Other standard features include a IDE RAID
controller, 7.1-channel Intel 'Azalia' audio, four SATA headers, eight USB2.0
ports, and two onboard Ethernet LAN connections; the first Gigabit and the
second a 10/100 NIC. The board features four 184-pin DDR sockets which will
support up to 4GB of PC2700/3200 RAM, two PCI Express x1 lanes (250MB/s
bandwidth), two PCI slots, and the aforementioned AGPe and PCI Express x16
slots. With a front side bus of either 533MHz or 800MHz, any speed of Intel
socket 775 'Prescott' Pentium 4 processor is supported.
Around back on this full size ATX board, are the I/O ports. The only
ones really worth noting are the twin network adaptors, and 6 mini-headphone
jacks which work with Intel's 'High Definition Audio' codec, otherwise also
known as 'Azalia.' Intel's HDA is a move to improve the sound we used to be
getting from puny little AC'97 codecs, and it really does make good strives in
that department.
Heatsink and Socket
775
As you know, socket 775 heatsinks
are significantly larger than the old standard socket 478 cooler was. Because of this
thermal solution increase in size to roughly 90mm in diameter, you may notice
that good motherboard manufacturers use higher quality electrical components around the CPU
socket - technically called 'Socket T' - which have a compact size necessary
to keep them close to the socket, and out of the way of the heatsink.
The capacitors for example are like the kind found on videocards, due to
a low profile requirement so they can remain under the edge of the heatsink.
Also, the EMI filters typically used on motherboards (a ferrite toroid wrapped
in copper wire) have been substituted for a higher quality, low profile version
that sits flat on the PCB surface (the flat gray cubes in the picture below).
These
components are used on the Albatron PX915P-AGPe, and fulfill their role in the
supporting circuitry for the Prescott Pentium 4 processor, and for providing a clear
space for the heatsink to mount. It may be worth your
while to be a little wary of motherboards which use more generic parts
here...
Power Connections
In the
long list of components which Intel engineers specified for the new processor
formfactor, is the 24-pin ATX power connector. With the spirit of backwards
compatibility in mind, the Albatron PX915P-AGPe is compatible with
standard 20-pin ATX power supplies. So, for
the moment you do not need to upgrade your power supply either, though
you will need one with the 4-pin auxiliary 12V connector.
With both
the 915P and 925X chipsets placing a
lot of emphasis on Serial ATA devices, we were pleased
to see that
the Albatron Mars
PX915P-AGPe includes an IDE RAID controller, and two extra IDE channels for a total of
four SATA headers. IDE drives will continue to live on for quite some time, and
this also allows users to move their old hard drives onto the PX915P-AGPe without having
to buy an additional PCI-based IDE controller.
Last but
not least are the four DDR memory slots for dual channel RAM. The Albatron Mars
PX915P-AGPe uses standard DDR RAM instead of the more expensive
DDR-2 memory. Yet one more component users can utilize from their older systems
as the switch from socket 478 Pentium 4 to socket 775 Pentium
4 is made. Now let's take a closer look at those two videocard
sockets!
