Diwswitch issue with powerleap mod HELP PLEASE

[URHA.NET]

hello,
Powerleap PL3Ip/T celly1200 and BE6-2.

i bought all the components (dip switch wires...) and i am going to try to get my celly to run faster.(increasing the vcore)
now i saw several ways on the way that people tried to to the trick of the vcore.
the way i want to do it is by solding the wires to the converter voltage regulator and sold that to the dipswitch.
now my question is how should i sold the cables to the dipswitches?
should i put the vid 0.1,2,3 on each of the legs of the dip switcher?
and then sold the VID25m orthe Vss to the other side of the dipswitch to all the legs?
please help me out of with this one!

It's difficult to help you, without knowing what your switch
looks like. Can you post a picture or diagram of the switch?
You might get more help.

[URHA.NET]

the confussion to me comes where i should attach the wires coming of the converter onto the dipswich.
i think i should connect the VSS the (the wire comming of the board not from the chip) to one side of the dipswitch and connect all legs there, then the four other wires coming from the board to sold them individualy to each dipswish leg.
anyone confirm this

BTW the picture is not mine

[URHA.NET]

Please any help here?
i am desperate!

[doer]

I hope you have a steady hand (not shaking) and a low-wattage soldering iron. (like 20-30W?) I'm not an expert at soldering but u can learn by doing :) Just be PATIENT.

Well I used a dipswitch with 6 switches (of which I used 5).

THIS http://koti.mbnet.fi/~alderan/mod/isot/vid.jpg is the important picture, PRINT it!

AND THIS file, PAGE 21 (you see the voltages), PRINT it!
ftp://download.intel.com/design/celeron/datashts/29859601.pdf

Yes, you connect the other side of dip switch legs together and there you connect the Vss.

And the other side of dipswitch you solder one at a time Vid25, Vid3, Vid2, Vid1, Vid0. (There is only 4 at the www-site picture connected, but use 5 to get all the voltages)

When you switch one switch of dipswitch to ON position, then it gives you 0 as a voltage selector (as in the page 21 picture). When you have it OFF then it gives you 1 as a voltage selector.

AND you MUST cut the vid traces on the adapter with a sharp knife as shown in http://koti.mbnet.fi/~alderan/mod/isot/katkaisu.jpg with red marking. I don't know how deep you've to cut. I maybe got 1-2mm cut... PRINT it!

Remember that you've to cut the "wire endings" only about 1-2 mm open when soldering them to the adapter. Not more, cause otherwise you'll connect them all together. AND check that you haven't soldered them together. AND check that you use really thin wires... and check they bend good so that they won't get disconnected after you recover your adapter with those black covers.

If here is something wrong plz let me know... I haven't soldered that tiny things b4... and I don't guarantee anything, but I did it that way and it works. (the www-site mod is by Alderan, not by me, and Lyron(?) w/ help of Ol'Man did about the same thing @ Overclockers.)

I hope you succeed :)

Hi
i was so desperate and so inpatient last night that i did what thought was right lucky enough i did the right thing.
everything is working fine i indeed used a 30Wsolder and a IDE cable wich i cutted 6 wires from VID connecors and the vcc.
i read the manual of the powersupply chip and saw there the table of voltage setings.
i am now runing at 1.5Ghz on a abit be6-2!!! (1.675V) cas2
i am so happy the soldering went just fine a little bit of melted plastic but ok.
i will put some sillicone on the chip and on the Dip switch so i wont couse a short circuit.
one more question.
How high can i get with my system i got a pci divider of 1/4 and FSB of 150 and a Neng Tyi cooler wich is huge and cools greate.
Thankyou for the Help Doer!
i will post some pictures and a document aout this operation soon.
Regards

I also have a powerleap pl-ip3/t and a tualatin celeron 1.2Ghz.

My motherboard is an ABIT BX6 rev 2.

