Need Help, Bogus CPU?

[ccwwnn]

Hey all,

First, I know my rig ain't top of the line and a little outdated but it works for me.

I just got a new(?) CPU and am seeing some discrepancies.

Supposedly I bought an Athlon XP 3200+ part number AXDA3200DKV4E

The CPU appeared genuine and was marked with the correct part number. (I can take pics but it's running right now).

Not having much success achieving the speeds I thought the CPU could handle (400 Mhz FSB, something higher than 2.2 Ghz etc.) I checked using a few programs and found that it seems to be only a 3000+. (screenshot below)



A couple of other programs have identified it as a 3000+ as well.

Is there a chance the programs are not correctly identifying the CPU or is it a 3000+ altered on the exterior to appear to be a 3200+?

Any info you can provide would be appreciated.....I bought this from a supposedly reputable dealer.

have a look at this pic and see if the same bridges are cut (you can the dark stop where each is cut with a laser)

L3 is the main one to check first... none should be cut.

if you are not overclocking 13 x 333FSB.. that would make it a AXDA3000DKV4D

if you want to look at the bridges for XPs.. this site will help

thanks for the reply, I will check out those bridges tomorrow and see what I find.

right now yeah, it's at 13 x 166 (DDR=333)...but I was under the impression the chip would return it's correct CPUID info regardless of how you had your BIOS settings configured...am I mistaken? I guess that program might be pulling the id from a database rather then the chip itself?


What surprised me me was the actual referencing of the AXDA3000DKV4D number in the extended info section when it specifically states AXDA3200DKV4D on the chip exterior.

hmmm, now I am confused....it turns out the OPN and CPU String being generated by various CPU ID programs are dependant on how my systems BIOS is configured.

I can get just about any Athlon XP OPN to show up if I set my BIOS for that particular model. (2500+, 2600+ etc.)

I still cannot get the correct OPN to show up but I believe that to be because of technical limitations imposed by the mobo chipset. (Abit KD-7 w/KT400). Unless I can get the CPU to boot at 400Mhz FSB @ 2.2 Ghz, it will not show up as the Athlon XP 3200+ (AXDA3200DKV4E). And I cannot boot at those speeds from what I have determined. (overclocking is not my forte but I believe the absence of 6 way divider is my major problem, the KD-7 only has a 5 way so anything above 170-175 FSB starts becoming unstable.)

I guess I have two questions if anyone can help....

1. Is a 200Mhz FSB possible in any way on the Via KT400 chipset (Abit KD-7 mobo)?

2. Shouldn't there be some way to determine the model CPU you have regardless of how your system has it configured? The CPU visually appears genuine and it runs at 2.2 Ghz with no issues, temperatures are quite low with just stock cooling so I am not stressing it, benchmarks are as I would expect, although it's currently only running at 170 FSB as opposed to 200 or possibly higher. Which is why I believe I cannot get a program to dispaly the correct OPN......but once again, shouldn't that info be inherent in the chip istelf, I mean, one would expect that AMD would be able to verify each and every single CPU, when it was made, where it was made, what model it is, etc....is this not the case?


oh yeah, Merry Christmas! (and if that offends you, Happy Holidays!)

The board has some fairly extensive options as far as OC'ing but like I said above, the one major factor it lacks is the 6 way divider....no matter what I do, I can only divide the PCI bus by five so once I go above 166 FSB, there is no way to stop increases in the FSB from being transfered to the PCI and AGP Bus(s)

So really my limitations are how high can my PCI and AGP bus go before becoming unstable.....my experience leads me to believe the AGP can run at 75Mhz stable which, divided in half for the PCI is around 37 or so.

and that puts my FSB at 185.....trying to get to 200 would be tough, that would put my PCI bus at 40 and my AGP at 80

My memory timings can be set independant of the CPU so thats not an issue, just the PCI and AGP bus are a problem.

It's the stupid chipset on the board, I mean, I can't even run DDR400 with a 333Mhz CPU, it just won't do it, it rolls it back to 333.

hmmm, might be time for a newer chipset.....I just wish I could be sure just what exact processor I have....I am pretty sure ta this point it is legit but I don't know that for a fact.
