Asus A7N8X Deluxe

[davemar14]

Hi,
I currnetly have an Asus A7N8X Deluxe motherboard. I am running an old AMD Duron 900 MHz on it. I want to put a new AMD Athlon XP 2500+ Barton CPU on it. Is there any problems with upgrading it? I heard the N-Force 2 will support the new CPU's, but will I need a BIOS flash. I had some problems with the BIOS when I first built the computer. So I am a little hesistant to flash the BIOS. Thanks!

My system is as follows:
AMD Duron 900 MHz
Asus A7N8X Deluxe
Corsair 512 DDR 400 (2 X 256)
GeForce 4 Ti 4200
SoundBlaster Live 5.1
Western Digital 80 GB w/ 8 MB cache
Seagate 20 GB
DVD and CD-RW drives

Bartons work, but the motherboard won't know what to call it. Instead of seeing "XP 2500+" you'll see something like "AMD processor at 1800MHz". BIOS will fix that message, but I believe the message is the only thing wrong (actually, maybe it's the only thing right?).

Mine is shown as "AMD Athlon XP 1100MHz", which is a little concerning

My board is rev 1.04, and it already had BIOS 1002 on it. Any suggestions for getting my processor to work at (or at least be shown at) the correct speed?

the bartons run on a 166fsb i suspect you have your bios set at 100MHz. 100MHz * 11 multiplier = 1100MHz. 166MHz *11 =1833MHz.

I'm out of my mind, but feel free to leave a message.

Well, it *claims* to be running at 166FSB. The CPU_FSB jumper is set in the 266/333 setting on the motherboard, and 166FSB is set in the BIOS. Seems a little odd to me. I noticed the Vcore is being read as 1.25V - this seemed a little low to me?

Are you certain that's what BIOS says your CPU BUS speed is running at? Your board is capable of running the MEMORY bus at 166MHz and the CPU bus at a slower speed, it sounds like you're running a 100/166 CPU/RAM ratio.

It's described as "CPU External Frequency" in the BIOS, but yes. I've tried clearing the CMOS, but this had no effect either.

Bit baffled tbh

Check your clock frequency. If it's set higher than 12.5 it will also say 1100Mhz (you have to cut last L5 bridge to unlock higher multipliers).

XP 2500+ Barton @ 2235Mhz
A7N8X Dlx
2x512MB Corsair PC3200
MSI GF3Ti 500
16x DVD-ROM
2x80GB 7200RPM Maxtor

The multiplier is meant to be 11.0 by default - which still results in a 1.1GHz clock frequency. Only the 9.5x multiplier is nearly satisfactory, running at 1583MHz. This seems to be a memory problem, anyway. This has been explained further at http://www.amdforums.com/showthread.php?s=&threadid=211140
