What for an info are you searching for ? :confused:

It's no problem at all to modify your board ;)

For the KA7500B IC, I could not find any info on the web (I use www.icmaster.com). IC Master said that it is SAMSUNG (PWM Controller, Voltage Mode, Complementary Output).
But I could not find any info at SAMSUNG website.
I will let you know the result.

Hiya,
the KA7500B is your voltage regulator ;)

You just have to connect Pin 1 with an 12k resistor to Pin 7 to get an increasement of about +0,25 Volt :smoke:

hmm sure?

The KAxxxx IC is the voltage regulator but not for VCORE as per its datasheet (there is no VIDx pins at all).

ooh, i´ve read some articles about it..

it looks bad ..

but u said that the KA34063A is the voltage regulator .. .. have u searched on the web for some detail description ( no idea of the spelling now )
??

I look all over the m/b and could not find the vcore volt regulating IC. The IC I found are: ALC100P (Realtek Audio Codec), KA34063A (voltage regulator), 93705CG(DDR clock), 9248AF-171(Clock generator), KA7500B, LM358(Ampliflier), ST75185C(Serial interface), L31035, 74HCT14D(CMOS), SRS2525L, F 74F08).
Currently, I use CPU COOL to set the FSB(107 MHz). I need higher VCORE to get higher FSB. Please help
