Thank you !
Im glad this post helps you

Ok.

Have you also tried to set a bigger pagefile in windows ?

Just found this - you can try it maybe :

Is your error with claymore was "cannot allocate big buffer for DAG" ?
If so, i have already have it and resolved it setting "DSR - FactorS" to 2x on nvidia control panel. (dont really understand what is the relation... but it works)

I dont know. Should be sotre in the registry, but where is the question


Why nvidia control panel dont launch in RDP/TV ? It should.

Can you post a screenshot of your afterburner settings ? and also a screenshot of GPU-Z ?

It really depends on your card.
You need to try differents settings to find whats the best configuration for you.

My card is "factory overclocked".
My current AfterBurner settings are :
- P0 state (1506/3505)
- +131 Mhz Core
- +50 Mhz Memory

I dont really understand why, but depending on the crypto I mine, voltage/frequencies vary.

Right now I dual mine ETC+SIA and I run :
- 1049 mV
- 1392 Mhz core
- 3557 Mhz memory

Windows should detect your 970... Are you sure your card works ?



Yes and no. You have some tuning to do in your nvidia panel control in order to efficiently mine ether with it.
Have a look a this tuturial for GTX 970 configuration

I'm using 384.94 drivers with a hashrate of 20 with my GTX970

Hi,

what do you mine ?

I think you can absolutly use them togheter.

No need to use 2 different drivers, you can use the same nvidia driver for both.

140/145 W for the GTX970 GPU

Yes, I currently mine ETC+SIA with claymore.
You can live test "dcri" effect without stop/start mining using "+"/"-" keys ( Cf claymore readme : You can change the intensity in runtime with "+" and "-" keys and check current statistics with "s" key.)

For me, the default value (30) is fine, but i havent tested it a lot.

I've see a very little hashrate drop when dualmining vs simple mining.
I've also noticed that their is a strict 10x ratio between ETH hashrate and Sia ones (if you have 19 MH/s in ETH, you will have 190 MH/s for SIA) and i dont think OC or not change anything (i supposed sia mining is just using what is not used from eth mining, OC will just raise both hashrates)

Let me know if you find some interessing settings for dcri/OC.

Last windows update raise my hashrate by 0.1 :p
But behavior may be related to GPU (GTX 970 for me)

Did you try to reinstall last nvidia drivers ?
Maybe you can try also beta one (http://www.nvidia.com/download/driverResults.aspx/121776/en-us)

Did you set it to 2x or 4x ?

@TigTex : thanks for this tips. I will try it. Setting P0 manually is boring


@stellan0r : Thanks !
DSR will not increase the hashrate, but i had errors with claymore if not set it to 2x (CUDA error - cannot allocate big buffer for DAG)

Started at 3 MHs with uptodate drivers.
Around 15/16 with old drivers 352.xx + OC

Using latest claymore versions also helps.

Indeed, i put the wrong screenshot - I just update the post.
I've see better result with 2x.

10xx (Pascal) do not have "Optimize for compute" option. It's only for Maxwell arch. (but seems to be activated by defaut for pascal arch). See http://nvidia.custhelp.com/app/answers/detail/a_id/4370/~/what-does-the-setting-optimize-for-compute-performance-do%3F

Only thing needed for 10xx to have de decent hasrate, it's to have at least windows anniversary update (or creators update). (WDDM 2.1)

No i'm not... It's the best i could have. I think its not bad with 970

If you want to use latest drivers for nvidia 9xx windows 10 and cuda 8, check out the following tutorial

I'm hashing at 20 MHs with a GTX 970.

Hi everyone,

It's my first post on this forum and I want to share my experience in how to efficiently mine ethereum with Windows 10, Nvidia 9xx GPU (maxwell) and uptodate drivers.
I'm spend lot of time from various resources to have a decent hashrate, and i though it would be usefull for other to have a complete tutorial.

My setup is very simple : a gaming computer with one NVIDIA KFA2 GTX 970 (Black OC edition).
My current hashrate is around 21 MHs. (and started at 3 MHs, without any optimization).
I'm using Claymore miner and ethermine pool, but you can choose other if you want to.

