Hotwiring the CPU – fIXjACK
I recently had my S370 board up and die on me – a cheap 60 dollar Vega board – so I had to find a cheap replacement. A local dealer and buddy of mine happened to have an Intel VC820.
I thought “Hmmm – RDRAM -“YUMMY.” So I got it and an old PIII 600 Katmai. I run a lot of software on this system, such as Sygate NAT and Seti@home. I run this Rambus rig 24/7 under 100% CPU Load, So 600 MHz wasn’t enough and it was starting to frustrate me. And Since I couldn’t locate a PIII 1 GHz to replace the 600, I figured TIME TO OVERCLOCK!
As many of you already know, Intel boards are notorious for their ability not to be overclocked, but that won’t stop us hardcore overclockers, now will it? It’s time to start overclocking using EXTREME methods.
Since the board won’t let us change the voltage or FSB, we’re going to have to use other methods. Ah ha! Soft FSB you say? Nope, the clock generator on this motherboard is a special RDRAM Version of an ICS PLL IC, and it is locked. That takes SoftFSB out of the picture.
This board supports both 100 and 133 FSB but not 66, and If you have 133 FSB
PIII, you won’t be going anywhere. The only way to overclock on this board is to increase the FSB from 100 to 133 MHz. But if you have a 100 MHz FSB chip and you’re reading this article because you’re a hardcore Overclocking lunatic like the rest of us, then the Vc820 has met its match at Overclockers.com.
So there’s only one method left to change the FSB and Voltage on a Slot 1 PIII – cover the contact pins or cut them. I recommend covering, testing, then cutting if all’s well.
