Asus P5K "Vanilla" vmods

[Learn]

Hmm, will change my mod then too!

Is there any Vfsb mod out there and anyone knows what exactly does Vfsb do?

With my E6400 and E6600 it doesn't help, but the GTLREF seems important with the quad core.

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.

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

I can take a look the next week.
