260 Yen(2$) Sweet temptations

The stability of the DUAL PEN III machine is very good, don't you think?
The remodeling work does not end there.

Commemorating the tremendous hit received, so far around 20000 cases, a further remodeling is planned using only 260 Yen, which is aimed at overclocking the BP6.
This time the danger of damaging the motherboard with over-specifications is high as compared to the previous modifications; please work prudently, the author shall not be held liable for any damages incurred from following the modification.

Remodeling the V3.3 line

The latest remodeling this time will be the Vio, which is a 3.3V line. Don’t u think it’s interesting? The 3.3V of the ExCraft adapter, which I had, is able to supply 3.5V in the 3.3V line. As for the BP6 applying a Vio of 3.5 V in ATX 3.3V, not possible? In this case it is possible because the internal 3.3V unlike with other motherboards, is formed from the 5V supply. So this time it will advance type of remodeling.

Components involved!

First, from Akiba, the following ones are gathered.

2 x 5kW variable resistors (100 Yen) and 2 x 10kW precision resistors (1/4W 30 Yen) all for 260 Yen, damn cheap!

Preliminary arrangements of the resistors

Next, the variable resistor and precision resistor are bound together as shown below. The universal base plate is possible to do without and with that an economized remodeling is achieved.

2 of the pins of the variable resistor are shorted together via the 10k resistor. After securing the 10k resistor to the variable resistor, solder them together and cut off the excess pin as shown below.

Next, you measure between these two-pin with a multimeter and adjust the resistance to 2.5kW. Mark this point with a marker. Do the same for the point with the maximum resistance.

As the joints are exposed used gummed cloth tape for insulation.

Processing the motherboard

The formation department of 3.3V is processed. In order for proper overclocking to be achieved, it is necessary to modify the reference value of the resistance to the regulator; this is to increase the 3.3V to 3.6V range. In order not to apply excessive voltage, the value of the resistance is adjusted only once and is done through careful adjustment. The largest voltage that can be applied is approximately 3.9V. Please do not be stingy and skip the 10kW precision resistors and just do this modification with the variable resistor. It is ok but you may end up destroying your motherboard just by trying to save that 60 Yen!

Tip for the removal of the XR15 and R116 resistors.
This method of removal came off the BBS some days ago. It involves heating a pincer over a gas cook stove and then pinching directly at the resistors. Don't you think it is enormously good method? Thanks go to the guy who came up with the idea.

The XR15 is removed.

The R116 is removed.

Installation to motherboard

Well, the resistors will be installed in the motherboard. Just that it’s a little too narrow. Just bend the pins a little ahead.

Now you have to solder them to the motherboard.

Connect the ATX power supply to the motherboard without the rest of the components e.g. CPU, memory etc. Just the bare board with the ATX power supply attached with electricity being supplied to the power supply.

Voltage adjustment is achieved with respect to the reference voltage being supplied to the regulator. In other words, by coupling resistance and adjust the resistance, the reference voltage to the regulators will also be synthesized. As the CPU isn’t inserted the load to the regulator will be light, so in this way you can adjust Vio. Voltage across regulator Q12 is measured. Using a Philips test-pen or a small minus head screwdriver, start adjusting the variable resistor (VR). As the normal value of Vio is 3.37V, try setting it to 3.57 V a rise of about 0.2V. Slowly turn the VR with your screw until it reaches 3.57V.

Voltage is measured across the regulator Q17. In this case, it should not read 3.37V because of the adjustment at Q12. Keep turning the VR slowly, till the reading reaches 3.57V. With this way it becomes 3.57V. Take note not to over set the voltage.

Time to startup!

Time to start it.
Alas I cannot put in the AGP card.
The installation of the VR is horrible don’t you think?

Why cause it may block the insertion of some AGP cards.

Wiring the VR to motherboard

Well who says it was easy the first time? In this case a simple mistaken was committed.

By resolving the mistake the modification became as shown below.

With that solved put in the video card, ram, CPU and keyboard and bootup!
As for the FSB, set it to 110MHz in the BIOS and pray.

Oh my god! You did it! The Boot-up screen shows PIII at 856MHz! What a Beautiful BIOS screen that came out! Don't you think? It appears as 856MHz probably because there is no 880MHz CPU info in the BIOS. If that is the case, Windows 2000 should also be able to start. As expected, with just an adjustment of 0.2V, the effect is large, don't you think?

With that notion in mind, the future is here! Overclocking fantasy! Try using a PIII 600 with 110FSB and it gets you near the performance of a 800EB! So this is good news for those out there who wants to use PIIIs on the BP6 and at the same time want to overclock them.

Locking of the VRs

Clearly letting the VRs dangling around is unsafe and might affect the Vio. With some instantaneous adhesive agent have them fixed to the side of the AGP slot. Is it clear that vinyl line whose wires are soft should be the ones used in this case. They can be peeled off from your regular IDE cables or even your floppy cables you have lying around!

This modification of Vio does not affect memory and even helps to end those startup instabilities! Usually, Vio is not at 3.4V-3.5V but the majority of recent motherboards has it defaulted at 3.5V! Problem with this modification? Think again!

How about setting Vio at 3.7V? Will a FSB of 124MHz work? How far will it go? What are your opinions? How about the results?
