Lower your multipier and up FSB, I tinks no your ram problem, your board give up before your ram hit its own speed. I think the best way it's ower multipier to 6 and test your board for highest FSB.
no way you should put 1.6v through a wolfie, u will kill it . Also why are you trying such a fsb with low multi. Most boards now and since 680i have done 450fsb + easy and with a high multi ure laughing.
Lower the fsb like sugested and higher the multi dude
