Playing high definition content on current generation PCs can bog down
even the fastest processors because there is more data to
handle. To test AVIVO's HD accelerating
capabilities, we played the High Definition 720P Blu-Ray movie The League of
Extraordinary Gentlemen through CyberLink PowerDVD 7.2 Ultra.
CPU utilization was monitored during playback through Task Manager to give a
general indication of system load. CPU used for PureVideo tests was the AMD Athlon64

720P Resolution no
ASRock, PureVideo especially with an integrated videocard is very heavily
CPU dependant. In fact ASRock recommends an Athlon64 X2 5200+ (and
min. 2GB RAM) when viewing H.264 High Definition movies. In any case CPU
usage with nVIDIA PureVideo enabled generally
jumped between 55-65% which is much higher than we're use to.
Surprisingly when nVIDIA
PureVideo is disabled, CPU usage actually goes down
and hovers between 45-55%. It's possible that PureVideo does not like to
share memory between the CPU and onboard videocard. In any case no
matter what you run, CPU load still allows applications to run in the background
while providing smooth video playback.
Motherboard Overclocking Chart
Overclocking is alive and well! PCSTATS
has all the details you need to see at a glance to know which board is best. The
chart we've compiled below lists the highest overclocked Front Side Bus speeds
we were able to achieve while maintaining 100% stability.
Typical Test System
Specifications: AMD Athlon64 X2 5000+, 2GB Corsair Twin2X2048-8888C4DF
DDR2 Memory, MSI NX7800GTX-T2D256E. Please see individual review for more
specific test details. If you're new to

things considered, the ASRock ALiveNF7G-HDready motherboard overclocks well
for an integrated motherboard! Too bad there are no chipset voltage
