P4s800/SIS648 Chipset: MuTIOL Technology

This board supports Hyper Threading with the proper CPU and PC3200/DDR400
memory but does not offer dual channel memory support. At least not in the
manner I've seen it offered on other boards. This 'MuTIOL Technology'....is
this an attempt to approximate or accomplish dual channel memory
performance?

Thanks,

There was a time, when motherboard Northbridge chips had a PCI bridge, and
the PCI bus that came from the Northbridge, was used to access the
Southbridge and all the PCI cards via that same bus. This limited the
available bandwidth between the Northbridge and Southbridge.

To address this, the new generation of chipsets used faster, proprietary
busses between the Northbridge and Southbridge. The Southbridge then
got the PCI bridge interface, so all the PCI cards hang off the Southbridge
instead. This can allow faster than PCI speeds when accessing interfaces
contained in the Southbridge.

Mutiol is SIS's proprietary interface between Northbridge and Southbridge.
It has nothing to do with the memory interface.

In terms of options, the 648FX on the P4S800 uses a single channel
memory interface. This can cause problems, like on any chipset, if you
try to drive a board full of memory DIMMs at DDR400 rates. There are
two other SIS chipsets, the 655FX and the 655TX, that support dual
channel. These are on the P4S800D and P4S800D-e respectively. The dual
channels give you two buffered memory interfaces to work with, so it
is easier to drive memory at DDR400 rates, if you don't have as many
loads on the memory bus.

Also, visit the forums at abxzone.com and search on the model number
of your motherboard. You can find out whether a board is a dog
or a winner over there.

An early review of a 655TX motherboard is here. I hope this isn't
indicative of how overclockable an SIS chipset is:

You can also download the motherboard manuals from the Asus site,
and read before you buy.

Paul,

Thanks for the info. The board will be in a system that will not be asked to
do anything out of the ordinary, no oc'ing or heavy gaming. The board will
be in a box for my daughter. As long as the box has good speed, she won't
really care about the lack of dual channel memory. I'm going to put P4
2.4MHz cpu in it with HT enabled and 512mb of DDR400 memory. That should be
fast enough for her.
