1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Innosilicon releases A9 Zmaster 50ksol/s Equihash miner at 620W on: July 27, 2018, 01:42:01 PM
Guys I just bought one, and started to mine.

I saw around 40-42 K/SOLS all the time, not reaching 50. (I currently use nanopool)

I changed the performance mode still the same. Current Firmware is b29+_20180706_032013
6th of July 2018 03:20 AM , I haven't updated to new one yet.

First and second cards are ok at rate of 14-15 Kslols but third one stuck at 10Klsos.

Do you have any idea ? Thanks in advance.

Silicon lottery.  Not much that you're able to do about that. 

I can tell you what hasn't worked.
I have a bad unit that does 12ksol/8ksol/7ksols.

I have:
Used different firmwares
Set fans 100%
Changed controller board
Changed Power supply
Inspected board for visual issues -none
Applied thermal paste
Overclocked

Overclocking has produced no noticeable gains. Under clocking works but does not reduce HW errors (only some firmware shows this). Tried 1250-1350mhz/VID 155-180 for overclock.

Gunna compare per chip voltages from reported to reality and between my good and bad unit this weekend.
Also trying to figure out how/if I can reduce the SPI speed.

Kinda think it's bad chips but innosilicon vaguely said they didn't think so. I'll post more if I find anything.

Sorry to hear, you suffered a lot, so in deed there is not much to complain comparing to yours situation.

Hi Guys! I wish all profitable mining...

I recently had serious problems after windows update. Rigs started to crash.
One of the sata connectors catch fire and melted, two graphics cards dead no power (not because of melted sata it was another card and still working)

And right now I am having GPU 0 hash rate 0 issue, it happens identically 2 of my rigs. It happens whenever I remote connect via teamviewer then I need to restart the rig, and I need to be there physically to do that(gotta switch the display otherwise it is not going to work) I do not have this problem before windows update and v.11 but I guess it has nothing to do with v.11, I downgraded v.10.6 and still happens.

Do you have any idea? thanks for your help in advance...
