This actually leads me to a question... on older systems (pre-Haswell Intel, or AMD pre-Ryzen), these are absolutely fine, even with, say, a more modern video card?
I thought I'd read something about them not handling power demand changes well on modern systems, but if that's false, then, ugh, know I've erroneously passed that incorrect info on.
I am unaware of any information showing conclusively that there is any kind of problem running these units with pre-Haswell Intel platforms OR with post-Haswell platforms so long as the C6 and C7 low power states are disabled, or with ANY AMD platform, since none of the AMD platforms have a similar implementation to what causes that problem on the Intel platforms. If there is, I've either not seen it or I've seen it and it wasn't substantiated so I forgot about it.
I'm pretty sure if there WAS a problem, we'd have seen a MUCH bigger and continuing stink about it than anything that we've seen in the past when the whole Haswell low power state thing became a popular subject of discussion there for a while. In fact, I thought I'd read something recently saying that the problem was actually somewhat overblown ANYHOW, even on the newer Intel platforms, but that playing it safe was a good idea anyway because of the obviously inherent flaws in those group regulated platforms including lacking in efficiency, lacking in protections and lacking in some other features found on newer platform designs and implementations.
But "work"? I've seen nothing that suggests there is a fundamental reason why they can't be used with ANY platform, at all, so long as you take the appropriate steps to ensure that C6/C7 are avoided if it is a platform that will try to use it.
If there is compelling evidence saying these shouldn't be used with modern platforms for OTHER concerns, I'd sure like to see it.
