Yep. Up until the Athlon 1.4, AMD cpu's ran at their stated
speed. With the FPU advantage over Intel P-4's, AMD tried to
capitalize on public perception by rating them compared to P-4's
Now a XP 1800+ definitely has a default speed of 1533 Mhz.
The cpu doesn't tell the motherboard how fast it wants to run, it's
the other way around. You've got a DDR 266 system, the FSB should
be 133 Mhz (Double Data Rate = 266). That means the multiplier the
motherboard sets for the cpu should be 11.5 (11.5 * 133 = 1533).
Yours seems to be runnin at 11.5 * 100. Without lookin at your
board online, there's either a jumper on the board to switch
between 100 and 133 FSB, or a bios setting to do it. Maybe both,
jumper to set 133, then bios tweaks to up or lower that a bit.
You've been seriously UNderclocking that XP John ;) Almost a
heart attack for this ol' overclocker. Don't worry tho, your PCI
bus which the AGP and IDE also uses was right on. At 100FSB, your
motherboard's clock chip used a 1/3 divider (100/3), at 133FSB it
will use 1/4 (133/4) ... both properly equal 33.3Mhz for PCI.
When you get the FSB switched over to 133, these lines will
probly be model name : AMD Athlon(tm) XP 1800+
cpu MHz : 1537.360
Don't be surprised if the Mhz reported is not exactly 1533 or if
it varies a touch from time to time. Actually the FSB is constantly
wavering a little all the time. Tho you're probly set to default
Vcore (cpu voltage, 1.65v) expect the cpu to run just a touch
hotter when you get it up to default speed. BTW, you've also been
runnin your DDR266 ram at DDR200. Expect most everything to jump
up in speed when you get it set properly. I think you're in for a
treat ;)
