the grown ease of video card overclocking, it has become hard
to avoid overclocking your prized Quake3 video powerhouse. With
easy to use overclocking programs freely distributed over the
Internet, it almost raises the question "Why not?" When heat
becomes too much for your video card, the beautifully rendered
games that once flew by, will get texture corruption, discolored,
and cease to run all together.
the chipset rarely has a problem, much like the RAM it can prevent
you from hitting a higher FSB. Rarely will you see a motherboard
equipped with any more chipset cooling than a small heatsink,
dubbed "The greenie."
testing has the widest variety of options. Including standard
benchmarks like Sisandra, to specific stability programs, as
well as distributed computing like SETI, and Distributed.net.
Used in this guide, is a handy programmed by Passmark titled
BurnIn, and a distributed computing client named Prime95. BurnIn
is designed to specifically test different CPU operations, so
that all elements are stressed and tested, such as high L2 cache
usage, and integer operations. The stability of L2 cache needs
closer attention on older processors, with on-die cache, this
tends to no longer be a problem. Katmai Pentium 2's and Pentium
3's have off-die cache, which tends to be unstable at higher
speeds. After these two tests you will know that every aspect
of your CPU is stable. To insure absolute stability, it is recommended
that you run this high stress application for 24-hours. This
process is commonly called "Burning in". In some situations,
there have been reports of burning in allowing lower voltage
levels at the current overclocked speed as well.
Prime95's formal function is to participate in a community distributed
computing program, it has a function dubbed "Torture Test".
This option does just that, tortures the CPU with incredibly
high stress levels. Prime95's torture test has been known to
find instability were all other programs fail. Many professional
OEM Computer builders use the torture test as a stability guaranty.
