I have a rig of RX470's that do ~27. When I heard about these RX570's doing 29+, I went ahead and got one (or eight) and put one into my rig after some tweaking...

i would like to read data from json format somebody can explain this value: (unknow)

{"result": ["9.3 - ETH", "21", "182724;51;0", "30502;30457;30297;30481;30479;30505", "0;0;0", "off;off;off;off;off;off", "53;71;57;67;61;72;55;70;59;71;61;70", "eth-eu1.nanopool.org:9999", "0;0;0;0"]}

copy whatever original strap you want to mod.. like 1500, 1625, or 1750 from your bios and paste it into the link over the strap thats in the link. the output will be the modded strap and should have higher mhs. I did not make the tool

We now know we can flash 4xx with 5xx bios.
But can we flash 5xx with 4xx bios ? ( to stay with "old" drivers and don't have driver bios signature problem )

Hi Claymore, RX580 8G is not working good in stock just giving 22-23 Mh. Is it because your miner does not support this card yet?

Are you sure about this? According to the first post it should be 15.12? Or is this for non modded cards

hello,

please how can i use claymore on coinmine.pl ?

Does anyone know what causes the
"GPU #0 returns incorrect data" 
warning ?

Make sure to lower the mem voltage (actually is mem controller voltage) to as low as you want your core voltage.. so like put them both at 900mv or whichever value you want

My seasonic 750w gold  kept up for the last week dual mining gpu-z showing 110w for each card. Now they are undervolted. You mean this is not good for longterm? Mind you i have 4 cards not 6.
Well ive been mining for a week with old settings dual mining gpu-z showing 110w for each card no problem. How will you explain this? They are even undervolted now.

Did no Change to my ETH speed but doubled my DCR speed without affecting Power consumption. At least for what GPU-Z used to show in 8.1 and now.


I am getting 29.8 eth and 717 DCR per card with Sapphire Rx470 4GB Nitro with Samsung Ram.
Bios is modded from 1750 to 2k straps.

Ram is overclocked to 2100mhz with 930mV.
Core is 1150mhz with 900mV.
Power consumption is around 92.5w in GPU-Z.
I don't have a kill a watt so i don't know what the system or a single card really pulls from the wall.
There are not many fluctiations in GPU-Z Load or ETH speeds. Only some from gpu and no voltage or default walues seem to fixed. It is so rare.
I am using 17.2. drivers.
Wonder if i can downvolt even more but wont try because my numbers seem good.
Have 4 of these cards in the rig. Running it with a Seasonic 750w Gold psu.

Does anyone have an experience with 1 fan variants of cards for mining? (XFX, PowerColor). Do they run a lot hotter than others because of the 1 fan, or is it okay? Also the MSI Armor RX470's, how's their cooling? I've heard that they run hot because they only have 2 heat pipes, but I don't have one to confirm. I have an RX480 Armor with 3 heat pipes and it runs fine.

Hi,

Running windows 10
Biostar TB85
Having 5 x Nitro+ RX 480 8Gb


But one card is running only 4.222 Mh/s, can someone please help and teach me to fix the problem? Please advice.

Best Regards

wtm calculates nethash from difficulty. Its always an estimate (even for a wallet), but I have to admit the difference is big here.
Personally I think this algo needs a better retarget logic. The base block_time should be 5 mins, while we are mostly hovering between 3-4

Edit: Delisting pasl for now, tomorrow will switch it to calculate difficulty from nethash given by wallet (reverse logic, but it seems to work for pasc)
