TBird 200 or 266 FSB?

[Fermium]

Hi Guys, does any of you know which Tbird is better performance and more overclockable? the Athlon-C with officially use 266 FSB or those with 200FSB?

Thanks for your time and knowledge.

I have read somewhere that the 266 is a slightly better OC'er. I can't verify this though.

I think that the 266 Athlon - C s use copper interconnects so will OC better - Aluminium has its limits.

I have not seen a definitive, scientifically conducted, head-to-head shootout between the 1.3/200 and 1.33/266 Tbirds. It sure would be nice to see a pair of them, with the same stepping code (or as close as possible) in the same system, tested for maximum OC with attention to maximum multiplier, maximum FSB and of course, maximum total speed. I realize that at the top end of the process, the vagaries of individual chips come into play. Still, it would be one of the more informative articles to read, yet no one seems to be picking up the ball. If, as I suspect, the two have the same core, with the only difference being the coding of the bridges on the surface, then the 1.3/200 would be a much better value than the 1.33/266 since it sells for about $20 less. So, any Philanthropists out there? Any OC sites with deep hardware budget pockets? Any reseller want to loan me the two for an evaluation?

I'm thinking that all the 1.2 and above cores are all the same with different numbers stamped on them. I have a 200 1.2, a 266 1.2 and a 1.33 all AXIA and are getting virtually the same exact results on one of my KT7A raid boards. These chips will only get to 1480 mhz, they run exactly the same temps under load at the same speeds, They are identical in every respect except the markings on the top. I'm thinkin AMD just made a bunch of cores and just stamped them with whatever stamp had ink in it at the time.

I would tend to agree, although I did have a better overclock out of the 1.2(266) before it cracked. At default voltage, it would hit 1500(10x150) and 1507(11x137) with good stability. The 1.33 I replaced it with has a very hard time maintaining 1507, even at 1.85v.
