Have you googled your motherboard to find other people with E5200's? I'm wondering if your MoBo is holding you back. Do you have the most up to date BIOS for the MoBo?
Good luck. 3.3-3.5GHz should be a realistic goal.
There is no dram to cpu ratio on my mobo, just uses the mch strap function. I'm positive I can get it higher since I'm not even at 1.3625 Vcore yet, just need to get the heat down first, hence cooler.
