The MA78GM's advanced BIOS tweaks are housed in the poorly named
"MB Intelligent Tweaker" menu. It's a bit spartan, but that's how
we like it. It offers everything one needs to get the most of out of their
system without getting extravagant. A few boards we've looked at in the past
had a maze of settings with strange terminology undecipherable by all but
the most accomplished enthusiasts.
"MB Intelligent Tweaker" maximum voltage and frequencies
CPU frequency and voltage are given free reign with their extremes
values likely never to be used. The maximum memory voltage of +0.3V (2.1V)
is very low when you consider that a good number of high speed DDR2 memory
kits require 2.2V to run at their specified speeds/timings. Fortunately we
later found that the memory is slightly overvolted.
Notable Available BIOS Adjustments
||200Mhz to 500Mhz in 1Mhz increments
||DDR 400/533/667/800 (depends on the processor
||0.8000V to 1.5500V in 0.025 increments,
1.5500V to 1.9000V in 0.05 increments
||Normal (1.8V), +0.1V, +0.2V, +0.3V
||Normal (1.1V), +0.1V, +0.2V, +0.3V
|Video Memory Size
||AUTO, 128MB, 256MB, 512MB
The "PC Health" menu is also fairly straight forward. CPU and System
fan control can be enabled or disabled no target temperatures or ramp up
thresholds and can be designated here.
