Epox 8KTA3Problems! Shuts off by its self??

[FCBL]

I installed a new 8KTA3 board last night and it won?t boot. I get "FF" on the on board display.

When I turn on the power the board does get power, the CPU fan turns on but no boot up, "FF" is displayed (only code displayed) and the board shuts off by its self in about 10 sections. I have a 300W PS, 1.2 T-bird with 512 memory.

In order to try again I must unplug the main power plug in the mother and plug it back in.
I tried another power supply 650w and the same thing happened except the board does not shut off but the on board display ?flickers? and you here the fan slow down and speed up. It is like the power is being drained somewhere?

I?m also getting the power from a APC unit. APC is working fine. I also tried another computer and it was fine.

Any help would be great!

Thanks

There are, in my experiences, two causes for this.

1. Some aspect fo the video is not proper. Try reseating the card, making sure
the monitor conector is snug and tight to the card.
2. The CPU Fan connector is not proper. try pulling out and reconnecting the cpu
fan connector on the motherboard.
3. The default boot settings for the T-bird (fsb X multiplier) is too much for
the default voltage. This has been discussed at length all over this forum, but
here'sa rundown.

Try:
1. Clear cmos and set the fsbjumper to 100mhz. If you can get to the bios screen
after this, set the multiplier to the lowest possible, and set volatage to 1.8.
Turn off the machine.
2. Set FSB jumper to 133mhz and boot back up. You will now be booting ata low
multiplier x 133mhz bus speed. Go into Bios, and raise the mutliplier to wherer
you want it. Raise the voltage to max (1.85) if you want to.


If that doesn't work, then your only option is to manually unlock the l7 bridges
to set the default voltege value of 1.85. See, the reason the above bios
settings might not work is because even though you set max voltage in the bios,
the cpu boots at default speeds for a millisecond or to before it gets to teh
bios and alters its pfrequencey and multiplier setting. If it can't run at
default voltage, it will never make it to the BIOS.

If you unlock the L7 bridges, I bet you a hundred bucks it will boot.


Hope that helps.

If you are trying to run at the 133MHz bus without changing the multiplier, forget it. Make sure the board jumper is set to 100MHz. In other words, everything set to run at stock speeds.
I'd try this first and make sure it's stable before I go trying to overclock. When you set the jumper on the board to 133MHz operation, it BOOTS at 133MHz right off the bat (or in your case tries to). It does'nt start at 100MHz and allow you to work up from there.

PS the CUP is 1.2 (266)

Email Epox, people have reported quick responces by their tech people. When I first started overclocking, and running into any sort of problems, I beleive I sometimes had the FF displayed, but never did my board auto shut down the entire system, so that part seems odd. If your using several sticks of ram, maybe try them one at a time. Maybe the board does'nt like one of them.
Can you at least get into bios?

 

[FCBL]

Nothing.
Tried other ram as well.
Will Check thier site.

just wondering, what is the chipset on the 8kta3?

 

[FCBL]

133A

My 8KTA3 is doing pretty much the same thing, but i found that if you reset the CMOS it boots fine.

You hvae to reset the CMOS each time you boot, though.

I don't know if this will help you, but i just installed my 8kta3 today and experienced the same problem. tried everything, and it turned out to be the jumper that controlled the RAM STR function needed to be disabled. while setting it up, i had enabled it thinking i might use that function. silly me, i never put my computer in standby. and i was running out of options so i put the jumper back to the default position (off). btw, its the jumper to the left of the floppy connector.

 

[howardthehobo]

So, over all, do you think that 8KTA3 is stable, I mean, I do not want to overclock it, all I care about is it stable or not?

By the way, how is the performance?

If I could get mine working I'd let you know how it performs.

I had the FF Bios code happen...in my case it turned out to be dead CPU (RIP 1.2 Ghz T-Bird). Once I had the new CPU installed it would work but now everytime I try to install Black and White the Installshield Wizard locks up my damned machine. I have tried everything but a different (3rd) processor to see if that is what is causing it. It's starting to get on my damned nerves no matter what it is.

The FF BIOS code means the board is through the post and passed control to the OS.

Make sure JP5, the host clock jumper, is in the 100Mhz position.
Make sure all of the rest of the jumpers, JP1-JP4, are in their factory default positions.
Clear the CMOS and on re-boot load the optimized factory defaults.

When you get to windows go to device manager and disable DMA on your CD drive. I had some trouble loading apps until I did that.

 

[ericd]

Thanks for the DMA tip...I'll try that.
