FEATURE / CUSTOMISATION


Overclock your graphics card
The Nvidia RTX 2060 Super Founders
Edition is an excellent overclocker, and it’s
simple to get some extra performance.
Download GPU-Z (techpowerup.com) and
MSI Afterburner (guru3d.com), increase the
temperature and power limits to maximum in
the latter, and then locate the small three-bar
button next to Core Clock.
In the window that appears, hit OC
Scanner in the top right, then select Scan.
This will begin to automatically overclock
and test your graphics card and is normally
fairly accurate in obtaining a core frequency
reasonably close to what you’d achieve
manually.You’llseethecorefrequencyin

CPUoverclocking
AMD’slatestCPUsaren’t
straightforwardwhenit
comes to overclocking. Their
all-core overclock headroom
is fairly limited, sitting at
just 4.3GHz on our Ryzen 7
3700X despite its 4.4GHz
maximum boost frequency.
While you’ll gain a couple of
hundred megahertz in an all-
core boost from around 4GHz
at stock speed, you’ll lose the
ability for the CPU to drop

backunderlowloads.You’llalso reduce its
lightlythreadedperformance, as its stock

FINAL SETUP


In Afterburner, locate the small three-bar
button next to Core Clock
Apply the memory XMP profile in the EFI to
set the correct speed, timings and voltage

MSI’s OC Scanner is great for finding a stable overclocked core frequency
