Memory testing for DDR4 / Haswell-E

[Mr Alpha]

So I am having some transient issues which I suspect is RAM related. What are the good go-to RAM testing tools for DDDR4 on Hawsell-E nowadays?

AIDA64 memory + cache stability tests ( best to pick both as you test memory and cache/memory controller at the same time )
Prime95 blend
XTU memory stability test
HCI memtest ( runned for full memory coverage at as many instances as you have CPU threads or at least cores )
memtest86+ ( multithreaded if you make it run as it's not always working and then better is HCI )
