The original sticks probably would fail under conditions that you are hitting commonly when running normally, whilst the new sticks may only fail under a particular access pattern that you are not happening to hit.

Does this mean that why no problem with the new sticks was that the machine was not used exactly the same way as when the old sticks were used?

How you use your machine is between the two points so in general use you see failures with the old but not with the new. Memtest is stressing the memory to the limit so it finds all the failures.

You appear to indicate that the extent of the defect of the new sticks is smaller so that I will eventually see the same problem. Is this correct?

I would think these hardware conditions can be considered the same since I only replaced the old sticks with the new sticks and everything else was unchanged.
