yes, you are right.
I tried out now 835mV and 250Mhz, running without errors, stable at ~62.5
I do not know how long, running in this configuration since yesterday 3:24pm. I do not notice thermal problems, air from the fan is not hot, even not warm and the psu is just warm.
Let's wait and see.
Other question:
Somebody remarked that in this thread are recommendations ot Atx-type psu to replace the U3 one.
Can somebody repeat that ?
Couldn't just find it on the 30 pages ))))))

After about half an hour, hashrate is declining to 50

Seems not helping in improving hashrate ?
Any tipps or hints ?

Please set the miner voltage to 0830, frequency to 0982 to try. Notice: please pop up and pop in the USB cable, make sure you restart the miner before change the settings. And suggest that point the U3 to the pools like Antpool, f2pool or ghash and so on.
Any place where I can by 1 or 2 of these units intead of MOQ 20 as per BitMain's website?
I still have not seen an answer as to what happened to the five pack of these.
I would be interested in a 5 pack to play around with...
You could set up a regional group buy for packs of 5 if you're not interested in buying from resellers.
Wow, is that a non-answer? Sure was! We are all over the world. We cannot set up "regional" groups to buy 20. Come on. Answer the question. Why did Bitmain remove the five pack from the website? Simple question. Simple answer please. Not a Dogie non-answer, kind of rude special non-answer.
Hi, Jackbox,
An email has sent to you, please check.
What is the price of 5 with UPS shipping to Thailand?

You can improve performance by cleaning the over-application of heatsink compound between the heatsink and the processors. This will keep the units from going ZOMBIE but you will still need to reset them every few days.
Also, the Bitmain CGMiner does not (as I recall) support non-Bitmain devices, so if you are trying to run additional miners at the same time, forget it.

What do you think the usage of Bitmain-cgminer will improve ?
Better hashrate ? Improved stability ?

Its a different development path, neither is necessarily an improvement over the other.
AMU0: invalid nonce - HW error. What does this mean

Both of these could be PSU related.

It would be interesting to find out what the differences are between the bitmain-flavour cgminer driver for the U3 and the official cgminer driver.
I've never had any luck using the 'official, bitmain' version of cgminer but am getting a good hashrate (most of the time) with the Official non-bitmain CGMiner.
*However* My U3 just dropped out after about 6 hours last night despite being powered through the (750Watt) ATX supply.. had to remove both Power and USB before it would play again.
Waiting for that to happen again to try and diagnose further.

Tried the latest Bitmain version, provided from Bitmain_Kiddy:
Some questions:
The AU3 is now recognized as "AMU"
With the parms provided in the autoexec.bat it hashes around 60 avg.
BUT: a lot, I mean a really lot of HW Errors
AMU0: invalid nonce - HW error
What does this mean
Probably I should change the parameters and go down with voltage and frequency ?
Have a look:

Opinions/help is very appreciated.
Probably these HW Errors are normal, but the 4.9.0 does not show them as a message and just counting them in the status bar ?

Hi,
thanks for your support, btmain_kiddy
What do you think the usage of Bitmain-cgminer will improve ?
Better hashrate ? Improved stability ?
And what kind of attempts are meant by cgminer ?
Is my impression rightm, that when this counter reached '4' the au3 is quitting ?
Does this version support the - usb parm of the 4.9.0 version (I have one cgminerinstance for every usbport used running) ?

Yes, the chinese crap psu is probably one reason.
But do this numbers mean ? 0:AU3:0, 1:AU3:1 ...
It's a counter, beginning at 0, and then going up to 4 (in my case). When it's reached 4, the unit is hanging up.
Is it a temperature thing ?

The counter means the attempted times.
Have a look, what my cgminer shows.
I am talking about the status bar.
