By design is impossible for the board components to have the same tolerance level as the maximum power draw capacity of the main chips. 15-20 years ago that tolerance level was only near 10% beyond the max capacity, now-days it can easily go between 20-30%. Most manufacturers started using military grade components after the capacitor plague specially for products intended for the overclocking the crowd, now every manufacturer use them, from the cheap Acer products to the luxury class of devices from Apple. If you don't know this, is because you're too young perhaps. You need to understand basic electric engineering, what a capacitor is, a resistor, and how the transistors unload and overloads these two constantly when you use your pc, to comprehend what really happens when you mess with the original clock frequency settings. Just a change of .1mv would alter the internal components bringing stability or havoc to the entire system. If you don't take into account the tolerance level, the system will shut down or crash. That is why Bios, usually disable some options or put limits to them. With your approach then Yes, you are controlling the power state from windows, but windows is making a predicted change to the bios settings on the fly. But, you are not doing anything out of the ordinary to what the chip was designed for. Except for what you said earlier about pushing TDP up, and for this is why I talked about tolerance levels, is a requirement and not a choice for proper functioning, specially when lowering voltage for higher frequencies which decreases amperage (if passive), and stresses capacitance; hence why capacitors are the first to be blown. (capacitor tolerance level was exceeded) |
Citation needed.
| alexxonne said: 2)Power states are just ACPI profiles. Just because you can play with Windows settings doesn't mean you understand what you are doing. But you are not an idiot, I give you that. While you can be clever sometimes, the tone you use in your writing...pufff, just blows your intended purpose. |
Bit of a stretch to assert that I don't know what *I* am doing when you are the one who stated they don't know much about AMD's platforms.
| alexxonne said: 3)Clearly the framing of my comments include my experience blowing stuff every time for testing purposes. After repairing lots of shit like this everyday, I know very well what I'm talking about. Computer enthusiasts like lots of people here enjoy the thrill of squeezing performance....until something goes wrong and burn their systems. But clearly you don't give a shit about that, so you don't know, but some other people do really. If by basic understanding you mean my Ph D, then yes, clearly is an issue you haven't found yet cause you are not that deep in to this as I wrongly assumed before. |
Your experience is entirely redundant. And not to be rude... I don't care about it.
It doesn't trump or remove my experience, expertise or qualifications... Which... You don't know what they are, so making this self-promoting paragraph entirely redundant.
Either way... This line of thinking is treading on the grounds of multiple logical fallacies.
| alexxonne said: 4) I was being humble with you, because I don't like to use AMD APUs. You can not judge everything in life based only on your self experiences; if something that makes you a naive person, something I highly doubt. You understood right away what I meant when I said VRAM, whether it was dedicated or shared ram, is still applied the context of my argument. Yet you decided to twist the argument to impose yourself with a deviated criteria. |
False.
| alexxonne said: APUs are just embedded processors within the same die, and the concept doesn't apply solely to AMD; Intel and Qualcomm also do this. But to answer you directly, all AMD APUs can have dedicated video memory if the target product requires it, just like with everything else. Sharing the memory is just cheaper, and by design is the default option for building APUs boards, but sometimes an alternative is needed The are some brands like Intel, Acer, Zotac, Asus, etc that offer a wide range of products (APU style) with dedicated video memory modules for specific consumer needs. |
"APU's" is an AMD marketing slogan... Which represents AMD's inclusion of GPU and CPU on the same die.
And the only APU's that can have dedicated memory are the APU's with the memory controllers to support such functionality, AMD generally doesn't spend the extra transistors on memory controllers for their APU's that will not get used, hence why we don't see APU's with dedicated VRAM.
You will need to provide a citation of those systems with an AMD APU with dedicated graphics memory.
| alexxonne said: Usually overclocking is limited in the bios. YES including those boards and cpus with unlocked potential. No matter how much you increase frequencies, the BIOS will not let you exceed some parameters and voltage, it can even default those values without letting you know if it finds instability. Whenever you computer restarts, crashes or shuts down, is a designed behavior from the Bios. If the bios lets you tweak something, then a tolerance level was already calculated. This is why sometimes you have to update your Bios, to have a better support and stability from new CPU or GPU units, etc. Most of the time with same model processors will have multiple configuration sets based on the code of manufacturing, so behavior and performance outcome will vary even from a same model. If your system was reliable for years it was because it was only a marginal tweak, one already calculated and compensated in the BIOS internal code settings. But those changes will bite you back...sooner or later, depending on the quality of your build. The only exception for this is ram overclocking, as ram modules do not have an ID tag for custom function sets based on the stick model and brand. Instead they use timings for compatibility, but if you mess with those, well unexpected behavior can occur, maybe a a random crash or a full corrupted hard drive. A very high overclocking on a ram stick would crack it, and I have seen it, when using nitrogen as cooling solution, it pops like pop corn out of the motherboard. |
You can modify a BIOS.
Plenty of motherboards will allow you to take everything to the utmost extreme... CPU's tend to have a clock-frequency curve and a hard wall until you start to throw extreme cooling like Nitrogen at the problem.
Then you can exceed the voltage tolerances of motherboard designs.
RAM can have profiles.
I have had overclocks of 100% on some rigs, 24/7, years at a time, no issues... Electromigration hasn't set in. - In-fact my 3930K system will turbo up to 5Ghz without much drama. (Silicon lottery.)
