hey i was looking in the bios of my computer and theres this option for hyper transport frequency. it goes up to 5x... what does this doo?

It is basically the bus bandwidth that all the components use to communicate. It should have a max of 1000MHz, so if your HTT is set at 200MHz, then the multiplier should be at 5x. If you overclock and raise your multiplier over 200MHz you should lower it to 4x or 3x to keep the total at or under 1000MHz.
Increasing it over 1000MHz won't increase performance as the components don't use the whole bandwidth available anyway. In most cases it will decrease stability even if slightly over 1000MHz.

So when do you decrease performance ?
I.E Setting the FSB To 150 then Setting the LDT To 3x ?
450 MHZ Transport frequency.. Would that decrease the performance ?
Im just wondering what is ideal to set mine to.
FSB 255 x 4 At the moment

Thanks
This could be the main reason why my pc wont boot at 260+ FSB
Because the Frequency is over 1000

Also the difference between 3x and 5x is a few percent at most and will be lower than the speed increase you get from overclocking.
Don't forget the hyper transport is mainly used for things like SATA, Audio, PCI slots, etc. The bandwidth available at 600Mhz is more than enough for most things, so there's no real need to worry about it - just make sure it's 1000 or less.
Here's a good benchmark of video encoding with the HT at various speeds

I've Oced my system slighty. Its a sempron64 2800, im using a asrock mobo and i couldnt see any HTT multiplier in the bios. Is there any other name for it? as my fsb is now at 275mhz, i dont know what value the HTT multipler is but if its still left at default, surely is well over 1000mhz now?

Maybe on your mobo it is set to auto and it is automatically lowered to 4x or 3xoldhat said:

The overclocking features on that board were very hard to find / adjust i found..
I got rid of mine, because i was too scared to flash the bios to the uber overclocking one lol
