Overclocking a PII 266....

by Jay » Tue, 17 Nov 1998 04:00:00

Can anyone help me or point me in  the right direction on info on
overclocking a PII 266 (Intel, with a LX 440 Micronics motherboard)

How fast can I take it to, without having bugs or problems, and.....

If I up it to say 300 or 350 MHz, will it make a significant difference in
GPL ???

Thank you
Jay J

It depends on your board, your memory, your karma, the sun, the moon,
the alighment of all the above, and most importantly, how lucky you
are...

Remember, you are doing something that the manufacturer did not engineer
into the motherboard/processor, and you may, or may not, get away with
it.

Yes, many are sucessfull with this.  However, you usually don't hear of
the disasters because of the embarrasment involved...  I have replaced
many a motherboard/processor destroyed by clock-chipping.

Just keep one thing in mind.  It may work, or you may damage your
computer.

Overclocking a PII 266 to 300 should not be a problem just by changing the
jumper / bios setting for the clock multiplier from 3.5 to 4.5 (3.5 x 66 MHz
bus = 266, 4.5 x 66 = 300).  Note that Intel changed the later PII 233/266
such that they could not be overclocked this way.   Since the 233/266/300
PIIs all share the same .35 micron spacing between transistors, cooling
should not be an issue.

I did just this to my Dell (Intel 440 FX board) and I got about a 10%
increase in GPL framerate - for a full field start with all detail, only
cars in mirrors, and about 1/4 detail bias, at Nurburgring, my frame rate
went from 15 to 18 just before start, with the minimum going from 11 to 14
fps.

BTW, prior to this, I got a bigger performance gain going to a PCI sound
card (Diamond Monster M80 - poor sound, but helped framerate).

3.5*66= 233, a 266 has a 4x multiplyer.
