I am looking for the exact settings to overclock my A7V333 mobo. I have an XP 1900+ unlocked to a 2000+, but anytime I increase the FSB it won't post. I have played with the voltage, but I'm looking for PCB rev., memory settings, bios rev., anything to make this work

Your not providing a lot of necessary information, but try this. (I don't have an ASUS manuel with me so this is from memory). Update your BIOS, I think they are up to about six revisions for this board now. Then in BIOS, 1. Set your CPU speed to "Manual" 2. Don't increase your CPU Freq multiple at this time. (Up this later on) 3. Pick a number and set your CPU/PCI freq. (This is also called the FSB). I usually start with 150/38 ??? or so. 4. Set your CPU/Memory to 1:1 --------------------------- If everything works and it boots into Windows start over again and increase the CPU/PCI freq higher. What you are doing is seeing what the limits are on the CPU/PCI. When that limit is found drop down just a little (I usually drop down about 3Mhz) and start upping your CPU Freq multiple. When you run into a wall with that, back off slightly. Next start playing with your CPU/Memory Ratio. If I remember correctly your settings are "Auto", 1:1, 3:4, 4:3, 4:5, and 5:4. Once these settings are determined then you will need to fine tune everything. This is when you start to play with voltages, memory latency etc. This ought to provide some entertainment for several weeks for you. It takes some expermenting to get the maximum out of it. Remember the most improtant thing is to only change one thing at a time. That way if it doesn't work then you know what didn't work. ASUS has two things to be aware of. One is that if it doesn't post, it will reset itself, and you can restart it. BUT NEVER, NEVER, NEVER, TURN THE POWER OFF WHEN YOU ARE IN THE BIOS. If your computer locks up on you while you are in the BIOS, LEAVE IT ALONE, FOR AT LEAST 24 HOURS. (It may take that long to come out of its trance). If you don't then you may be sending your BIOS chip to BadFlash for flashing. I learned the hard way, after i turned the power off in BIOS the 3d tome. I got away with it the first two times. }:-( But now I have some extra BIOS chips.

Thanks for the info, but all stuff I knew and have tried. I actually own a computer business and have overclocked many a system, this one is just being stubborn.

I think until now the 1006 BIOS is best... I don't have an Athlon XP running on my system, maybe a later BIOS will be better. I'vo got a Athlon 1000MHz running @1481MHz (141MHz FSB; CPU/Memory ratio 4:5, 1,80V) with "turbo" settings - I'm still trying but it's always better to leave the settings on "auto" if possible... Good luck!
