I purchased some samsung "wonder" ram (the ULV 30NM slim ddr3 modules that everyone is price gouging) and one module is totally crap. It straight up won't post on my Asus P8Z77-I Deluxe and it got about 38 memtest errors when running it on my Gigabyte Z68MA-D2HB3.
I called up samsung and since this ram has a lifetime warranty they are willing to replace it. They couldn't answer clearly whether it would be replaced with the exact same module or not, as it's no longer manufactured, and they said it could take anywhere between a few days or 3 weeks depending on inventory.
has anyone had any experiences with samsung memory RMA?
No, but it's an interesting question you pose, and here is the reason I think so.
While I "missed out" on the fabled no-frills overclockable Samsung RAM modules, I finally made the jump from "accelerated HDD" to straight-up SSD boot drive with Samsung's RAPID feature. I probably had the drive for three months before I finally made this swing -- wanting to be sure that my HDD Windows configuration was tip-top.
So before I took the plunge, I tried several times -- SEVERAL! -- to use Samsung's tech-support e-mail for some questions I had. I set up a Samsung account, did everything you would do to assure support-ticket submission and obtain e-mail response. When you click the button to submit your question, nothing happens. You just . . . can't . . . get . . . through to them. Nothing wrong with my web-configuration. Nothing wrong with anything.
I've been able to submit questions to Intel, ASUS, WD and several other HW and SW companies -- some not requiring an "account." It often appears that some companies try to insulate themselves from tech-support queries and make support-ticket submission a bit convoluted. In this perspective, one suspects Samsung is exceptional by making ticket submission outright impossible.
Somebody could set me straight if I "missed something" on the Samsung web-pages, but I think not. I tried to successfully submit a tech-support question too many times, and I poked around through their web-pages until I was blue in the face.
ON THE OTHER HAND, their caveats about your RAM RMA seem little different from the disclaimers and caveats that informed RMAs of RAM I'd made with other companies and makes. Crucial was one example, and there were likely reasons for that, since Crucial at that time had been overwhelmed by more RMAs than they might have anticipated with the sort of specs they published for the modules.
I give my best acknowledgement to G.SKILL for their tech-support, and an ability to replace modules with the same model and spec. Between your experience and mine, with any other brand -- all bets are off other than the reasonable expectation they will honor the "lifetime" warranty in some way, even if it doesn't satisfy.
