its not bad, but higher anything leads to more head and more wear on your system. i high fsb is ok if your gettin a high oc out of it, but to have a lower oc and your fsb working more isnt that productive. i would keep the multi at 9x and as far stable as you can get it leave it and you should be fine. 3.4-3.5 range is not common, it does happen but dont let ppl lead you to belive its a common oc for the chip. a 3.2 - 3.3 is more common and more reasonable and a pretty **** good oc at that.
