There are of course different kind of hardware errors and what appears to be bad memory might be due to some cells being defect or some less-than-perfect bus signals (which then should affect many addresses). In my (limited, perhaps dated) experience (I used it on maybe a few dozen computers), stressapptest (even using the default plain memory test), is much more efficient in finding hardware issues than memtest86+. If stressapptest doesn't find a problem in 30s, memtest86+ won't find any in 24h. I haven't bothered with memtest86+ in years anymore.
EDIT: only ever used the free memtest86+ tool, I have no experience with PassMark's MemTest86.

All PC builders have this experience - on a certain motherboard model, some DIMMs work, some doesn't, but they are all off-the-shelf parts that follow JEDEC standards. Often there are minor variations in electrical characteristics from DIMMs to DIMMs. If the signal integrity on the motherboard is marginal, there will be mysterious problems.
