I did some research on overclocking Athlon XP and found out, that AMD started locking the multiplier at some point. Multiple sources stated that AMD started locking the multi in week 35 of 2003, but still sold CPUs with an open multi at this point. Starting with week 43, all CPUs had their multi locked.
So I got myself a sample from week 30, to be sure it has an open multi:
To my surprise I can't change the multi. I did lower the multi to 12 and it doesn't post.
Anyone got an explanation for that?
Might my CPU be a fake?
