Epox 8KTA3 OC help needed...pls

[Fermium]

Hi guys... I just bought a Epox 8KTA3 (no +) ... at the box... it's say it support 200/266 FSB CPU.... but when I try to change the FSB settings in CMOS.... I found that the highest I can go is only 120/240 and the Core Voltage also only maximum of 1.850

( I'm using a Duron 750... is this bcoz it auto-detect that my CPU using 200FSB... how to correct this? ... or is it bcoz I've been somehow been cheated : it should be a KT133A chipset that support 266 right, while what i have is only KT133 (no A)? )

Or do I need to update my CMOS? but when i boot up cmos message show that it support KT133A chipset.

Please help me guys... for your information... I crushed my system and have to reinstall everything... yeah blue screen of death. by the way... this is my first time of OC.... really hope u guys can give me some advice...

again... thanks for your time and knowledge...

You do know there is a jumper on the board to switch from 100 to 133 fsb right?
Heres the trick with the Epox board, that I found to work for me on 100fsb chips running at 133.

First, set the multiplier really low, like to 5 or so, then, save settings in bios, and reboot.
Once you have posted at the new lower speed, shut down again.
Switch off the power supply, move the Jumper on the board to the 133mhz position.
Start up the computer, and you should now post at a default 133mhz speed. Go into bios, and you will now notice that you have settings from 130- 166mhz on the FSB to pick from.
Mine chugs along at a 150fsb using Kingmax pc150 memory set at Cas2 on a tbird900@1050.
