High FSB/Low Multi or Avg multi & FSB?

[DangerIsGo]

So I have the Expert board and was OCing my Opty and had a few questions. Should I have a high FSB and a low multi with a divider to keep RAM around 280MHz (ballistix...where speed would cap off), run a 1:1 (280), or pick a nice round number between 280 and (insert number here) and try with that (obviously w/ a divider)? Or should I just lower the multi as low as it can go and see how high i can crank my FSB? what do you suggest? Odd thing is that on my A8n-sli deluxe board i reached a max OC of 280x10, but this one I cant break 2.7GHz

I would keep the 10x multi since it puts less stress on your mobo and could require less voltage. Plus, you're probably more likely to break 2.8 with 280 then 300+
