Title: Asus P5K Pro does not detect 3rd GFX card Post by: tadpole on April 19, 2014, 08:48:38 PM I updated my gaming rig and started using my old Asus P5K Pro motherboard (p-35 north bridge) as a dedicated mining rig. I've individually tested all the risers and gpu's I bought and I know for sure they are not the problem. My motherboard will not detect a third card. I've tried tweaking a few things in the bios but had no luck. Does anyone know if there is a way to get the third (and eventualy 6th) card to be detected? If not, can anyone recommend a cheap reliable mobo that will run 6 or more gpu's? I'll be purchasing one tomorrow if i can't get what i have working. I've let this gpu sit to long not making me any money.
Thanks in advance. Title: Re: Asus P5K Pro does not detect 3rd GFX card Post by: jazarja on May 09, 2014, 12:26:26 AM you need to use pci-e 1x jumper cable. Working properly with my ASUS P5K Duluxe

I have a mining rig with a p35 with a core2 quad and had to run all 1x to 16x risers on all slot to make all the cards work. I tried to run 4 1x to 16x and one 16x to 16x, only worked for 2 cards.
