AMD Athlon XP1800+

I have the above CPU in my PC. How do I tell if its a Palomino or T-Bird chip?

They do not make T-Bird that size, yours is a XP1800+ I have a XP1600+ running at 1700 but had it running at 1900 for two weeks without extra fans no Probs at all

you are correct, but AMD do make two versions of the 1800XP, and other speeds as well. the two versions are in the model number which will be model 6 or model 8.

This number is on the chip itself, not sure how to tell the difference without actually looking on the top of CPU. but it refers to the thickness of the wafer. Regards. J.

If I check system information I get-

Processor x86 Family 6 Model 6 Stepping 2 Authentic AMD 1539 MHz

Does this mean anything?

thunderbird core was only used till 1400, unless you are confused and mean throughbreed, which replaced the palomine core, this would show up as family 6 model 8. I don't think there was much performance difference, other that the fact that the throughbreeds were easier to cool. Being 0.13 microns as opposed to the 0.18 microns of the palomine.

Yep! that's the same model number as my 1800XP, it means the thicker wafer of the earlier models and runs at a slightly higher temp. than the model 8.

If it is of any help my CPU runs at 52c all the time with no problems at all.

When I spoke to the AMD technician over the phone he said they, (AMD) didn't quote a normal/recommended running temp. because of all the variations in system setup's, only a Max. temperature for each range of CPU's, these vary from 85 to 100c. J.

i have a 1800+ it runs at about 59c the max stated is 92c(on the site i looked on anyway)so mine is well within its range, if you are getting anywhere near the 70-80 mark it may be worth checking your fan.

Thanks for the info although its not a temp. issue (BTW mine runs at similat temps under 100% load).

Reason for asking was I would like to know the fastest CPU I could use with my mobo (Jetway 266B).

Website quotes different speeds depending on CPU.

Thanks again

All the replies above are correct, and I'm sure someone will advise you on the fastest CPU for your board.

The AMD site is excellent, but a little difficult to find your way round. If there is any info. you need and can't find, just drop an e-mail to, [email protected]

They will normally reply within 48 hours with a personal answer to your question. Being a bank holiday this weekend, it may take a little longer. J

Found this page at their website not sure what the BOM version refers to perhaps you do.Looks like your lucky with version 2 right up to 2600+
