the crashes happen when it was this year on January. I used windows 8 on that time so I thought it could be my windows problem, so I updated to windows 10 but it still happens the same. For some reason, the crashes keep come and go. Even if I solved the problem, playing games without even 2 weeks it happens again. I also thought it could be my hardware problem, brought to shop and ask technician about it. Twice, there are no problem with my graphic card and other hardware. I've even tried formatting, but still couldn't last playing for 2 weeks. Tried reinstall driver, insert TdrDelay registry, uninstall google and others. I just couldn't figure anymore, maybe you guys have any ideas what's wrong with it? By the way, is there any difference with R9 M275 and M275x? Does it related to RAM as well?
