4.4GHz boost – this will give us good
gaming performance, while reducing power
when the system is idle.
Head into the EFI, go to Settings/
Advanced/AMD Overclocking, and find
the Precision Boost Overdrive option.
Select Advanced, set the PBO limits to
motherboard, then dial in 200MHz to the
maximum CPU boost clock
override. We found that, with
our setup, the all-core boost
increased from between
3.95-4GHz up to 4.15GHz
under load.
Our memory overclock
and CPU tweaking boosted
the RealBench system score
from 230,785 to 237,356,
and increased the Cinebench
R20 multi-threaded score
from 4,738 to 4,923.
Meanwhile, manual 4.3GHz
overclock saw a score of over
5,200 points in the multi-
threaded Cinebench test,
but a noticeably slower result in the single-
threaded test.
These tweaks, combined with our graphics
card overclock, increased the minimum
frame rate by 2-4fps in Shadow of the Tomb
Raider, and they only added 56W to the load
power draw of our PC, so it’s definitely worth
overclocking these components.
Use AMD’s Precision Boost Overdrive
software to get a gaming performance boost
