Sharky Extreme heeft een megalange review van de nieuwe Celeron 'II' 600 online gemikt. De benchmarks laten weer hetzelfde beeld zien als eerdere reviews: de Celeron is geen snelheidswonder, maar overklokken doet-ie wel goed. De Celeron 600 van Sharky Extreme deed niet moeilijk over een kloksnelheid van 816MHz:
Booting for the first time at 90 MHz resulted in a totally blank screen and I promptly rebooted. After resetting to the default speed, I increased the core voltage to 1.65V. At the higher voltage, the PC booted up, but it would not progress into Win 98. Raising the Celeron 600's core voltage up to 1.70V alleviated this issue but I still found some anomalies during overclock testing. Taking the CPU to 1.75V solved all of the issues and I ran the processor at 816 MHz for hours without any problems cropping up. This drastic increase in both core voltage and speed did come at a cost, as the CPU temperature increased to approximately 43 degrees Celsius. This is still well within normal operating conditions, but care should be taken to acquire adequate cooling if you're going to attempt this.
Unfortunately this was as far as the Celeron 600 would go, and attempts at the 95 MHz FSB (856 MHz core) met with serious problems. It would easily boot at this speed and even go into Windows, but any attempt at long-term testing resulted in a hard lock. Further attempts at core voltage increases, even up to 1.85V, didn't solve the problems and the Celeron 600 continued to lock at the 856 MHz core speed. The Global Win CPM25603-32 is certainly a capable cooler, but to achieve these kinds of overclock speeds with this chip, I would definitely require a Peltier or other high-end unit.
