THE ATHLON 64 is one mysterious processor. I have been playing with this nice, 64-bit marchitectural delight for last few weeks and am still amazed by it.
What I used to like about Athlon CPUs was that they where almost always unlocked -- at least if you had a decent motherboard -- preferably one from Epox or Abit since they'd fight for your overclocking rights all the time.
Well, the Epox 8HDA+ motherboard based on VIA's K8T800 just got new a bios that even unlocks the multiplier on your CPU, as well as the voltages of your CPU, memory and AGP. The FSB unlocks too, of course. The new bios includes suggested multiplier settings, but if you move these from 10 to 11 on an Athlon 64 chip, nothing happens.
Surprise, surprise: if you set the multiplier to 9, the board actually underclocks your 2000MHz clock CPU to 9 times 215MHz resulting in 1944MHz.
We confirmed this with the Clock Generator application developed by our friend Frank from www.cpuid.com,-the Inquirer

considering most folks here tend to OC by lowering multi. and increasing FSB it shouldn't be too much of a big deal. But it's a bit peculiar why AMD would lock any increase in the multiplier :shrug:
