techpowerup上的说法:1 厂商选用了一些“不那么能打”的核心并且官超OC 2 重要的电容缩水。

this meant that their actual testing and QA for produced RTX 3080 graphics cards was mostly limited to power on and voltage stability testing, other than actual gaming/graphics workload testing, which might have allowed for some less-than-stellar chip samples to be employed on some of the companies' OC products (which, with higher operating frequencies and consequent broadband frequency mixtures, hit the apparent 2 GHz frequency wall that produces the crash to desktop).
It's likely that the crash to desktop problems are related to both these issues - and this would also justify why some cards cease crashing when underclocked by 50-100 MHz, since at lower frequencies (and this will generally lead boost frequencies to stay below the 2 GHz mark) there is lesser broadband frequency mixture happening, which means POSCAP solutions can do their job - even if just barely.
崩溃到桌面很可能与这两个问题有关--这也可以证明为什么有些卡在低频50-100MHz时不再崩溃,因为在较低的频率下,发生的宽带频率混合较少,这意味着POSCAP方案可以发挥其作用--即使只是勉强。
