Now no, the server is dead but usually yeah, I get crazy speeds of 200GH+ without overclocking.
Plus the merged mining (even tho they don't worth much) is still something extra

Ghash is not a good pool to mine on. Yes they charge 0% fee to make miners to join thinking they are getting a good deal.
Initially they said they charged 0% fee and mined for fun, but in actual fact they kept the merged mining rewards.
Ghash is unstable, it provides much down time
servers changed without warning creating more down time
despite your 0% fee, they don't pay for orphans which generally is above 2% per week ,Orphans for ghash last week = 2.83%
Do the network and yourself a favor and mine else where
