| I have been overclocking since I bought my first Celeron 300 (a
66mhz chip
| with a multiplier of 4.5) costing $118.00. At that time the main
Pentium
| was the P2 450 (a 100mhz chip with a multiplier of 4.5) which cost
$689.00.
| That's a $576 difference. Tests at that time showed a performance
| difference between the Celeron 300, clocked to 100mhz FSB, and the
P2 450,
| clocked at 100mhz FSB, to be 0.01%. I was able to have a cpu that
was the
| equal of the top Pentium for a fraction of the cost. The same
reason,
| limited funds, sparked my last upgrade, which was a P4 1.8 ($148)
which is
| running along very happily at 2.6ghz ($389). I have been lucky in
that all
| of my overclocking has been able to be done at stock voltages. But
part of
| that is also doing my research into the compatibility of the various
parts.
| Before even thinking about placing my order I had discovered (thru
usenet
| and forums) which mobo/cpu/mem combination would give me the most
for the
| least, including longevity. Now there are some out there who o/c
just
| because they like to tinker. And there are those who just have to
get the
| last little micron of speed. But I think you will find that the
majority
| are people who are on a budget and need to have the processor and
graphics
| power, e.g. flight sims
, that they wouldn't be able to afford
otherwise.

Well said, and economically insightful to anyone that does not
understand. I also take this approach when the "word" on the net is
out that some new CPU readily overclocks much higher than it's rating.
I've been overclocking CPUs since my first AMD133 turned out to run at
166 w/o a burp. Right now, I have 2 AMD systems OC'd, one from 1600
to 2100 and the other from 1600 to 2000 MHz. Both are $43 CPUs, Duron
1600s, one with the full L2 cache mod to make it, essentially, an
XP2800 (which costs well over $100). Sadly, the second Duron 1600
that I purchased is "superlocked" and there is no control of the
multiplier, nor can the entire cache be enabled, so the only
overclock available is via FSB.
Only after an overnight run of memtest86 and some serious time running
prime95 will I feel comfortable that an OC setup is reliable. If the
tests show the machine is reliable, and operating in a temp range that
is considered normal, then why not take advantage of the extra speed
that just might be available?
Overclocking a CPU is not the same as driving more voltage into an AMP
circuit. An AMP circuit is designed to work within a specific power
output capability, and raising the voltage on the power rails would
wreak havoc with an amplifier circuit, yet on the flip side, most CPUs
are designed to run faster than their ratings.
