The Intel Celeron Coppermine
533A & GlobalWin FKP-32
begin to describe the feeling that this particular processor chip gave me
a few seconds after installing it into the motherboard and booting up for
the first time. You see, it wasn't supposed to work. But I'm here to tell,
no SHOUT, that the Celeron 2 series of processors work naked (sans any adapters)
in the venerable Abit BM6 and probably the ZM6 boards. And what a pleasant
surprise! Without much effort or expense, the diminutive (pricewise) 533A
provided by Azzo, achieved a too good to be believed 300+ MHz overclock and
has become the best overclocking value to date.

I was sweating
bullets when the 533A arrived via FedEx a few days ago. Although reading various
BBS and newsgroup posts provides some measure of believability, 100% assurance
was not bouncing around in my head. Risk involves some heartache and
loss, but this time, neither reared their ugly heads.
the 1999 Combo
Of The Year one last time, I pulled the 366@550 out and blew off the dust
that the more than capable GlobalWin CPM-32 spread liberally everywhere. Just
prior to removing the chip, I clocked the FSB down to 66Mhz and 1.9 volts.
Rumors have been that if the BIOS of your MB doesn't support the newer 0.18u
Coppermine chips (P3 or C2), disappointment and stomach turning can happen
when booting to a significantly higher voltage than factory specs allow. This
C2 has a default voltage of 1.50, while some speed equivalent FC-PGA P3's
are labeled as 1.60 volts. If the BM6's PQ BIOS didn't "get" the
C2's core voltage right, I might have heard that dreaded "popping"
sound followed by my own gut wrenching hurling sound.
the spec sheet from Intel that had the C2 533-600 particulars and glanced
at all the numbers I could. The max (before damage) static voltage for the
533-600 C2 series is a high 2.1 volts. The maximum recommended operating voltage
was harder to determine as a listing with that type of wording was not found.
What I did spy was a Vtt and Vcc spec which ranged from 1.545 to 1.635 volts.
I'd venture to guess that 1.60 volts would be the maximum I'd run at long
term and Abit's PQ BIOS only allowed a maximum of 1.70 volts. Please
don't subject the little marvel to 2.0 volts, boot up at 1+ GHz, and write
to tell me as you suddenly smell something akin to burning silicon.
white BIOS screen faded in for the first time, I laughed and cried. The laugh
was the "HA" kind that only happens when you've done something that
many say can't be done. The crying was the good kind too, because the PQ BIOS
has hidden in it nearly full support for the C2 chips. I saw 1.50 volts and
the default highlighted after entering the BIOS that claimed the 533A
was a 533E. Since the ZM6 is a video castrated version of the BM6,
I could easily believe that similar results would be obtained although I have
no ZM6 available for evaluation.
By this time,
I did the "happy dance" and ran around the room hollering "YES,
YES" for about 2 minutes. That was just for a lousy DOS boot at 533 MHz.
Now, I love overclocking and have even squeezed a P120 up to 133, but I wasn't
fully prepared for the overclocking nirvana that the C2 so graciously provided.
