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

[supertux1]

Hi,

I'm running a dual miner Claymore v9.3 rig with 6x Sapphire RX480 Nitro+OC 8GB cards (11260-01-20G) - Samsung Memory
Power supply is a Corsair ATX 1200i.

Modifications:
I'm using v4.rom from Jukebox on five of the cards (GPU0,2,3,4,5) and vdrop+.rom on one of them that has issues. (GPU1)

(These ROMS appear to overclock the memory and/or tighten the timings while reducing the CPU clock. vdrop+.rom is slightly more slower/conservative.)
I use WattTool-.92 to drop the voltage on all of them by 100mv

The Driver is 16.12.1 (patched to pass driver signature checks.)

Power from the wall is about 1050W and card temperatures are around 63C.
The rig is stable in that it does not hang or crash, Claymore is setup to reboot the machine on error, and it'll run all day like a champ:

Code:

ETH - Total Speed: 175.402 Mh/s, Total Shares: 1879, Rejected: 109, Time: 08:14
ETH: GPU0 29.727 Mh/s, GPU1 29.268 Mh/s, GPU2 29.792 Mh/s, GPU3 26.966 Mh/s, GPU4 29.807 Mh/s, GPU5 29.843 Mh/s
 DCR - Total Speed: 5262.069 Mh/s, Total Shares: 4445, Rejected: 84
 DCR: GPU0 891.816 Mh/s, GPU1 878.032 Mh/s, GPU2 893.747 Mh/s, GPU3 808.985 Mh/s, GPU4 894.204 Mh/s, GPU5 895.285 Mh/s

Here is my config:

Code:

-r 1 
-retrydelay 5
-epool stratum+tcp://daggerhashimoto.usa.nicehash.com:3353 
-ewal xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-epsw x 
-esm 3 
-allpools 1 
-allcoins 1
-estale 0 
-tt 75

-fanmin 66
-fanmax 100
-dpool stratum+tcp://decred.usa.nicehash.com:3354  
-dwal xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-ttdcr 75

Now here is my concern / question: Is such a high rejection rate normal?

That's about a %5 reject rate for ETH and %2 for DCR.

Hi everyone!

I have a serious problem!!

I have  a 980 Ti AND a GTX 1060, I can get the GTX 1060 mining on opencl at 19 MH/s BUT the 980 TI can only do 3 MH/s!!!

I'm sure this is a DRIVER PROBLEM, but I can't figure out which driver I could install that SUPPORTS BOTH CARDS!!

NVIDIA DRIVERS:
9xx cards in Windows 7 x64: just use latest/recent drivers from Nvidia website (for example, 368.81). Note that latest 372.54 is slower than 368.81.
9xx cards in Windows 10 x64: you have to use old drivers (for example, 352.xx) and miner built for cuda6.5.
10xx cards in Windows 7 x64: just use latest 372.54 drivers from Nvidia website.
10xx cards in Windows 10 x64: just use latest 372.54 drivers from Nvidia website, note that you must have Win10 Anniversary update.

Can anyone help me get the full potential of my 980TI???

Thank you!!!!

Hello every one,

I have an odd behavior from dual mining

W10 pro
claymore 9.3
4xRX470 with 1500 straps

if I mine ETh only, everything is normal, after memory overclock, I'm 29Mh/s.
The probleme is, if I dual mine (DCR or SIA), my ETH hashrate is going super low. The only way to not loose too much hashrate is to choose DCRI 1 or 2 but in this case, it's almoste useless to dualmine.
And my memory overclock boosted the hashrate well in single mining but not in dual mining. +100 Mhz on memory? same result in dual mod, +10% in single mode.

I can see the monitoring showing that the GPU is almost always below 1 000 Mhz, even at super low dcri, at 10 dcri, it stays around 850 Mhz in dual ETH SIA.
In ETH only mode, it is higher than 1100Mhz. My GPU are even hotter in single mining than dual!!!

It was the same thing at stock clock/bios. When I was just testing, I lost 30% of my ETH hashrate when I tried dualmining on DCR (using the super basics configs that was as exemples in the readme.txt, I even didn't change the wallet adressses...)

I do use the GPU_FORCE_64BIT_PTR 0 and others.

Does someone have an idea?

thx folks

@supertux1

I did nearly the same as you.  use v4 for all cards and and lower the power consumption with watttool.
I use the pool ethermine.org and at least clay 9.3 reports 0 rejected. For dcr i am on suprnova with ca. 1.5 % rejected shares.

Yeah just one of my cards can't take v4 for whatever reason and I verified it stand-alone being the only card in the system, fan %100 and
no volt drop to eliminate heat and lack of power as a cause - still fails. It takes the other bios just fine. (Lower quality RAM? Who knows.)

I tried testing the miner with just one card and only mining ethereum to eliminate any power drop or dual mining interference as a cause
and I still get quite a high percentage of rejected shares. (good cards and crappy card alike.)

My next options are to try a different mining pool, try the stock bios, try the older non-patched driver, try without WattTool settings etc...