I am running the CPU find at 103Mhz FSB, but obviously I'd like to push the FSB to at least 124Mhz. To do this I want to up the voltage to 1.675V.

Now from your successes I can modify the powerleap adapter with a dipswitch and control the voltage with that.

But could I not also just connect the VID2 and VID1 pins on the CPU (not the adapter) (see sticky in this forum) to change the default voltage from 1.475 V to 1.675 V?

(Technically all I have to do is connect VID2 on the CPU to either VID0, VID1 or VSS since the last 3 are all connected internally).


However, when I wrap a thing piece of speaker wire (one thread) around the VID2 and VID0 pins on the CPU once, and set the FSB to 112Mhz FSB I get no post, which probably means the volt mod is not working.


Has anyone managed to overclock their tualatin CPU by wrapping the 2 CPU pins, AND uses a powerleap adapter?

[MattR]

I've got the same situation. Trying to o/c the Powerleap/1.2 combination on an MSI 6163 Pro. Both before and after doing the pinhole mod, will run fine @110, boot @ 117, lock up hard @122.

I'm wondering if it's necessary to cut the voltage regulator traces on the adapter to get it to read the voltage from the pin settings, rather than the internal regulator on the adapter. I note that the dipswitch mod apears to require these traces to be cut. Seems logical that the same effect could be accomplished with the wire/pinhole mod, i.e., disabling the card's regulation and thereby forcing the chip voltage to be read.

However, I'm not quite willing to do what could be irreparable damage if it's not likely to work. So, what do any of the more insightful and knowledgeable members think of this analysis?

[Ruiner]

this site

http://www.hardoverclock.net/index.htm?http://www.hardoverclock.net/html/reviews/pl-ip3t/pl-ip3t_1.htm

shows detailed pics using a pin wrap/cut to get 1.8 vcore on that chip. You could use nailpolish to cover instead of cutting the one pin. They get to 1500Mhz.

It's a nice article, but it is in german. Use babel fish.
The pics and graphs are universal, of course.

[MattR]

Ruiner,

Thanx for the reply and link, but I'm not sure that's the problem. The Vid1-Vid2 wrap will give 1.675 volts, which should be plenty (as I understand it) for a nice stable o/c. The problem w/ this Powerleap adapter seems to be that the wrap/pinhole mod does not work to raise the chip voltage. Something in the circuitry is preventing the chip-defined voltage from being read.

That's why I've speculated that cutting the vid traces, as is done on the dipswitch mod, may force the adapter to read the voltage from the vid pins rather than the adapter's voltage regulation circuit. Seems logical, as the difference between the two techniques would appear to be only that voltage is fixed w/ wire trick and variable w/ switches. But then, my understanding of these matters is quite limited.

Hence the post.

[Blimpyboy]

I agree with mattR. I have performed the wire trick, but have seen no evidence that the powerleap adapter is honouring the modification by upping hte voltage like it should. The German site is nothing but standard pin modding stuff.

If anyone has an unmodified powerleap adapter out there, could you please try the wire trick (easy to do) and tell us if it improves your overclockability? I want to hear that it works for at least one person.

I don't know what cutting the VID traces would do. When you are modding the adapter you need to cut them because now the VID signals are determined by the dipswitch and the wire you solder, rather than the CPU.

[Ruiner]

I think they tried that at the german site. The pin wrap (vss to vid2) got them 1.65 vcore and 1440Mhz. Then they wrapped vss to vid3 and cut vid0, and got 1.8vcore and 1500Mhz. They never did show MBM or bios voltage readings though.

[DSTA]

There's some funny business going on with voltages and that adapter. AFAIK it's undervolting the CPU @ default settings, so who knows what's actually getting to the chip after VID pinning.

Take a look at these two links. I don't speak Japanese so I had to use a translator like world.altavista.com (makes for some funny reading, if nothing else ;) )

http://www.ac.wakwak.com/~takapen/htm05/pl-ip3t-1.htm

http://www.ac.wakwak.com/~takapen/htm05/pl-ip3t-2.htm

Something to do with VID4 and possibly playing with variable voltage of the VRM?

