/ Setup - The GA-6CX i820
edge Intel technology with a
GA-6CX was transplanted into our main test-bed
system which historically was on a BX chipset
based motherboard. From there it was clear
sailing. The board has a dip switch that
allows you to set the CPU FSB and a jumper to
allow for 10% overshoot of the CPU core voltage.
You can of course enable or disable on board
sound. This is done via the
there are no settings for CPU frequency in the
BIOS but the DIP switch approach proved to be
easily accessible. Speaking of the
BIOS, the GA-6CX has AMI BIOS on board which we
have found to be more and more of a rarity these
days. However, this BIOS was very full
featured and intuitive as well as easy to
use. A nice feature on it was the single
key stoke set up of all drives in your system
with the Auto Detect feature. This feature
even detects CDROMs.
the board comes with lots of health monitoring
options including fan speed and temp sensors for
both the system or ambient air inside the case
and the CPU itself. These can be enabled
or disabled in the BIOS and there are threshold
values that can be set for each, sounding an
alarm should a critical spec deviate to far from
the limit you set. All told, this is a
very easily configurable board with excellent
compatibility, as far as our test were

the way, here is a shameless plug for the good
folks at TECHWORKS!
They are one of the few manufacturers of Intel
certified RAMBUS RIMM modules. Plain
and simple, they rock!

only did the Pentium!!!533B we used,
overclock easily to 600 MHz. but stability at
default voltage was perfect. This was
something that we have not been able to
accomplish on all motherboards we have tested
with this CPU. Furthermore, if your CPU
needs an extra voltage boost to remain stable
when overclocked, the board does have the
ability, as we noted earlier, to set the core
CPU voltage 10% higher than the CPU

are available via the dip switch settings, which
limited our Pentium to 600MHz. Perhaps we
could have overclocked higher with more
available high speed FSB settings. The
fact that this board utilizes RAMBUS as its main
system memory, gives it an enormous amount of
margin for FSB settings up through 400MHz and
800MHz aggregate bandwidth with Double Data Rate
(DDR) capability. Furthermore, any new
Intel Camino based motherboard with RIMM support
will have this type of headroom. An FSB
setting of 200MHz. with a 1 GHz. Intel
processor, is something that will finally begin
maximize the effective bandwidth of RAMBUS.
the GA-6CX is a competent overclocking set up
with excellent stability.

from Intel could muster. Furthermore, we
wanted to see what our shiny new 128 RAMBUS RIMM
could do for us in terms of a performance boost in
main system memory. In the following tests
we tried to focus on three things, processor
performance, main system memory performance and
drive sub-system performance. We intended to

have found to date, that will measure main system

does the best job in isolating the performance

for larger view)
can easily see in this head to head test of a BX
based motherboard with PC133 memory and the
Gigabyte GA-6CX motherboard with RAMBUS, there is
only a marginal performance gain while using
RAMBUS at an FSB of 150MHz. Again, we feel
higher speed Front Side Bus settings are needed in
order to see real gains in performance using
RAMBUS. In addition, RAMBUS should provide
excellent stability at just about any Front Side
Bus speed imaginable in the future.
CPU figures are pretty much neck and neck with
perhaps a slight edge going to the GA-6CX.
