ASUS P5AD2-E Premium 925XE w/ 3.46EE & 3.8Ghz

The motherboard we are going to look at today, the P5AD2-E Premium probably is one of the most features packed motherboard around (Dual Gigabit LAN, Wireless G, 8 SATA channels with RAID etc.) and we will test out new Prescott 3.8Ghz E0 against the 1066Mhz FSB 3.46 Extreme Edition.


Intel has been driving the market to adopt PCI Express since
late June when they first introduced the LGA755 Prescott with a slew of new
chipsets; the 915 series and 925X. The Intel 915P/G chipsets are naturally well
accepted in the corporate environments as well as mainstream users. However, the
925X which is meant specially for the enthusiast market, ironically has not been
well received by the enthusiasts. There are a number of factors contributing to
this drawback. One important factor is the limitation on overclocking where a
number of motherboard manufacturers failed to overcome FSB limitation. Only a
handful like ASUS and ABIT has managed to extend the FSB barrier further with
their engineering expertise. However, least to say, the 925X is still far to be
an ideal board for enthusiasts especially overclockers without the presence of a
true PCI-E lock that will propel the board to its best potential. The other
factors are the high latency/low performance issue of the DDR2 SDRAM as well as
the lack of PCI Express graphics cards in the market.

Certainly, Intel should have more or less anticipated the
situation right from the start and the plans of a succeeding chipset, the 925XE
was planned months back. Intel finally launched the 925XE chipset in late
November that officially supports the 1066Mhz FSB along with the Pentium 4 3.46
Extreme Edition. Since the 925XE chipset is required to support higher FSB,
therefore the chipset is designed to sustain high FSB with the presence of locks
and better signal integrity. This is some sort of a good news for the
enthusiasts and overclockers alike. This motherboard we are going to look at
today, the P5AD2-E Premium probably is one of the most features packed
motherboard around. This board will take over the success of the P5AD2 series
out there and is set to continue the reign in the enthusiasts market. It comes
with Dual Gigabit LAN, Wireless G, 8 SATA channels with RAID, ATA-133 with RAID,
Intel HD Audio with C-Media 7.1 codec, 3 Firewire ports, 8 USB 2.0 ports etc.
Not forgetting, ASUS has a slew of overclocking features and BIOS options that
will blow you away. Since we have got hold of a Pentium 4 570J 3.8Ghz processor
based on the new E0 core stepping, we will test out the performance and
overclockability of this new processor against the Pentium 4 3.46 Extreme
