Let's just say it's not IMpossible.
 
Memory modules and slots are keyed to fit only one way and of the correct type (DDR2, DDR3, DDR4) so it's pretty much foolproof.

You can remove the modules and check the slots for bent/broken pins if you suspect any may be damaged, and describe any problem you're experiencing.

I'm perplexed.
 
I'm a senior electronic technician specialized in computers with a college diploma. I have built an incredible amount of systems over the last 28 years.
 
I also omitted to indicate that the actual pins in a DIMM connector - Socket are tensioned with a bend to contact the memory module contact pads on the sides. The pins have no jagged edges or ways of hooking. You could put a screwdriver in the socket - connector the pins will bend back and come back to their initial position. There is to my knowledge no way that a user could bend pins by inserting the proper memory module and even the wrong one just won't fit and get close to the pins. In development and engineering the term used is electrician proof.
 
I bent 4 pins at the first insertion of a memory module it seems. The memory module was a bit difficult to insert and I pushed it in firmly like all the other ones that I inserted. EVGA support management claims: "DIMM slots are tested in the factory thus they cannot arrive damaged to you, along the manufacturing process each component is tested on a motherboard, including the PCIe slots, CPU socket, etc."
 
I specified that memory sockets - connectors are designed and engineered to be fool proof. Asked them to send me a demonstration video on how the impossible task of bending pins can be accomplished that was obviously not followed up. I also asked them to consult with electronic technicians an electronic engineers to back up their claim if they do not have the technical knowledge with also no follow up.
 
100% quality control and no part failures of mechanical components like memory socket connectors are inexistant. There is always a human error factor.
 
We are talking about a connector - socket that costs less than a dollar when purchased in bulk. The only alternative that was proposed was to replace the motherboard. My warranty claim was refused as they claim without any doubt that its user damage.
 
To my perspective EVGA will find any unsubstantiated reason to back out of a warranty claim.
