Here is the deal I have been running an xp 1700 and then upgraded to a 1800. Both worked fine in my system(described below). The board auto sets the fsb to 100 and it must be changed to 133, no prob untill I got the xp 2000. Now, of course it automatically sets the fsb to 100 but when i manually set it to 133 after the initial post beep, evrything shuts down and i get nothing but a lou irratating beep that never ends. I have tried 2 2000s and verified the 1800 still works. Now on a couple of tries I have gotten almost into windows but not very often. Oh by the way if i leave the fsb at 100 i am fine except that i am running at 1.25ghz.Any ideas?

What kind of power supply? Also, did you check all the other settings in your bios like divider, RAM SPD, etc...

Hey hey I finally got the man himself on this one. Glad to have mr. big. Anyway, the power supply is generic 350w, just says "made for pentium 4". The bios settings seem fine, i checked, its just odd that at anytime i can through an 1700 or 1800 in there and it works but as soon as I put the 2000 in i crap out. Anymore ideas?

I found this at AMD's web site. Notice that the XP2000 is left out. Does that mean that there is a problem using the XP2000 in the Soyo KT400 motherboard?

crap ive never seen that before. i hope there isn't a problem, well, on the other hand i guess that would make me buy a 2200

Another suggestion. When you bought your motherboard was the XP2000 out yet. Maybe you need a bios update to support the XP2000. You might want to contact Soyo tech support before you continue.
If your comfortable with doing it you can try flashing your bios and updating the drivers.

Follow this link to the Soyo download page, and make sure you have the most current BIOS. Call the help center also if you have to, before sending it back or spending more $$

Yeah edgkennys got it there, dont worry about the power supply there Damion I have an Okia (generic) 420watt power supply that is more reliable then my vantec stealth! and the real output is 380w but thats damn good for a 15 buck psu

Alright, thanx Ti and G, thats what i figured, i am going to make sure my bios is up to date. I just kinda figured it would be.

Contact me via PM and I will send you a "performance" bios for that board. It's custom hacked. Run the FSB at 133 but change your multiplier from 12.5 to 12. Ram at SPD. Up the voltage to the CPU just a little. And are you running 1 or 2 sticks of RAM?

EDIT: I looked around a bit and yes, a lot of people are having problems with the Soyo KT400 and XP2000 processor. You cannot run the CPU in Auto, you must manually set the frequency. You can run RAM in SPD. There is a B5 bios out that is supposed to allow 2100+ and under CPUs run more stable. Try all this and let me know what happens.
