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

[drr0ss]

i am only getting 48.76MS/S with 3 R9 280x vaporx cards

pls advice how to increase hash rate

In my opinion it would be better to sell those cards to some gamers and get a single rx480. You're getting 16,25Mh/s for each x280 with a power draw of 660W for all 3. This will be worse every day.
With a single rx480 and a proper bios you can get 30-32Mh/s with less than 150W, this is a -34,37% total hashrate (48,76 vs 32) BUT with a -77,27% less power draw, less hashrate decrease, greater resale value and warranty.

I sold my 7970 in july for 90€ with some other older cards (5850, etc.) to pay two rx480. Now those rx480 are amortized (ROI).

Also you can try to go for a dual rx470 and get a decent ROI for the second one.

EDIT: I pay close to 0,2€/kWh

You can mine Expanse, the DAG is smaller and there is similar profitability last I checked.  Depending on power costs you may want to sell and upgrade.  Probably still decent resell on them, and 470s are easy to get now ($200-240)

You missed something essential, reduction of hash rate, results to lowering the power consumption, 5 under-volt 280x now consumed lower than 900w....
Anyway, modded 470, 480 is better choice.

BUG: w/ new DAG and claymore miner.

Up until recently ... the following has worked fine:

Mining EXP and SIA or DCR on my rig on 2 7970's

As of the latest DAG .... this now causes a crash when switching to devpool (subsequently having to change epoch to ETH's epoch), the DAG creation takes 2x longer than usual and at the end of it the machine reboots w/ bug check of a hung device thread status.
Ive repeated this across multiple sets of cards - so its not hardware related.

If you use same version and it started to generate DAG slowly - reboot PC, it's not miner issue, drivers or hardware failed. I have several rigs turned on right now and they work fine with latest 7.2 on Win10.
What version of the miner do you use? What pool do you use to mine EXP?

Using win7 x64, 15.12, have tried miner 5.3 and the latest 7.2 .... same issues. I dont understand how its a hardware problem. No cards on rig exhibit this problem when generating either EXP or ETH DAG on miner start, only while mining and switching to devfeepool has the problem shown up(going from EXP mining to devfeepool mining). Could it be size of larger new dag and exp dag cant coexist on a card? ( I dont know how the ongpu dag creation works - is the old DAG discarded prior to the GPUs generate a new one? ... if not then its easily a DAG size issue)

Completely different GPU's on this rig exhibit same problem ... I doubt all the GPU's are failing ..

I just tried to mine EXP, it mines it, after a few DAG switches it still works, no rejected/invalid shares. EXP has epoch #13 and ETH has epoch #79, so it takes in about 1.5 times longer to create DAG for ETH.
Try to specify "-allcoins -1" option, see readme for details. If it does not help, ask here if someone mines EXP and has same problems, this way we can confirm that the problem is not in your hardware.
PS. If you use dwarfpool (or any pool that accepts wallet address directly) you can avoid DAG re-creation at all, miner can mine EXP in devfee too. Though it seems "-allcoins exp" option was broken in v7.x, I fixed it and I can send you an update.

k previously I had -allcoins 1 .... trying -allcoins -1 now, seems it has started on devfee fine then switched to exp (my pool) and subsequently epoch... just fine as well ... will see what happens when next devfee pool switch comes along.
If this still fails, Ill have to get that -allcoins exp fix from ya.

Hey Claymore, there's a Zcash miners challenge. I just found out by mailing list. The prize is 10 grand for the best GPU and CPU miners, respectively. I think you should join this challenge, your miners are awesome. Here's the info: http://zcashminers.org/

Anyone have any idea why it takes 40-80 seconds for claymore to begin generating DAG on my rx 480 rigs with windows 10 ? this delay happens on all of them. have the latest stable driver (not hotfix, which causes a bit lower performance).

