One of the last(?) brown Palomino AthlonXP with AGKGA stepping. It is from week 48 2001.

It has a chipped upper right corner, but it still works perfectly, yet hot :)

This could actually be the latest Palomino on brown suit. It is marked 12th week of 2002. Even with a hole in the upper left corner it still works at 1,150 GHz.

Hi it's me again. That mobo wasn't set up right. I just found the right settings and, despite of his hole on the upper left corner, now is working at his speed 1.533 MHz. Very sturdy CPU...

I don't know if my CPU or my mobo is busted.
But I tried to increase the FSB to 133 from 100, it is supposed to run at 1.5ghz not 1.15ghz right?

Brown Palomino

Response: Yes, it should run at 133 MHz FSB

when clock is 100 it works on 1450, and on 133 is 1.93=2.0

Overclocked and stable

I've had the Athlon 1800 cpu in my computer for about 4 years now, and not having the funds to upgrade my entire system, I FINALLY decided to try out the overclock features on my Gigabyte GA-7VAX (KT400 series) motherboard.

I went from the original 1.53ghz to, with 100mhz x 18 (clocking at 1.84ghz) it is now registering as an Athlon XP 2200+
and stable for 1 week straight now

I would LOVE to see how far this cpu could be pushed, however, the multiplier does not go past 18x on this motherboard :/

Oh well, coupled with 2gb of DDR 400mhz ram and an ATI Sapphire 3850 HD 512mb AGP graphics card, I am able to play EVE online at medium graphics levels with 0 crashes and a smoooth framerate.

(the same as my buddies brand new $1500 setup with a duel core Intel 2.4ghz cpu)

Altogether, very impressed with this old cpu. Even with the overclock, and original cpu cooler, its only reading 8 degrees Celsius warmer than stock settings at max load.

I would recommend anyone still rocking the Athlon 1800 to try overclocking before dropping big money on a new system. Total system upgrades for me from memory express:

1gb Kingston DDR 400mhz ram = $35
Sapphire 3850 HD 512mb AGP vid card = $120
(AGP is a 'dead' technology now, you may need PCI, or PCI express card depending on your motherboard)
450w Corsair powersupply = $80
(450w minimum required to run new graphics card, I previously had 360w Thermaltake PS)

Total = $235
Comparable system now days, new, $600-800

I use this processor for nearly 5 years, it run perfect. The only problem is regarding with heat, but never mind I upgrade original heat sink with powerful fan and it run cool- about 50 degree c.
