We can't answer that question with authority as:

a) There is no one single "correct" answer. Once you get beyond a certain
point you will start to constrain the operational life of the CPU. However,
all processors differ slightly, and none of us can tell you exactly where
the onset of this situation is.

b) The amount of voltage you can run is related to the cooling solution,
case temperatures and so-on. The cooler you run it the more voltage you can
safely run.

As a general rule, +10 to 15% is sensible for these CPU's. If your cooling
is good you could go a little higher - 1.85 maybe, but at all times you
should be monitoring temperatures and testing for stability.

Now, all that said, what makes you think you need to ramp the core voltage?
If your system has been stable at whatever it was running for some time, but
is now beginning to suffer from creeping stability, the chances are that the
problem is elsewhere, and thus increasing the core voltage won't help.

I'd suggest a number of potential causes - including failing capacitors on
the motherboard or PSU, OS corruption, degraded thermal solution (dying
fans, dust etc.) as more likely causal factors than problems with the
processor itself.

Default for that Celeron is 1.5v. But, That is basically the same processor
as the Celeron 900. The Celeron 900 is a 1.7v chip with 100 FSB. That being
said, you should be ok at 1.7 or even 1.75 and FSB at 100 mhz.

I ran several Celeron 600 @ 900 machines for years. One of them was even
able to creep up to very near 1 Ghz.

Hey dj, I have a 600 celery and have been OC it for years at 900
using 1.9 volts with no problems. I have a bh6 1.01 mb...
I'm using a Thermaltake Golden Orb fan , bought it in sept 2000.
Plus using Thermal grease ....
I think it's almost time to upgrade ! lol......
but the system is still stable and causes no problems.
Take the voltage up in small increments until the cpu is stable.
You might just need to put some fresh thermal grease back on,
it tends to dry up over the years...
good luck
joe
