Does all DDR4 have temp sensors? Or just some brands / DIMMs?

I noticed that in my Ryzen 5 rigs, my Avexir DDR4 seems to have temp sensors readable by HWMonitor, as does my Team Dark DDR4 in this rig. But I recently upgraded a couple of a Ryzen rigs, to Team Vulcan DDR4-3000, and now they don't seem to have temp readings any more.

Trying to figure out why.

So far, all I've noticed is that my Samsung B-die memory has this ability. Anything else, (including my Team Dark) does not do this or show in Corsair Link.

Running G.Skill Trident Z 3200, I have sensors as well. The cheap crucial stuff in my two mining rigs doesn't have them and neither does the geil 32GB kit in my other x99 rig.
