Need help with blue screen of death

[WhoAteMySoup]

Mods, please feel free to move this thread to an appropriate place (I am new to this forum). Also if this has been answered before, as I am sure it has, please point me to the right location.

I have been experiencing occasional blue screens due to Memory Management errors during gaming or just random internet browsing with several youtube pages open. This has been pretty infrequent so I have never bothered to really troubleshoot. As of late I am running into this a lot more often, as in 3-4 times a week, so I decided to try to isolate the issue. I ran Prime 95 blend test and got two errors after 7.5 hours... not having experience with this test I am not sure what to make of it. I also ran the built in Windows RAM test, all of which have passed with no issues. Any suggestions?

My rig: AsRock Fatal1ty Z68 motherboard
Intel i7 2600K @3.4Ghz (no overclocking as of yet)
16gb of Ripjaws RAM
GeForce NVIDIA GTX780 graphic card
1000W Cooler Master Silent Pro power supply

I assume the OS is Win7 and the error code is 0x1a? What are the current effective DRAM frequency and timings per the Memory tab in CPU-Z, and what's the current DRAM voltage setting in the BIOS? What are the rated frequency, timings, and voltage per the SPD tab in CPU-Z? With 16GB of RAM installed, and depending on the current DRAM frequency, you may need to bump VTT voltage from the default of 1.05V to ~1.1V. What does CPU-Z show as the no-load Vcore, and while at 100% load running Prime?
