Title: amd+nvidia
Post by: CroBoy12 on November 28, 2017, 12:19:35 AM
I have 3 cards and i want them all put on same pc.

gtx 780
gtx 1050ti
rx 570

I read everywhere and some people done it but no explanation or tutorial how to do it. Can someone help me telling me how to do it or atleast put some link to some tutorial?

Thank you.

You mean what currency can you mine? Bitcoingold is a GPU mining

You can do it by simply installing both the NVIDIA cards first then followed by the AMD.
Here is a step by step instruction to make things clear:

1. Plug the NVIDIA cards into your computer
2. Install the NVIDIA drivers and make sure your NVIDIA cards are running fine
3. Shutdown computer
4. Plug the AMD card into your computer
5. Install the AMD drivers

You don't have to do it in two steps, could just install all cards into the PC, power it on and install the drivers. Nothing's achieved by shutting down the PC between driver installations.

Running both 780 and 1050 ti though could pose some problems. I didn't personally try those 2 cards together myself, and 780 isn't that old so it'll probably work.. but I tried to run gtx 1060 with an old nvidia gt 210 once (wanted to use gtx 1060 only for mining and gt 210 for video output), and it didn't work. The drivers just didn't want to install for both of them, gt 210 was not recognized as an nvidia card and I was only getting 640*480 res. Both cards worked just fine separately, but not together.

I use PCI passthrough into virtual machines.

What kind of problems should i expect?

Example, i have only 1 monitor, if i connect nvidia+monitor, what about amd?
Can i install nvidia+amd drivers on same pc? And how? Simply downloading drivers from official sites or i install it from device manager?
Do i need VirtualBox or similar to run it?

Better connect the monitor to amd because you probably won't be able to tune the card otherwise (adjust clocks/voltages/fans — polaris cards need something plugged in into them, at least in my experience with mixed "nvidia+amd" rigs).

Just download the drivers and use their installers. Nothing extraordinary there.

Why on earth would you need virtualbox? :D It can't do anything for you, you just run your cards natively in the OS of your choice (preferably win 10 as it seems to be the least problematic OS for mining in general).

I have run AMD and Nvidia cards on the same Windows 10 Pro v1703 rig without issues. Just be sure to run DDU in safe mode to remove ALL the installed GFX drivers and disable the Windows automatic driver install. After shutdown, I connect the AMD cards and install the AMD blockchain drivers. I also install an AMD card in the primary x16 PCI-E slot and connect the monitor or dummy plug to that card.

https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Blockchain-Compute-Release-Notes.aspx

You also need to run the pixel patcher after the driver install with RX 470/480 and RX 570 cards that have a modded Bios to disable the driver Bios signature check, or you will have a code 43 error in Windows Device Manager.

https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher

Then I shutdown and connect the Nvidia cards and install the drivers. I've had the best results with the 385.41 drivers on Windows 10. Newer drivers aren't as good for mining in my experience.

http://www.nvidia.com/download/driverResults.aspx/123219/en-us

In the Windows 10 Pro Group Policy Editor you can keep Windows Update from updating the the drivers on it's own.

gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

The only problems i've had is when I move cards around to different PCI-E slots. The Windows registry keeps an identifier for every card installed in a PCI-E slot and if I move an AMD card to a slot where a Nvidia card was installed, sometimes it will prevent the driver from loading. Always run DDU in safe mode to remove the drivers before installing any cards.

You are going to have many driver problems. Forget it.

The only possible problem he could have is to run 780 and 1050 ti with the drivers from the same installer. But since nvidia site suggests 388.31 when either gtx 780 or gtx 1050 ti is selected, he's not likely to have any issues.

The 3 cards should run together, but ANY mixed AMD+NVidia rig is going to have noticeably worse stability than an unmixed rig - which is the primary driving force behind my current "rationalization" process, getting the Nvidia cards OFF my FM2 based machines.

I disagree. Thanks to mixed mining I can optimise better and the rig is perfectly stable. Taking about an amateur 6 card rig 3x970 3x570

For both the 1050 to and the 780 the optimal drivers for mining on are probably the 373.06 version.


 And no, mixed rigs are NOT as stable as non-mixed rigs - never have been, and unless Nvidia Intel and AMD all move to one unified graphics arch (which will probably never happen for Nvidia to the other 2) mixed rigs will CONTINUE to be less stable.
 They can, in some cases, be SORT OF stable at times, if you happen to hit a pairing that work together better than normal - but never AS stable as not mixing.

 Sometimes the drivers conflict, and you also get the fun of getting hit with whatever bugs/issues/etc are in BOTH drivers as opposed to only getting hit with the bugs/issues/etc from ONE set of drivers.


 "Better optimization" isn't a stability issue, positive OR negative.

Is it even worth usinng the 780 for mining? I think the power would cost you more than the hash rate it produces or am I wrong about this?


Title: Re: amd+nvidia

780 profitability should be in the ballpark of the 970 - they were both 28 nm, just the Maxwell generation had some optimization.

I have been running mine uninterrupted for months. Love mining ether + monero because it balances the power so well :)
It is curious, but for some coins, the hash for a 120 USD card is nearly the same as the one for a 240 USD card.
