Why do I have to downclock my Athlon XP

Hi everyone

I bought an XP 3000+ Barton CPU on eBay about 6 months ago and since I have it, I need to downclock it to 158 Mhz or my computer has random crashes. I changed the RAM, motherboard, graphic card and PSU since that time and, no changes. I still have the sameproblem. The temperature on idle at 50C and peak at about 56C so I don't think that's the problem

Here's my system:

Athlon XP 3000+ Barton (166mhz)
ASUS A7N8X-E Deluxe
Enermax Noisetaker 2.0 EG495P-VE SFMA 2.0 485 watts
Zalman CNPS7000B AlCu
ATI AIW Radeon 7500

There are no visible defects on the core and I always use a CPU shim.

Did any one ever had that problem ? or have a solution ?

I have an old 733mhz Celeron next to me on the floor that is slightly overclocked from 633mhz. It also crashes randomly, but luckily I've gotten two other computers after it that were stable.

One thing we both have in common, we have processors that were previously owned by other people. =\

This may be the problem with some tinkering on their part that made the products permanently damaged at a certain point.

I'd just go at the reduced speed, and stick to buying OEM and Retail from reseller sites and not ebay.

Great advice ! I'll never buy a CPU on eBay again but do you think AMD will RMA it ? I don't see any tempering on the CPU.

I think you already figured out the problem

I believe people are selling fake athlon xps on ebay too.

Check the model number (it's usually on the CPU core, so you might have to clean off your thermal paste) and compare it with this list

There's nothing written on the core directly, maybe I wiped it while cleaning Arctic silver. Could this information be found elsewhere ?

is it green?

It might be on a sticker on the top part of the processor. Your looking for something like: AXDA2000DUT3C

EDIT: I've never wiped off the model number before, and I use AS5.

my Athlon is brown, I'll check the sticker tonight. It's a shame I have to remove the HS, I just installed it last week (CNPS 7000AlCu)

might be a long shot, but you can try using a line conditioner or a ups.

My CPU is an AXDA3000DKV4D so it doesn't seem to be a fake

previous owner probably just overclocked the heck out of it.

What kind of memory are you using?

I have 2*512 Mo of Corsair Value Select.

By fake, do you mean where the dudes are selling remarked mobile cpu's as desktop CPU's?

Personally I'd be delighted if I got an Althon XP-M instead of an XP or a Turion64 instead of an Athlon64. Unless you meant the other way...

I was curious about the topic, so I did some searching.

Apparently, one of the modes of fakery is to take a lower cost mobile CPU and cut/bridge links to make it appear to be other than what it is. While WE might like it for power dissipation/silencing reasons....
