T-bird 200/266 what the diff?

[bigpig]

I,m seeing theses 266 t-birds for sale what is the differnce. Is it only for the ddr platforms or what. Havent seen any reviews using them either weather it be the new "a" style mobos or the ddr.

the difference is the speed of the FSB. The tbird 266's have 33% more FSB bandwidth (133mhz (266 DDR) instead of 100mhz (200 DDR). They only run at thier full speed on a MoBo capable of the 133mhz FSB, but on such a motherboard, the proformance gains are said to be quite significant. Note that most tbird 200's will work with the higher bus speed if you reduce the multiplier so it is running at the same speed. (ie, buy a 1ghz tbird made for the 100mhz FSB, unlock the multiplier, and change it from 10 to 7.5 and set the fsb to 133)
And there are TONS of reviews using the higher FSB speed, generaly showing a very signifiacnt proformance increse.

The T-Bird 200 runs at 12x100fsb by default and the T-bird 266 runs at 9x133 by default. Not all 1.2 ghz 200 gurantee at 133 fsb, but the 266 version is made to garantee 133 fsb. Hope that helps.
