disable boost and set performance enhance to standard.tell us what happens after that.ando try to set your RAM voltage to its rated voltage or lower.Never leave any voltage in auto when oc'ing.

I tried with dram voltage at 1.64 (recommended is 1.65 but I do not have a 165 setting) and cmd rate of 2. I am till having the same issue. Is a memory oc issue or cpu?

Your Memory OC is the issue

Do you Have a d0 Stepping Model? Those OC beautifully
Just read through this as well

http://www.overclock.net/intel-cpus/538439-guide-overcl...

Cooling is also vital So Read through this (Intel Temperature) and pick 1 (They are basically identical performance wise)

Good Luck:D 

Just another Quick thought is that Maybe you Are overheating? Any temp readings? please tell me that you are monitoring them
