I am not talking about instability. You said that undervolting an IC can damage it.
Got a tip for us?

I wrote it badly. The instability was for the undervolting, the damage was for overvolting.
There is a special case though when it comes to mosfet. Some can be damaged by undervolting since their gates aren't meant to be partially on or off which they'll be if not enough voltage is applied.
When this voltage is too low to turn the mosfet fully on a dangerous situation (from the point of view of the moseft) can arise: when it is half-on, both the current through it and the voltage across it can be substantial, resulting in a dissipation that can kill it. Death by undervoltage.
Yes, low voltage can damage some electrical circuits.
But it will be hard to find a case where undervolting has killed a graphics card or a CPU.
^This makes me think that it's actually insane we don't have some automation or AI in these cards.
We have AI who can beat the best gamers but a damn GPU can't just tweak itself based on temp or other basic variables.
GPUs already optimize themselves. They have many power states and they manage themselves depending on their power ceiling, temperatures and frequency limits. This is why base/boost frequencies are almost meaningless these days as it will simply clock itself up and down depending on workloads and thermal headroom. For instance Vega FE rarely hit its maximum frequency out of the box because of thermal limits.
AI isn't a magic wand that makes everything better/faster. The only thing I could think of that machine learning could do here would be to better predict when performance is needed/not needed. For instance it could detect when a player is aiming in a first person shooter and then ramp up clock speeds then. This is similar to what Radeon chill already does where it down clocks when the mouse isn't moving.
I had bought an RX 460 without PCIe socket for my Akitio and only played with power management when using it with the Mac, with my Skylake laptop it worked without any issues.
Then I put it with the default config in the Phenom II PC.
Now I went and adjusted voltages, with the top state reduced by 60 mV. I did not touch the core clocks, left it as dynamic.
I also overclocked the VRAM by 200MHz without touching voltage.
As a side effect, I noticed that the default fan speeds seemed too low, so I raised the low end by a couple hundred RPM.
I did not increase the power budget, as I am not overclocking the cores and the card is fed by the PCIe slot.
On Vega 56 it is very easy to also just overclock the VRAM somewhat for a good boost, as the configuration looks gimped for upselling to the 64.
The 64 seems more controversial than the 56.

Looks like the Vega pricing was deceptive, as the $400 and $500 price points were only discounts for launch day. The article even quotes suppliers saying its because the margins on it are so thin. This is not surprising at all, given that its a large die on expensive interposer technology using expensive memory. It really needed to compete with the equivalently sized GTX 1080 Ti and its not remotely close.
This has to be one of AMD/ATI's worst GPU launches in quite awhile. Poor performance, low availability, a full year of hype, deceptive prices. Compute may be the one thing they can sell this card on. Lets hope thats enough to get them through to the next generation and Navi is something that can get them back in the high end game.

You forgot "catastrophically bad performance per watt" as well.
Can't wait to see if the Imac Pro comes with lead weights so that the fans don't lift it off the desk.

Stock market manipulation and shorting has a too big influence on company innovation now. We need to stick all global assets on to public blockchains to identify and prevent people who form financial cartels to manipulate markets and politics.
I have deleted several posts from this thread as they were little more than off topic bickering. Can I please ask that people stay on topic and don't resort to bickering. Thanks!
I have been an AMD apologist for a long time. However, I cannot support this new price hike. I will continue to hold off on Vega until the prices stabilize, but charging more than a GTX 1080 is just more than I can stand.
"At the end of July, KitGuru was one of the publications invited to SIGGRAPH 2017, during which, AMD finally unveiled RX Vega to the world. At the time, we were given a $499 MSRP for the RX Vega64, which we were told should work out at around £450 here in the UK. What AMD failed to disclose was that this was intended as a ‘launch day only’ price, causing undue confusion for buyers, putting unnecessary blame on retailers for ‘price hikes’ and even potentially skewing the conclusions of early reviews."
Yep they did.
That is just a rumor, and as I said, a price hike would be expected outside of USA because $499 does not take into account VAT and markups overseas.
Here is AMD's official statement:
This certainly looks bad and this vague statement doesn't help much. My guess is its simply a way of getting more money while supply is low, somewhat like Nvidia's founder's edition. The difference is Nvidia was very up front about it.

Videocards.com says the official statement came from here: https://www.io-tech.fi/uutinen/amd-...-rx-vega-64n-hinnoittelusta-ja-saatavuudesta/
I more or less expected a link (in English) to an AMD website.
Punish them. Never rewards corporations for doing things like this otherwise they will push for more money and ******** products next time. Just like Apple has done to us so many times.
No that's the price AMD announced at Sigraph

$399 AND $499 are US prices. 459 pounds is less than $499 + VAT and also does take into account hedging.
