Op Ace's Hardware vond ik een zeer interessant stukje nieuws, daar is iemand die zegt dat je met behulp van wat gekloot met de pinnetjes op de Thunderbird de multiplier kan instellen . Tot hoever dit correct is weet ik niet, ik kan het namelijk niet zelf testen, maar als het klopt is het zeker goed nieuws voor tweakers die er over denken om een Thunderbird of Duron aan te schaffen:
Some time ago, I mentioned the possibility of altering the golden bridges on the Tbird and Duron packaging to change the CPU bus multiplicator. While I still have no clue about whether or not it is possible in practice, I discovered something potentially interesting that I want to share.
Look at these pictures of a Duron 700 and a TBird 1000, resp.
Consider the group of golden bridges labelled "L6".
Duron 700 : 1 0 0 0 (top down) TBird 1000: 1 1 1 0
Now, please turn you attention to AMD TBird tech doc page 62.
You will notice that these sequences correspond to a multiplier of respectively 7 and 10. This could indicate that group "L6" controls the bus multiplier. A sure way to verify this would be to use a sharp pen with a soft tip, and connect all the bridges in the L6 group of a TBird 1000. If the hypothesis is correct, it will be recognised as a TBird 1100! If not, of course, the part may fail, and at this point you had better erase the traces you have just drawn. BTW, Anand has a picture of a Duron 800 and the mulitpliers are interpreted as being 8 in this hypothesis ( 1 0 1 0 ). I do not know about you, but if I had a TBird handy, I would try something.
But what if it does not boot because of the voltage? Then turn your attention to group L7.
Duron 700 : 0 1 1 1 0 (bottom up) TBird 1000: 0 0 0 1 0
While the Duron 700 setting seems to correspong to 1.5 V, the expected setting, the Tbird 1000 would be 1.8 V (which is 0.05 V up from AMD specifications). This said, still in this frame of interpretation, Anand TBird 800 settings ( 0 0 1 1 0 ) correspond to 1.7 V, the expected setting.
The second part is less convincing because of the issue of the Tbird 1000, but all in all I think this is pretty interesting. Tweak on?
