Yeah, you can't assume that you would be able to OC to 2.2ghz, thats just what some people got with certain steppings

You will need some serious cooling for 1.85v, I wouldn't reccommend it as it will shorten the life of the chip.
60c is a bit hot, and you should always add a few degrees onto that unless you put the sensor in between the CPU and heatsink.
2000mhz is a good overclock for that chip anyway. Quit moaning, you've got it up to like 2600+/2700+ or something like that anyway.
