Thanks all !

I will try one more time tonight.

Try redo the pencil work on the L1 Cache. You can use eraser to take the previous lead off. Let just hope that it will work or there could be something wrong with you motherboard.

I agree - is your KK a rev 1.2 board ? If so, then check whether it has the notoriously missing transistor.

Yo

Elaborate please mom :)

Some of the IWill rev. 1.2 boards were missing a resistor or two, which resulted in them not booting at 133MHz or not allowing to change the multiplier. IWill acknowledged their snafu in late February and implemented an RMA program.

More information is on the IWill website or here in some older posts.

I can changed the multiplier in the bios to 9.5 or 10X100 and it works. Would this work if that was the case?

Thanks,

It works !!!

I redone my L1 bridge, and now I can do up to 7.5 X133 which gives me right at 1000. It gets unstable at 8 X 133.

That's good to hear Tbone. Do you plan to raise the FSB a bit more to increase performance, like 7.5X140=1050 with 1.80V-1.85V or 7X143= 1001. I see you have good quality ram, you might want to try it sometimes.
 
yes I might try that tonight. You do that in the bios settings right?
Or there anymore settings in the bios I should look at to change from the default settings?
 
Right, the cpu multiplier , the fsb and the vcore adjustment are all in the Iwill Smart setting. In the Advanced Chipset Features is where you set the SDRAM CAS Latercy Time to 2 and the DRAM Speed to the fastest. This link can help you set up the bios, http://fullon3d.com/kk266faq/kk266faq.shtml

Looks like your cpu speed can go much higher, if you haven't even touched the vcore. Keep you eyes on the temperture. The Idle temp usually around 40C in the day and cooler at night if using a 26cfm fan.

Yes, first max out the memory settings, and make sure it's still stable at 133, then reduce multiplier and take it up to 140FSB and likely 150.

You may also want to improve cooling.

Last night I changed my CAS to 2, and the memory settings to the fastest setting. all working well. Temp is running at a 40C.
Tonight I will raise my FSB some.

later
 
I'm running fine at 7.5 X 140 = 1050

I'm happy with this for now.

What exactly did you do? I'm having similar problems as you, except I got a 1.3 (200fsb) tbird
I can't get mobo to even post @ 133.
 
Aftershock, you need to lower the cpu multiplier in the bios to something like 10X or lower and boot it inside windows once with the 100MHz fsb bus (10X100=1GHz). Next, shut down and switch the fsb jumper to 133MHz. This time it will boot at (10X133=1.33GHz), you can now set up the multipler and fsb the way you like, remember one thing when you overclock too high and lock up the system and you need to use the cmos, the default 13X multiplier will come back (13X133MHz=no boot), all you need to do is switch back to 100MHz fsb and repeat the procedure. Have fun.
 
Doesn't the KK266 initialize always by default clock speed x FSB jumper

so if I wanted to get 133, or even 140
it would have to boot as 13x133 = 1729

looks like the only way is to close up the L6 bridges to hardwire it more voltaget for it to start up for that brief second....don't think I'll be doing that.

when FSB=100 the PCI is 1/3, when jumper is 133 PCI is 1/4 right?
so 107 FSB +33 ram (107+33=140) should yeild the roughtly SAME performace as 140 FSB right? Assuming we could get a matching clock speed.
 
The KK266 initialize by the default clock speed and fsb of your TBird. If you have a TBird 1.33GHz 266MHz fsb, the default would be 10X133=1333 and shouldn't have any problem booting at 133MHz fsb because of the lower multiplier. TBird 1.3GHz 200MHz fsb is 13X100=1300 by default. When you use the 133MHz fsb and lower multiplier to 10, it's consider overclocking already. 13X133MHz=overclocking failed without voltage mod and extreme cooling or you don't have a 1.7GHz 266MHz fsb palomino :)

when FSB=100 the PCI is 1/3, when jumper is 133 PCI is 1/4 right? Right.
so 107 FSB +33 ram (107+33=140) should yeild the roughtly SAME performace as 140 FSB right? Assuming we could get a matching clock speed.

The HCLK+33 setting use a ratio of 4/3=1.33.
At 100MHz X 1.33=133MHz memory speed, not system bus speed. The fsb is still 200MHz.

At 107MHz X 1.33=142MHz memory speed. The performance increase is only on the memory and not the fsb, 214/142MHz.

The 133MHz FSB should has slightly better performance, The system bus and the memory both run at a higher speed, 284/142MHz.

My turn to ask, did you get the Tbird to run at 133MHz?
 
Nomis (Apr 27, 2001 11:53 p.m.):

I've heard from others that the +33 is really fsb/3, or anotherwords, PCI speed


although using both methods give fairly close answeres.
but I guess just plain +33 speed to ram is way off
 
Okay I used WCPID to confirm the ram speed

looks like HCLK + 33 = host clock + PCI speed
its what all the numbers are pointing to when I check on my ram speed.
 
Maybe you have one of those boards that have a defect and keep posting at 8.5 if you try to change the multiplier.
