EDIT - SOLVED! The solution was to go into the device manager, click view and show hidden devices, and uninstall the integrated GPU. Claymore and Phoenix both booted right up. Thanks u/asdf4455 !
I believe this has something to do with an update Windows has, because I have the exact same mb/cpu/ram/hd setup on another rig and this was not an issue. So if you're fresh installing a new rig, this is the likely culprit!
So I've built a few rigs, never come across this problem. A board I had was having trouble so I bought a new one and now have 6 cards on a fresh Windows install for this rig. Everything looks good. But for some reason, Phoenix and Claymore will not start.
No errors. Here is what Claymore is doing with wallet/rig info changed:
C:Usersrig4DesktopClaymore>EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal wallet.rig -epsw x
╔════════════════════════════════════════════════════════════════╗ ║ Claymore's Dual ETH + DCR/SC/LBC/PASC GPU Miner v10.2 ║ ╚════════════════════════════════════════════════════════════════╝
ETH: 1 pool is specified Main Ethereum pool is us1.ethermine.org:4444 DCR: 0 pool is specified
C:Usersrig4DesktopClaymore>PAUSE Press any key to continue . . .
Phoenixminer with standard wallet:
No CUDA driver found
C:Usersrig4DesktopPhoenixMiner_2.9e>pause Press any key to continue . . .
Anyone have any ideas? I'm pretty lost on this one.
Ethereum miner with OpenCL, CUDA and stratum support
Ethminer is an Ethash GPU mining worker: with ethminer you can mine every coin which relies on an Ethash Proof of Work thus including Ethereum, Ethereum Classic, Metaverse, Musicoin, Ellaism, Pirl, Expanse and others. This is the actively maintained version of ethminer. It originates from cpp-ethereum project (where GPU mining has been discontinued) and builds on the improvements made in Genoil's fork. See FAQ for more details.
Standalone executables for Linux, macOS and Windows Desene online dublate in romana. are provided inthe Releases section.Download an archive for your operating system and unpack the content to a placeaccessible from command line. The ethminer is ready to go.

The ethminer is a command line program. This means you launch it eitherfrom a Windows command prompt or Linux console, or create shortcuts topredefined command lines using a Linux Bash script or Windows batch/cmd file.For a full list of available command, please run:

The new WDDM 2.x driver on Windows 10 uses a different way of addressing the GPU. This is good for a lot of things, but not for ETH mining.
Because of the GDDR5X memory, which can't be fully utilized for ETH mining (yet).
Only GCN 1.0 GPUs (78x0, 79x0, 270, 280), but in a different way. You'll see that on each new epoch (30K blocks), the hashrate will go down a little bit.
Not really, your VRAM must be above the DAG size (Currently about 2.15 GB.) to get best performance. Without it severe hash loss will occur.
The default parameters are fine in most scenario's (CUDA). For OpenCL it varies a bit more. Just play around with the numbers and use powers of 2. GPU's like powers of 2.
--cuda-parallel-hash
flag do?@davilizh made improvements to the CUDA kernel hashing process and added this flag to allow changing the number of tasks it runs in parallel. These improvements were optimised for GTX 1060 GPUs which saw a large increase in hashrate, GTX 1070 and GTX 1080/Ti GPUs saw some, but less, improvement. The default value is 4 (which does not need to be set with the flag) and in most cases this will provide the best performance.
Genoil's fork was the original source of this version, but as Genoil is no longer consistently maintaining that fork it became almost impossible for developers to get new code merged there. In the interests of progressing development without waiting for reviews this fork should be considered the active one and Genoil's as legacy code.
No, use geth, the go program made for ethereum by ethereum.
There is an environment var CUDA_DEVICE_ORDER
which tells the Nvidia CUDA driver how to enumerates the graphic cards.The following values are valid:
FASTEST_FIRST
(Default) - causes CUDA to guess which device is fastest using a simple heuristic.PCI_BUS_ID
- orders devices by PCI bus ID in ascending order.To prevent some unwanted changes in the order of your CUDA devices you might set the environment variable to PCI_BUS_ID
.This can be done with one of the 2 ways:
Linux:
/etc/environment
file and add a line CUDA_DEVICE_ORDER=PCI_BUS_ID
export CUDA_DEVICE_ORDER=PCI_BUS_ID
Windows:
setting environment windows control panel
using your favorite search engine)set CUDA_DEVICE_ORDER=PCI_BUS_ID
or setx CUDA_DEVICE_ORDER PCI_BUS_ID
. For more info about set
see here, for more info about setx
see hereYou have to upgrade your Nvidia drivers. On Linux, install nvidia-396
package or newer.

Hi,
Thank you for posting your query on Microsoft Community.
I understand that msvcp120.dll is missing from the computer. We will assist you to resolve the issue.
I suggest you to perform SFC scan and check if it helps to resolve the issue.
System File Checker (SFC) is a utility in Microsoft Windows that allows users to scan for and restore corruptions in Windows system files. Perform System File Check (SFC), and then check if this fixes the issue.
Press the Windows button + X on your keyboard, a mini dialogue box will appear.
2. Choose Command Prompt (Admin). You must run the command prompt in Administrator level.
3. On the command prompt type sfc /scannow and hit enter.
4. If everything went okay and no errors were found, restart your computer and see if the issue re-occurs.
Hope the information helps. Let us know if you need further assistance. We will be happy to help.
Thank you.

Hi,
Thank you for the update.
I suggest you to run DISM and check if it helps.
The DISM or System Update Readiness tool may help you to fix some Windows corruption errors.
If the issue persists, I suggest you to download the latest ISO of Windows 10 and perform automatic repair.
Steps to perform repair:
a) Insert the installation DVD or USB and boot Windows from it.
b) In the ‘Windows setup’ page select the language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.
c) Click on ‘Repair your computer’ and select ‘Troubleshoot’.
d) Click on ‘Advanced options’ and select ‘Automatic Repair’ and select the operating system.
Let us know if you need further assistance. We will be happy to help.
Thank you.

The dll in question belongs to the Microsoft Visual Studio 2013 redistributable packages, you simply need to download and install that. I had this problem because I only installed the x64 version of MVS2013.
My error isn't from a visual studio, its from CNEXT.exe. and nothing is fixing this.

HannTheftAudio, you don't understand. Your software, being it 'CNEXT.exe' or something else, requires you to install Visual Studio 2013 redistributable packages (which are a small bunch of library files) because your software was built with Visual Studio 2013.
You can download the required package here:
By the way, Visual Studio is a software development platform which helps people create software.
