KT3 Ultra ARU core bus ratio wont work at all

Guest
i have KT3 Ultra ARU mainboard and XP 1900+ prosessor, i try to change bus ration to 14*115, but when i saved settings and boot my computer it wont boot at all (blank screen and leds say prosessor is damaged or not installed properly).
I tryed to clear cmos but main board does not clear settings for multiplier.
If i change another prosessor, boot and change old prosessor back i can make mainboard boot, but is there any easyer way because i do not have that second prosessor any more ;(

If your old CPU is a thunderbird athlon then it is working because the L1's are unlocked. Thats how they came. Athlon XP's are not unlocked so you have to do it yourself if you want to change the multiplier. Im just wondering why you want a 115 bus?????? ?(

Hope this helps. I dont know your situation so im sorry if I look dumb. :D

Hi,

For sure this wasn't the board to blame. Your overclock settings is too much for your system.

Also, when you clear your CMOS,

1. turn off main power
2. wait for 5 mins to let the whole system discharge
3. unplug the main power cord
4. jump the CMOS reset jumper
5. jump back to normal pins
6. plug in the main power cord and turn on the main power

If 5 minutes is not enough, then 10 minutes, or 20 minutes.

Hope this helps.

Yes my old cpu was thunderbird, and i know that L1 is locked. I was trying to unlock L1 but i think some pins wasn't connected too good and when i booted mainboard stuck. ;)
That 115 bus, i tryed that because 115*14 is close to 1600mhz and cpu is not overclocked.

First thanks that helped me, i can now boot my computer again. :))

But i'm sure that is mainboard fault, even manual says "this motherboard is designed to support overclocking"
on the other hand 115*14 is not overclocking, well what ever, i have been plenty of differend mainboards and every single one of them has safe mecanism for this kind of situation (for example when you boot and press insert key all setting cleared).
now in this maindboard i had to take cover off clear cmos, unplug power, wait 20 mins before i can try another settings and that really sucks.

I had exactly the same problem. I played around with the bios settings and tried, just for fun, the multiplier setting on 6. Just to stay on the safe side. I thought. My reward were four red LED's.

Just clearing the CMOS didn't help. At last I removed the backup battery for a night and after reinserting I cleared the CMOS once more but nothing happened. Only thos four red LED's. I'm the the forum is up and running and that Measus posted the answer to the problem. Disconnecting the power cord helped a lot. :))

But I will not touch the multiplier again, not until I dare to unlock my processor.

By the way, I have encountered no problems at all. My system:
new:
KT3 ultra aru (ami 5.4)
Antec case + antec 350W psu
1800+
vulcano 7
twinmos PC2700 ddr (samsung chips)
old:
some HD
some video card

and I can run photoshop with high performance settings, max processor & DDR voltage, FSB 150. Temp of the processor max 41 degrees celsius.
