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

[yun9999]

Anyone have any idea why my NVIDIA 1070 is hashing so poorly?   Any suggestion to what else I can try?  I just did a clean Win10 rebuild, all my previous builds are AMD.  First time swinging at NVIDIA with Claymore.  People reported I should be expecting 28-33MH not the 1.5-3.5MH I'm getting now.

OK this is driving me nuts.  Claymore v 6.2 or 6.4.  I can't hash more than 3.5 MH Eth on any of my new NVIDIA 1070 ( 2 MSI and 2 ASUS).  Just reinstalled Windows 10 64bit and using 372.54 Anniversary update driver

ASUS Card memory - GPUZ shows is Micron.  Let me power off and check the MSI

I might just be reading it wrong, but I just want to confirm... You updated the nvidia drivers and updated Windows to the anniversary update?

Rookie mistake.  I only used the Windows 10 anniversary update driver.  I thought that was a Nvidia  thing , didn't realize there is actually a Windows 10 anniversary  updates as I normally used to service packs.  This fix the issue.  What is the best OC  level?? I am doing +575 for memory and +150 for clock to get 29.5MH eth n 300 sia.  I see others reporting that the 1070 can get 29 Eth and up to 900 on Sia.

P.S Thanks so much for the help

No problem, glad you got it working. As far as overclocking, it depends. There really is no good single blanket answer. The exact type of 1070, type of memory, intensity level, what you're actually trying to achieve (power efficiency? maximum coin production?) etc all play a role. Depending on the card, Samsung memory can be clocked at like +800 to +900, Micron memory and it's as low as +300. read over the readme and this thread again about the intensity setting. default is 30, you can go higher and your sia speeds will increase. Long story short, you have to see what works for you.

[yun9999]

Thanks.  Looks like both the ASUS and MSI are Micron Memory.  =(

[Claymore]

That is exactly what I want. To enable only 1 nvidia card. It worked with 6.3 and older versions but doesn't work with 6.4

Just checked, you are correct, it's a bug with indexing. Intermediate build with the fix (cuda :
https://mega.nz/#!vsxgXJ6J!leiBtmET6npRXNICCW9LWhaIYe1H5t__9HRt1zLnAy8

Thanks! It works now. Cuda 7,5 in 6.3 is still faster then cuda8 in 6.4. 32.7 vs 32.4 with gtx 1070@100watt

It depends on Windows and drivers version, in Windows 10 cuda8 is faster for 10xx.

getting poor hashrates 3.5 mhs for eth and 35 mhs for drc with this miner. I am considering upgrading to the gtx 1060 but stuck with gtx 960 for now

Guys,

I've seen someone claiming this riser can be used not only from 1x to 16x but also from 16x to 16x...

Is this true? Anyone doing this?

Or shall I purchase a 16x to 16x powered riser cable?

Upgrade to the 1060 either version or the 1070 as the 950's and 960's can't hack it with ETH anymore.  Other option is to use windows 7 and old driver or Linux and old driver.

Check OP:

...
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.

For your 1x slot, you can only use your top option.  For 16x PCI-E slot, you can use either 1.  They will both work but I prefer the USB cable version

Thanks! Already ordered 12 of those. Just to start...

Anyone running 5 or 6 GPU NVIDIA 1070 rigs?  I can get it to hash at proper speed now but they will start crashing if I run more than 3 per Rig.

The 1070 needs about 150W each from the wall. So if you have 6 cards, you need at least 1100W power supply.

I have a EVGA G2 1300w, it's not power.  I also test everything with my Killawatt on the 120V before moving it to my 240V garage setup.  I have many AMD rigs just first time dealing with EVGA and seems like there's so many caveats.

Now I get the following errors and it would crash
GPU0: Gpuminer cu_kd failed 30 (28), unknown error
NVML : cannot get current temperature , error 999
NVML : cannot get fan speed, error 999


Also what epoch level should I set for these GPU?  There was another error I had previous with the DAG file size where they suggest looking at readme.file

You can use the PCIe 1x USB 3.0 powered riser in a 16x slot.  The little 1x card works because of the little gap in the slot that allows it to sit properly in a 16x slot.   I've had to wiggle it a tiny bit to make sure it was seated properly but other than that they work well. I am using those risers in 4 different 16x slots. They work with no issues.

The ribbon cables are different. When I realized I could use the PCIe 1x riser cards I quit using ribbon cables entirely.


Full disclosure: I sell these risers on ebay. (Version 6, newest riser)

There were some comments about running dual power supplies on 1 rig. I didn't see a proper explanation and someone said they thought it was the problem with their rig so let me explain.

You can run the second PSU a couple of ways.

Option 1:
Use a dual PSU cable that connects both PSUs to the motherboard. It is designed for dual PSU configurations. The cable runs connects the second PSU to the same ground so if you shutdown the power on the rig it properly shuts down the power on the second PSU.

Option 2:
Ground short plug
The plug goes into the slot where you'd normally connect your PSU to the motherboard. It completes the ground circuit so the PSU will turn on.  However it stays on and never turns off unless you use the switch on the back of the PSU or you shut down the power via surge protector or whatever. My EVGA G2 Gold came with the plug. I didn't have to buy one and I didn't have to try and make my own.


The problem comes in when people don't connect the second PSU properly. They don't have the right cable or the plug. They try and cross the wires to the MOBO or do other weird things to get the second PSU to work. As long as you don't do that you should be fine.

I could find photos if people need a better explanation.

I have a couple of these from the old days when I was a BTC miner

16X-16X RIBBON RISERS DON'T BEND WELL--

I bought a few, and could not use them because the would not bend as easily as a single USB 3.0 cable.  They would not fit my rig.  If there is any advantage to using them, I'll never know.  I did buy the powered variety, unpowered ribbon risers are known to catch fire.

QUESTION:  What is the difference, or improvement, in Version 6 of the wide USB 3.0 riser card?  The internet pics all look the same.         --scryptr