What's most interesting IMO is the table right at the end of the second link. They measure what the thing puts out after the mod, and that certainly looks spot on.

Good luck.

[Real_Crashman]

I've tried standard pin wrapping with both 1.675v and 1.875v and haven't seen any proof it worked. I still get unstable at 110MHz FSB. So maybe you do need to disconnect something for it to work!

Wish I could have a good japanese translation of those. They seem to be the key. Or at least those who have successfully modded their adapter could write an English howto.

It appears that they also made other modifications to it, perhaps to resolve the P2B incompatability?

According to the charts, the 1.875v setting was replaced with the 1.05v setting, which would at least explain something! I had never noticed that before!

The other thing they do is

"Temperature detection of the thermal diode of the on the die is made effective. "

Thats not necessary to achieve higher voltage though.

Ah, I should make that mod!

What does it do?

Also how do I go about removing the powerleap retention mechanism? (the plastic thing around the edges of the adapter)?

[Real_Crashman]

Allows you to take thermal reading directly from the CPU as long as your motherboard supports it, I believe.

How does this compare to taking the reading from Intel's heatSink Fan?

Also I've stared at the powerleap adapter for an hour and can't figure out how to take the plastic off. Please help :)

[Real_Crashman]

The fan only reports RPM, not temp!

I think the problem with the P2B has been identified.

Apparently it's purely a BIOS thing, there's a bug that prevents any CPU with a multiplier of 11 or higher to work (the coppermine celli 1.1 GHz is affected as well).

One of the Powerleap's German resellers has published some more compatibility info (look here (http://cpuupgrade.com/html/tualatinslot1liste.html)). Seems that using a 10x multiplier CPU (Celli 1.0A or underclocked P3 Tualatin) helps quite a few of the previously uncompatible boards.

[Real_Crashman]

That means the PIII Tualatin will work, both the desktop (256k) and server (512k) versions, since
1.13GHz=8.5x
1.26GHz=9.5x
1.40GHz=10.5x

Hi,

I am new to this forums, but have been following it closely for the last month. Hello everyone.
Now, this append is to let you know that I've been struggling with a powerleap pl-ip3 for some days and here are my conclussions :

1-Standard VID pinning does not work (wrapping VID1-VID2 to get 1.675)

2-VID pinning VID2 directly to VSS DOES work. I did the 'wire thingie', dropping a small wire in the socket pin holes. Note that the two pins are not exactly adjacent, but it is no dangerous, since the sorrounding pins (VID0 and VID1) are supposed to be already at Vss, so if you get the wire touching any of those, its OK.

Before VID pinning, I could only get my CELLY 1.0A up to 115FSB. After, I am able to run stable at 124, and ALMOST stable at 133. I will try VID pinning to 1.775 next...

[bearulez]

DSTA, Actually I think the problem is something else with the Asus P2B Series. If Multiplier higher than 11 wouldnt work then how come celeron 766 runs in those boards? Well at least the official Asuspage states that they are working...


Cant be Microcodes either, I checked those and it didnt help
FTC: How about it? did u check in 133?

Hi,

Well, no only I could do 133, but am running now at 140 (1.4G), absolutely stable. What I did is :

Since the vid pin VID1-VID2 did not work and VID2-Vss did work, I assumed it is because VID1 is NOT at Vss level, but open. In this case, I was getting 1.575V instead of the intended 1.675!. So I vid pinned additionally VID0 and VID1 to Vss, to make sure both are at GND and ... voila! I can run 1400 FSB. (note that this can be done very easily just by crossing a wire over the first vid pin (VID2-Vss), so that this new vid pin connecting VID0 and VID1 forms a cross with it.

Note that my machine is an IBM Aptiva 2178 (not very OC friendly), so I have to run CPUFSB to change FSB for other than 100 or 133 (that can be selected directly via PL-iP3/t pins)... and since my PLL next option is 150FSB, I am not yet ready to try this (need better cooling).

