My new build is detecting my Athlon XP 3000 as an XP 2800 (according to POST) - is there a way of rectifying this?

FSB is set to 400mhz and the multiplier is currently set to auto - i'm unsure of the correct clock speed for a 3000 so am a bit hesitant to do it manually!

Setup is as follows:-

MSI KT6V-LSR Mobo
Athlon XP3000
512mb PC 3200 RAM

Thanks in advance,

Kelvin.

xp 3000 is a 333hz cpu so it wont run your memory at 400mhz unless overclocked, if it is registering as an athlon xp2800 i would think you have the fsband the muliplier set up wrong

kelvin

CPU is definitely 400mhz - I have this one here

FSB is set to 200 (my apologies - I was getting in a muddle at first when I said 400 :0) and as stated, multiplier is on auto but i'm happy to adjust it manually if someone can advise me as to what it should be

The multiplier will be locked, so changing it might well mean no POST. Did you buy retail or OEM version? If OEM, did you check the writing on the top of the CPU to check you got what you paid for? To add to the confusion, that CPU comes in two different bus versions: 166 and 200 (forget that clock-doubling nonsense, 200 is the actual speed) - do you know for certain which you got?

I'd also suggest you download a copy of CPU-Z and install it. Use that to check waht the multiplier and bus actually are. The 200 bus version is (IIRC) 200x10.5 .

There are in fact 2 versions of the XP3000+

1. was the 333FSB version running at 2167MHz (13 multiplier)
2. was the 400FSB version running at 2100 (10.5 multiplier)

so for yours you need a 10.5 multiplier.

EDIT: doh meridian beat me to it!

Or your bios might not be up to date - so just goes for the top one at 2800+

I did do a bios update yesterday after doing the build - I have a Windows based utility which lets me do it easily enough so it seemed like the logical thing for me to do. Didn't make any difference...

Windows itself states that the CPU is an Athlon XP 2800"+" - does that mean that it's seeing it differently?

I wouldn't trust Windows to give me the time of day - you need a third-party prog like CPU-Z as I said.

Windows takes all its hardware info and detection straight from the bios.


A good idea mentioned above is to download a CPU ID program to analyse what you actually have.

Thanks again for taking the time to reply

I haven't had a chance to yet, but it's the first thing I intend to do when I get a chance. I'll post back here with the results. My apologies if I sound like a total idiot on this - I just can't get my head around why it's not working the way it should do!

Well,

I downloaded CPU-Z, and it's telling me the following:-

Athlon XP 2800+
Codename Barton
Core Speed: 2109mhz
FSB: 200.9
Multiplier: 10.5
Bus Speed: 401.7mhz

Am I right in thinking therefore, that it is running as an XP 3000 (200 x 10.5) despite only being recognised as a 2800?!

Seems to me like i've wasted everyone's time

If CPU-Z said its a 2800+, I would have the heatsink and fan off, and be reading the processor details underneath.

kelvin

The processor is OEM, and it DEFINITELY states that it's an XP3000 (albeit in miniscule writing ) It was the first thing I checked

The above readouts from CPU-Z would appear to indicate that the clock speed is indicative of an XP 3000 - or have I got that wrong? The 2800 will run with FSB settings of 333 x 12.5 according to a site i've just found (as opposed to the 200 x 10.5 that mine is

I really am sorry if i'm simply being stupid! All I want to know is whether or not my CPU is running at the correct speed!

Kelvin.

Edit - Having just done another reboot to check, I note that the POST screen actually states XP 2800 '+' and not just XP 2800 )

kelvin

Am I also right in saying that if it were an XP 2800, it wouldn't have the "Barton" codename?!

Quick history lesson: originally the 3000+ (the + should always be there) came out in 166 bus only and was 166 x 13.0 = 2166MHz. Once AMD could make a 200MHz bus version, it was felt that the extra bus speed improved performance enough that the new version of the CPU running at 200 x 10.5 = 2100MHz would have the same perfomance, so that was the settings for the new chip.

It looks like you do have a Barton XP3000+ (yes, that core is a Barton) but that your BIOS can't identify it correctly. When did you buy the board? I'd start by updating the BIOS at this point, and if that fails curse MSI for being useless... But yes, your CPU is running at the correct settings.

I have an Athlon XP 3000+. I used the CPU-Z programme and this is what it said

Core: 2162.8mhz
Multiplier: x13
FSB: 166.4mhz
Bus: 332.7mhz

Is this OK?

Its using an nforce2 motherboard chipset

You have the other version of the XP3000+ - read the post above yours.

Thanks for the additional replies, and for the history lesson

I have updated my bios - I have a Windows based utility that came with the mobo that does it for me. I will have a dig around though to try and ensure that I am actually running the latest version It was only purchased last week but I appreciate the fact that that has no bearing on how old it actually is!

I'd also like to take this opportunity to thank everyone who's responded Once again Scoobynet has helped out where other (more specialist!) sites haven't! I appreciate how much of a "newbie" I must sound like in this area and can only imagine how frustrating my replies must have seemed at times!

Thanks for the answers to my questions, and for the advice along the way. I can now relax safe in the knowledge that I have a correctly running XP 3000!

Regards,

Kelvin.

All sorted now

The previous bios update I did upgraded to version 1.9 - evidently XP 3000 support wasn't enabled until version 2.0 which i've just downloaded, and installed from the MSI site

Thanks for all of the help along the way - my apologies that it's proved to be something so trivial!!
