Why don't u try finding out your CPU and RAM's OC limit separately?
For CPU, set ur FSB at 200 (or any number u're sure it's stable), and increase the multi. Increase vcore as and when needed. Stop when you reach the max vcore and get a CPU temp ur not comfortable with (eg. Ard 1.9v and >52C). This would give u ur max clockspeed.
For RAMs, set multi to something low, eg. 9, and vcore to something decent. (Can be set abit high, so that u're sure it'd be stable and u'd also kinda be burnin in ur CPU) Increase FSB from 200 in increments of 5, with very relaxed timings, eg. 3-4-4-11. After u find ur max FSB, u may want to tighten up the timings.
Note: You can try a modded bios before tryin for the highest FSB.
