So i've done (almost)everything you told me and... memtest has found some errors. However, I can't test ram modules one by one, because of the warranty.

If memtest shows errors, no further testing is needed. What is needed here is to determine that whether it is a RAM issue or motherboard issue. But for that, stick by stick memtest is necessary.

As you cannot do it, and it is within warranty, RMA the RAM. Let us know after getting the replacement, that how it is working.
