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

[madmartyk]

Anybody been able to mine ETH at Suprnova with this dual miner? DCR is functioning fine there, but not a single ETH share is reported in my account. The miner says it's stratum connected and submitting shares.. Have not been able to mine EXP at Suprnova.cc too. Any help would be appreciated.

I couldn't get it to work at suprnova as well. but it works great at ethermining.org!!

@Claymore:

What exactly is the effect of the "-etha" option on mixed rigs? I have a mix of 270x, 7870 and 7950. Are these all slow or are the 7950 "fast" for being Tahiti?

Or is it better to leave the miner in the default configuration to autodetect the optimal settings?

As far as I understand, Suprnova does not support Stratum for Ethereum. They mention Stratum on their help page, but all their addresses contain "http".

If you are in doubts, you can check both "-etha 0" and "-etha 1" on your cards and select the mode with best speed, it will not take a lot of time because you can see speed for every GPU. By default miner tries to select best mode but it can be wrong in some cases (if you have middle cards) because I don't have all possible cards for tests.

I just installed, cleared my dag files. Left everything default.
Miner started in etha -1 for slower cards. (auto is default)
results
asus R9 270X 2 gb 13.327 to 13.308
msi HD 7850  2 gb 12.283 to 12.600

mining at ethermine.org and mining ethereum only

So I'm kind of meh.
New to ethereum mining ( but to gpu mining and tweaks that can be done) in just last few days.
Going to try some different pools and such.

I cannot get it to run since version 2.0 ( same for 3.0 ) ... besides the updated miner everything else is the same even the .bat files i start with which work great with 1.2. When i run it through CMD it prompts the parameters and does nothing at all leaving me with the same blinking console interface as before the start. Win7 64 , Tri-x 290 , 15.12 Crimson

Any clue why it throws me back without showing any error or something with the latest 2 versions? i also tried your own start.bat to fix selfmade typing mistakes ....

My 270x are loosing 1%-5% performance with this new version. The same for 7870  

My 7950s are gaining 5%  

Final balance: Not worth the change, at least not with default settings.

Tried -ethi -8192 but it was even worst.

Maybe I'll try to run simultaneous instances; one for the 7950s another for the 270s

I tested v2.0 and v3.0 on stock 270 and v3.0 is faster in both dual and non-dual modes:
v2.0: mode -0 11.5MH, mode -1 12.8MH.
v3.0: mode -0 13.2MH, mode -1 13.5MH.

Probably you use not 15.12 drivers.

[madmartyk]

On the 290x the speed was the same with the 15.12 and the 16.12 drivers.

[crazyearner]

Not sure if am seeing any value to mining both the coins. I maybe make a little DCR a day maybe 1 coin if that. Is this worth the extra power it is using and giving rejected ?

My rigs are optimized with Win 7 x64 and Catalyst 15.12. Trust me, I've tried more than once. But it not a big problem; I'm now running one instance for the 950s with V3 and another instance with V2 for the 270x

Note: I have 5 absolutely identical MSI 270x and they all produce different speeds. Go figure...

I don't think so. I'm using this miner not because of DCR but because it produces better results in ETH single mode.

Here with 3.0 im getting better results with 7950/7970 when dual mining, before it was lowering the eth, now when dual mining its stays close to the solo numbers With 2x 7950 and 1x 7970 im getting 61mh eth and 1200mh dcr. Good job Claymore

Just got my other two cards in, pulled the asus R9 270X 2GB from the riser.
Plugged in a MSI R9 270X 4GB , cleared the DAGs, shutdown booted up
getting 14.5 MH on vers 3.
Just have to hook its brother up....(now where's those other risers)  

Starting to get there.

[Gagana]

How to understand, which particular card is GPU0 etc?

I used the old DAGs to test v3. Could this be the reason? Hummmm.... Testing now!

Why does the program crash when I try to apply overclocking? Please help.

EthDcrMiner64.exe -epool us2.ethermine.org:4444 -ewal 0x54DAcC4a74d5C75f0184E9093c210E6313ACc6Ed -eworker rig1 -epsw x -esm 1 -mode 1 -tt 60 -cclock 1100

[Trimegistus]

As I suspected... DAG recreation won't improve V3 performance

Are you using any special settings? Overclocking?
