They only draw 620W so if you have a spare PSU lying around use that and it'll be very quiet.  The provided Innosilicon PSUs are very loud, the actual miner itself is quiet though.

Looks like there's a new firmware. Has anyone tried this?

thanks nice to see inside.

oh you're right. thanks, kind of invalidates test I was doing.

I noticed that if I have  "T1performance": true,  then the clock speeds I set don't seem to stick. Looking at the scrolled logs they seem to revert to 1250.

aah nice.

So I've set this a9 to

    "T1performance": true,
    "T1Pll1": "1300",
    "T1Pll2": "1300",
    "T1Pll3": "1300",
    "T1VID1": "170",
    "T1VID1": "170",
    "T1VID1": "170",
    "A1Fanspd": "20",
    "A1Fanmode": "0"

can't see anywhere where mentions clockspeeds... tried cgminer.devs() cgminer.devdetails()

This is from the pdf show PLL output clock frequencies and core voltages.

https://imgur.com/a/PGWiMhi

From their website "the A9 Zmaster has operation modes from low power to over clock high performance through adjustment of PLL output clock frequency and/or in combination with voltage adjustment - See more at: http://www.innosilicon.com/a9asic/index.html"

Also if you google "innosilicon a9 clock speed" there's a pdf that goes into more detail.

Yes I do see high hash rates in the first couple minutes. Might it be an artifact of it submitting successful hashes at a lower difficulty?
I also get the feeling that adjusting PLL speeds in cgminer.conf isn't properly taking effect or is somehow reverted.

It's puzzling. With gpu mining and Equihash increasing core clock speed didn't make nearly as much difference in memory clock speed.
At the same time the Bitmain Z9 seems easily amenable to overclock.

You have an error in your /etc/cgminer.conf  you're not closing the { } properly, if you paste the contents of that file can help find the exact error.

you want to use ssh or putty in Windows, connect to port 22. I haven't seen anyone have success increase speed though.

Hard to tell really. I haven't seen any noticable improvement in hash rates though... I am curious about the voltages for the first one it says a default of 8.


--T1VID1 <arg>      set voltage (1 ~ 255) (default:
--T1VID1 <arg>      set voltage (1 ~ 255) (default: 166)
--T1VID2 <arg>      set voltage (1 ~ 255) (default: 166)

Although it's hard to know how specific to the device those voltages. I can't see 166 set as voltage anywhere in my miner logs. Where are others seeing it?

Also not really sure why I'm seeing 20W lower power draw.

vim

Press i to enter insert mode then you can change things.
Then Esc-wq! to write the changes.

What is the default voltage? I'm wondering if 170 is undervolting the cards.

...oh 166, wonder if that's right.

..and power draw has dropped from 620W to 600W. I guess running fans faster and keeping things cooler...

Says here: http://www.awesomeminer.com/help/minerapi.aspx that on Innosilicon devices it's disabled, but there's a work around. I haven't looked at it.

I've been running at 1400 and 170. Seems stable and temps are at 50C with fan at 30%. Can't say hash rates are much improved yet. Only been running for about 30 minutes so far.

I'd be careful adjusting voltages if it's anything similar to overclocking gpus. Perhaps just start with clockspeeds.
