DDR3 SO-DIMM in 2017 part2

After running into the row-hammer issue with new DDR3 SO-DIMMS for my notebook, ive tested all my used computers ram. I think i had tested at least some of it previously. These where DDR4 Micron Technology 16ATF1G64AZ-2G1A1 and CML16GX3M4A1600C9 from corsair. Both showed no issues on multiple passes of the row hammer test. Ive also now obtained new SO-DIMMS for my notebook, M471B1G73EB0-YK0 from Samsung and HMT41GS6AFR8A-PB from SK Hynix. Both as well have shown 0 issues in the row hammer test on multiple passes. So it seems that the issue is not as widespread in 2017-11 as looking at a set of 2 modules would have suggested. Ill return the faulty modules …
Iam a bit curious who the manufacturer of the chips on the faulty modules is but there are stickers over them and as i want to return them i dont want to peel these off. And in dmidecode they are just listed as “Corsair”. I guess if Corsair wants to make it hard to find out who made them, they will have to take the blame here.
