Antminer S2 Hashing problem just 600-700 GH/s

[GeeCkO]

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.

Have you tried a different pool? Any dead chips or boards not showing up?

that's not necessary a faulty chip.. first, have a look to the psu ..

Ok, will try with a 1200W PSU, then I will post the result with it.

Thank you defcon23

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...).

It was the PSU as you said,  I have change it with a Corsair RM1000 and the S2 is working now, I will upgrade it with a AX1200i as the RM1000 was connected in 2 S3's.

I hope this info helps some one else.

Best,
