ok u got a low vid thats good....set ur multi to 8 and FSB to 400 that way your reaching 3.2 gig and you can leave your ram frequency to 400 (800mhz speed) (default)..as for voltage what memory is it? look at the memory manufacturers website for volt specific... you leave it at default speed as your fsb will be 400 and ur multi will be 8 you wont need to up the votlage for mem your v core for 3.2 ghz should run at 1.3 with that vid of yours.......
really take a look at the oc stickies...hell i joined only a month ago and i was noob...i pretty much learned everything since then and my system is oc to the max with room for more...just read some guides!
