Sigh.. DDR4 temperature question

Greetings fellow PC enthusiasts... my system specs are listed.

I have noticed that according to HWiNFO my hottest DIMM (I assume this is the one right next to the I/O shroud) will get to the mid-50s degrees C while gaming or prolonged stress testing. Despite running XMP-3200 on an old, unsupported platform and a low VCCIO/ SA voltage (1.05v and 1.10v respectively) I have had zero stability issues.

So far, I have heard that Samsung B-Die memory hates temperatures above 40C whilst Micron memory isn't nearly as sensitive, even exceeding 60C at more aggresssive speed and timings and still being stable.

Can anyone help me clarify this is still a good temperature? No errors or strange behaviour is obviously a good sign but I prefer not to be living on the edge.

Thanks :)

Going over a certain temperature threshold, the actual value varies from one kit to another, can lead to stability issues with B-Die on very tight timings and extreme settings that require a high Vdimm. However XMP-3200 is very far from tight and extreme, so I wouldn't expect any issues with that.
