Sudden Drop in ETH Hashrate

[TGJ]

I have been mining ETH with a 6 card (RX 580 / RX 570 4 GB) rig using Pheonix miner on SimpleMining, I have been averaging about 30 MH/s for each card. I noticed on December 11th, the rashrate dropped to about 22 MH/s so I rebooted the rig.  After the reboot, the average is only about 3 MH/s.  I have tried adjusting the overclock settings and nothing seems to work.  Any ideas what happened and how I can get back to a decent hashrate?

dag memory size, you need to update pm to 5.3b fix.

That's what I am using.

Well it should work even if the dag is the problem, pm has the zombie mode too, it must be your command line settings.

The best miner at the moment avoiding the ETH drop is lolMiner, other the drop down is much bigger...
You only need to add:
 --4g-alloc-size 4072 in extra parameters

Well... but if it work try 4074, 4076 and 4078... until it stops - for maxing out epoch 382+ performance, later zombie mode will start slowly...

Switched to lolminer and you are right, hashrate back to 30 MH/s. Thanks!

Thanks to you... enjoy mining... not for long time but at least with lolMiner some extra time :-)
