RAM and overclocking:
Most instabilities in overclocking are actually due to the RAM.
If you overclock the CPU, make sure you aren't overclocking the RAM too. You need to play around with the multipliers so that your RAM ends up the same frequency (i.e. 1600MHz).
Simply increasing the BCLOCK overclocks the CPU and RAM equally. You don't want that.
Once done, run Memtest (memtest.org). I recommend the USB or CD. You must have whatever you use PRIOR to the hard drive in the boot order (BIOS).
As far as the memory goes...I have the multiplier on my memory turned way down as well as to keep it safe from my experimental bclk boosting. Its running at a much lower frequency than intended so I should be good right?
