Asus A7N8X-E Deluxe and XP 3000 333FSB problem

[-me-]

I just setup the following:

Asus A7N8X-E Deluxe ; BIOS v. 1008
Athlon XP3000 333FSB
2-512 Kingmax PC2700 DDR RAM
2-WD SATA HHD in RAID 0

PROBLEM:

The MB will only recognize the XP 3000 as XP2800+ when default
settings are used in "Advance Chipset Features"

When I set the multiplier to 14.0X, with the CPU external frequency
remaining at 166; upon bootup the BIOS flashes 1002 MHz (1.2GHz).
This is even lower that the XP2800+ which is 2.08 GHz.

Otherwise, the rig is rock solid. Any help/suggestion will be greatly
appreciated.

Hmmmmm? Sure it's a 3000+ and not a 2800+?
Barton 2800+ - AXDA2800DKV4D - 2083MHz (166 x 12.5)
And there are two different Barton 3000+ chips...
AXDA3000DKV4D - 2167MHz (166 x 13.0)
AXDA3000DKV4E - 2100MHz (200 x 10.5)

btw, The A7N8X can not change the 5th bit of the multiplier, this means
depending on the default multiplier of the processor installed you will
have a choice of multipliers of "up to 12.5x only" OR "13x and greater
only", so if you select 14x with a 10.5 multiplier CPU the mobo will use
a lower bit multiplier.

Thanks Ed! I looked at the chip closer and indeed it was
AXDA2800DKV4D.

So, with the default muliplier of 12.5, does it mean there is no
headroom for me the overclock?

Not at all, you can raise the FSB and lower the multiplier (with an
unlocked CPU - week 38 or early) and some decent ram.

I have a 2800+ Barton AQUCA stepping - 0307(week 7 2003) on a standard
A7N8X v2.00 with Corsair PC3200 and a Vantec AeroFlow HS/fan. Best I can
get out of it is 2378MHz without a prime95 error @ 1.80v Vcore, later
week chips may do better or same with lower vcore.

I've run mine at all sorts of different speeds, 200x11, 200x11.5,
210x11, etc,etc... 210x11 @1.75v with Memory Freq. @ 100% (in sync with
FSB) is rock solid.
