AMD Ryzen Master Software v1.0.1 Update To Fix CPU temperature Reporting

A new update (version 1.0.1) of the Ryzen Master overclocking utility is now detecting Ryzen CPU temperatures correctly when compared to the previous version. Some users have reportes issues when using AMDs Ryzen Master Overclocking Tool to monitor temperatures of their Ryzen CPUs.

Many people complained that they were getting 60C to 70C degrees idle on their Ryzen 7 1800X, 1700X and 1700 CPUs but it turned out to be an issue with reporting. Ryzen Master was using an improper tCTL offset temperature for fan reading, and that one is 20c degrees higher than the original junction temperature. This only applies to the 1800X, 1700X and upcoming 1600X processors. AMD explained this issue on their community update on March 13 where they stated:

"The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature—the interface point between the die and heatspreader—but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen™ processors have a consistent fan policy.

Specifically, the AMD Ryzen™ 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically."

The new updated version of Ryzen Master utlity detects the true junction temperature. This should help more people to have an idea about their cooling performance and adjust their voltage for overclocking.

Ryzen Master version 1.0.1 is not available just yet but it will launch on April 11th, which is the same day the new Ryzen 5 CPU lineup will launch. Below is a screen shot posted by AMD comparing the temperature before and after the update.

All I can say is about time. Yes they have their hands full currently, but this is output by them. The fact the cpu's had an offset that their own software did not take into account shows how poor their internal communications are.

So where is this alleged update? it's not on your download section and AMD's site still has version 1.0.0.0227.

It is not yet available will be release April 11th, Hilbert stated that in the write up. The OP gave a misleading title and sentence.

" Ryzen Master version 1.0.1 is not available just yet but it will launch on April 11th, which is the same day the new Ryzen 5 CPU lineup will launch."

Pretty crappy reason for not having an accurate sensor reading if fan speed curves are temp based should you even need to have an offset or wouldn't the speed of the fan just ramp up as the Tctl increases or am I getting the wrong end of the stick if someone wants to explain further that would be great
