L12 mod for 1700+

Just a quick question, well a few questions. Main question does the "U" shaped wire go into the socket itself or on the CPU pins? Secondly, what size wire should be implemented?

I think you are asking the question about how to set the default FSB of a CPU such as 1700+ which has default FSB of 133 MHz to 166 MHz, or even 200 MHz.

Link: FSB_Sense mod to set Tbred B default FSB from 133 to 166, or to 200 (http://forum.oc-forums.com/vb/showthread.php?s=&postid=2004978#post2004978)

I call this FSB_Sense mod becuase it uses a U-shape wire, instead of altering L12 bridge (even both should have the same effect if done correctly).

There are two ways to do that:

1. Physically alter the L12 bridge which is an (almost) irreversible process.

2. By putting a U-shape tiny wire INTO certain pair of holes of the CPU socket, when the socket lever is up and before putting the CPU in. In doing so, in general, one could connect two specific near-by pins by that U-shape tiny wire to do certain things, such as setting default Vcore, and in this case setting default FSB from 133 MHz to 166 MHz or 200 MHz, depending on which pair(s) of holes.

The advantage of the U-shape tiny wire trick is that it can be added or removed at any time. It has to be done very very carefully, double check the work. Putting into the wrong holes might kill a motherboard and CPU. Also don't let any metal debris such as that from the wire cutting or else drops on the motherboard and/or the socket.

As far as the size of the tiny wire, it has to be very thin and tiny. I usually cut a single strand of wire from a 20 AWG size wire which consists of 19 strands of wire, and make a tiny U-shape wire with length about 3 mm each leg. Without going into the actual size calculation and specification, the diameter of a strand of wire is about 0.1-0.2 mm. The main reason is that the wire has to be thin enough so that after one tiny U-shape wire is put into the two socket holes, there is still enough room for the CPU pin.

In some case which I have done, a single CPU socket hole may have to share with two tiny U-shape wires, and still have room for the CPU pin. E.g. the AH32 hole for FSB_Sense mod for FSB 200.

Thanx hitechjb1 :clap:
