Because u are compareing two different memory architectures. GDDR5x isnt GDDR5 and vice versa. My results are slower because I used default clocks. I dont want burn my house on this Asus Dragon 
When I put MEM + 1000 will get generation time 10s and hashrate about 26.5Mh/s - Epoch 383. But still I will not get results like 33Mh/s with enabled mem tweak. You can nicelly see it on Nicehash graphs when someone order ETC hashrate how it all drops since it have different DAG size like ETH currently.

So, what OS are you using? I'm trying to find a pattern here because I'm hearing other ETH miners have the same issue.
