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

[Walrusbonzo]

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.

gpuz power in not the same as wall power !
i've :
4*470 on ETH only, ~1075/1900 980mv , 750w at wall
4*470 on ETH+DCR, ~1150/2000 980mv, 850w at wall ( dcri 25 with v9.0, was 35 with v8.1 )

That's some high power consumption.

My 6 RX480 rig pulling 178mh/s solo mining ETH only pulls 810w from the wall

1125/2050...... 880mv though

- A lot of minor improvements and bug fixes.

Hi there

It looks like there are still some minor issues with your implementation of NiceHash version of Ethereum stratum protocol. There is no eth_SubmitHashRate method in the NiceHash specification, but your program sends this request few times a minute. As the consequence, a lot of "Invalid stratum message" errors are being recorded in server's log file.

You can use "-erate 0" option for now. In next update miner won't send this message if "-esm 3" is specified.

When i set core voltage below 935mV like say 900.. The gpu still uses around 925-935mV.  How do you achieve 880? And when i go below 1100mhz it slightly affects hashing speed.

I know its not the same. Thats why i stated that the cards are undervolted.

So lets say they each pull 40 watts more than what GPU-Z shows. that is 92.5+40=132.5 watts for each and 530watts for all 4 cards. Even if the rest of the system pulls 170w  half idleing which i highly doubt ( x2 240 and 1 ram with 1 hdd) that adds up to 700w. I will get a kill a watt next week to verify. I should safely assume i am safe considering the cards ran with 20watts more each for a week when they were not undervolted.

All of my DCR shares are getting rejected using 9.0. I mine on supernova (dcr.suprnova.cc)...any idea why? It has been working fine with 8.1.

I believe this problem is related to this pool, sometimes it does not send response to auth message for some reason but still sends jobs, so miner mines but pool does not accept shares.
Miner will reconnect automatically after 10-15 invalid shares, usually the pool accepts auth message at second attempt.

Suprnova Decred pool is complete and utter garbage.  It should be blacklisted from the internet. I would get 95-100% rejects on most rigs, best case like 5-10%. Switched to coinmine, now get under 1% reject.

Some suprnova pools are ok, many are junk.

Hi guys,
I am getting around 164 mh/s on eth and around 4900 on drc
http://imgur.com/a/mDwd6
I am with 6 470 cards and the power consumption is around 1200 w, is this normal? I overclocked the cards to 1250/2050, -100 mv with the trixx tool.
Is there a way to reduce that consumption?
Thanks!

Try a lower core clock like 1150, 1125, or 1100 and check power consumption.. should only reduce mhs a bit.. I use 1130.. also try more than -100mv?

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

[miner582]

I believe that when card submits share the speed shows reduced temporarily immediately after.  That's why you get fluctuations.

Claymore, could you confirm this?

Ah. I was a fool. Did that in Wattman and voila. 885mV and lower consumption now. Still sam hashes. Thank you.

HD7950 cards lose a hash or two no matter the dcri value.

Mode 1 mining Expanse :
HD7970 (856mV) cards hash around 24mh/s using "dcri 7" in v9 and v8.1.
HD7950(850mV) are stuck at 21-22mh/s+ in v9 compared to 23mh/s+ in v8.1.

Mode 0 dual:  performance appears to be similar in v9 and v8.1.

I'm still running version 7.4 and it works fine.  Is there any reason to upgrade to 9.0 if you've got old GPUs? (280/290 etc)

How works voltage on RX ?
Testing differents values with 4*470.
980mV core and 980mV mem. Give ~850w at wall
950mV core and 980mV mem. No change, give ~850w at wall
950mV core and 950mV mem. Give ~790w at wall !
I can't believe put -30mV on mem give -60w at wall !

Huge DCR performance boost on 290 when dual mining, you might be power limited though.

I have R9 390 and I'm using 8.1 but there's no rela difference from 7.4. When I try v9 it only works with same or less eth speed and same dcr speed, it can double the dcr speed but no matter what I do, it crashes the whole rig in about 10-20minutes, tried lower ethi, lower dcri, more vdcc, if it has more hash than 8.4, it crashes.

[miner582]

I am getting on red when I start the miner "error on parse command line 32 of config.txt" which is -wd 0 in my case. I am running ethos 1.2 (linux) however the miner is up and running.

No error reported back on v8.1

Something is limiting it, you need to find it yourself. No crashes here, it just starts throttling when it hits power limit. +50% to numbers below and still power limited.

Hi Guys, this is my first post here on bitcointalk.

I have been using claymore 8.1 for a while now, on a rig with 6x RX470 with modded bios, and was getting around 169Mh/s stable.

with claymore 9.0... this is awkward, i can't seem to get more than 44Mh/s, tried dcri from 1 to 40, no changes whatsoever
Increased ethi to 16, same thing.. nothing changes.

Am I doing something wrong here?

Should core and memory mV match?

You didn't mention your rig stats, such as PSU, OS, your command line etc. so I'll take a WAG at it. Version 9 draws slightly more power than 8.1. so I would suggest using the -li command line option. If the rig runs better at something like -li 5 you can toy with that to get the best speed you can........and know your PSU isn't enough now. Other than that, I got nothing for ya.

Hi I just recently picked up a few msi rx470 4gb and they run very stable but I'm running about 20mh with stock clocks and no mods what is the best way to get some more speed I'm used to playing with r9s so the rx cards are new to me thanks for any help
