I just thought about that 
And could help me with my first card (is much hotter than 2nd and 3rd)
How to make it max temp. to about 80*C and other f.e. about 75*C ?
-tt should be turned on if I want to use -ttdcr , isn't it?
or I mess something and I can make it in AMD overdrive?

You can use default -tt 1, so drivers will manage temps, but -ttdcr still will work.


Have to wait when AMD releases ADL 10:

Atiwinflash goes wrong more often than not in my experience better to flash from bootable dos usb.

i was able to flash my sapphire r9 390 with the usb dos atiflash but it cant see my sapphire r9 380. too much of a pain at the moment to move it to a windows system to flash with the windows version. those 2 cards are on ubuntu 15.10.

lotta power savings via flashing cards to undervolt them when they will be in *nix based rigs so ill do it soon.

I can not mine ether and sia. Miner says invalid http response, incorrect data size?

This is my bat file:

EthDcrMiner64.exe -epool eu1.nanopool.org:9999 -ewal etheraddress -epsw x -eworker workername -dpool http://sia-eu1.nanopool.org:9980/miner1/6cefa5777a7b68d942aff47050b3d86ff743dcf2b1408e10fb7d5892bb66bdb477033a29be21 -dcoin sia

No, 9980 is for SC, parameter -epool is for Ethereum, and port 9999 is correct for stratum. Perhaps you should specify the protocol like in the examples like stratum+tcp://eu1.nanopool.org:9999

Edit: just an idea, don't mine Eth on nanopool myself.
Edit2: should follow my own advice - see samples on page 1:

Running 8 Pieces of R9 380s 4GB with eth+sia
- Getting 300MH per card for sia.
- From what I see, I cant change anything with the voltages or clocks (downvolt/clock) without sacrificing mining performance on both sia and eth.
- Cards are running approximately 10C hotter.
- Mining on Nanopool - Don't see any payouts so far.

Questions, what pools are you guys using?

How long does it take the SIA wallet to update?  There is no count like other wallets.  Been up for 24 hours and it has done nothing.

It shows 8 peers and a Block Height: 43948

From examples:

ethpool, ethermine  (and Siacoin solo):
   EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0xD69af2A796A737A103F12d2f0BCC563a13900E6F.YourWorkerName -epsw x -dpool http://localhost:9980/miner/header -dcoin sia

 ethpool, ethermine  (and Siacoin pool):
   EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0xD69af2A796A737A103F12d2f0BCC563a13900E6F.YourWorkerName -epsw x -dpool http://sia-eu1.nanopool.org:9980/miner/header?address=3be0304dee313515cf401b8593a0c1df905ed13f0adaee89a8d7337d2ba8209e5ca9f297bbc2 -dcoin sia

Never mind, it's still counting.
