The optimal method involves running stress tests under heavy load and monitoring performance over time.

Memtest86 offers quick results but may not detect issues from overclocking. It works well for basic checks at default configurations. The methods used might be outdated and less effective against modern hardware demands. Other tools like HCI Memtest, Karhu, Testmem5, or online stress tests can identify problems that Memtest86 misses. Therefore, you're unlikely to get identical results unless something is severely damaged.
I'm choosing Karhu since it's user-friendly and runs in just 2.5 hours for 16GB. However, it comes with a cost. Some recommend running multiple stress tests or even adding Linpack to check for performance variations and potential issues. Personally, I prefer whichever method you like, but I won't use Memtest86.
It's important to note that bit-flips can stem from both defective silicon and mismatched timings or voltages. Tools like Memtest86 excel at pinpointing RAM issues in targeted areas, leading to consistent errors at certain addresses. Yet, faulty timings or voltage levels tend to trigger random failures across the entire memory space. The challenge lies in the fact that each detected error overlooks many others happening simultaneously, since real-time verification can't capture every issue precisely. This approach is akin to spotting only a small part of a larger problem—finding one error reveals far more hidden issues that remain undetected.
