Thank you very much. My problem has been resolved
Both
Yes
thanks. downgrade firmware Controller and Machine both?
Yes
Dude,
You have the new low power firmware installed.
That's why your hash rate is lower than stock A851.

that psu is no good it does not have enough power it is 1600 watts not 1800 watts.
set the miner to 0 not +1
show me a 2 hour hash rate
Tell us your native language.

I suspect that there might be a language barrier in this case
The Avalons report what your PSU is feeding them. Check Status > CGMiner API log. Near the top you will see:
The line Vi tells you what the PSU is feeding to each of the PMU's (Power Management Units) and PG is a generic Power quality value.
In my above example the PSU is feeding 12.03, 12.03, 12.12 and 12.12v to each of the PMU's and PG is the typical value of 15 (very good). If PG goes below 13 or so you will have problems with boards dropping out.

I looked at your screen shots they are for 5 minutes
and you overclocked to +1
so try showing a 1 hour screenshot not a 5 minute screen shot
and try it with no over clock
5 minutes is pretty much worthless for telling true hash rate.
and the 851 is power mad hungry on over clock
so the 1800 watt psu could be too weak do no over clock please.

And also post in the Avalon Support thread https://bitcointalksearch.org/topic/troubleshooting-and-repair-guide-for-avalonminer-models-721-741-761-821-841-3224256 along with reading that thread - at least the 1st post - as you may find your answer already there.
Oh, and when posting the API log please be sure to use the CODE tag (looks like # ) so the log does not become a wall of text....

You might want to post the Cgminer API log for starters!!
