A new build of AMD Ryzen Master (version 2.0.1.1233) is also available for download today, and it takes
all of the above changes into account. If you’re new to this utility: Ryzen™ Master is our first-party
monitoring and tuning application that can help you observe the behavior of your PC and, if desired,
tweak the performance as well.
In addition, the tool has been refined with two critical changes concerning voltage and temperature
monitoring.
For temperatures:
• OLD BEHAVIOR: Report the highest temp (“instantaneous temperature”) of any sensor in the
whole CPU, no matter how isolated or brief. This approach overstated the prevalence and
significance of fleeting peaks, which artificially inflated temperature reports by up to 30°C above
the true silicon conditions.
• NEW BEHAVIOR: Report a short-duration rolling average of all temp sensors in the chip. This
model will give you a holistic view of what the processor is doing across cores, cache, bus
interfaces, etc. It’s the closest any software monitoring tool can come to portraying the true
thermal conditions of the chip, and it’s the same model our own Precision Boost 2 algorithm
uses to make temperature-related boost decisions.
For voltage:
• OLD BEHAVIOR: Report the highest transient voltage in the whole CPU, no matter how isolated
or brief. This, too, overstated the prevalence and significance of fleeting peaks, which artificially
inflated voltage reports by as much as 800mV.
• NEW BEHAVIOR: Report the average voltage requested of the regulators, which presents a
“whole chip” view that factors in sleeping cores, idle cores, and active cores. This is the closest
any software monitoring tool can come to portraying the true electrical conditions of the chip,
and it’s the same model our own Precision Boost 2 algorithm uses to make electrical-related
boost decisions.
Altogether, this version of AMD Ryzen Master will give you an accurate view of what your 3 rd Gen AMD
Ryzen Processor is doing, using the same sources and methods utilized by our on-chip firmware and
internal monitoring tools.
ADDITIONALLY: We also intend to release new developer documentation that enables third-party tools
to take the same measurements, so you can continue to rely on your favorite third-party apps after
they’re updated. We will be contacting utility vendors directly with more details when the
documentation is ready.
