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

[SummersideGuy]

So, i readed much posts and i am confused little, is latest claymore miner works with win7 blockchain drivers or what is best to use to have back results on our RX 400/500 models back to 30mh/s ?
I know there was much argue about that but there was also much incorrect answers so what is final conclusion, because i refuse to use win10, only win7.
What must be used to work with undervolt and etc?

There is nothing that will work with win 7 in combination with the new block chain driver. it has an issue under windows 7 if you want to use it you will need windows 10
Your only solution is to mine another Ethash coin that is on a lower dag

Recently bios modded two 4g rx 470's and afterburner adjustments. They both run at 27 mh/s but a couple times a saw them both, at the same time go up to 28.5 for a minute. Is something holding them back from staying at 28.5?

In june with my rig i got 240 MH/s to 242 MH/s, i change nothing and now, 3 month later the MH/s drop 230 MH/s, i tried aug 23 blockchain driver, the result, i got 248 MH/s, but unfortunately i met issue with stabilty not good.
On this topic I read this "It should be higher. Try increasing the -ethi to 8. My eight card mixed RX 570/570 4GB/8GB rig is getting 28.5 to almost 30 MH/s dual mining UBQ."

What is this setting? -ethi to 8

It's the ETH instensity. The command line options are listed in the readme and the OP.

Hello Vann, this setting is not specified actually in my bat, do you think it can be change something if i had it?

It depends on the card what seting gives the best result. The default value is 8. Only way to know is to add it and try different values.

On another note, the new blockchain driver raise the power usage of your cards alot. If your mod was tight you may have to change some things like power limit or max temp.

Why would you say that? Comparing to the 16.11.4 I was running before both unofficial beta and official blockchain beta drivers make rx4xx use LESS power in a range of 2-5%, measured at the wall.

Whats working for you for stable undervolts? AB beta16 or Overdriventool?

Hey, I am not sure if this is the right place to ask:
Rig continually worked until yesterday morning, and then in logs I saw devfee couldn't mine, and tried several times during night on eu1.ethermine.org pool without success.
I am trying to connect since then and I get the error:

ETH: Stratum - Cannot connect to eu1.ethermine.org:4444
ETH: Stratum - Failed to connect, retry in 20 sec...

I tried:

• older and latest version of Claymore
• restart miner/PC
• restart router
• options like -esm 0-3
• different miners
• different pools
• turn off windows firewall
• turn of windows defender
• updated drivers
• googling similar problems with no success

I'm using the basic configuration:

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 eu1.ethermine.org:4444 -ewal 0xXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX -epsw x

I haven't done anything network-wise since then, so I doubt port could be the problem, and there were no Windows updates in the meantime.

Do you guys maybe have an idea of what might be the problem and what could I do more?

Hello, @Claymore, after upgrading to 10.0 I noticed miner drops hashrate with no reason, i.e. it can dig for several hours at overclocked freqs (28-30 per 480/580 AMD card), and then drop to 23-24 like it was defaulted. Noting suspicious in log, affecting different rigs (Windows 10 LTSB, AMD blockchain drivers). After restarting miner it goes fine again.
using -minspeed together with -r 1 is not convenient, because it's enough just to restart miner, not a whole rig (could you program different behaviour of "-r" key for GPU fault and minspeed not reaching?)
I reversed to 9.8. Please, do something )

there is a 12-hour example how often it drops

[shYter90]

with the updated version of Polaris Bios Editor using the supplied timings instead of copying the 1500 timings I get roughly 0.2 - 0.4mh more per card

There appears to be two versions of Polaris Bios Editor V1.6 ?
The one from https://github.com/jaschaknack/PolarisBiosEditor has the "One Click Timing Patch" option and the other has the option "Apply Ubermix 3.1 Samsung Timings" - both say they they are version 1.6.
I've been using the "Ubermix" version with no problems - can't remember where I downloaded it from.

Does anynoe know what the difference between the 'One Click' and the 'Ubermix' timing are ?
I'll have a go myself and see if I can spot anything - I may be some time figuring this out.

There are different forks of PBE listed on

http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx

The jaschaknack PBE v1.6 is the most updated version. The 'one click timing patch' includes the Ubermix v3.1 Samsung timing as well as performance straps for other memory types. It depends on the memory type/types detected on which performance strap is applied.

Is it possible/better to apply timings with "one click button" and also set parameters for downvolting each GPU ?

[kkourmousis]

How many of them do you have?
Have you checked HWInfo for memory errors on your cards?
What is your power consumption per card?
What are your overclock / undervolt settings?

Well I only have Hynix ones but those numbers does not sound too bad..
If I would change something I would increase the -dcri parameter in order to reach 900mh on DCR (the sacrifice in ETH actually has a minor stability benefit - less fluctuations- at least for me)

Windows 7, Robinhood drivers, AB 4.4.0 beta 16, Claymore miner v10.0
My core clocks  are locked at 1300MHz for both rigs and no matter what I put in AB it won't change a thing, so I change it in batch file with -cclock
My -dcri value is 25 I think it's best for me.

Is ETH+LBC dual mining more profitable with a new v10.0 miner?
Thanks

• Are your cards 8GB or 4GB?
• Your clocks are very high, have you checked HWInfo program for gpu memory errors? I bet you have millions...
• I have foundr -dcri to have impact on fluctuations. Personally I chose to sacrifice some ETH speed for some stability there (I am mining at -dcri 30)
• Why do you use AB, why don't you set core and memory clocks and voltages, all from the bat file? Claymore did so much work for this, give it a try
  These are my bat parameters: -esm 0 -estale 0 -asm 1 -dcri 30 -cclock 1140 -cvddc 875 -mclock 2150 -mvddc 850 -tstop 80 -tt 70 -fanmin 15 -fanmax 85 -mode 0
• As for the most profitable coin to dual mine, best thing to do is try them all, write down your numbers and do your calculations. But first you should stabilize your settings

If you find win7 not working with blockchain driver, try this unofficial driver: https://bitcointalk.org/index.php?topic=2068446.0. I can confirm it supports 6GPU with win10, even if VGAs are mixed RX4xx and RX5xx.

On Win10 you can go with official blockchain driver.

With blockchain and unofficial driver above (on Win7 and also on Win10), I use the following to tune:
claymore parameters for clocks, voltages, power limit:
-cclock
-cvddc
-mclock
-mvddc
-powlim
and for fan speeds and temperatures: WattTool

I have rx570 and rx580 both with Hynix, on win 7 they are at 30mh/s. With new Claymore miner, undervolting works with AB 440 beta 16, but you can set it in a bat file.

How many of them do you have?
Have you checked HWInfo for memory errors on your cards?
