right now i have my new athlon 64 3000+ socket 939 clocked at 2.43ghz with a multiplier of 3x and ram at 270mhz my qestion is since that puts the hyper transport at 1620mhz would it be smarter to drop the ram down to around 250-255mhz and put the multiplier at 4x so its at or just above 2000mhz?

According to my calculation 3x270=810
You're fine, when you go to high your PC will let you know

well i know that thats y i dont have it set to 275mhz cause after some benchmarks the cpu would overheat and restart the computer so i backed down to 270mhz and everything is fine but i was wondering if i would get better performance off of 270mhz and 3x ht which comes out to a htb of 1620mhz or if i would get better performance off of 255mhz at 4x ht which would come out to htb of 2040mhz

You're leaving out the CPU multiplier, 3x270= 810 thats the hyper transport rate, plus 9 (CPU multiplier)x270=2430mhz the CPU speed.
Hyper Transport and CPU speed are separate. You could raise the HT multiplier to 4 and the HT would be 4x270=1080 and if you leave the CPU @9 it'll still be running at 2430mhz, if you lower the CPU to 8 then 8x270=2160 and the HT would stay the same @1080.

lol yes i know all about that but what im asking about is the hyper transport bus because it is able to run at or a little bit above 1000 i dont think it would be stable at 1080 so i was askin because i dont know so much about hyper transport bus is that would my computer perform better at 270mhz ram and 3x hyper transport or 255mhz ram and 4x hyper transport

If your PC is stable @3x270 HT and CPU @9x270 then that would be best, as long as heat isn't a problem.
Use S&M to test system for stability.
Warning! S&M gets things really hot, download SpeedFan and use it with S&M to monitor heat and voltage.
