Question For HyperX 3500 Users?

Whats up all..heres the question. What are you guys running your HyperX at? Default voltages and timings...or are you Aggressive...and what have been the results...

I'm tring to figure out what to try and if its worth it or not..

I run my 512mb sticks in dual channel, 400mhz, 200FSB, 2-2-2-5 at 2.6V on my new NF7-S. Thats what I run everyday, but I bump it up to 215 or so for benchmarking keeping the timings the same, and I don't think it's the memory holding back my oc. Yes, I still have to update my sig.
