way to easy, can't find my crystal oscillators

so... gigabyte GA-5SMM came in:



66/75/83/90/95/100/105*/112*/124*/133* MHz System Bus
CPU Voltage 1.3V~3.5V
Clock multiplier 1.5/2.0 ...... / 5.5
CHIPSET
SiS 530 & 5595 AGPset
512KB PB SRAM on board

Mine comes without the onboard SRAM though. It's a rev1.3 board. Bummer: no BIOS overclocking options, so far I managed to run WinXP setup More later on.

Should be supported:

Upper Fet becomes super warm even with low power Pentium1, think there was a bad contact between FET and PCB. Anyhow, desoldered it and replaced both CPU vCore fet's with D452 fet's which I found on a dead low-end ATI videocard. Works nice, no heating now although the board refuses to boot when using one specific PSU where it work on flawless before the modification. Strange things these computers.

Interesting side note:
PC Chips M590 uses the ICS 9148BF-17 PLL, the system base clock is being generated at pins 44, 43, 41 and 40 which are called CPUCLK0/4. Deconnecting one of these pins makes the system not bootable, but it seems that there is no real difference between each of these CPUCLK pins because you can deconnect one and put it together with one other. Tested by deconnecting term.resistor at pin 40 and making the connecting between clock trace of pin 40 and clock trace of pin 43.

My next tryout was to completely deconnect the CPUCLK pins by removing all the term.resistors and use an external CPU clock. I used an Intel Slot A board with ICS9250BF-81 clock oscillator and linked the CPUCLK pins to the PCCHIPS board where I removed the term.resistors. This however did not work out and now the PCCHIPS board doesn't boot anymore, even with everything back at default. Another victim of war