Is my answer not enough? Or may be you missed it:
https://bitcointalk.org/index.php?topic=1433925.msg16422035#msg16422035

yes i did miss it, thanks claymore. gpus are 6x rx480 8gb, 16.7.3 drivers, windows 10 anniversary, cheapeste celeron cpu. will wait for the next versions then. this only happens with the rx 480, no other older cards.

Which particular GPUs including make&model would represent the best investment for dual mining at this moment?  I'm currently debating between the MSI 390, 480 and 1070 but I would like to identify the few out of many cards which aren't plagued with various issues such as improper cooling on GPU/VRMs/VRAM.

Work 15.12 drivers with R-480? I have R-380 rig, but newer drivers (16.xx) decrease hashrate.

[mikhan]

@Claymore
if I connect to a pool with "ETH: Stratum - Connected" but then receive "ETH: Job timeout, disconnect, retry in 20 sec..." message in the log, does your miner switch to other pool after 3 job timeouts? or what is the logic of switching?

[Coreol]

Work 15.12 drivers with R-480? I have R-380 rig, but newer drivers (16.xx) decrease hashrate.

No - RX480 are supported from 16.xx upwards. 16.9.1 works pretty well for me.

Yes it will switch to other pool after 3 job timeouts.

Claymore, hello, could you add for Ethman hashrate metter in tray icon like temperature icons in AB.

Notice GPU2 with 5mh on the first pic and GPU1 Power at 18W.  I have tested them.  If I have 1 GPU plugged it will be the low one no matter what slot I put it into.  The rest run fine.

I have 6 MSI RX 470s and 5 would hash at 20mh and 1 would hash at 4 or 5mh.  I did not know what this was or how to fix it no matter what I did so, I returned the Gigabite Gaming 3 Motherboard and got a MSI Z97 Gaming 5 Motherboard.  This did nothing to the problem.   I also have changed all of the settings in the Bios trying to make a difference.  Still doing the same thing, the first GPU will run at 4-5mh.

Can someone help?

I was mining on Nanopool when it suddenly stopped and now I am having problems in connecting again of not with just one card.

These are the last lines in the log file, can you see something wrong in them?

I hope someone can help out a N00B like me; I'm trying to run the linux version of this on ubuntu 14.04 lts.
In the terminal, I navigated to the unzipped folder containing the Claymore v7.2 mining client and I enter the command sudo bash start.bash into the terminal, I get the following error : ./ethdcrminer64: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory

What am I doing wrong?

Notice GPU2 with 5mh on the first pic and GPU1 Power at 18W.  I have tested them.  If I have 1 GPU plugged it will be the low one no matter what slot I put it into.  The rest run fine.

I have 6 MSI RX 470s and 5 would hash at 20mh and 1 would hash at 4mh.  I did not know what this was or how to fix it no matter what I did so, I returned the Gigabite Gaming 3 Motherboard and got a MSI Z97 Gaming 5 Motherboard.  This did nothing to the problem.   I also have changed all of the settings in the Bios trying to make a difference.  Still doing the same thing, the first GPU will run at 4mh.

Can someone help?

The 4mh Issue:

-only 1 gpu installed (I removed 5 gpu's until I can resolve this issue)
-set the Bios to Gen1 for all slots
-tried moving the 1 gpu to different slots on mobo to include installing directly on the slots on the mob
-uninstalled and reinstalled all versions of drivers (16.9.2, 16.9.1, 16.7.3)  I now have 16.9.2 installed


Still having the 4mh issue on the 1 card that I have installed.  Anyone have a solution?

----------------------------------------------------------------------------------------------------------------------

The 4mh Issue

in all of my cases  my 4mh issues  are not card specific  ie  one card would show 4mh  pull it put in a completely different card, in a different slot on mob and  still have a 4mh issue.

Example:  This is a different gpu in slot #3 - Same Problem:

Make sure you install an older version or compatible version of libcurl. If you are on arch, this package should help. Works for me.

UPDATE ... looks like the -allcoins -1 works , 9hrs w/o stability problems.   Guess generating the ETH dag first is the key =)
