I just received my new Celeron 500 yesterday from Multiwave Direct. I proceeded to overclock it and it is now running rock stable at 564MHz. The CPU benchmarks at 25% faster than my Celeron 400 o/c at 450. I am well pleased so far.
Here are my system specs.
Abit Bx2 v 2.0. Flashed with newest Bios to handle up to 550 PIII
Corsair memory 256 CAS 2
Diamond Viper 770 Ultra
Soft Menu settings:
CPU Operating Speed User Defined
Ext Clock 75MHz (1/2)
Multiplier x7.5
SEL100/66# Low
AGPCLK/CPUCLK 2/3
L2 Cache Default
Speed Error Hold Disabled
Core Voltage 2.0v
CPU temp 33C
This baby really flys !!!!!!!

I thought all the 400+ Celerons were multiplier locked.
What I have:
C400 o/c to 450 (6.0x7.5) PCI @ 37.5Mhz
Normal CPU fan in a 5 x 5 1/4" bay tower (big)
6.4, 3.2 Quantums, 6.4 Seagate (IDEs
2 Cheapo NICs (ISA and PCI)
ATI Xpert98 8meg AGP
SB Live PCI

I bought it in the winter so I guess the older 400s don't /c as well as the new ones?

The multiplier is locked at 7.5 on the 500MHz Celeron. 66 bus speed X 7.5 = 495MHz. I guess they round up. I increased the fbs to 75 MHz. 75 X 7.5 = 562.5. My HardInfo utility says it is running at 564.4MHz.
