L6 bridge connecting

[Tanus]

I am currently running an Iwill KK266 with a duron 800 with fop-32 cooling. The machine wont post when i change to running at 133 fsb, which isnt unexpected, and wont post when i lower the multiplier in bios due to the motherboard taking the default multiplier for the first few clock cycles til bios takes over.

I am wanting to run with the lower multiplier+higher fsb for the obvious performance gain. I tried pencilling in the appropriate L6 bridge as per the http://www.anandtech.com/showdoc.html?i=1440&p=6 article, to lower the multiplier to 7. However, it still wouldnt post. Is there something else that i should be changing also? vcore default adjustment?

so... noone has any ideas?

if you connected the right L6 bridges it should default at a multiplier of 7 x 133 is 933 so im supprised it doesnt post.

but.... you can always connect the L7 bridges this will increase the default core voltage. maybe at 7x133@1.85 it will be able to initialize long enough for the bios to load your new "user defined" settings

good luck

here is another link that im more familiar with in how to get the correct L6 setting

I thought that it was the L1 bridges that you were supposed to connect. THats what I did on my 1g, and it worked fine.

L1 unlocks the cpu, and thats probably all you needed to do

the problem is boards that are totally jumperless except for one jumper to switch from 100 to 133mhz like the kk266 and 8kta3 and still its only a problem if you want to run a duron or tbird (200) on a 133mhz bus.

because it tries to initialize at the default multiplier but on a 133mhz bus

example a duron 900 that you want to run on a 133mhz bus will need to initialize not at 9x100 but at 9x133 or 1.2ghz if the cpu cant initialize at that speed then the system wont boot long enough for the bios settings to kick in and drop the multiplier down

boards that change the fsb and the multiplier at the same time (either totally jumperfree or totally jumpered) have no problem running chips designed for 100mhz at 133mhz

If you want to change the multiplier by setting it on the chip alone, you must also modify the L3 and L4 bridges.

 

[Boonesmi]

adam is right, you can use just the L6 to drop the default multiplier so the board can initialize then load your user defined settings,

but.... if you want to actually run the chip at at default settings you need to change L6 L4 L3
like adam said

I did of course try it at 7x100 first .

I have previously managed to get it to initialise to bios then dropping the multiplier when running on the 133mhz bus, but that would be a 1/10 occurence, so the chip should be good for 930. I'll take a look through the link and play with default vcore settings.. thanks for the help
