    Vcore vs CPU Core Voltage (SVI2 TFN) - Ryzen 5900X 1.47v Vcore / 1.52v SVI2 TFN / 1.50v VID

    Interesting observation. The question for Martin is whether this is likely due to increased accuracy within HWiNFO, or whether something else is at play. Which LLC setting are you using on your board? @Martin I've contacted AMD and asked about SVI2 TFN (core) and they've stated the values...

    Vcore vs CPU Core Voltage (SVI2 TFN) - Ryzen 5900X 1.47v Vcore / 1.52v SVI2 TFN / 1.50v VID

    Here's an update. The SVI2 TFN went outside of acceptable limits briefly - see post above - and then I reset and enabled logging for nearly 3 hours. All of this running a constant CB R23 single core benchmark. Here's some data, including using the excellent tool made by Thomas Barth. I can't...

    Vcore vs CPU Core Voltage (SVI2 TFN) - Ryzen 5900X 1.47v Vcore / 1.52v SVI2 TFN / 1.50v VID

    Update: on stock (as explained above), with Cinebench R23 single core, it's so far showing this :confused: : I've set it to run for 400 minutes and will update this thread when I check on it.

    IMPORTANT Explaining the AMD Ryzen "Power Reporting Deviation" -metric in HWiNFO

    Using the Asus B550-E "Gaming" WIFI with stock settings (only AMP/XMP/DOCP enabled), HWiNFO is reporting values between 89.7% and 256.2% - the latter figure is confusing as it's not (I believe, and apologise if incorrect) covered by the fascinating write-up in the opening post. The Asus board...

    Vcore vs CPU Core Voltage (SVI2 TFN) - Ryzen 5900X 1.47v Vcore / 1.52v SVI2 TFN / 1.50v VID

    Thank you for the reply - I truly appreciate it. - It's set to 1x. The only thing I touched under PBO is the Curve Optimiser - everything else was left on stock values or disabled (power limits, AutoOC, etc.). - I've just reset the BIOS again to see if maybe something went wrong last time (I...

    Vcore vs CPU Core Voltage (SVI2 TFN) - Ryzen 5900X 1.47v Vcore / 1.52v SVI2 TFN / 1.50v VID

    Here's another screenshot. This one shows maximum voltages and temperatures from just running Cinebench R23 single core on a loop four times (as well as having a couple of programs open). Again, the SVI2 TFN is above 1.5v.

    Vcore vs CPU Core Voltage (SVI2 TFN) - Ryzen 5900X 1.47v Vcore / 1.52v SVI2 TFN / 1.50v VID

    Hello, My PC is only a few weeks old (there are no old components in it) and I have recently found the CPU requesting too much voltage, and it being supplied with too much (as per AMD specification for the 5000 series). Which measurement is more accurate? I should note, that this is with PBO...
