Title: Antminer S2 Hashing problem just 600-700 GH/s Post by: GeeCkO on August 06, 2014, 05:08:30 AM Hi,
My antminer S2 have been restarted automatically, and then, it just work at 600 - 700 GH/s don't know why? I have upgraded the firmware but it still not working at it full hashing power. I have contacted bitmain just waiting their reply soon... But, does anyone know what can I do? or someone have a similar problem? Thanks in advance.

Where do you ovserve such a value? At S2's LCD? At your mining pool side? In miner's web-GUI? Automatic restarts indeed looks like a PSU issue.Remember that you need a PSU with single 12V bus if you decide to replace it (you better replace it...).

I hope this info helps some one else. Best, Title: Re: Antminer S2 Hashing problem just 600-700 GH/s Post by: defcon23 on August 07, 2014, 02:00:43 PM yo man ! ;D happy mining ! ;)
