Mesure the v-mch and fsbvtt with the lower setting in the bios.
I don't need the v-mch mod, never done (no need) i can't confirm anything.

Hmm, will change my mod then too! :)
Is there any Vfsb mod out there and anyone knows what exactly does Vfsb do?
the max v-core i can give on my p5k is 1.92v more and it shut down, any ovp mod or somthing? have you guys tested max v-core you can give on windows?
thanks :) :toast:
With my E6400 and E6600 it doesn't help, but the GTLREF seems important with the quad core.
Interesting Article about: Adjusting A/GTL+ Levels for Increased FSB Signaling Margins and Overclocking
Some tests done today:
Config:
P5K (v-core, v-droop, v-ddr2, v-cpupll/southbridge/sata)
Revision 1.02G
BIOS 0603
E6600 388 x 9 1:1
v-ddr2: 2.2v
v-core: 1.38v
FSB VTT in the BIOS | DMM | GTLREF
AUTO | 1.55v | 0.99v
1.20v | 1.55v | 0.99v
1.30v | 1.33v | 0.85v
1.40v | 1.44v | 0.92v
1.50v | 1.55v | 0.99v
v-MCH in the bios | DMM | Heatpipe Temp*
AUTO | 1.58v |
1.25v | 1.58v | 50.8°C (+/- 0.4°C)
1.40v | 1.43v | 44.3°C (+/- 0.4°C)
1.55v | 1.58v | 50.9°C (+/- 0.4°C)
1.70v | 1.73v | 56.9°C (+/- 0.4°C)
Now with the v-mod (FSBVTT & GTLREF), VR set at 14K Omhs
FSB VTT in the BIOS | DMM | GTLREF
AUTO | n/a | n/a
1.20v | 1.65v | 1.06v
1.30v | 1.43v | 0.91v
1.40v | 1.54v | 0.98v
1.50v | 1.65v | 1.06v
FSB VTT set at 1.20v in the BIOS and V-MCH set at 1.25v in the bios = odd

read points GTLREF
read points FSB VTT post #51
* Digital thermometer + good probe in the heatpipe (top of P35 in the heatpipe),Noiseblocker SE2 @ 7v for the 4X512MB and
heatpipe. Temp after 15 minutes of Prime95 25.3 FFT 1024.
I can take a look the next week.
awsome, thanks :)
well ovp must be pin11 to ground :

thanks to jonny bravo, http://www.ocxtreme.org/forumenus/showthread.php?t=1153
well.. it's being hard to find a spot to solder... i'v insulated my p5k with nail varnish :S it hard to check with multimeter lol
Pencil mod vdrop P5K SE?
it must be. my board are stupidy insulated with nail varnish it's being hard to make some reads...
1: can you please read resistênce between pin 11 and ground?
2: can you find a spot that have 0 ohm resistênce to pin 11?
it must be connect an pot with res= (1) between that spot (2)and ground
or find the smd resist. that make the resistênce you read on (1) and pencil it
i think, maybe wrong
:toast:
Strange the vdroop isn't working for me :shrug:
Pencil mod that is....
Btw are the mods at teh first post all correct and working? wil try them tommorow :D
vDroop pencil working fine here.
This one works. link
Config:
P5K
Revision 1.02G
BIOS 0603
vcore: 1.7bios
vdroop: pencil
E6600: vid mod, 1.40625v.
I removed the 681 Ohms resistor for testing the vmod.
http://www.overclocking-jp.eu/public/vmods/100_6915.jpg
With 165 Ohms: (and with the vdroop)
http://www.overclocking-jp.eu/public/vmods/2.000.jpg
After 2.040v in the BIOS, 2.07/2.08v (DMM)
http://www.overclocking-jp.eu/public/vmods/2.040.jpg
After 2.040v, no monitoring (maybe 2.1v DMM)
http://www.overclocking-jp.eu/public/vmods/0.000.jpg
In parallel you need something like 217 Ohms for 2v in the bios (with the vdroop) so, 5k or 2k or 1k Ohms can do the job. PWM get really hot (my insulation on the back of the PWM melted! :ROTF: , CPU under 2 stages cascade, beware.
So are you saying that you can solder say a 1Kohm variable resistor in parallel with the 681ohm resistor in the pic and this will "fool" the DAC ?
thanks for info :) i'v cheked the 681ohm resistor has 20 ohm to ground from 1 side and 700 to ground on the other side, must be just solder 1k or so to ground on 700ohm side
or solder in paralel on that resistor.
i'm a litle confuzed, it will be needed vid mod on cpu? you just talk on this mod and vdroop mod, why no v-core mod? you substitute vcore mod by vid mod on cpu?
realy thanks :)
:toast:
It seems to be working just fine. (i can't say more, there is nothing on the "typical application circuit" in the datasheet for that pin. :shrug:
Solder a wire on each red points to your VR (set at 1000 Ohms) then decrease the resistance.
No need VID mod.
For the vdroop it is much better with, but it's not needed.
Do not use the other vcore mod, only that mod (without OVP).
That vcore mod only work when you set over 1.6000v in the bios.
(when i hit 2.10v (DMM) the monitoring say 0.024v)
PS: and thx to the dude of the pic (link on my previous post)
Again, lot of vcore = dangerous, beware.
Voila :D
i'll tryit soon :D
have you tryed to enter windows @ more than 1.92v ? i can get more than 1.92v on bios but not on windows, the max i try was 1.96v on bios ok but when it enters windows, restart.
:toast:
I tryed 2.02v, it was OK.
cool, so it's an alternative v-core mod. i'll tryit very soon, thanks can you point-me to what fets and chips overheat?
thanks :)
for me worked good too :)
