Can memory be faulty from factory that often ?

[AdamCZE]

Hi there,

I just want to know how often or what's the probability, that a ram memory can be bad from factory - and I heard that before from other people, that ram may be problematic from default and not work even if it is compatible etc.
I just experienced it with my newest build - I have bought trident z series from G.Skill - RAM 2x8GB DDR4 3200 16-18-18-38, TridentZ Red Series factory number F4-3200C16D-16GTZB

First I've inserted both sticks and my mobo (msi z270 gaming m5) had error code 55 (no memory installed). So I removed one stick and restarted the system - it worked fine, loaded bios.
Thereafter I've removed the working stick and replaced it with the second to verify thats the bad one and it caused the error 55 and was restarting the pc over and over.

Now Iam sending the sticks back to the shop to claim and Iam worried, that the same situation can happen again.
Was that just a coincidence or is that a common thing with the ram memory ?

Looking forward for more information

Thanks

It's completely possible for faulty products to be shipped to you.
Just return the stick that doesn't work and ask for a new one, or get a new set.

If memory was purchased as a set, then the entire set must be returned to get a replacement from the manufacturer. You can't return 1 stick from a 4 stick set. They want all 4 returned, since that was what was sold.

Sure, I sent them both as a set, that must have been a coincidence then...