I think what I might do if the simple fixes don't yield any results is to make my own bios.

That would be taking stock (non-oc) bios which runs the CPU @ 1260Mhz and copying the just the ram timing from 1750 to 2000.
Then I'll see if that's stable. If it is, I'll use WattTool to change everything else.

FYI I used to run my main monitor off of the VGA port built into the motherboard, but I found that WattTool will not work unless a display is plugged into one of the cards. Sort of like how AMD Settings won't run unless one is hooked up. I think the driver does something to itself when it detects something.
(That frustrated me to no end and paid like 75 cents a day in extra power costs till I figured it out.) I have ordered an HDMI dummy plug.

Hey guys, I have 2 gigabyte rx 480 8gb (Samsung) and 1 msi rx 470 (micron) and they were mining ok (27 for the gigabyte, 25.5 for the msi) I tried hashing with Sia and they dropped to 6-7 mhs per gpu, I tried claymore 9.2,9.3 and 8. They all do the same albeit slightly different hashrates, but still very very much lower than their original hashrates, anyone can tell me what I'm doing wrong?

[qqqq]

After almost 14 days in solo with 650 mh\s block fas found. Ver 9.3 is ok. Confirmed.

 -dcri 120
try -dcri 8 or 6 if you want some eth

GPU0 t=87C fan=68%, GPU1 t=75C fan=51%

see, you have very unhappy card (s)

@ JDOPE also

Don't be so greedy ppl

[AriesIV10]

Does anyone have a solution to the first GPU1 not working?  I have swapped out GPUs, but GPU1 never works.  I have reduced to 5 GPUs, 4GPUs...but still GPU1 does not start.

[djraven911]

-Ethi command NOT working at all

Seriously guys, im not a beginner, nor an expert, but i tried all values with this -ethi command as i have 2 GPUs in my pc and the one i use for desktop i want to reduce its speed. So as i see -ethi is the only way to do this targeting a specific card. However no matter what value i use both gpus mine exactly the same speed. I am eth minign only. What am i doing wrong?
How can i make one of the cards run at 90% so i can watch also a blueray without bluescreens?

I manage to do this very easy in Minergate software, but that software is crap and needs restart almost every 48h. I prefer using claymore as i do with my other miners and have the mining speed going to dwarfpool and not minergate...

Thank ya all!

Gongrats! Wow, that is very Long for 650 hm/s or?
Ob what for a Pool do you Mine...

It's not greed, it's a feature that exists for a reason, if it's not to be used then why was it done?

[delle54]

The default -dcri 30 has a reason, because everything above that will significantly lower the MHs/s for ETH! Preferably use less -dcri. Test it with the +/- keys.

[jackbox]

That is not accurate. On my cards I have to use a lower -dcri to get a higher MH for ETH. At the default the other coins are getting much higher rates at the expense of ETH. I use around 11 on most of my cards (20 on one in another machine) that maximizes ETH while still getting a reasonable hash on DCR or PASC. It is there to find the sweet spot for your particular card. The default of 30 does not necessarily mine the most ETH.

[cashen]

I'm currently mining @ ethpool.org and I noticed the page shows my hash as correct, 190Mh/s, with 145 shares, 5 stale, 0 invalid.

My client shows 443 shares, 0 invalid.

This has been running for about 2 hours, 45 mins


Shouldn't the shares match?


EDIT: Nevermind, I see the website shows "last hour"

Mow many shares should 190Mh/s get in 60 mins?

[Pustul]

@pustul
    I currently am using GTX 1060's and I braved the over clock world. I can push mine to near 21 but just shy before I blue screen.  I have to just accept that 20.5 is solid and go with it. Yours will go a bit faster but don't get greedy as all you will get is an unstable machine. Been there. Flaky board is the reason rig01 keeps dumping. New one in the works.

@Claymore
   Many thanks for the S/W and your time. Single (eth) for now but going to go dual when rack goes live.

I have 2 1060's and 2 1070's which are just mining ETH.

The 1060's (6GB) are set to core -200 mem +750 power 94% and they hash at 22.6 consistently.

The 1070's are similar settings but power at 84% and they do 30-31mh/s.

whole rig using around 600W.

Yeah that's what I'm talking about, how come my 1080 is doing only 25mh/s when your 1070s are doing 30-31mh/s? Are you using windows or linux?

Bump, anyone knows how to get more than 25 mh/s on a gtx 1080 on windows? I am still having trouble figuring which drivers to use. I guess I should switch back to Ubuntu but this is my gaming rig :/

[cashen]

Yes, trade them for my 470s.

[delle54]

That is not accurate....

Did I say anything else?

[cashen]

Does anyone have a solution to the first GPU1 not working?  I have swapped out GPUs, but GPU1 never works.  I have reduced to 5 GPUs, 4GPUs...but still GPU1 does not start.

Check WattTool and see if the core clock dropped. If so, hit the set on the core clock table and it should jump back.
