Je hebt een goedkope Celeron II op de kop getikt en je wilt hem eens flink gaan overclocken aka tweaken, en wat blijkt: de 100MHz FSB is geen haalbaar doel tenzij je het voltage wat omhoog krikt, iets veel moederborden niet genoeg willen doen. Na eerst je moederbord flink uitgescholden te hebben kan je deze guide van HardOCP gaan lezen, daar wordt namelijk uitgelegt hoe je, je voltage wat kan opvoeren :
Now here's the beauty of the whole thing - connect VID1 and VID0 (in addition to the already internally connected VID2) to Vss to make the CPU boot at 1.65 volts! This doesn't change the 10% adjustment factor in the bios, but now it STARTS at 1.65 instead of 1.5 volts! At 10% maximum tweak, the CPU now feasts on 1.8 volts of overclocking goodness whereas before the maximum was 1.65 volts...what used to be the max is now the default.
To accomplish this, I thought about soldering jumper wires across the back of the socket370. Not only would this make the change semi-permanent but also it would void the warranty. To solve this problem, I pulled one strand out of an 18 gauge multistranded wire and, using just a couple of turns on each pin, wire wrapped VID0, VID1, and Vss together on the cpu itself (see picture below) being extremely careful not to contact any of the other pins. The benefits of this option are:
1. Only the CPU is changed.
2. The CPU retains the new preset voltage regardless of motherboard used.
3. The motherboard warranty remains intact and I can swap out the CPU with a PIII without having to remember I had modified the motherboard.
4. It is reversible in about three seconds.
The end result is that my 7VCA will now run my Celeron II at 800 MHz (haven't tried higher yet...still having fun with it the way it is) rock solid stable!
