Thank you Daniel for this article.
I have Dell XPS 15 (9570) with CPU i7-8750H. Original RAM is 16GB.
I had a call with Dell support and they told me that maximum for my model is 32 GB. But I needed more (VMs and Docker, etc). They also told me that new memory must be 2666MHz but nothing about latency limitations.
Your article confirm to me that there are no additional limitation of memory by Dell (but it is common in laptops from others producers). My CPU support 64 GB. My theory was that in time when dell release this lapton there were no so big memory modules thus they could not test it and it probably does not make sense now to go back and verify it on "for old models". Thank you for that point to lantency.
Previously I tried "HyperX SO-DIMM 64GB KIT DDR4 2666MHz CL16 Impact" which is dual kit (2x 32 GB) but laptop did not start (just flashing orange). The most probably it is because of the lattency which is mentioned in the article.
Now I bought 2 modules of "Crucial 32GB DDR4 2666 CL19 SO-DIMM". It is not dual kit. Just bought 2 the same memory modules. They WORKS WELL. No issues. Proof by The Memory Diagnostics Tool.
Thank you Daniel once more.
