OCZ pc3500eb or Adata PC4200

As the name states, I have a p4p800 deluxe mobo and a 3.2e.


I was wondering what is going to be BETTER ram for overclocking this badboy, 2x256 of the pc3500, or 2x256 of the pc4200?

u want the best timings between 230/250. pc4200 would be a waste. i would either buy some used bh5/6 that will run that fast or some used ocz eb pc3700 or lastly the crucial ballistix it runs great timings at those speeds .
