First time overclocker.

I am currently the proud first-time-overclocker of a 2600+ TBred (upped the
FSB from 166 to 179, now running at 2.24GHz (and benchmarking faster than a
3200+, thankyouverymuch!). I'd love to OC some more, but I have some serious
limitations- my mobo, an Asrock K7S8x Rev 3.0 doesn't appear to allow
changing the multiplier or core voltage (unless i'm mistaken?) and any step
over 179FSB resorts in the BIOS resetting to a much lower FSB (estimates CPU
as a 2000+)- a major step over 179MHz resorts in the computer failing ot
start up. My CPU is currently running at a rather frosty 27 degrees
Centigrade, so there should be plenty of room to play, but I assume the mobo
is holding me back (hell, it only cost £25 UK). My CPU was purchased around
October/November last year- is it likely to be multiplier-locked? And what
is likely to be causing the 179FSB limit?

Two things come to mind....there's no way a Tbred 2600 overclocked to
2.24Ghz is actually running at 27C....5 or 6 degrees above ambient room
temp! Something is being misread. Try using AIDA32 or Sandra 2004 and see
what they say temp actually is. If they both say CPU diode is 27C, then your
diode is way out of wack. I suspect your temps are much, much higher than
you think and could be causing instability. The second thing is your
DDR....is it PC2700 or PC3200? Lots of PC2700 becomes flaky when pushed much
past 166FSB. Some will take it, some won't.
