Hmm..... mine should finally arrive today. But it looks like I'll have to instruct someone to hook it up if I want it up and running asap.
Someone tell me, the thing has a standard IP adress 1st time you boot it up ? In the 192.168.x.x range?

Yes that is it exactly. Not aluminium though, steel. And they have the power consumption right too - 360w
I wonder whether the power consumption will go down with a better PSU.
It seems the standard PSU runs at 100% of it's capacity, that's not very good for efficiency.
It should. we have asked the manufacturer to look into replacing current PSU with better one.

1280Mh/s gives me >6% HW errors. I don't know if there is not enough voltage getting through or whether the heat starts to become a problem. I can live with 0.5% dead cores
yeah, we notcied that as well, 1280 is not always the best for every board. you want to manually adjust the frequency of each board and tune it for the best frequency.

Yes, I've seen your latest mods. I've put them in my version of Scripta. My A2 however has some dead cores, dropping my hashrate by 160KH/s on that module. Another fault to add to my list.
btw,lastest scripta also have updated frequency to 1280 . so if you want to change to that, it will allow a better hashrate.

OK, seems you are pretty technical . the cores in the miners are random. they don't always come as full functioning cores.

If you SSH into the raspberry you can edit a file called /var/www/run.sh.
It has --A1Pll1 1000 --A1Pll2 1000 --A1Pll3 1000 --A1Pll4 1000 --A1Pll5 1000 --A1Pll6 1000 in it, just change the frequency to 1280
Obviously don't then change anything in the web interface. You can of course edit index.php if you want to be able to choose the frequencies.

We are working on the minereu version of the scripta to support the frequency tuning. meanwhile, you can check core temperature with minereu version of scripta.
check it out here: we already setup the default mining frequency @ 1280

Well I've had my A2 for abut 36 hours now. It's been hashing nicely with only a handful of hardware errors at 1200Mhz. Power consumption is much higher than that stated on the MinerEU site. The site states about 250W, but in reality I'm seeing about 370W at 1200Mhz.
Looking inside the case and there is a 30A regulated 12V supply. Not the Gamezone 80+ type shown in the pictures. The power supply socket is also on the front with the other sockets. The case is also silver not black. The PSU in the case is connected to the ATX socket on the control board via a voltage converter.

Hashing OK. According to Raspberry Pi 29MHs, on the pool around 26MHs (1200MHz). Is it possible to upgrade to 1280MHz ? (I have similar miner, but blade version from lightningasic and it works on 1280MHz - 31MH according to Raspberry Pi, 29MHs on the pool)
Silver (not black) case with some scratches and one with some more empty holes for screews..., cheap PSU S360-12V, not standard 80+ Gold Gamezone ATX as described.
Noisy, very high speed fan.
Can you link me a downloadable Pi image of the one running 1280 ?
And I guess you ca just copy th eSD to the other one and have that running same speed.

And unless magnets have started sticking to aluminium, the case is made of steel
I see many small Chinese factories producing A2 Mini's on AliBaba and some of them are using blank Aluminium cases.
We have probably something like this:

Anyway, tomorrow I can see for myself what it looks like.

Powdercoated I think, not anodised

Is the case anodized or is it blank aluminum?

Should be room for a decent PSU, but some cutting of the case may be required
Update for you guys: we have feed your comments regarding the PSU back to manufacture. we will udpate you with the lastest
Thank you MinerEU!
