How do I know that I closed all the L1 bridges on my CPU !?

[MowSow]

I am building this system below, and that is the first system I build. I will be using the rear window defogger solution to unlock the CPU. I will be doing in the few minutes and I will be killing this system, since I an reusing this case, and I wana be able to go back to all of you, happy, safe and sound in a few hours ... any advice is appreciated before I format this hard drive ...
Thanks
PS current system is a 200MMX

you know that you closed all of the L1 bridges if you can change the multiplier

Well first thing I would do is make sure everything is running @ the default speed before clocking it up. (Of course you'll need to have unlocked the CPU before installing the HeatSync)
Just get everything running correctly then start changing the clock multiplyer up or down & if the L1 bridges are connected everything should work.
Just don't get too greedy.

MowSow et al,
Excellent question...more people should have asked.

Not 'completely" true...if any L1 bridge is still open you will be able to change FSB Multiplier, but won't be able to change to "every setting"...you wont be able to affect the "Adder' controlled by any open L1 bridge...see link.

To test closure of L1 bridges before running without damaging the closing material, see page 2 of Duron/Tbird OC article at http://members.nbci.com/candjac/index.htm

To test closure of L1 bridges after running, test underclocking at FSB Multipliers that change all 4 of the default settings of .5X, 1X, 2X, 4X, "Adders". You will understand after you read the article...it's a very simple algorithm/formula for FSB Multiplier instead of incomprehensible "tables". Enjoy.
