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.

voltageas a whole, they have NEVER lasted as long as Intel's CPU's and board chip sets, FACT. are you not aware? then go do your own research.
From the same company that said 1.5v is perfectly safe no less! No worries. AM4 can support Zen 3 after their old one dies!

My 1100T begs to differ. Also all these products are aged before they would die. So, poor troll.....poor poor troll.

I have had 2 boards fail on me, in 15 years, both Intel. So you need to redo your research.

Say that to the over 10 Sempron LE-1150 I have.
Only AMD CPU that died on me so far is a K6/2.

My pencil-modded Athlon XP "Palomino/Throughbred/unsure" kept ticking for 8 years after the mod as my NAS. It should still work, I only took it apart because I didn't need it.

But yeah, no. This is nearly impossible to prove.

My brand new Phenom II X4 970 that I unlocked and overclocked to 4 GHz with 1.425V. It’s still functional in the parents HP desktop with a moderate overclock using MSRtweaker.

The only AMD CPU that ended up a casualty was caused by a Gigabyte motherboard blowing a MOSFET.

I remember Linus Tech Tips once saying he has never seen a CPU just die. Like ever, any brand. Unless it was DOA, or something was wrong with mobo, power supply, or just straight up like liquid helium oc killing it.

I mean he has seen thousands and thousands of CPU in his days. This thread needs to be locked

I had a cooler removed from duron 800 in windows just to see whaat happens,didn't die or spitfire

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"

could mods just remove the first comment and the subsequent responses....its not very helpful and just spread mis-information.

though I do love the "do your own research" remark, like they cant even link a single article to back up their claim lol.

I have seen a few dead CPUs over the years, some from delid attempts, drops, unsuccessful pin repairs, etc - those are all physical damage caused by the user. SMDs can get knocked off the back of CPU - I heard of this twice, once where someone probably inserted the cpu wrong initially and once where an SMD came off after overheating due to a bad cpu cooler... hard to say in that case, maybe the heat weakened the SMD/solder before the processor was removed and checked. FWIW, both of those cases were intel chips from long ago.

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.

this is such a dick move,says it all that a person has no idea what he's talking about.probably will link a completely unrelated video in 2 days and continue the charade.
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.

Never seen any dead CPU unless it was a dud from beginning, or overclock without proper cooling and sufficient PSU's :D
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

Just a funny coincidence - got my first batch of dead 1st gen Zen processors just in a past month or so. Always thought that it's impossible to kill those, but a couple of R3 1200/1300 died from overclocking, and the rest simply died on their own. Had hard time diagnosing one of my customer's PCs, where no OC was in play and dude actually knows what he's doing, but after a year or so it started BSODing like crazy, with random errors from memory faults to I/O initialization faults.... At first I thought it was a faulty PCH, since it works fine booting off flash drives or in BIOS, but juggling around SSDs/HDDs/NVME SSDs/ PCIe SATA controllers did not change the outcome. Trying another RAM also did nothing. Then we've got another sAM4 test board and..... nothing :twitch:
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).

And admittedly you've seen how many CPUs would die/died off when the MB lied to the CPU about power consumption? Do note we don't even know how many boards lie & what is the power delta leading to consistently excess heat &/or reduced lifespan!

damn that's crazy early for a 2017 cpu to go

Some of you and Linus aren't trying hard enough, I've blown the shit out of 3 CPU's all three took EXTREME voltages to kill them, lot's of frequency and not quite enough cooling:) ;) :D.

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.

I've broken a few Intel CPUs in recent years with heavy overclocking. If I remember right, a Haswell Pentium G3258, 3 Skylake CPUs. Verified using other boards, ect in my lab that it was indeed the CPU that died. I think I have only killed 1 AMD CPU, an Athlon II x4 620, and I could not verify that because I did not have another board on hand to test at the time. I did however, run an FX-4100 at 1.65v 5GHz for years in what started as a suicide run but just kept chugging along...

No CPU have died on me either.
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!

Replying to the Troll asking to "do my own research" ... ... I AM THE RESEARCH! :D

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

Have only ever had one CPU die, and that was a Celeron Coppermine 633Mhz which died during a numpty overclock gone wrong when I was a clueless teenager. On the other hand, I've got a working AMD K6/2 450 in a retro gaming PC going strong, and that thing is over 20 years old now. Honestly, CPU's are the most reliable parts of a computer, which is crazy when you consider how complex they are.

Still waiting on my first CPU demise ever...but I did see degradation a few times.

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.
