It's not very clear to me either, this German article.
Despite that I understand German well enough. But how I
read it, is that the max voltage that you can get with this
board is 2.1 Volt and that you can get that by using a
50 kOhms turning potentiometer, not a 50 Ohms
resistance. Oh, and mind the k before Ohm: we're not
talking about Ohms here, we're talking about 50 kOhms
= 50 kiloOhms.
I personally doubt that there isn't another maybe more
sophisticated way of modding the board to get even
higher voltage on this board. Maybe you can find one
somewhere by doing a search on Google, or by asking for
help at a person that already has experience with
overclocking a P4T-E.
By the way, I don't know your skills and knowledge, but
are you aware of the fact that 2.1 Volt already is a pretty
high value? And that you need to use more intensive
cooling then the standard heatsink and cooling fan?
Cooling methods like using a big heatpipe heatsink with a
large fan or maybe even water and/or peltier cooling?
Now about your question if you should desolder the "old
resistor", the SMD resistor. It's being mentioned expressly
in the article, that you should NOT remove the original
SMD resistance but leave it between the solder tacks of
the 50 kOhms turning potentiometer. So you have to
solder it OVER the SMD and NOT replace it.
Ok, here I go... The translation of the German instructions,
also for the other people that read this and are interested:
---------------------------------------------------------------
"Vcore mod. Asus P4T-E - Teil 1"
=
Vcore mod. Asus P4T-E - Part 1
(first picture)
"Auch das Asus P4T-E lässt sich seitens der Vcore noch
tunen, allerdings ist hier nur eine Steigerung auf bis
max. 2,1 Volt möglich. Dies halte ich aber auch für einen
guten Wert, weil man die Spannung nicht höher setzen
sollte. Dennoch ist auch hier eine gute Kühlung zwingend
erforderlich bzw. bei Pentium 4 Systemen wäre eine
Wasserkühlung schon zu empfehlen.
Die Modifikation
geschieht auf eigene Verantwortung und auch die
Garantie erlischt mit dieser !!"
=
Also the Asus P4T-E still lets itsself being tuned through
the Vcore, however only an increasment up untill max. 2.1
Volt is possible. This I also regard as a good value though,
because one shouldn't set the tension higher.
Nevertheless also in this case, good cooling is compellingly
necessary. For example already with Pentium 4 systems,
watercooling was advisable.
The modification happens on
your own responsibility and also the warranty expires with
this mod!!
"Die Modifikation"
=
The Modification
"Erst mal sollte man genau die genauen Lötpunkte
eingrenzen, wo der Widerstand einzulöten ist und
sich diese genau einprägen."
=
At first one should accurately check where exactly the
solder tacks are, where the resistor is soldered and
remember this spot.
(second picture)
text underneath second picture:
"Hier muss der Widerstand eingelötet werden
- 50 kOhm Dreh-Poti eingelötet !!"
=
Here is where the resistor should be soldered onto
- 50 kOhm turning potentiometer soldered!!
"Hier müssen die Verbindungspunkte genau stimmen,
weil eine falsche Modifikation das Board zerstören kann.
Der zwischen den Lötpunkten platzierte SMD Widerstand
sollte nicht entfernt werden !!!
Das benötigt ihr :
1. Niedervoltlötkolben ( 6Volt mit feiner Spitze ) mit Netzteil
2. Lötzinn und Fett
3. 50 kOhm Dreh-Poti
4. Lupe
5. gute Beleuchtung
So sollte es dann nach der Modifikation aussehen : "
=
The connection points have to be done exactly, because a
wrong mod can distroy the board. The SMD resistor that's
been placed between the solder tacks should not be
removed!!!
This is what you need:
1. soldering iron ( 6Volt with thin point )
with power supply
2. solder tin and fat
3. 50 kOhm turning potentiometer
4. magnifying glass (if you need it, I don't)
5. good lighting
After the mod, it should look like this:
(third picture)
text underneath third picture:
"So sollte es nach der Modifikation aussehen"
=
After the mod, it should look like this
(fourth picture)
text underneath fourth picture:
"Diese tatsächlich anliegende Vcore ist anschließend im
Hardware-Monitor ablesbar."
=
This actually fitting Vcore is then readable in the
Hardware-Monitor.
"Dank der Modifikation sind jetzt gut 2,1 Volt erreichbar,
wobei hier vorallem das Netzteil eine wichtige Rolle spielt.
Ihr solltet aber bedenken, dass ihr um die maximale
Vcore zu erzielen, auch eure CPU modifizieren müsst,
sofern ihr bereits einen Northwood einsetzt. Mehr dazu
auf der fogenden Seite !"
=
Thanks to the modification, now at least 2.1 Volt is
reachable, at which the power supply here plays an
important role. You should consider though, that to obtain
the maximum Vcore you should also modify the CPU, if
you already use a Northwood.

This was just the translation of the first part of the
German voltmod instructions. I will translate the second
part too soon, but not right now because I don't have
more time at the moment.
