you need 2 PSU or at least 1800W or more, i am using 4 1800W PSU for 10 2080Ti card now.
I don’t have a mix of cards on the same rig 
I haven’t tried, but what about running two grin-miner processes?? (if it even works, you’ll probably need to clone another instance of the repo to allow you to use two different grin-miner.toml files to allocate the devices accordingly).
I run amd rx 580 with grin gold miner and nvidia gtx 1060 on bminer.
its all on windows 7 OS, attempted ubuntu first wasting 3 days learning why physical device ID was fucked up like shit and couldnt make sense of any and no experienced old wise cunts could lend any help coz they fat and dumb and i hope they choke on biscuit crumbs…
so… go win 7 - go different scripts for different card by setting your config file to appoint the correct physical ID for said card. peace, hit me up if u need the link to windows updates for dot net to work properly.
but you are doing C29 mining?
hey guys
having the same issue like Rabinovitch with my rtx 2080ti…
i have linux 18.04 on the oracle virtual machine running
i downloaded the grin miner and setup everything for the grinmint pool on c31 algo
when i start the miner i only see this:
i read somewhere that i can not use my monitor?!? how am i going to setup everything on windows 10 if i can not use my monitor?!?
can anyone help please!
thanks
this setup might only work if you will be able to passthrough your RTX to VM (pcie passthrough).
- you have to connect your primary display to the “onboard” graphics card (from intel cpu)
- the motherboard and cpu must support vt-d
- you have to enable the vt-x & vt-d in motherboard bios
- the virtualisation software must support pcie passthrough as well, afaik virtualbox doesn’t support it, you have to check microsoft hyper-v or vmware
so, there is lot of work to get this working. i would consider to “reverse” your setup, run linux as a primary OS and put windows in VM.
ya ya only 29, unsure as what to buy for 31 in regards to value. i dont know y 31 would be different if the card is compatible? lol
I never used grinmint. I use f2pool. I had the issue before as well. I made a mistake with the password of the stratum.
Did you check the GPU ID for the RTX and GTX?
You can check the ID by using nvidia -smi
Because you need to place GTX ID cards to and add more lines example;
[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_gtx_31”
[mining.miner_plugin_config.parameters]
device = 0 (this is the device ID)
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024
[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_gtx_31”
[mining.miner_plugin_config.parameters]
device = 1
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024
[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_gtx_31”
[mining.miner_plugin_config.parameters]
device = 2
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024
[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_gtx_31”
[mining.miner_plugin_config.parameters]
device = 3
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024
Below is the command for your RTX GPU
[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_rtx_31”
[mining.miner_plugin_config.parameters]
device = 4
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024
Hi @tromp and fellow grin miners:
Has anyone tried mining c29/ c31 with an NVIDIA P102/P104? Results?
I have been testing a V100 with c31. So far so good. I am interested in optimizing for c32 and could use help from an expert on the algorithms. I will make a DGX station available for this purpose.
that‘s would be great, thanks for this!
Were you able to get C32 to find working solutions?
My question is actually when the miner for c32 would be out.
yeh grinmint is getting slower, assuming its due to huge market share?
thanks for the answers… i am going to install ubuntu on my computer and try it without the VM
that should be the best way i think
It’s obviously the best way…
works with dual boot finally…
so how do i can start the mining without using gui?
Set a proper runlevel first:
sudo systemctl set-default multi-user.target
then reboot your rig. Set it to ‘graphical.target’ to revert things back.
Then use ‘nano’ editor to modify your grin-miner.toml file. Use Internet for more details, these steps has been described thousand times already.
One note: there is much more convenient to start the miner via ‘screen’ program.
You can just create the file /etc/rc.local and make it executable, then put this content in it:
#!/bin/sh
screen -dmS grinminer /home/rabinovitch/grin-miner-v1.0.2/grin-miner
Save it, change the rights with ‘chmod +x /etc/rc.local’, restart the rig and you should see that miner has been automatically started. To see this, use ‘sudo screen -r’ command.
thanks… i will try it… can not someone in gods name make a video tutorial for this 
there are like a 1000 vids on how to mine c29 but not a single one for c31… weird
