Can't get multiplier to change

I have a question...

I have an 800Mhz Tbird, but right now I can only get 880 out of it ( 110 x 8 )

The multiplier value is not having an affect if I change it. When I set it to 9 in Softmenu 3, it still shows as 8 after reboot.

What is the deal?

Did I not get all the bridges closed??????

Well I went and re-did the pencil trick....but

I am now able to get the multiplier changed, but even with 8.5 for my ( 800 ) it locks up in windows98 fairly quickly. I up the Voltage with no help.

Am I at the limit, or is it possible I didn't get the bridges closed that good?

Anyone know what happens if you don't get all of the L1 bridges or the cross over to another bridge?

Strike.
 
All connecting the bridges does is unlock the multiplier and voltage. Trying setting your bus speed to host (100mhz) and see if it works. Set hte voltage at 1.85 and work your way up through the multipliers


 
To me, it seems like that it could be of two problems:
1) Heat: This may be an issue if you are using stock cooling, so but either way, you should check the temperature and see what it is.

2) The bridges may not be connected well. For some reason or another, it seems that the chips OC better if the bridges are done better. Perhaps you can get farther with something a bit more conductive than a pencil. I say that you should at least try repenciling in the bridges.
 

Thanks Paulip88,

That is my intent. I bought a magnifying glass, conductive micro pen, and have been looking at better fans. TaiSol's looks good for only $11 bucks, and AMD approved up to 1.1Gig.

Actually, I have not noticed any difference when using other methods than the pencil trick, as the only time the L1 bridges are checked is during the boot-up. My guess is that there is a problem other than you chip, although 850 is the max for some of AMDs cpus. I would check for driver related problems, perhaps a video card that is overclocked too far. I would also make sure there is a good contact between the cpu + heatsink and that the interface material is in good condition. You may want to underclock your memory or slow down the timings. Also it may be helpful to increase the CPU drive strength and other such things in BIOS. Good Luck

After getting a magnifing glass and finding my mechanical pencil, I tried it again and got lots better results. ( I have read about others having to try it more than once to get stable performance ).

The second, time it changed, but way unstable. Third time was the charm...

Strike 😀
 
Fish54,

about your comment about the pencil bridges only being a factor at bootup, I'm not sure that that is absolutely true. It makes perfect sense to think that, but I still have to disagree with you.

When I was doing the pencil trick, I would be able to POST at up to 950MHz. However, it would not run stable above 808MHz (8x multiplier).

Currently, I have switched to the conductive compound in a conductive epoxy used for repairing window defoggers. Using this, I can run stable at 850MHz, which is 50MHz more.

This is the exact same setup. Only difference is the material used to connect the bridges. No I don't know why. I just know this ismy experience.
