Hi all,

Does anyone out there have an A7N8X-Deluxe Rev 2.0 running an AMD XP3200
(Barton core) on it? I have, and I've been having heat problems which I
think I finally narrowed down to the Vcore running at 1.85v instead of the
1.65v recommended by AMD.
I was running BIOS 1005 in which the lowest Vcore setting was 1.8v, so I
have just flashed to the latest (version 1008) and guess what? The lowest
Vcore is *still* 1.8v!
This board is meant to the be able to handle this chip isn't it??
 
The latest BIOS for the A7N8X-E Deluxe rev 2 I have is "ASUS A7N8X-E Deluxe
ACPI BIOS Rev 1011", date 05/20/2004 (updated with ASUS Update)
 
I have the A7N8X-Deluxe 2.0 running an AMD XP3200 (Barton) with BIOS 1008.
Vcore is at 1.65 volts. Perhaps you have another problem?

Have you read the thread "How to identify an Athlon CPU" by Erik Harris
(message id (e-mail address removed)) ? He bought
a XP3200 from Mwave, and it appears the product is an XP2500 that has
been remarked with a new label, and perhaps one bridge was modded.

Did you buy your processor from Mwave ?

Maybe some bright remarking specialist decided, that to guarantee
the XP2500 he was using would run as an XP3200, he changed the VID
bridge to give it extra voltage. It occurs to me that AMD allows
adjustment of the voltage by +/-50mV from the specified value, and
since the BIOS offers 1.800, 1.825, 1.850, that means the processor
is set to 1.85 volts (00000 VID code) and the BIOS is allowing you
to undervolt by the legal 50mV amount.

Have another look at those bridges...

HTH,

This is very worrying, I shall have the HS off later and check none of the
L12 bridges have been burned open. As it happens the chip came from ebay -
supposedly a reputable dealer. We shall see.

Thanks for your help!
