p166 voltaje

[AleU2]

I'm trying to make a P166 work a little faster. I tried setting the bus speed to 75 MHz (187MHz), but the system hanged while detecting drives because of the motherboard I think (it's a bad PcChips M537 3.1).
So I dropped the bus back to 66 and set the multiplier to 3X, instead of 2.5X (198MHz) but, as before, the system hangs while it is detecting drives or memory installed. Sometimes goes beyond and reaches the W95 logo screen... but then...stops.

I installed a MII cooler and heat sink and removed the case, so heat is not the problem.

I will increase the voltage to see if it works and here's my problem, because I don't know the REAL voltage required. Now it's set at 2.9, the next step allowed by the motherboard is 3.5 and www.tomshardware.com says that it needs 3.3v... what is the REAL voltaje with the normal speed?? will it work fine with 3.5V at 198mhz??

3.5v thats your problem minimum 3.3 one of my old MOBO actually uses 3.52 Good luck

3.5v is too high, I wouldn't go over 3.3v and thats with excellent air cooling too...

Possible good news for you. Most if not all 166 chips are not multiplier locked. So look in the motherboard book and set it like a 200 Pentium. That worked for me back a couple of years ago!
