Check the dashboard, does it show your shares?
Many people think that hashrate matters...it does but only in the sense that you are getting shares.
The amount of shares you are getting is what matters.
I have a few nvidia rigs and if my intensity is set incorrectly it will sometimes show great hashing but won't find any shares...also sometimes if you add your worker number after your username (xtl add) example: -u sedif83hfhsdhfo83hrlwlhfhihs.rig1, sometimes this will cause confusion with a pool.
It takes 3 hours for a block to mature...if you are not getting anything in the pending by that time...check your hashrate and shares against the dashboard or try a different pool.
In my instance, a lack of shares was not the issue - other than the one invalid share that was submitted, there was nothing occurring that showed anything out of the ordinary on my end. The end result is that the balances were paid and sent to my wallet, but this occurred hours after the blocks had matured.
