Question, please advice?

I am running Phoenixminer (lastest version), I had reported 165/2/64 shares however no ones of the gpus reported incorrect shares, only the phoenixminer summary and of course the hashrate at the pool is low, what could cause this? How do I troubleshoot this? is this is related with too much OC although the gpus are not reporting incorrect shares?

Thanks in advance for your advice

Edit: pool is ethermine.org         OC core 1220 mem 2140, I am using -robost 30 hashrate 30.5 gpus 580s 8g
