Yes i did never go higher then 387.5 Mhz because i think its not really worth going higher
The one constant showing the xxxx on all cores does seem to make 180 Gh as written by the makers, and so far is not going much faster if i clock it at 387.5 however it seems to be a little faster on 375 Mhz which is in my view still much below the actual speed these antminers can do.
So for some it might be worth the risk goin beyond the 400 Mhz i think the difference will not be worth the small increase in speed gained.
I rather stay well withing normal operations below the 400 Mhz so the miners stay alive for a longer period.
Its just weird that the x's appeared since the box has been placed, but again it does keep running steady around 180 Gh.
Am just wondering if it might be something with the cooling or something, if i let the fan run at full speed the noise is enormous
And even then after some hours mining the x's appear and stay. So i am not sure if it is nothing to worry about or that there is something wrong with this one for the long run.
I've found a sweet-spot on the damaged miner at 387.5 and it keeps the errors under 1%... can't go any higher without it it jumping over 6%. That one shows no X's and has been running at that speed for days now.The one constant showing the xxxx on all cores does seem to make 180 Gh as written by the makers, and so far is not going much faster if i clock it at 387.5 however it seems to be a little faster on 375 Mhz which is in my view still much below the actual speed these antminers can do.

The newer miner is running at 400Mhz and is very stable... the X's come and go and there doesn't seem to be a pattern, sometimes they go away without turning the miner off, so I think it's a software problem.
I agree on that setting because no matter what speed i set from 200 tot 387 i get to see the whole line keeps changing into XXXX
Hmm you might be right especially since i see no change in hash speeds but i sure would like one of the techs from bitmaintech to confirm or better yet look at this
Because the ultimate test with the fan running full speed showing 4000+ rpm does not change the X's appear after several hours.
So i am sure its not the cooling nor the power , my 1200 watt antec / 1600 watt lepa and 1000 watt nzxt are very capable of feeding 2 ants
While the 850watt corsair became extreme hot when running 2 ants the 3 above do not even get warm running 2 ants.
Everyone seems to be going a little overboard on cooling when it's clearly not the problem as you can get the chips to run at 30o with the stock fan alone, which you've proven has no effect on the X's and I've seen no improvement in hash rate when doing that either.
I'd say check your kernel log and if it says something along the lines of: [Memory: 28848k/32768k available] only 32Mb instead of [Memory: 61336k/65536k available] 64Mb, then you have the same problem as I do i.e. faulty controller board. I've been in contact with sushi as I bought from him and organized a (hefty) deposit to get a new controller board shipped and I have to send the damaged one back within 2 days of receiving the new one or I forfeit the deposit. It's Bitmain's policy, but I can just imagine the hassles they've had with people not returning items etc. and I can imagine Sushi is quite bogged down with all the traveling he seems to do, not to mention the CNY which seems to cause as much havoc as 1 inch of snow in London
Wait, I got that - Memory: 28848k/32768k available . The unit hashes on just fine at 400Mhz though...
