I got the 6400+, don't know if I'd go that direction again. It's the hottest chip I've ever run, even under water, Swiftech MCP350 pump, Dell XPS 710 Rad, Swiftech Water Block, runs 30C idle, 40-42C load. Under a ThermalRight 120 Ultra, load ran 46C with upward creep, nMedia PC IceTank ran 55C load with a lot of creep. Runs like a dream though if you don't mind lack of OC overhead (probably not going there at work ) Normal non-100% working load it runs pretty good.

About vcore modding. According to this article, the next step is to identify the resistances connected to pin #4 (FB) and pin #33 (NB_FB) and shade those.
The chip is located next to the mobo's power plug, close to the cpu. Guess I must remove the heat spread connector to inspect this pins.
