IMPORTANT Explaining the AMD Ryzen "Power Reporting Deviation" -metric in HWiNFO
- Thread starter The Stilt
- Start date
I have a brand new 5800x and an aorus b550 elite v2. While on idle the power reporting deviation ranged from 80% all the way down to 9% in one occasion. Under load(using cpu-z) it went up to 116% momentarily. Could a bios update fix this or does it seem like a different issue/defect? Thanks in advance.
Edit: Updating my bios to the newest version (FGd) didn't help, it's still all over the place.

CPU-Z is loading the CPU to 100% very briefly if you clicked the "Bench CPU" button.
Use either the "Stress CPU" or another synthetic stress test like OCCT for at least 10 or 20 min.
On idle or on very light stuff like browsing, watching vids and such the PowerReportingDeviation is all over the place and doesn't mean anything.
On idle/light load
Start your stress test and then right after reset values of HWiNFO by clicking the clock down on the right.
While the test is running for at least 10min, take the screenshot and post it here
It will look like this

Hi @ all,
I am new to this forum. I tried to search and read to solve my problem but I was not able to find something maybe somebody of you can help me. I am searching for a solution for so long now.
Since two weeks I have problems with my pc. Sometimes my games are lagging. The FPS are going from 100 to 5 and back to 100. This even is noticeable when I am on the desktop or surfing in the web.
In the video you can see that the cpu busy time spikes to 200 ms every 2 or 3 seconds. After a restart my pc the problems is often gone, not every time. I can not replicate this problem. What makes it hard to test for solutions.
Now I stumbled across the power reporting deviation. Under 100 % cpu usage (I ran cinebench R23) I have 64,9%
Is this linked to my problem?
My pc config:
AMD Ryzen 5 3600XT (did a stresstest 30 min with cinebench r23)
Nvidia RTX 3090 ti (did a stresstest with 3DMark)
4x 8GB RAM (already tested with Memtest86, no problems found)
Gigabyte B550 AORUS Elite AX V2 (latest bios installed)
Be quiet Bronze 700 W power supply
(I know that I have a CPU bottleneck but Tuesday everything worked fine and Thursday after the computer was off the problems started)

Hello, upon hovering above the red number, hwinfo told me to make a post here. How serious is this?
CPU is a Ryzen 5 5600 on a MSI B550M PRO-VDH motherboard.
I dont know if this is important, but i kept hwinfo running in the background for the day, only demanding task i did was gaming.
I upgraded my PSU yesterday to a Be Quiet Pure Power 12m 850watt
But you missed the rest of the "Important Note" that is in the description of this sensor....
I dont think that this issue has anything to do with Power Reporting Deviation beeing 65% under full CPU load.
The 3600XT is a 105W TDP CPU which means its a 125W PPT.
On your screenshot we see a PPT of 74W with PRD at 65%
So it goes like this:
74 (W) divided by 0.65 (65%) = 113.8W
The true power consumption (PPT) of the CPU is 113.8W and it is within the 125W default limit.
On another matter, I noticed that your FCLK and UCLK speeds is at 1330MHz. Is your RAM is also running at 1330MHz (2660MT/s)?
