Dumb question about KT133A

[BlackDragon8303]

Alrighty guys I got a T-Bird 900mhz @ 200mhz fsb but is it possible for me up my FSB to 133 and slap it in an asus a7v kt133A since it needs a 133mhz fsb. I mean arent the 133fsb T-Birds the SAME as the 100fsb T-birds? Also All KT133A boards are capable of DDR ram correct?

The KT133A chipset does not need a 133 MHz FSB. It could run your current chip at 100 like it is now, or you could increase the FSB to 133.

I believe that the chips are "the SAME" but that they're at differently rated speeds.

KT133A boards are not able to run DDR ram. That requires a different chipset (the 760, IIRC).

For the 133MHz FSB Tbirds AMD may have done a slight change to the capacitive load the chip puts on the signal lines, but that change may have been made to all of the Tbirds. A 100MHz FSB chip won't necesarily work at 133MHz. The multipliers will be different(L1 bridges). The KT133A chipset doesn't support DDR.

I'm still learning this myself, but here's what I know:
If your chip is meant for a 100mhz FSB, then the 133mhz FSB will produce an overclock of %33(good luck-1.2Ghz is REALLY pushing it! probably won't work). Biggs found a thread, at another forum, where somebody couldn't get an Asus KT133A mobo to work at 133 with an unlocked chip meant for 100-they didn't say if unlocking it would solve the problem.
What most overclockers do is "unlock" the CPU's multiplier-you can't do that with Intel chips, which is why AMD is so popular on these boards ;-). This should allow you to experiment with different speeds-your 900mhz CPU should certainly run at 7x133=931, and you might push it over a Gig.

The A revision also adds ATA-100 support.