Here some downloads links you will need if you want to follow this tutorial :

• Latest nvidia driver  - 384.94  as i'm writing : http://www.nvidia.com/download/driverResults.aspx/120905/en-us
• Claymore 9.8 Miner : https://bitcointalk.org/index.php?topic=1433925.0
• MSI afterburner : http[Suspicious link removed]/vga/MSIAfterburnerSetup.zip

Install and configure nvidia driver

Installing last driver should be easy, but some fine tuning is necessary.
Once driver is installed, go to "Nvidia Configuration Panel" (right click menu on your desktop).
You should see the following screen (mine is in french, but i will translate for you what needed to be tuned)



Go to "3D Settings" => "Manage 3D" setting and :

• Make sure "CUDA - GPUs" is set to "All"
• Set "DSR - Factors" to "2x"
• (and most important) Set "Optimise for Compute Performance" to "Yes"

Now you have a nvidia drivers optimized for mining

Install Claymore

Installing Claymore is straightforward (just unzip where you want to)
Create a new file in the main directory (mining_ether.bat) with the something like :

• setx parameters are for GPU configuration
• -epool eu2.ethermine.org:14444 : for using ethermine pool (you can mine in other one)
• -ewal 0xdc7eFDbBE4aFD15c3385d1156b371333550FdDcF : your wallet address. MAKE SURE TO USE YOURS
• -epsw x : pool password if you have one (ethermine don't have)
• -eworker benether.2 : an arbitrary name for your worker
• -mode 1 : only mine ether (and no dual mining - devfee is 1% for single ether mining - 2% for dual mining)
• -allpools 1 : needed for devfee mining

GPU/Memory Frequency (pstate) and overclocking

Start mining before following this part (for having load on your GPU)

Nvidia cards have a special mechanisms for auto ajusting GPU/Memory frequencies based on actual GPU workload.
It's called pstate (Performance State)
P0 is the maximum pstate, that is used when gaming for example.

When mining ether, nvidia drivers dont detect this workload as an intensive one, and then use the P2 pstate.
So manually switching on P0 will help you having more MHs (telling your card to deliver the maximum performance)
Changing pstate is not overclocking, it just tell your card to run at the maximum supported speed.

You can change pstate using nvidia-smi.exe (installed with nvidia drivers in C:\Program Files\NVIDIA Corporation\NVSMI).

I will illustrate this with my GTX 970, but you should have different value depending on your nvidia model.

You need to be "administrator" for changing pstate.
Just launch "cmd" as administrator (type cmd in cortana bar, and right click for launching it as an admin)

First command is for checking your actual pstate


You must look at "Performance State". It should be P2.

You should have something like this (my card is on P0 on this screenshot)



Second command is to get clock frequencies that you card support (without overclocking) :


Just note the two first clocks number (Memory and Graphics). With my card it's 3505 Mhz/1506 Mhz



Then, you can switch to P0 state using the following command :

If you now check with the 'nvidia-smi.exe -q -d PERFORMANCE' you will see that your card is in P0 state.

But… (and here I don't really understand what's happening, just doing observation and tuning )
Launch MSI afterburner.

You wil see that your card isn't at the GPU frequency you manually set with nvidia-smi.
In my case I have 1404/3505.
If you manually slide Core Clock slider you can set GPU to the desired frequency (for me +102)
At this point you will use the maximum frequency (and hashrate) that your card support without overclocking.
If you continue sliding the Core Clock (for example +123) then, the frequency won't go further, but you will undervolt your card (mine is 1212mv as factory setting, setting +123 Mhz will switch to 1187 mv).
Undervolt can be cool as your card will consume less electricity, but can be instable as running high frequencies need power.

But… (still don't really understand what's happening).
It you save in MSI some settings into profiles (for example +131Mhz GPU / + 50 Mhz Memory), and applying it, then you will overclock your card. Voltage will be set to factory setting (1212 mv in my case) but GPU and memory will then be overclocked.
This setting is getting my card to 1535 / 3557 (using 100% power).
That's my usual setting for mining, achieving 21 MHs with no OC errors on Claymore.




I hope this tutorial will help you getting some precious MHs
If you feel generous, fell free to send me some ether on my wallet : 0xdc7eFDbBE4aFD15c3385d1156b371333550FdDcF

If something is not clear or working, let me a question on this topic, I will try to help you if i can.
If you have an explanation for smi/afterburner behavior i would be pleased to understand what's happening.
If you have other tips for optimize nvidia mining, I would be pleased to used them too.

Bonus : Mine Ethereum Classic

Mining ETC is almost as profitable as mining ETH.
It's very simple to switch on ETC mining.
You just need an ETC wallet/pool. Ethermine provide ETC pool also (eu1-etc.ethermine.org:14444).

You just have to change mining.bat command. Mine is :
One advantage is that you will generate ETC more quicky than ETH and have more frequent payout with ethermine without any fee. (there no fee is you ask to be paid each 1 ETC -or 1 ETH- you mine). But mining 1 ETC is quicker than mining 1 ETH