Now, the question remains : How can VID0 and VID1 be open in the processor if it is a CEL1.0A at 1.475 ??? My opinion is that these pins are grounded internally through one of the Vss pins
of the processor... and it is one for which the PL-IP3/t designers just forgot to connect... does this make sense ?

One last thing, my chip is a retail Celly (Phillly) 1.0A.

Hi,


Just to give an update to whoever may be interested... after some weeks now, I finally found that my overclocks with this slocket are *not* stable. Moreover, I have also tested with a Celeron tualatin 1.2 and in both cases the same symthoms : whenever the clock is set to something greater than 1.24 Ghz (aprox), the system starts becoming unstable.

The sympthoms are unexpected lockups and hangs, forcing me to reboot the machine. It is also quite frequent that after such a lockup, the machine does not even boot until some time has passed... (1/2 hour or so).

I have also been able to verify that default vcc voltage is set to 1.3v, and vid-pinning works correctly if this is taken into account... unfortunately the higher the voltage, the more frequent the lockups also, so it does not help.

I have already discarded my PSU as source for this problems (swapped my original one, 155W for a new one, 300W and same thing). Also heat is not an issue, due to the relatively 'low' mhz I am working with, for a tualatin. Besides, I've got a good ventilation and HSF, and system behaves the same with/without cover.

So, of all thested things, I have only been able to find the following things that 'help' a bit :

- Reducing the clock (100 mhz is stable, runs prime95, 3dm2k1, fs2k, and many other stability tests, but 105 mhz starts being unstable). Note that my previous processor was a P3800EB, running at 140FSB, so I know my components *are* good for lower speeds.

- Going to CAS3 from CAS2... however, note that before and at 140 mhz I was able to run CAS 2.5, so why with the same memory (it is QPI PC166, so overspeced for this speed) I can not run CAS2 at 105 ?

So, my conclussion is that the PL-IP3/t *works*... barely. I think it is running the processor out-of-spec, and probably the FSB gets very easily corrupted with very little changes... all in all, quite deceiving. Does anyone have an idea on what could be done to reduce bus corruption, or anything I could try to try to meke it more stable?

uhm :) I've ran wo/ any problems (disregarding fan noise;) 1.2@1.604 (133FSB) 1.825V 24h/d for 2 weeks... under 100% load. Win2k and I rebooted cause I installed new software.

I switched to 1.1A to reduce noise. Now it's running @1470, 1.80V. I haven't done thoroughly stability testing, but haven't had problems when 1.80V either. When 1.70V it crashes windows.
I HAD problems w/ 1.1A at start... I thought I'd never get it 133FSB cause I couldn't even post 1st @ any voltage. Then I turned off my psu (not only comp power off, but the psu switch off too) before adjusting the voltage from dipswitch and I think it solved the problem.

I suggest you to bump up the voltage and see if you can get rid of stability issues.

[FTC]

Hi,

Well,... finally I ended up VModing the adapter, and after some suffering, all went well. After I did this modding, the PL-IP3/T is behaving rock solid... I can do 120 FSB (1440Mhz) w/1.475 Volts (default) rock solid, 124 FSB (1488 Mhz) with 1.575 volts (and maybe less..). And this time when I say rock solid, I made sure... several hours running prime95, 3dm2k1, FS2K, .... and several other stability tests. I can boot and sun some stability tests at 1.8v and 133 Mhz (1.6G), but get some occassional exceptions, so probably I'll try again after some weeks (and burnin). Meanwhile, moded also the fan to run 7v, and will relax with a low-noise and quite fast system.

Regards and thanks to everyone in this thread

Hi.

Actually we did update the PL-iP3/T recently, to version 2.0. It does have
voltage jumpers, so it can more easily overclock now. The new manual will
be posted ASAP, sorry for the delay."
