Celeron 4xx / Conroe-L (ES) preview

The thing is that by raising the Vcore to 1.6V we only managed to increase the FSB frequency of our Conroe-L based processor up to 300MHz.
Further investigation revealed that this is a true maximum for this CPU, which has nothing to do with the so-called ?FSB wall? as well as with the mainboard features.

All in all, the overclocked Conroe-L loses to the dual-core Core 2 Duo E4300 showing better results only in those tasks that are not so well-optimized for multi-threaded environments and do not require large L2 cache memory. However, overclocking allows Conroe-L to perform as well as Pentium D 925.

TDP = 35W

The Celeron 4XX engineering sample based on Conroe-L we got at our disposal didn?t have any marking on it and featured an unlocked clock frequency multiplier ... As you can see from the screenshot, our sample allows setting the clock multiplier at up to 12x, which allows us to have this CPU work at up to 2.4GHz frequency taking into account 800MHz bus. Looks like this sample has some hidden reserve for the ?future needs? ... Budget CPUs will lose Virtualization Technology and most likely Enhanced Intel SpeedStep support.
