Need new ram to get higher OC?

I currently have an 8RDA and 2 512mb sticks of HyperX PC3500. Should be really nice ram, right? Well, I can't get either stick to go one mhz over its 216mhz rating. I'm wondering if this could be a function of the motherboard. I just ordered an NF7-S that should be here Wed. Am I going to need new memory to see that sweet FSB I'm after, or might the HyperX run faster on a different board? If memory wasn't so pricey these days I'd pick up some new stuff, but better stuff than I have now is really expensive.

that sounds really weird. what power supply do you use?

I have a 300W ExoticPC Silenex. The 12 and 5v rails are a little off, but my Vdimm is rock solid,

I'm a little stumped to be honest. You are sure that it's not the CPU holding you back? if you're not then lower your mulitplier.
