is it easier to overclock using the bios or fuzzy logic 4? the later doesn't seem to work.
what's the max settings and most stable as i see people o/c 1700's to 2600's!!! wow!!!!
i have an msi kt3 ultra mobo with 728 meg of ram.
how do i do it, and do it safely!!!!![]()

There are 4 different types of XP2000+ which make a big diff to o/c'ing attempts.
To determine which core you use you can either look at the markings on the CPU or try using Windows sw. Eg typing SET at DOS/CMD prompt and look at Family, Model and Stepping numbers. If the CPU is locked then you can't alter the multiplier so are left with FSB only, that can throw your RAM/PCI/AGP/IDE all out of spec. You have a KT333 mobo, almost always 266FSB only, usually stable up to 288FSB but PC2100 may limit that. Please give us full system details and CPU info and we can go from there.
Voltage plays an important role in how far you can o/c, but it's often the most dangerous thing to mess with. Basically TbredA/B should use 1.65v, that's normal voltage but it's likely AMD use a lower voltage for the lower speed XP, setting 1.65v for your CPU is a good start. It's best to keep RAM running synced (equal to FSB speed) at least until you see how far your CPU can go. If it's locked simply up the FSB a bit at a time and test you're stable. When you hit a limit you need to think whether it's cooling, RAM, PCI/AGP or something else limiting you. So long as your RAM is running within its spec (ie < 333mhz for PC2700) and at normal timings it should not be a factor. PCI should be fine up to 36mhz (33mhz is normal) but will vary depending on card used. So long as you're sure it isn't cooling you can up the voltage by 0.05v and see if it helps, it should so keep upping the FSB a little (and test) until you find the limit again. Once again add 0.05v more voltage (usualy precautions) up to 1.70-1.75v to be pretty safe or closer to 1.8v if you want to live on the edge (your risk either way). When you find the max speeds you can attain consider if the extra voltage brought you good enough gains to keep it there, whatever you decide avoid leaving your PC on the ragged edge of an o/c (ie drop back a little from the absolute limit). HTH!
