ithink the gold is their top quality stuff. id findout what the cpu's top speed was first at(3/2). then id start out at 200 at 5/4 at 2-2-2-5)with 2.8v and work my way up. when it fails bump up the voltage if u can ( these chips like hi voltage). some of ocz stuff also has voltage regulation built into it so it might not help to raise voltage. anyway i would think u could at least get 220-230 at 2-2-2-5 with their gold cause like i said it supposed to be the good stuff.. hope ive helped good luck flapper
