i know nothing about your board or bios but:
8GB RAM is going to make it a much more difficult to OC.
Im guessing you have 4x2GB sticks of RAM?
Once you start OCing the CPU will take a bit more Vcore, and the NB will def. need some extra juice to hold the load stable,
much sooner than you noramlly would with just 2sticks.
Have you tried upping the NB voltage a bit?
May very well take just a little extra vcore too, but im guessing NB may be an issue
