A dedicated 2GB/s
I/O bus connects the Intel P35 Express Express Northbridge and ICH9R Southbridge
together, which might be a little tight if you have many high bandwidth devices
installed but should be just fine for the average user. You will recall this
figure has not increased since the P965 Express chipset.
The Gigabyte GA-P35-DQ6 motherboard comes installed with
the ICH9R Southbridge which includes a ton of goodies.
six 3GB/s Serial ATA II channels (which support RAID modes 0, 1,
5 and 10) as well a 7.1 channel Intel Azalia high definition audio, twelve U480MB/s SB
2.0 ports in total (split between headers and the I/O slot), six PCI Express
x1 lanes at 500MB/s bandwidth each, and an integrated Intel Gigabit MAC that runs
through the PCI Express bus specific to this chipset.
Noticeably lacking from the
chipset itself is parallel IDE support. In this case, Gigabyte resorts to a
stand alone IDE controller to provide IDE support on the GA-P35-DQ6 motherboard.
A block chart of the Intel P35 Express Express chipset's major features is
Intel has integrated its Quiet
System Technology or QST into the ICH9 Southbridge. Essentially it allows
the chipset to throttle fans that are connected to the motherboard down to
quiet the computer. When QST detects that the system is getting too hot, fan
speeds will increase accordingly.
Intel’s Matrix Storage
technology encompasses RAID and eSATA support. The ICH9R Southbridge supports five
levels of RAID: 0, 1, 0+1, 5 and 10. Also supported is eSATA, and we are finding
most manufacturers placing at least one and sometimes two eSATA ports on the
Intel Turbo Memory is the
only truly new feature of the ICH9 Southbridge. Essentially it allows you to
connect a special Flash cache memory card to the PCI Express bus. It is
supposed to improve application and data loading of the computer by off-loading
recurring HDD tasks to the Flash memory card. At the moment Intel’s Turbo
Memory technology is aimed at the mobile market where hard drives tend to be
