But I haven't seen it possible to overclock yet because nobody has the proper data to upclock the chip. Don't even know if you need a hard mod or if it will work with a bump in FSB.
Running Prime95 for 20 minutes my temps max out at 65C, plenty of room for temperature increase, even 20C. With ThrottleStop I can drop my temps a good 4-5C by reducing the voltage.
Granted, not sure how tolerant the rest of the components are to a faster FSB, but it couldn't hurt to find out. I wouldn't doubt if you can reach 2GHz with this chip no issue.
