To keep this short. Y-Cruncher is a DRAM benchmark http://www.numberworld.org/y-cruncher/ to compute Pi. I have found that when the system memory or CPU OC is not stable, the test will fail either by BSOD / Instant Restart or a test failure message saying the cache is too large (or something of that nature).
There have been a number of instances where the memory will "pass" TestMem5 or Karhu stress (1000%+), but fail the benchmark. Usually the remedy is to tweak the timings, raise the CPU memory related voltages or occasionally just DRAM voltage.
Where do you draw the line? For example, DDR5-6400 can boot into windows for AMD, but only one motherboard so far has passed y-cruncher 2.5B for me. DDR5-8000 works on a number of SK Hynix-A die for Intel, yet only passes y-cruncher with a cold boot (or much loser secondary timings / tertiary when warmed up).
Do you believe passing Y-Cruncher 2.5B / 10B (32GB) / 64GB) should be a requirement to consider it stable system memory?
