X370 Gaming K4 - new BIOS with AGESA 1.0.0.6&a

When it comes to ram speed 3.00 it is a small improvement over 2.50

From what i have seen with this MoBo Agesa 1.0.0.6a is not worth it. i saw decreased performance and stability across the board wither it be memory or cpu clocks. I downgraded back to 2.5 and everything went back to normal. super stable on 3.9 on my 1700 overclock and 2933 on my lpx 3200 memory running at cas 14 instead of cas 16. 

Insanely good results for me on this version.

Hi again,

The 20° C offset in the temperatures is the difference between the two temperatures reported by a Ryzen processor, Tdie and Tctl (ctl = control). This is an AMD thing.

When using HWiNFO64 with my ASRock X370 Killer SLI/ac with a 1700X, it reports both Tdie and Tctl. The two have a consistent 20° C difference. HWiNFO64 only reports one of these with other boards for some reason, or labels a single CPU temperature "Tdie/Tctl".What your F-Stream or other ASRock utilities such as my board's A-Tuning reports is something else, which I don't understand.

At one time the difference between Tdie and Tctl was supposedly used for different Ryzen processors, and also somehow related to the use of the stock Ryzen CPU cooler. As far as I know, what Tdie and Tctl are used for, and which one is the correct processor temperature, has never been made clear.

My board's AGESA 1.0.0.6a UEFI update (3.00) also changed which temperature is used by the fan speed control feature in the UEFI. I use custom fan speed profiles with the FANTastic Tuning feature in the UEFI, and had to adjust them significantly with this change in the 3.00 UEFI. As said above, some ASRock Ryzen board users were complaining about which CPU temperature reading was being used by the fan speed control settings in the UEFI, and this change in the 3.00 UEFIs must have been based upon that.

Your F-Stream software most likely is programmed to use a different CPU temperature than is used in the UEFI, if it has not been updated along with the 3.00 UEFI. My board's utility has not yet been updated. In the past, the UEFI fan speed control and the ASRock Windows utility fan speed control have used the same CPU temperature to control the board's fan headers.

One problem with fan speed control is all PC fans are different in their minimum and maximum speeds, speed/RPM vs PWM % or applied voltage, and starting PWM % or voltage. Also fan speed vs applied PWM % or voltage is not always linear, and the speed where fan noise is bothersome is basically random. I actually changed two chassis fans in my Ryzen PC after I applied UEFI 3.00, since the fan noise was bothering me.

IMO, the Ryzen CPU temperature reading and fan speed control relationship needs a bit more work. But using the predefined fan speed profiles will be pure luck if they match your fan's RPM, speed range, and noise parameters, and your personal usage and ability to live with fan noise. I have yet to find an AIO liquid cooler whose stock fans are not loud at or near their maximum speed.
