Athlon and the FSB setting in the bios

[Leempi]

I just upgraded my computer from a P3 500 to an Athlon XP 1700+ with the AASUS A7V266 & 512 megs PC2100 DDR Ram. The whole thing went smoothly (my first time at this too! Miracles do happen), but yesterday i was looking around in the bios and suddenly it struck me that the bios has been set to a 133/33 fsb, with the cpu clock multiplyer at 11. It had done this as i had selected 1467 mhz as the cpu's speed (or something very similar) out of a choice of 3: Manual, 1467, and 2600 something, and it set the fsb automatically (I'm assuming the multiplyer is locked at that 11). I thought i'd see if i could change the fsb to 266 mhz in the bios but it would not go that high, only to 233 or something there abouts (i forget exactly what)

Now i was of the impression that a) the athlons ran at a 266 mhz fsb and b) the ASUS A7V ran at a 200/266 mhz fsb.

Am i missing something? Is my system now running slower than it should be because the fsb is set at 133 MHz rahter than 266? Why didn't the bios when detecting the cpu set the bios at 266 MHz? Should i have that 266 MHz option? (In the bios menu). Have i done something fundamentaly wrong installing this stuff? I'm not exactly sure how it all works (and am looking around on the net for some extra info, but thought i'd post here, mabye someone could explain =).

You're fine.
The 200/266 only comes into the picture when you've got DDR memory. Even if you do have DDR memory, the clock is still only at 100 or 133, but since it's talking on both sides of the clock cycle instead of just the rising side (like plain ole pc100 or pc133 memory), it's effectivly 200 or 266.

Yes, the real FSB is 133 -- though its effectively 266 because of the way the AMD bus transfers data.

You're setup is fine.
