I did not know that it use FP64 as none usual algo does

even if it didnt the 1070 isnt 2x faster than 290x/390x on any algo not even close

eXtremal pls could you make payout: AeLqb8XdgRyXGdhJ7rEJnknByQ7AWiwmNm

thanks a lot

I know this is just cosmetic "bug" but I catch it at first few minutes of mining

(ST/INV/DUP): 1265x 7ch(19/4/4) 159x 8ch(5/2/0) 21x 9ch(1/0/0)

I assume that first is 7 ch type 1 second is 7-ch type2 and third is 7 ch type 3
And since it is 1265x of 7 type it cannot be only 19 of type1  etc etc

I am quite sure those are not the corresponding numbers of chain types but are invalid or stale shares etc.
I don't remember which number is invalid or stale but I think that is not that important here.

UPDATE: Oh, actually it is in the front (ST/INV/DUP)... should be Stale/Invalid/Duplicated

[Hyp0crit]

Anyone tried mining this with 295x2 ?
What speed you get and which drivers to use.

Just pointing for anyone mining with older 290x ive been mining now for a while with 2x 295x2 and getting 0.44 cpd per core total of 1.76 cpd. I use newest drivers because of windows and older drivers just doesnt work good (no signal and other crap).
My rig have also even older 7950 cards and they get 0.23 - 0.27 cpd per card.
Next week I receive some rx 470 and will post result after.

Hello,

Stupid question but i don't find how to change coreclock, like this for exemple ?

corefreq =       ["1250", "1250", "1250", "1250", "1250", "1250"];
memfreq =        ["2150", "2150", "2150", "2150", "2150", "2150"];
powertune =      ["850", "850", "850", "850", "850", "850"];
fanspeed =       ["50", "50", "50", "50", "50", "50"];


Also i have a problem, when i change

windowSize = "4096";  to   windowSize = "8192";

The miner crash, i have 18.3.2 drivers and 10.2.2 miner version, i can only get max 0.3 with stock settings (RX580 armor 8gb).

Can someone help with this config ?

fanspeed =       ["50", "50", "50", "50", "50", "50"];

don't change it with xpmclient, just put +0 in all fields.
coreclock and other things change with msi ab.

after you change anything in config.txt delete all kernel files. restart xpmclient and compile new kernel files.
0.3 is too low, it should not be less than 0.42 even if you have slow celeron cpu.
btw, i have best expirience with blockchain drivers.

Hello, thank you ! i followed your advices and i have now 0.4 !

I cannot tune the voltage with AB so it consume 1200W for 6 rx580 ... that's a lot, i'll try to find something to undervolt them.

[Hyp0crit]

2x295x2 & 2x 7950
1650w
Btw did you check afterburner settings for voltage control.

Thank you, i didn't checked it, so now the better i can get is :

6 * RX580 msi armor 8gb :
950W
2.28 CPD

Can we do cloud mining? Do you know of an updated tutorial?

Next miner update:
http://coinsforall.io/distr/xpmclient-10.2.2-beta.tar.gz
http://coinsforall.io/distr/xpmclient-10.2.2-beta-win64.tar.gz

No more invalid shares with odd targets (including target="11"), previous miners have 3-4% invalid share rate.
Remove obsolete parameters from config.txt
Add new parameter to config.txt:

# Maximal bit size of multipliers using with primorials 13, 14 and 15;
# Default values are 26, 33, 36
# Less values increases prime probability, but sieve generate less candidates
multiplierLimits = ["25", "31", "34"];

And also some useful hints for getting more CPD on different GPUs with target="11":

Radeon RX Vega

sieveSize = "630";
weaveDepth = "36864";
multiplierLimits = ["25", "31", "34"];

Radeon R9 290 & R9 390

sieveSize = "630";

Radeon RX 4xx & RX 5xx

windowSize = "8192";
multiplierLimits = ["24", "31", "35"];

coin young. only five years ... eXtremal has not yet written an instruction. We must wait.

Five years in crypto is like 1000 years

Pool not stable & disconnect frequently any update ?

[Rawhide9000]

I am seeing the same thing as rockallnight posted. All of my miners are randomly disconnected and connecting to the pool. It looks like this in the window:

GPU 0 found share: 7-ch type 1
GPU 2 found share: 7-ch type 3
Connection lost, reconnecting...
Connecting to frontend: coinsforall.io:6666 ...
Connecting to bitcoin: 151.80.96.105:60000 ...

Work received: height=2657522 diff=11.666903 latency=1256ms
GPU 3 found share: 7-ch type 3

The latency is also super high, much higher than usual. It is normally in the <130 ms range.
A ping of coinsforall.io shows a 20% packet loss.
--- coinsforall.io ping statistics ---
249 packets transmitted, 199 received, 20% packet loss, time 248475ms
rtt min/avg/max/mdev = 109.241/133.198/387.692/40.559 ms

The xpmforall.org pool also shows similar stats although I did not run as long:
--- xpmforall.org ping statistics ---
70 packets transmitted, 57 received, 18% packet loss, time 69147ms
rtt min/avg/max/mdev = 109.909/131.011/324.011/32.249 ms

I also ran a traceroute and tried to ping some of the intermediate routers to see if it is the ISP or the destination, but none of those addresses are pingable, which is not unusual.

It was internet connection problem, now cannot reproduce, ping with 1000 packets from different countries shows 0% packet loss. Pool software works stable.

Working fine here. Havent seen any loat connections.
Check your own internet connection if there is a issue?

[Rawhide9000]

It was internet connection problem, now cannot reproduce, ping with 1000 packets from different countries shows 0% packet loss. Pool software works stable.

Thanks for checking. The problem persisted until 12:54 UTC today for me. Probably something in the middle.
