I just bought an amd 2400xp hoping with the chaintech nforce boards hoping that it would be a litte faster... My previous sysetem was a p4 1.8a oced to 2.533 and when runnign my athlon at xp2800 speeds compleatly tweaked i get about 12000 3d marks and when i ran my p4 at 2.533 i get 12800. This really bothers me since the xp rating is 2800 when it boots up and this motherboard is definatly better than my msi 645dx ... why the ... does an athlon spec at 2800xp run slower than a p4 2.533? everything else in the system is the same.
That's the nature of the beast. Paying more for a more expensive chipset doesn't make it better, the 645DX is a stellar performer at it's rated speeds. The P4 2.53 and 2.8 are close in performance, cross over to AMD and a 2800+ being fairly close to a 2.8, I wouldn't have expected it to be slower, but not much faster either.

What also bothers me is i feel like this chaintech bios is a piece of crap. When i run it at some lower multipliers such as 13.5 it boots and others at 13 and 14, 14.5 it does'nt leaving the fsb at 266MHZ. I also can ruin the multiplyers at 15 and 16 but thats it. I also cant get this beast to boot at a 333MHZ buss even with the multiplyier set to 13. Right now im runnig my comp at 142FSB X 16
why the ... does an athlon spec at 2800xp run slower than a p4 2.533?
Well you are also only using one benchmark. Benchmarks don't relate too well to real world performance unless you take a lot of different benchmarks and average them. Does the computer seem slower?
It very well could be slower, but I just wouldn't worry about one benchmark too much. Especially since both systems are very high end. I wouldn't have tried to upgrade a 2.533 GHz cpu for another 2 years.
U Mentioned nForce chipset......do u mean origianl nForce or is it nForce 2 ???
As for performance in 3D Mark being lower......my guess would be that u dont have something set up right......some little setting that seems insignificant in the BIOS....PLUS ur not running at 333Mhz FSB......so thats another reason why.......
Ya it's the NFORCE2 i am now wondering what is the lowest multiplyier i can set on nforce boards for a axp2400 with out unlocking the lower multiplyiers. The computer seems to run about the same speed but a little bit more stable than my p4 system, this being the main reason for switching.
