I've got an i7 4820 and a sabertooth x79, its been running fine with overclocks of around x48 and able to handle pretty much anything.

lately i discovered a particular combination of programs (essentially windows media player, imacros on firefox and photoshop) is giving me a bsod "critical process died" which makes me think the overclock is not so stable.
so I moved back to x37 but i'm still able to reproduce the crash.
im not sure what to do to stabilize this as it should have plenty of power?

also something else I'm not sure is: recently i upgraded my ram to HyperX Savage Red 16GB (2x8GB) DDR3. (didnt help with the problem). the xmp profile sets the vccsa to 1.3v or 1.35v which seems a little high to me? particularly since the vtt cpu should be set to about the same but i see its not recommended to go over 1.2v?

my settings are:

bclk 100
multiplier is x45 or less
dram 2133 11-13-13-30-2t
vcore is set to offset + 0.240v
cpu vccsa manual 1.3v
dram 1.65v
cpupLL 1.9v (tried increasing from the default 1.8 not sure what's the correct value here?
vttcpu 1.25v
cpu LLC ultra high - 120%
vccsa LLC high 120%

thanks a lot in advance!
