@daddle    Perhaps i was too fast replying you here.   The reason for using a second GPU is that i will be using it for mining cryptocurrency. Normally, one could not use a GPU of todays standard in a PCI-E x1 slot, as the bandwith would be too low, however when it comes to mining cryptocurrencies, the bandwith is low, and only the memory is used.   What my real question is: how do i make the PC detect the second GPU, which has been connected to the PCI-E x1 thru the riser card. As of now, i have been unsuccessful in making the PC detect the card.   The steps which i have taken so far:   1. checked the Device Manager, but i can only see the first GPU there. 2. I have also run the "Add Device" in the Control Panel, but nothing is showing up. 3. I have also checked BIOS, howerver, since there does not seem to be an option to check the CPU in BIOS, this has also been unsuccessful.   Help would be much appreciated, thank you. ... View more

Hi.   Didnt get any answer but i found it out myself now.   The PSU 550W is not able to mount a second RTX3070 GPU as the number of PCI 6-pin cables are not enough, so i had to buy a new PSU (Corsair 750W RBG) that had space for 4 GPU:s Now, can one use Molex cables for GPU? One can use MOLEX to PCI 6-pin cables, butnot recommended. So better to just get a new PSU. Which is bad considering the motherboard can accept 2 GPUs (1x16-pin PCI-E & 1x1-pin PCI-E)   So please, close the thread, thank you for the help. ... View more
