Connect L1 Bridges on Duron 800

[Miraluka]

Are there different settings like what Tom's Hardware Guide did? or do i simply connect all the L1 bridges? like...changing ::: to ||| . but for all of them? conductive pen is what i will be using.

Well if your mainboard allows you to change multiplier settings (in the BIOS or with jumpers) all you have to do is connect the 4 L1's. If your mainboard doesn't then you need to manually configure the bridges (like on Tom's page) in order to change the multiplier.

i have the MSi K7T Pro2-a mobo, duron 800, and Alpha PAL 6035 with Arctic Silver. The Pro2a has ability to change voltage and clock multiplier in the bios like the Abit boards so i should be able to connect the 4 bridges. thank you for clarifying for me.

 

[Subversal]

Yep just connect them. Hope all goes well on the overclock

I've looked for a conductive pen -- anything has to be better than the pencils (which didn't work) or the rear-window defogger paint (which is too viscous, although I succeeded on sixth try). I've only found the pens for $32 at a specialty Lab supplier. Could someone identify a reasonable source, or the proper term to search for -- "conductive pen" failed to get hits under PriceWatch or StreetPrices.

Thanks!

Radio Shack has a conductive pen in their "extended" catalog. You have to special order it, but the price isn't bad ($8.96 + tax). The catalog # is 910-3890 and it's described as "CircuitWriter Precision Pen, 7ml".

No, I don't have one . But I've considered getting one to use on my recently acquired Duron 750. I'll probably just eventually try a simple mechanical pencil...

I saw somewhere on the boards that the Radio Shack pen does NOT work.

Life is so complicated... it needs a better instruction manual! Is there any concensus on the RadShack pencil???

dude just use the defogger kit..cheap 6 bucks and it works very well

 

[Nelmster]

Did you use a needle to apply the defogger liquid?

 

[Yknot]

I kept going to finer and finer tools, barely succeeding with an old ink-well style of drafting pen which had a nib! Your point is well taken, although I'd find it easier to manipulate something more substantial: next time I'll try using the needle-like foot of an opened drafting compass.

The Problem was that the paint was too thick and it was difficult to make a fine mark -- the paint wanted to Blob rather than draw!

Many art supply stores sell very thin masking tape (less that 1mm). You can mask off between each bridge, apply the repair fluid in less than perfect manner, remove tape after fluid dries, viola !!.

Other suggestions, use the edge of a razor blade as a guide, let the fluid kinda follow the edge. The slightly mashed end of a toothpick is an alternative to a needle. A little practice makes the job easier.

i have a simple way..use a cc and a toothpick. you will need about 10 tootpics. (in case you screw up.)

seperate the bridges with the credit card. dip the tip of tootpick in defogger kit stuff.
wood will absorb quickly so be very patient.

just connect bridges. USE A NEW TOOTPICK FOR EACH BRIDGE.

 

[johneetrash]

wait so the radio shack pens dont work? and how much are those defogger kits usually?

 

[Yknot]

Defogger kits:
$11 at small autoparts store
$ 6 at discount autoparts store (PEP Boys in NJ)

 

[johneetrash]

awesome.. theres a kragen auto shop thingy here so ill hafta check that place out.

Don't you have to do something to the L7 bridges on a duron to raise vol. where a thunderbird you don't

 

[dman]

I imagine the autoparts stores are going to see an increase in the number of defogger repair kit sales this year and the car manufacturers will probably get wind of it and soon defoggers will become standard on all vehicles--all because we are OC'ing durons.

(OK, probably not that many people to make a difference, but, it would be funny!)

tjll11a - The L7 bridging is appropriate for Voltage setting, but is unnecessary if you have an ABit KT7* as voltage is an option regardless of CPU bridges. I presume there are other boards which don't require L7 unlocking as well.

L1 bridging is required for multiplier opening on all boards that I know of: the boards allow one to set any multiplier below the bridged value, so if one shorts all the bridges your chips supports up to the AMD max.

Do a google-search on "L1 L7 Duron" and you'll hit one of the descriptions of the bridging if you're further interested. Tomshardware had the first description of this that I recall.

Sorry, but your discovery of this must have been quite late. The Christopher Columbus of the use of the Duron/Tbird "bridges" for settings was Armand Hirt. IT ALL BEGAN with Armand's ingenious discovery of a correlation between open/closed bridge "patterns" and AMD settings data in datasheets, posted at aceshardware.com general forum. We picked it up from Armand. Tom LATER furnished "one clue", but no details or decoding. No way was the "great one" first.;-)

Discovery timeline is documented at http://members.nbci.com/candjac/index.htm detailed Duron OC article.
