Ok, last night I tried installing a brand sparkling new Xp 2200+ on my Gigabyte Ga-7zxr rev 3.0 mb. It has a VIA Kt133A chip. Gigabytes website says this board will accept up to a 2200+ so I figured I'd try it out. Well things didnt go so good. I usually just set all my dip switches to 'auto' and hope for the best but this time I think I might have to manually set it, the only thing is I cant read multiplier tables. Could some people help me understand the fantastic world of multiplier tables?!

I have the fsb speed set to 133 via the jumper but the rest is latin to me:


Set System Bus Speed

that long table you have listed above isnt for setting the multiplier... thats for the FSB, you want setting:
133.33 33.33 O X 0 O O (fsb at 133.33 and pci at 33.33)

on page 9 of the manual it has the multipliers

xp2200+ is 1.8ghz
with a 133mhz fsb you get 133x13.5=1.8ghz
so you need a 13.5 multiplier (which im not sure if that board supports)

With the latest BIOS, PCBs 3.x can support 200/266MHz FSB, Palamino(0.18u)/ Morgan (0.18u) Athlon XP/Duron CPUs and PCBs 2.x or below can support 200MHz FSB, Thunderbird (0.18u)/Morgan (0.18u) Athlon /Duron CPUs.

its kinda hard to find palomino athlonxp cpu's any more also (they were the original athlonXP, but havent been made for well over a year)
