Are you using a sandy/ivy bridge cpu? also is this your ram? http://www.newegg.com/Product/Product.aspx?Item=N82E16820145313
There are problems using 1.65v ram on sandy/ivy (I can't recall the exact reasoning but I "think" its that it uses the same voltage as the cpu) (also I heard its not particularily good for the cpu to do so, not sure if this is true)
And since your bsods look to be memory based I would just rma the ram and get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233202
1.5v and they fit under bigger heatsinks no problem.
Obviously more trouble shooting would help but if you can't get into memtest because of blue screens, not much we can do sadly.
