windows 10 only recognises 2 out of 4 gpus.

Hi,
just started mining and I am having some issues with windows recognising more then 2 of my 1070tis. My motherboard is an asus prime h270 plus. I have tried installing the latest drivers on my cards, enabling 4g encoding on my bios, tried different gpu and riser setups and for some reason windows will only recognise 2/4 gpus. Any tips? Thanks.

Did you add the cards one at a time?  Many time you'll run into problems on Windows if you have it try to initialize them all at once.

You could also try one of the Linux distros (like SimpleMining), and see if it sees/uses all 4 GPU's - if it does, then you know it's something in your Windows config, if it doesn't, then you know it's something in your BIOS or related to the cards.

Based on my experience windows 10 is working good and not requires any additional bios adjustments with four cards, anything more then that requires some additional steps
so what should you do.
1. update bios of you mainboard and install updates for windows10
2. insert one card, load windows, install drivers
3. shutdown windows, turn off power, and repeat step 2
4. if everything goes smooth - repeat step 3 until you have installed all your cards
