Who to believe...WCPUID & AMDCPUID or my bios

[RU482]

I unlocked my XP1600 a while back and have been playing around with it on my ASUS A7N266-e, trying different speeds. I just noticed something whacky. I downloaded AMDCPUID off of AMD's website.

My bios is set up for 150FSB x 12.5 multiplier = bios says 1879Mhz, as does ASUS probe
AMDCPUID says 1662 Mhz whether, at an FSB I try. Could it be that this utility is basing it's results on the multiplier and the assumption of a 133Mhz FSB? Or is my Bios and ASUS probe utility lying to me?

If so, are any of the OC number people are getting "real", or just lying bios'?

Interesting, I downgraded from v1004 bios to v1003 bios...not only can I NOT boot at 150FSB, but AMDCPUID is reading the correct speed. (when I bump it down to 140Mhz FSB, AMPCPUID reads 1744Mhz)

Would ASUS put some type of protection (or a cap :Q) from overclocking in the bios? Also, I noticed when I did have v1004 loaded and the bios was telling me I was running at 1879Mhz, my distributed folding numbers were't much higher than my NV7M machine with a stock XP1800.

So WTF, is ASUS trying to pull one over on us to become the overclocking champs?

HUH, another funny thing. w/ version 1003 bios, if I have the multiplier set to 12.5, AMPCPUID identifies the CPU as an Athlon XP2100+
w/ version 1004, it only id's the CPU as Athlon XP\

weird

Never heard of AMDCPUID, but get WCPUID.

Do a search for it on google, I find it to be the most accurate out of all these programs.

OK reloaded v1004 bios and set it to 150fsb x 12.5multiplier = 1875, as confirmed by my bios, ASUS probe, and the boot screen.

When I run wcpuid or amdcpuid, they tell me 1662Mhz

WTF :|
