girlfriend over skype it would be fine but the minute I join a game my computer craps itself. Any help would be appreciated. Thanks!

1333 isn't really a good choice for your combo, I'd look for 1600 or even better, 4GB isn't really ideal for games, and mixing DRAM can be problematic so even wih 8 GB in a 4GB and a pair of 2x2GB problems can still happen, would try with all sticks and raise DRAM voltage to 1.575 and the CPU/NB voltage up to about 1.2

Which slot do you have the memory installed in? Use a memory test like memtest86+ to see if it detects any errors. If so, send it in for RMA exchange and get a dual channel memory kit like F3-10666CL9D-8GBXL
