Hi together,

First of all, thanks for your help.
it is up and running now:-))).. After a really hard weak of troubleshooting, the new minig rig i working now, with 4 X RX470 Nitro+ 4GB..
What the hell.. Arizer damaged. 2 of 4 GPUs damaged, PSU trouble.. And many many more..
Now, i´m wondering how i can optimize the Hashrate.. But step by step. First thing. My Rig is lagging really hard, when mining over GPU Miner v9.7.
Is that normal, or is this something i can fix, with better settings? Sometimes, after hours, the rig just shut down.
Is there something i can do. I tried out tons of crimson drivers. Most of them doesn´t work for Win7 64 bit and don´t identify my cards. I only got V16.11.1 and 16.11.4 to work. When i run claymore now, with the following command i get 2450 h/s. This are about 610 h/s per card. Is that good, or bad. There are so many comments, with different hasrates.

NsGpuCNMiner -o stratum+tcp://xmr.pool.minergate.com:45560 -u paapolinho@gmx.de -p x -a 3 (i tried A 4 and A 3 also, without changes)

I also tried to flash the rom, but it doesn´t work. ROM can´t be deletes, was the error. Is there a trick, when i have to push the button on the card.
How can i check, if the card is in the right mode to write the rom? When i push the button, the light is changing the coulor frequently. Is this the right mode?Do i have to reboot, after pushing the button. I´ve found someone who has modified the rom, for rx470 cards, so that i can be sure, it works.
Can somebody tell me, what i´m doing wrong?

And hopefully sombody can help me to optimize my cards.

Many Regards,
Scandalrosi

You should be able to reach over 700 h/s with almost any card, after flashing your cards.
Before flashing you need to check what kind of memory you have on your cards (mostly hynix/elpida/samsung), then use a bios corresponding to that memory, or edit your bios by yourself with Polaris Bios editor 1.41 (basically you copy the 1500 MHz memory strap to 1625,1750 and 2000 Mhz mem straps for hynix and elpida, for samsung you copy 1750Mhz strap to 2000MHz)
For flashing the ROMs succesfully, you need to close de miner and open atiflash in admin mode.
Last thing you have to do is using WattTool to overclock memory frequency (check the differents threads about benchmarks to get an idea of the settings you need)

If you pay for electricity, i would recommend you to use -a 2 mode, which works very well on the RX series too.
"-a 2" low power consumption mode for 290/290x cards. A bit less speed (1%) but less power consumption (10-15%)."

About the lagging, it's hard to tell.
What's your CPU ? Do you use your computer for other purposes than mining?

First, many thanks. But this all doesn´t work with my cards. I have 4 x RX 470 Nitro+. Only 3 of them are showing in the flush tool. It looks like, the 4.th one, is another model. This card has totally different values, compared to the other 3. And it is slower, then the others. OK. The othe 3 Cards all have Samsung memory. What i´ve done. Reboot PC. Start ATIFlush with Adminrights. Choosen the card i wanted to programm. Push the button to search the rom file. Then hit the programm button. Then it began to program and in the half it stpped and showed the error message.
"Unable to delete ROM". What can i do else?

And one more question. Is there no working programm, to mine litecoin with windows. Doesn´t matter wich pool i choose. They all have great instructions how to enter their strings into the bat files, but when i execute them, it always shows --srypt unrecognized option
Is there anywhere a working tutorial how to configure the minig software. The only i got to work is.....tatttaaaa Claymore's CryptoNote GPU Miner v9.7. But only when mining over minergate. I tried out sgminer. Downloaded the programm and the source code. Same error message.--srypt unrecognized option. How do i have to configure the tool. I can start sgminer.exe without errors. It askes for an url then. But as far as i start the bat fill, with the --scryt in it. finish....

Sorry. I hope i could explain what i mean..

Regards, Scandalrosi

Forget about mining litecoin with GPUs, LTC has been mined on ASIC since 2014, GPU mining is pointless for these.

As for the bios i'm editing using cmd in windows (admin mode), but never encoutered the problem you are describing.
Make sure you are not using the miner while rewriting the BIOS. Maybe your cards have a dual Bios and one of them is locked (small switch on the top of the GPU, google it to find pictures). Switch of your rig, switch to the other bios, restart and try editing again.

I didn't try Sgminer so i can't help you on this one. If you want to give it a try you should post on the miner's specific topic
