1.1 Ghz T-Birds on ABit KT7A-RAID

[boy219]

Hi, I just bought a new system and I'm kindve new at this setup thing. I bought a 1.1 GHz t-bird and I was wondering if its ok to set the fsb at 133 Mhz instead of 100 Mhz. The specifications of the CPU claims to support the 133 Mhz bus. But say if i set it at 133 Mhz (I havent tried this yet) and set the multiplier at x8.5, it would set the cpu at 1133 mhz right? would that be a problem? I just need to know what I should watch out for and what I might need.

here's my system setup if it helps:
Abit KT7A-RAID
1.1 Ghz
256mb PC133
45 gb ATA100
GeForce 2 MX
SB live

one last small sidenote.. I'm not into overclocking yet, so just give me info on my current issue. thanks

1133 isn't much of an overclock for that chip, it should be able to handle it fine. You might have to raise the voltage by 0.025, but it should be easy enough. Nice system :-)

KT7RAID Have SoftMenu III, so drop a multiplier down to 5x for safety and then try to rise a FSB.

On my KT7 , TB-750 @ 1000 I tried to do this but the system hangs! The first and the last solution was to clear the CMOS with jumper! Also FSB+ had no effect - the same hang!
So expect everything.

Oh yeah, do you know you have to connect the L1 bridges on the chip with a pencil or something else conductive to be able to change the multiplier in softmenu - here's an article with pictures, ignore what he says just do the L1's: http://www4.tomshardware.com/cpu/00q3/000711/index.html

Which picture? Where is teh L1 bridge. The pic showing the conductive pen seems to be on the back of the CPU.

[Rob Cork]

Look at the big picture on the first page of the article - the 'bridges' are circled in yellow. The L1 bridges are located on the top right, labelled 'L1' helpfully enough :-)

[castcore]

So you connect l1 to L2? or just the L1 to the first notch. Sorry for sounding dumb but I am actually an experienced Intel overclocker taking my first shot with a Tbird.

If you se the FSB to 133 the computer will hang!
Change the multiplayer instead to 12 for example that will give you 1.2 GHz
The thing you have to do is to connect the L1 bridges on the back of the CPU and reboot and change the multiplayer like you change the FSB
I did it with a regular 0.5mm pencill but its hard to make it good and I dont recomend it.. Use a c-pen instead.

Look, the whole deal about getting a new KT133A chipset was the synchronous FSB and Memory, right...why someone would tell you to leave the fsb at 100 and increase the multiplier to 12 is beyond me... there is an obvious performance hinderance when running a t-bird at 100MHz

connect the L1 bridges and try 8.5x133 or even 9x133=1200 (the cpu should handle it if you increase the voltage a bit.--even if it does hang at startup, the performance gain of 133MHz system bus is worth it
