I've been running my XP2500 at 2.2GHz on an Asus A7N8X Standard (rev 1.6)
mobo for almost a year now. I recently bought an Asus A7N8X-E Deluxe mobo,
and installed everything, and continued to overclock successfully. It was
running BIOS 1.007 when I got it, so I decided to try out some new ones.

First of all I tried the official 1.008 BIOS from Asus. Then I decided to
try the 1.008 Uber BIOS. All was OK, apart from one or two boots where the
machine wouldn't post. There was just a blank screen. On those two
occasions, a quick RESET sorted it out. Suddenly, though, it didn't want to
boot up at all, and I ended up disconnecting just about everything from the
machine, clearing the CMOS etc. Only once I had [reluctantly] disturbed the
CPU, and then reseated it, did the machine decide to boot.

After this, though, when I boot up, on the very first screen, instead of
telling me I have an Athlon XP3200+, I now get told I have an "Unknown CPU
Type @2200MHz". I have tried reflashing back to the official 1.008 and the
original 1.007, to no avail. SiSoft Sandra indicates that performance is as
expected with my overclock, but I can't help thinking that something else
must be wrong for this to be happening!

Any ideas?

Can't you just go into the BIOS and select XP3200+ ??

No. The processor 'label' is determined by a combination of the FSB and the
multiplier. My processor, being a Barton, is currently running on 200MHz FSB
with a x11 multiplier.

If i set my Mobile barton 2500+ to 11x166 it reads Athlon 2500+ Mobile.
When set to 11x200 I get same as you or message...unknown cpu @ 2200Mhz
Asus A7N8X with 1007 Uber Bios.

200MHz System Clock x 11Multiplier
= 2200 MHz FSB
= 400 MHz DDR System Bus
= Equivalent to an AMDXP3200

Happens on some nForce MOBO / memory combination You have arrived
at the right destination via a different route - it's stable is it ?,
if so don't worry it's giving you the right everything - just no POST
description.

It was definitely labelled as being for my board. And the file naming
convention followed suit too.

I think I've sussed what is wrong. I must have damaged the chip when
refitting it, as I now notice that my L2 cache is only 64K. I will
investigate further later on this evening.

I guess that is why my mobo cannot recognise it to be a Barton now? Methinks
a mobile XP2500+ will be the next choice. Though does anyone have any
experience with the XP2600-M yet?

Use CPU-Z...I ferget web addy...H-Oda.org i think.
Anyways Are you sure your nnot looking at the L1 Cache?
Also A 2400+ Barton Mobile might have a little more headroom to O/C over the
2600-M
They can all be found at www.newegg.com
I doubt your cous is hosed...My board never saw a 3200+ when I set 11x200...
It could be that even though you flashed backwards the part of the Bios that
ID's the cpu doesnt get over written.

Got one on a Shuttle AN35N and I love it! I am running it
at 11x200 @ 1.5 volts because of temp problems when I go
higher, but I know it will do 2500Mhz stable. I need fix an
airflow problem through my case, then I'll make her fly.

I'll try what you said, but I'm off out at the moment. Thing is though, on
SiSoft Sandra's cache memory test, my performance has really dropped off. It
used to be up there with the XP3200+, but now is petering out near the 128K
mark. 😱( It was definitely the L2 cache I was looking at.

Maybe a crack i the core where the cache is...🙁
Bummer if its broken.
Just keep in mind you will probably see UNKNOWN cpu again with the
mobile...I will look for Bios 1008and see if it reads mine as a 3200+
(11x200) and post back.
Again Bummer on the cpu bein hosed but had to make sure....
The 2500+ I think is a good deal for about $90 US at newegg.com

A closer look at the CPU has revealed that I have broken one of the resistor
groups. One of them is split in half, and although this is probably the only
fault, I am not confident enough with a soldering iron to do this sort of
soldering to replace it.
