Intel Pentium 4 2.4B GHz Processor Review
Not everyone can afford top of
the line processors like the Intel Pentium 4 2.8 GHz, but processors like
the P4 2.4B are now clearly one of the best "value" Pentium 4's out
Offering a good mix of price and performance, we'll
be taking a look at whether this processor is "the one" to get.With a street price of around $330 CDN ($184 US) the P4
2.4B is not inexpensive, but when you compare that to the price of higher end
P4's, $330 is actually quite a bargain .
The P4 2.4B runs with a 533 MHz FSB
(hence the 2.4B
) which gives the processor up to 4.2 GB/s worth of bandwidth.
This is an increase from 1 GB/s of the older 400 MHz FSB Pentium 4
The 2.4B features 55 million transistors which are etched
on an enhanced, shrunken 0.13 micron Northwood Core. The unit we are testing is
of the B0 stepping, runs with a default voltage of 1.5V and has a S-Spec of
In terms of
technology, the Pentium4 2.4B has all the technical goodies we have come to expect; including SSE2,
Netburst architecture and Advanced Transfer Cache. If you'd like to learn more

Overclocking the 2.4B
the 2.4 GHz Pentium 4 is based on an earlier B0 stepping, we
weren't too sure how well it would overclock. I began to up the FSB slowly and at
the 150 MHz FSB mark it started to show some stability problems. Increasing the voltage to 1.6V stabilized
things. After increasing the FSB to 160 MHz, the processor again started to
show some stability problems and we had to set Vcore to 1.65V.
what voltage we gave the processor, the chip just wouldn't go any higher
than 163 MHz FSB. We used an Antec 300W PSU in this review so it's possible that the limiting
factor may be the powersupply. In the end we settled for a 163 MHz FSB, which
gave us 2.93 GHz overclock. Not bad for a "budget chip."
