Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[cryptoc19]

Guys, whats is the highest value for -ethi that gets you optimum results?

I'm currently using -ethi 16 and I can see a slight increase from the default value (-ethi 8 ). However, when using -ethi 32 or -ethi 64 the miner will report the same total speed, apparently not getting better results.

Any ideas?

check the log. 16 is the highest value,

Version 4.1, like all previous ones, still uses a weird ID scheme and it can be a bit confusing when the miner's GPU 0 is Afterburner's GPU 3 or something like that.

Check my explanations: https://bitcointalk.org/index.php?topic=1433925.msg14659010;topicseen#msg14659010
So there is no way to fix GPUs order automatically, thanks to AMD devs.
But you can do it manually. For example, if you have two cards, you can change their order by adding "-di 10". Another example, reverse order for six cards: "-di 543210".

Ok, not a big deal. But like I said, it can be a bit confusing on a 6 card rig

Really? Ok, thanks!

iam on stability tests right now its great 3 days or more uptime ubuntu 15.04 desktop

installed amd driver from page radeon-crimson-15.12-15.302-151217a-297685e.zip

installed deps.
...

./start.bash

miner should work now if i didnt forget anything ask here i try to help

thank you !

hello , a question , today the claymore miner keeps telling me:

cannot connect to eu1.nanopool.org:9999
failed to connect retry in 20 sec
cannot connect to dcr.suprnova.cc:2252
failed to connect retry in 20 sec


my bat file is:

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

EthDcrMiner64.exe -epool eu1.nanopool.org:9999 -ewal 0x208312414ad16feb261b0f093f780958f60ce1c8 -epsw x -eworker 001 -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal filo1992.1 -dpsw x -dcri 50

It seems you have no connectivity to the sites...

got my powerline adapter! Getting stable results finally with 4x 390x:

HOW did you get such a huge speed in Decred?! My 390 earns twice less! While doing the same speed as yours in ETH. What is the command line? What is the mem/cpu clocking?

I didn't change the clocks at all on these out of the box.  AFterburner says core clock is ~1080, and memory clock is 1500 for each card.  My config:

Code:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

EthDcrMiner64.exe -epool eth-us.dwarfpool.com:8008 -ewal wallet -epsw x -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal SantasNotReal.MiningRig -dpsw x -dcri 55 -dbg -1
PAUSE

I don't have a voltmeter yet (in the mail), so I just upped dcri until I noticed eth hash drop, then kept it.  Much more dcri and I start to lose a bit of eth hash.  I imagine the power/profitability is somewhere closer to dcri 45, but still need to do those tests.

Also, that screenshot was with dcri 65. 55 (current setting) gives me ~840 mh each card.

Edit: Great thinking with the "+" and "-" commands for dcri.  Usability is something that is too often a low priority in the software world (I know, I'm an engineer myself)

Is there a flag to enable showing current GPU temps during run time?  How about fan speed as %?  I don't see anything in the Readme.txt...

i need this too

@claymore
it will be great if u can put these flags
ttks for all u good work

Miner shows GPU temps and fan speed every 30 seconds if you specified "-tt" parameter to manage fans.
I will add "-tt 1" that will not manage fans but will show temps and fan speeds.

You the man Claymore!

u r the best!

As it is now the -tt parameter works perfectly!

For me this miner more steble than genoil. My Gpu upload about 99-100%.

So what happens when target temp exceeds, does it shutdown the GPUs and restart when temp drops down? It will be a nice feature for summer time garage mining.

For some reason, version 4 crashes my gfx card drivers on one of my rigs.  I've moved back to 3.3, and everything is working fine again.  Not sure what is going on...

for a moment there, I thought gtx cards are now supported ....

i have this rig with 2x r9 390 and 1x r9 390x

using gpu-z monitoring (sensors tab), i OC all the cards 1120 clock and 1600 ram ...

looking at sensors tab only one card is at 1120 clock the rest are ~ 930 clock (i'm not sure which card is 390x coz gpuz labels them all 390)

therefore only one GPU is OC'ed...

all ram are at 1600mhz

graphics card tab at gpu-z shows uniform 1120 clock for all cards...sensors do not

any tips?

my 280x rig is uniform, all clocks matched.

edit: these issue occurs only in dual mining mode, mining in ETH only (-mode 1) shows uniform clocks in sensors tab of GPU-Z.

claymore..any suggestions?

Sounds like down throttling, of course.  If cards are getting too hot or drawing too much power, the firmware downclocks them.

Why do you overclock RAM?  It doesn't seem to offer any hashrate increase from my testing.  In fact, on my R9 290 cards, I downclock VRAM to 1125mhz for increased power savings (with no hashrate decrease).

I also find downvolting usually results in more stable hashrates, as the GPU is less stressed and is more likely not to throttle.

How are you overclocking?
AB or with -mclock -cclock ?

Exactly the same  i had, 4 x 390x righ,left stock everything ,even moved down power limits,crash random ,drier 15.12,windows 10,i switched back to 1.0 which always worked best and with it i can run 1100/1500 with -100 mv perfect stable !!
