Should I change my channel name, and if so, do you guys have any suggestions?

My channel name right now is currently DM Gaming HD, which I think is kind of generic sounding and a bit too long, as well as just a bad name in general. However, I have had this name for about a year now, and other YouTubers have shouted me out under this name. Do you think it's worth changing my name, and do you have any ideas? An ideal name for me would be short and have no more than 6 letters. It doesn't have to be related to my content, I would just like a name that sounds good.

Also here is a link to my channel if anyone finds it useful: https://www.youtube.com/channel/UCyzNQNrLi981lWOmypTGrDQ/featured
