how could i test my on die memory controller? What tests to run, Could I do say test till i get 1 or 2 errors in memtest86 then bump up vcore and see if they go away?

I've tried 1 stick and been in bios memtest at 315mhz. errors like crazy tho. My chip seems to be a masterpeice work of silicone.... so I dont understand how my chip is good but my memory controller is bad, I just ran superpi 1 mil at 3ghz on air with 1.6vcore, when I have a day off work I'll test the winny i have and see what these sticks do.
