ASUS K8N Vcore mod
hi again :D
i`m back with fresh mod for ASUS K8N, it was done as "remote control" :p: coz one of my friends (OCMaster) start FC and still wants more and more...
he can`t find reday solution on web so decide to ask me ...and here it is:
On this asus mobo Vcore section has 3 phases, master divider is ADP 3166 [pdf] produced by Analog Devices, his slaves are 3 smal chips ADP 3418 [pdf] (one for phase) also by Analog
The 3166 can take 4phase system so... ;)

As you can see mod depend on solder between pin 8 of ADP 3166 and GND wires with conected VR (best is 50k), (pin 8 -> FB is used for sensing and controlling the output voltage) Raising from max (50k) to min resistance geting higher Vcore voltage. For max VR value vcore should be boosted around ~0.06V
Maybe the OCP mod will be needed, now everything works fine :banana:
I can post only teory pic, OCM borow his dig to grandparents :p
here can see chips and read point:

enjoy :D

Hello, the component adp3166 has a security has part of 2V. I have
reussy has to increase the vcore has 1.95V with this same chart.
With a resistances of 25kohm

you cen`t get more than 1.95V correct?
propably the OCP mod is needed, i`ll try to find way for pass this ...but maybe tommorow.
btw, i find now Persivore who have done this first while ago here :toast:
-
sorry but I am French and I does not include/understand perfectly
what you said. My vcore is well has 1.95V by connecting pin 8 has the
ground with a vr of 25kohm. The maximum of the component is 2V.
After it y' has cut the motherboard. would find You here the necessary
one : Vdimm, Vchip, Vldt, and Vcore
3400+ @2840mhz with 1.87V

spox, im polish so... also have problems ;)
OCP -> OverCurrentProtection
nice theard :] I will try to find solution for this problem
-
2V should not be exceeded. Is this that which you wanted?
-
yes "should" ;) that`s only teory.
I can tray do it, but not test it, can work only remote for other users with this mobo
-
Thanks guys :)
That's what I need
I finaly found one :woot: :woot:
-
hello
has you make all the MOD?
-
Not yet, I need de pots now and then it would be fine :)
But one question: is de "Read point on missing + cap" the point where I can test the voltage?
