You're not being very clear? What's your power supply and how many gpu's are you trying to run? It may not be anything to do with the motherboard and we can't help you unless we know all the specs and of course what you're actually trying to set up the computer for.
Thank you for your reply
Power supply is Fortron Raider Ra750 (I have ready Enermax 1500W Platinum for this rig-can power 5GPU), but i don't think current trouble is in power supply right now
I would like to run 5 GPU, is it possible? I saw post, that some1 is running with 5, saw picture of 4gpu on this board
PC purpose is litecoin mining using windows and cgminer
I am trying to solve why the PCIE1_2 and 1_3 are not running only with one GPU, when i plug it anywhere else, even PCIE1_1 it works
OS System is Win7 PRO x64
RAM 4GB 1600Ghz Kingston
CPU Celeron G1620
Motherboard Gigabyta Z68AP-D3 rev 2.0
What other information you need?
Kindly thank you
