Now let's see how well this motherboard overclocks! We
used an AMD Athlon 550A (A = .18 micron) CPU. The CPU clock multiplier is
auto detected by the other board, therefore the only item that I could
manipulate is the FSB settings via a dipswitch. Another unfortunate
omission is the ability to control the core voltage of the processor.
Having said all of
that, I have some great news! This motherboard is a great
overclocker! Using the same CPU and the same cooling, I managed to
overclock it to 633Mhz with no voltage tweaks (2.75x115Mhz DDR =
633Mhz.) All of our previous motherboards
did not allow for overclocking above 110Mhz DDR.
I swear it's really a 633! WCPIUD is not 100%
These numbers indicate the obvious... 633Mhz is faster than
Once again, the 33Mhz difference is clearly shown here.
VIA's chipsets have always been plagued with slow memory scores,
this motherboard is no exception.
crucial features for overclocking, the GA-7VM has still
managed to exceed my expectations in regards to overclocking and
stability. Successfully overclocking to 115Mhz FSB is uncommon
(throughout my experiences) with all AMD Athlon motherboards, so naturally I was
quite surprised when it worked. Now lets try it out with a
