Hey, anyone out there know about how high I can push the FSB of my Barton without increasing the vcore? The memory should be able to handle 400 even at low latency, but I don't want to push the CPU that far too fast. Right now I've got the FSB set for 174 and the temps are about 42°C idle. I'm basically just looking at a ballpark figure that some people have done successfully. Another question: I've read some places that the 2800 is factory unlocked and some say it isn't. Is there a way to tell by a set of the bridges? I really think it's locked, because I don't have the mobo setting any particular multiplier (on auto) and it reads as 12.5. So, I figure something has to tell the mobo what multipier to use, or how would it know? Is the auto-unlock (if any) a feature of the nForce2 boards?
