Sharky Extreme's Vince Freeman heeft een flink artikel gemaakt over het overklokken van Celeron FCPGA processoren. Hij heeft hiervoor 3 processoren gebruikt, te weten de 566Mhz, 600Mhz en 700Mhz versie. Het is een zeer uitgebreid artikel van 23 pagina's waarin ook een stukje geschiedenis van de celeron wordt beschreven. Je kunt het hier vinden.
While it's difficult to draw firm conclusions with just this small amount of overclocking data, there are a few constants that were easy to see throughout the testing. First, all the tested processors would easily reach 850-875 MHz speeds (if available) at extremely low (1.5V-1.6V) core voltages. The overclocked processors ran perfectly, exhibited no problems at all, and CPU core heat stayed within limits that were manageable using a retail heatsink and fan. Moving higher than 850-875 MHz brought a whole new set of problems and required extreme (1.8-1.85V) increases to core voltage, which resulted in increased core heat (44-46 degrees C), and required upgrades to the CPU cooler.
From this data, the Celeron 566 would seem to be the overclocking chip of choice, given that at the 100 MHz FSB, it hits a very manageable 850 MHz core speed. If you can find it, the Celeron 533A is also an excellent bet, and online polls have it as a virtual lock at 800 MHz. Moving higher than that gets more risky, as our difficulty achieving 900 MHz with the C600 can attest. The 633-700 MHz models have increasingly higher multipliers and aren't especially suited for 100 MHz FSB overclocking.![]()
Conclusion:
The new FC-PGA Celerons have all the potential of being the next big thing in CPU overclocking. They share a similar core to the higher speed Pentium III processors and when overclocked, offer an extremely good price-performance ratio. Of these chips, the low multipliers of the Celeron 533A and 566 make them the ones to look for, and the 600 MHz and above models should be reserved for only the most risk-tolerant of overclockers. The only possible fly in the ointment is the extremely low price of the Pentium III line, which might be a bit too attractive for some buyers. Still, the prospect of an 850 MHz processor for under $100 is certainly enticing in its own very distinct way.
Wederom een leuk stukje leesvoer waar de bezitters van een Celeron of de mensen die er eentje aan willen schaffen best wat aan kunnen hebben.
dEjAvU was met dit stukje nieuws het eerst. Ook hij heeft de nieuwssubmit gebruikt.
