AMD Responds to Allegations of Ryzen Power Reporting Deviation Reducing CPU Life
AMD on Thursday posted its first official response to reports that the deviation in power reporting by the CPU VRM controller to a Ryzen processor against its actual power delivery may be shortening processor lifespan, sparked by HWInfo introducing the "Power Reporting Deviation" sensor. "We are aware of the reports claiming that select motherboards may be under-reporting certain power telemetry data that could alter the performance and/or behavior of AMD Ryzen processors under certain conditions. We are looking into the accuracy of these reports," the response begins.
AMD also clarified that Ryzen processors aren't dictated entirely by the power telemetry from VRM controllers. "We want to be clear with our customers: AMD Ryzen processors contain a diverse array of internal safeguards that operate independently of external data sources. These safeguards enforce the safety and reliability of the processor during stock operation. Based on our initial assessment, we do not believe that altering external telemetry in the manner described by those public reports would have a material impact on the longevity or safety of a user's processor." AMD's response also suggests that the company isn't aware of power reporting deviation or at least the extent to which motherboard manufacturers rely on tricking the external power telemetry setup to send more power to processors, in a bid to notch ahead in stock performance or overclocking headroom.

Only AMD CPU that died on me so far is a K6/2.
But yeah, no. This is nearly impossible to prove.
The only AMD CPU that ended up a casualty was caused by a Gigabyte motherboard blowing a MOSFET.
I mean he has seen thousands and thousands of CPU in his days. This thread needs to be locked
but yeah,I would rather see people demand to have mobos tested for this vampire power draw instead of the usual pages and pages of "amd can do right" vs "amd can do no wrong"
though I do love the "do your own research" remark, like they cant even link a single article to back up their claim lol.
Bottom line, it is extremely hard to kill a cpu outside of physically breaking it or extreme overclocking runs. I’d be more concerned about the board or cooler if something was causing excess power draw.
he could've at least linked us youtube.com and say it's a test for us that we failed,that'd make it more believable.
My unlocked and overclocked Sempron 140 @ 1.55v still in service as gateway server running CentOS, so unless any person dictating anyone to do research, kindly show us their version of "FACT" :p
So, he bought a used R5 1600 while old CPU is doing its rounds and hoops on RMA. Linus is a shmuck and an idiot. But the main point is he does reviews, not repairs. So, of course you won't see any dead CPUs if you are constantly rotating new hardware.
I can't tell you how many dead APUs I had to change on HP Pavilion/Envy laptops(especially A10-4800), or how many desktop 1155 Celerons/Pentiums died in pain and suffering due to internal shortage, or most importantly, how many sFM2+ Athlons got incinerated by mismanaging auto-voltage on cheap "updated" FM2 motherboards.
I am going to the office right now, I can snap my collection of deaddies that weren't made into keychains or nerdy pendants yet. I even have weird ones, like a 2500K that died on H61 board, and 2500S that "burned-out" over time due to sudden TIM separation from heatspreader (owner wasn't watching temps and only noticed when his PC started to BSOD and died).
To be fair to me I do like to push it, and they were all really old prior to death.
Once they're old it's game on imho time to torture.
Though also I have always ran high volta clocks etc all the time , I degraded processors without concern a few times, usually takes three years before it becomes noticeable and they don't then stop working, they just need slightly lower clocks or more voltage, by the time a tortured CPU displays issues, they're at the end of usefulness anyway.
Or begone.
All of them had been sold, altough motherboards it's a whole different story, I had 2 motherboards from Asus that died :)
Also I still have a Phenom II X4 945, that was Overclocked from 3.0 to 3.6 GHZ (1.35v -> 1.475v with LLC) since it made 2 years old.
It's still alive, and already have 10.5 years of existince, I also had an AMD Sempron in the past and a Pentium 4 2.66GHZ, none have died, even when overclocked!
My (still working and running daily) FX-8350, A8-7650K and Phenom II 965 begs to differ
Even my retired Athlons (just for being out dated) 5600 and 4200 also begs to differ
And I am expecting my new Ryzen 2700X, 2600, 1700 and 3400G to also follow suit
Then again I don't hoard old parts. It will be interesting to see when the 3570k says thxbai, running a mild OC all its life.
