I have an asrock z170 extreme4 which has 6 pcie slots, so far I can only use 5 slots (that is by changing the TOLUD (Top Of Low Usable Dram) setting from default to 2.5 GB in the BIOS)

the question is does anyone have experience using this mother board and managed to use all six pcie slots for the GPU

I don't think many people use this board with so many cards.
For most systems, the BIOS should be set to CSM Disable, and Above 4 G decoding to enable, if this board even has that, but maybe try by moving one of the 5 cards, to the empty slot, or use only 1 card, and first test if all slots are working individually
But the baord is not designed for mining
