EPoX 8KHA+ FAQ

I have a 266FSB CPU and set it to run at 266FSB in the BIOS but I am running at 200FSB how can I fix this?

Most Likely you have CPU host clock select jumper on pin 1-2, you need to move it to pin 2-3 this jumper is located just to the left of the AGP slot.

I changed some settings in my BIOS now my computer will not post.

The best thing to do in this situation is to clear your CMOS, doing this will reset the CMOS to the factory default settings. To do this find the CMOS clear jumper which is right above the battery, move it to pin 2-3 and leave it there for a few seconds then move it back to pin 1-2. Restart you computer and it should now POST, you should go back into your BIOS and load the optimized defaults.

What are these red letters and numbers on the motherboard?

This is the P80P Debug (POST) card it is a diagnostic tool which displays hexadecimal POST codes which can help in troubleshooting. Refer to your motherboard manual on what the codes mean.

Why is my computer running really slow with this motherboard?

You need to be sure and install the newest 4-in-1 drivers from VIA which can be downloaded here. These will give you the boost you need.

I want to turn my CPU Vcore up higher than 1.85v but that’s as high as it goes in the BIOS.

There is no BIOS fix for this, if you want to push your Vcore setting higher than 1.85v you will need to do a Vcore mod. I have written a guide on how to do this which can be seen here

Will an Alpha PAL8045 fit on my EPoX 8KHA+?

Yes, it will fit fine without having to modify anything.

How can I fix the “soft reboot problem” which occurs when I have my FSB above 150?

The best and easiest way to do this is to flash your BIOS to one of the newest version or even a beta BIOS doing this should fix the problem.

I want to flash my BIOS how do I go about doing this?

The best way to flash your BIOS is to first get a disk and format it, after you have done that download the BIOS update you would like to use from EPoX. Extract the .BIN to the formatted disk and put it in your floppy drive. Reboot your computer and when the computer is POSTing hold down ALT+F2 and the motherboard will take over and flash your BIOS for you. I really like this feature which is built into EPoX motherboards it makes things a lot easier.


What should my settings be in the DRAM Clock/Drive Control section for the best performance?

As long as you have good DDR and it can support it here are the best settings for this section, if your system cannot handle these settings you may encounter errors. If this happens change the System Perforce to a lower setting.

System Performance: Turbo
Current FSB frequency: 133Mhz
Current DRAM frequency: 133Mhz
DRAM Clock: 133Mhz
DRAM Timing: Manual
SDRAM Cycle Length: 2
Bank interleave: 4 Bank
DRAM PreChrg to Act CMD: 2T
DRAM Act to PreGhrg CMD: 5T
DRAM Active to CMD: 2T
DRAM Burst Length: 8
DRAM Queue Depth: 4 Level
DRAM Drive Strength: Auto
DRAM Drive Control 1: 04
DRAM Drive Control 2: 04
DRAM Command Rate: 1T Command
DCLKI Timing: 0 ns
DCLK0 Timing: 0 ns
Fast R-W Turn Around: Enabled
Continuous DRAM Request: Enabled

What should my settings be in the AGP & P2P Bridge Control section for the best performance?

This will also vary from system to system but with newer cards this is how it should all be set. If your cannot handle these settings decrease them.

AGP Aperture Size: This should be whatever half of your system RAM is
AGP Mode: 4x
AGP Driving Control: Auto
AGP Driving Value: DA
AGP Fast Write: Enabled
AGP Master 1 WS Write: Enabled
AGP Master 1 WS Read: Enabled
