Hey, I had a similar issue with my Corsair Vengeance RGB ram (not pro) a while ago too. (Constant bsod and memtest issues) I opened up a report thread and after finding a receipt was able to RMA them. I shipped them in but that's where the issues began. They never properly logged my ram into their system, and after talking to the customer support for about a week, (I was getting about one response per two days) they finally figured out that the warehouse workers had messed up the logging and didn't ever ship out the new ram. (Apparently a common occurrence) After finally getting that fixed I asked for compensation for my time by doing expedited shipping. It then arrived in two days from Taiwan, (I live in DC so that's crazy fast) and all was good after that. I recommend you be persistent with the responses to the thread, and if it takes especially long or there are issues getting it through, ask for some compensation of some kind (merch or as in my case, speedy shipping). They are usually pretty slow though.
