As subject says, i just upgraded to 12gb of triple channel Corsair Vengeance from the stock 6gb that came with the aurora r1 back in the day. Following the recommendations linked here by Chris :

I raised the voltage up 200mv and it all booted up nicely.
Now im probably just a worry wort, but ive just read lots of horror stories and what not about having to high of voltage. Also it does seem that my case fans are more active now.. but it could just be me being paranoid haha... Either way in general should i have any worries at all or am i good? Not trying to fry anything by OC'ing to much
