BSOD when playing games. BlueScreenView says ntoskrnl.exe caused BSOD

I keep getting BSODs when I play games for a short while. At first I thought it was a bad installation of Windows, so I did a clean format (full) of my SSD and a clean install of Windows 7 Ultimate x64. Installation failed quite a few times before finally succeeding. Tried another copy of Windows 7, same install failures. I finally finished reinstalling Windows 7 on my PC. I suspected the RAM to be at fault so I ran MemTest86+ and found a ton of errors. Upon closer inspection of the BIOS settings, I found that my board was clocking my ram in [Auto] mode at 1333mhz instead of the factory 1600mhz (Corsair Vengeance LP DDR3 @1600 CAS9 on Asus Sabertooth Z77). I updated my BIOS to the latest as of this posting and I still have to manually set the memory frequencies for it to run at 1600mhz.

Everything seemed fine for a few hours running prime95. I supposed my PC was fine now after that clean install of Windows 7, but a few minutes into playing Battlefield 3, I BSOD. I am no pro at reading dump files and I was hoping someone could help me isolate the sources of my BSODs. I've attached the minidump files for each BSOD below. Thanks!

My system specs are:

Intel Core i7-3770
Asus Sabertooth Z77
Corsair Vengeance Low Profile DDR3 @1600mhz CAS9
Kingston HyperX 3k 120GB SSD (boot, Battlefield 3, Microsoft Office)
Asus DirectCUII GTX 670
Thermaltake Toughpower 1200 watt
Razer Blackwidow Ultimate
Cyborg RAT7 Mouse
