Bought 2 kits of RAM a few months back along with a few other items. Built a system from it all and all was going fine. Errors started happening and after a few tests and removing 1 kit of RAM everything was working fine again. Tested the problematic kit in my othe 2 builds and the same happened, errors, crashes and freezes. Clearly this kit of RAM is faulty, sent them an email, they offered an RMA, and less than 24 hours after receiving the kit back, theyve deemed them faultless and are sending them back. They have clearly got a botched RMA process because this RAM kit was failing while doing anything on the system they were installed in, seems like they install them, boot up the system and deem them perfect because they can boot up windows. Ive told them that i'll be recording myself installing the kit and proving the errors happen then making an official complaint until I get my money back. I would have been happy with a replacement, but not I want my money back. Never again am I choosing this company.
