Default [Q] custom rom for lifetab e10316?

Hi there,

In december 2013, last month, I bought a new tablet, it's a rather cheap one, 179 euro's. I thought I'd be good enough for me, but it freezes lots of times, since I use a torrent client on it. Then it's unusable.
I thought, maybe if I root it, put a other ROM on it, it might be faster and I could even try to overclock it.
I rooted it, all went fine, but I have no idea how to put a custom ROM on it and have no idea if there are any available.
Could someone help me with this? I'm rather noob to these things.

Thanks in advance!
