FINAL STEP
make sure it’s the right thickness
to keep the card straight. This is
a much bigger issue in four-way
SLI overclocking with those soft
bridges than when using the fixed
bridge. It should be done in both
cases regardless.

STEP SEVEN
Once all the cards are “shimmed”
and installed into the system,
grease the SLI bridge contacts
and install them. As a final note,
I will recommend that you use
a hair dryer or heat gun on that
whole bridge area/side of the
card while overclocking as there
is no heat generated in that area,
and it will freeze. Circulation of
air is important around the CPU
when overclocking using liquid
nitrogen. Keep the falling nitrogen
from freezing up everything
around the CPU container like
the PWM heat sinks and DIMM
slots throughout long sessions.
GPUs are not too different; much
more nitrogen is being used
more frequently so the air flow
around them is more critical. Use
a nice large high CFM fan for air
circulation on the PWM side of
the card. Of course when running
really high voltages, the PWM
can get very hot even if GPUs are
really cold so you can cool the
PWM like this as well.

Keep your HW running strong and
give it the chance to give you the
best results possible by preparing
correctly. Four way graphics
overclocking is in my opinion the
pinnacle of extreme overclocking
and I have always had the greatest
respect as an overclocker for those
that can do it successfully. I'm not
talking about cards cooled only by air
or mildly pushed in some outdated
CPU bound benchmark. I mean the
highest clocks possible the cards
are capable of in four-way using the
latest benchmarks that push the
most modern GPUs to their limits.
This is where it’s at. [PICTURE 14]
Good luck and most importantly
have fun!
