Pool is giving me less then im hashing! help!!!! ANTMINER

[assjiggler]

im runinng an antminer and on the output im getting around 2Gh/s for about 3 hours now but within my pool its telling me im getting 1.3 gh/s what gives?
it only happens when i overclock my miner.  right now im using the frequency 0981  to get 2gh/s  its default is 0781 at 1.6gh/s   but it works when i keep it at 0881 at 1.8 .
im so confused like if its tellin  me im getting 2gh/s why isnt my pool?

also im getting an error when i try to over clock it to 2.2gh/s with 0A81 it just never finds anything or connects

any help would be gladly appreciated thank u

Chances are HW errors are lowering your reported hashrate to the pool.  If you don't know how to calculate HW Errors post a screenshot here.

Mist likely Hardware Error are lowering your effective hashrate. Sometimes quicker is not more effective. It probably is better to lower the clock but have less errors and thus a more regular and truer figure on the pool.
