Hello,

Running PhoenixMiner / Windows 10 with 12 Nvidia Cards is running fine, but when adding the 13th Card, I got an "Out of Memory" Error. Adding extra RAM or enlarging Swap File doesn't help. Using different RTX and GTX Card, always the same.

Is this a hard limit, or is there a way to work around this?

Thanks for help!

Its definitely difficult to get 12+ GPUs working which is why most don't try but I think 13 should be possible. You say you increased the swap file without being specific - how big is the swap file? I would have it at 90GB-100GB for 13GPUS. I run 11 on a ASROCK H110 pro btc+ and recall going from 10 to 11 gpus and eventually got it working after increasing the swap file from 64GB to 80GB. If you already have a huge swap file you might check that your swapfile disk isn't running out of space (did that to myself once too).

Currently I am using 80GB for 12 GPU, but even increasing to 100GB does not help with the 13th in the first place.

Is somebody running the 13th GPU under Windows? Which settings for swap files and how much RAM do you use?

I was running 12 with only 60gb page file with no issues(pre 4gb max) Unfortunately I only have the Biostar MB so Cannot test a 13th for you.

During the 4gb rundown I switched to Ubuntu to get the most out of them.

Now I am using that rig for alt coins and have issues depending on coin / miner I have to sometimes go back to Ubuntu to get it to work(Haven for example) but it does not seem to be the page file as under windows no more than 2 cards will initialize(using TRM/Haven but works SRBMiner/Haven). I have not been able to figure out why either. Not sure if this helps you:)
