AMD Says Ryzen 1700X, 1800X Have a Temperature Reporting "Offset"
AMD is now saying reports of poor thermal performance from the flagship Ryzen products can be attributed to a simple thing: Temperature Offsets. Apparently, to keep a "consistent fan policy," AMD has placed a 20C offset on the Ryzen 1700X and 1800X products, making them report temperature a good 20C above what the sensor reads. This interesting design choice may most assuredly be confusing to end users, but AMD is confident software will soon automatically adjust for this offset and report the true temperature when required.
In the same blog post detailing the changes on the 1700X and 1800X, AMD claims that temperature reporting "may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value." This could mean other future models would utilize a similar setup, so remember that moving forward with AMD's Zen-based lineup.

edit: sarcasm alone is pointless so i thought i'd explain, but i see TheLaughingMan has already expressed my reasoning just fine :)
people are going to be upset/glad/resentfull >>>>> take your pick :)
The problem is that a little over it wont even boot properly in a lot of cases, so I highly doubt this will do anything for more overclocking potential.
this smells of amds marketing spin
why TF would you adjust the sensor +20 fracking C to tune the fan profile
what are fan curves too hard for AMD engineers to understand go figure
there is no fracking way there is that much of a difference chip2chip
"This a dangerous game you're playing, Damaskinos"
Damaskinos being the AMD in this case. :D
Errata? There is really some background story behind this... more like a skeleton in the closet.
See, I know what temps I should get based on what my cooler is capable of, and what I see if temps reported a bit low. It could be the board, for sure. ASRock Taichi isn't currently rated as one of the top picks for Ryzen for no reason.
If what they want to do is have a consistent level of reporting from all chips, it would make sense that each chip has its own offset, and that it is hard-coded into each chip itself. That would really make it not fishy at all.
This 4.1ghz wall seems like Bs too..
It is a huge success. It got rid of iGP, and instead gave us usable cores in mainstream platform, for users that do not use onboard video (which would be most of us here).
It is low on frequency, but to expect similar clocks as Intel from AMD's fab partner simply does not make any sense, so anyone that expected Ryzen to really compete with Intel are ignoring a fair bit of reality here.
And with those in mind, AMD did pretty good. Ryzen is pretty damn close to some of Intel's offerings. I evne think, had Ryzen been made on Intel's processes, that it would beat Intel easily.
But the fact remains that AMD will NEVER have silicon as good as Intel's, and as such, will always be slightly behind when it comes to clockspeed. IPC is great as is, anyway.
We can talk about temperature things, scheduling things, memory compatibility, whatever....none of which are really big issues. Yes, there are some things there that seem a bit funny with each of those parts of Ryzen, but none of them really affect how it works... the memory thing is easily solved by buying the right sticks. Scheduling... can't be fixed, IMHO (and AMD agrees it seems). Temperatures? What about Intel's TIM? These are all non-issues.
It seems Linux sees ryzen much better assigning L3 to each core group.

Definetly a windows derp. They will patch it.
2.) Why can't AMD have 'silicon as good as intel"? They walloped the shit out of them with the Athlon Xp and the base Athlon 64 run(By making really good design decisions). This is an excuse for a lackluster product that is simply compensating for poor design choices, rather than holding their feet to the fire like people hold Intel to. Multi socket boards do 'show this issue', but NUMA is important because the memory controllers are physically separated from CPUs(N.on U.niform M.emory A.ccess). Numa issues do not apply to Ryzen because they are all bound to the same pair of memory controllers. (Besides, Windows has been NUMA aware for a long, long time at this point)
ccnuma is a potential issue, but re: scheduling, AMD has cleared the air entirely of all scheduler issues. There is nothing to fix.
The real issue is just the reality of using a low speed CCX between quads for AMD.
