Overclocking an old computer - Page 2

post #11 of 13
dude...100mhz is the base clock..x4 for Intel = 400mhz FSB. If you look in your BIOS it will tell you 100mhz...that is the same thing. If it said 200mhz you would have a 800mhz FSB.

The pin mod is sooo easy. You just pull off a tiny piece of insulation from a very small wire..like 30ga....then use some tweezers to put it on the cpu, pin A6. Next take a paper clip and widen the hole on your mobo socket to accomodate the insulated pin, [dont worry..its just plastic and will not 'loosen' any connection to the cpu] pop your cpu in and tighten the cooler...done! Now your cpu fires at 3.3ghz without any FSB adjustments.

If your interested, I can post a pic of a completed mod, I have several 478 cpu's that are pin mod'd.

How does the pin mod differ from just increasing the FSB?

It will start the cpu and the mobo at the 'new' speed, by default...no adjustment needed. If your cpu re-boots because of an error, it will likely hang and reset CMOS, clearing all of your OC settings...

You wouldnt have to worry about that, as the mobo, would see your cpu as a 3.3ghz/533mhz FSB Intel CPU. You will be able to use faster RAM [266mhz-400mhz] than before, as most mobo's do not support ddr333-400 in a 400mhz FSB [or 100mhz base]. So there are a few benefits to doing it aside from just having a faster cpu..faster RAM..faster mobo. Its the stability of the mobo too. Most older 478chipsets do not clock well when approaching the upper limits of their FSB strap. So it might allow you to clock beyond 533mhz FSB easier..as the mobo is starting from there instead of 400mhz.
