Hello all, I found a way to operate 7 gpus with the z87-g45 motherboard. It’s tricky but here’s what I did.
Before proceeding begin with only 1 video card installed in system.
1- set pcie to gen 1 for all PEG in bios
2- first enable igp (integrated onboard gpu) shutdown then plugin your hdmi in the board’s hdmi slot
3- turn on pc and login to windows.
4- the trick is for windows to add gpus one by one and associate the pcie slot for each gpu. Therefore, shut down pc again, install another gpu in a pcie slot and boot up, once in windows confirm it was plugged in device manager then shutdown again.
5- once you get to the 7th gpu you’ll notice that it will not work and your screen will become all colorful at boot up and it will not load to windows.
6- shutdown and then unplug 7th gpu.
*HERES THE IMPORTANT STEP*
7- disconnect just 1 video card completely from any slot except for the 7th slot. Then plug in the 7th gpu (the one that didnt work earlier. Then boot into windows let it recognize the card and then shutdown.
8- now in the bios you need to switch from IGP to PEG. This will disable the onboard graphic. Save and reboot. Allow the system to enter windows without anything displaying on your screen (because your hdmi is still plugged in the onboard hdmi slot. Afterwards press the power button once so it shuts down the system correctly. Once ur system is turned off, remove the hdmi cable and you will need to plug the hdmi into a gpu (preferrably not one which is in the main x16 slot because it will automatically enable crossfire and you will not be able to disable crossfire as it will crash the system everytime. Only work around is to connect the hdmi to a gpu which is not in a full slot...connect it to a gpu which is in a 1x slot.
*IMPORTANT* do not turn on PC just yet, now plug in and connect the initial gpu that we removed from step 7 so now we should have all 7 gpus plugged in into their associated slots and windows is already familiar with each one and their slots
BOOM VOILA, 7 gpus all operating on the z87-g45 motherboard
