Asus z270-p / 2x 1070 3x 1080ti / Cant get it going PLEASE HELP... I havnt sleeped 2 days :/

Hello everyone, im new in the mining.

I have asus z270-p and 2x 1070 asus rog and 3x 1080TI gygabyte aorus extreme.

I have stabilized 4 GPU’s but 5 cant… 4G decoding is one, i’ve flashed latest mobo bios 0808 version. PCIe speed tried with GEN1 and GEN2 too…
Windows 10 64 bit pro, 1703 version.

Im installing windows with 1 Gpu conected and then im conecting them separately.

I’ve managed that in device manager i can see all 5 GPUs without problem marks but when i start miner with 5 gpu most of time 4 gpus are working properly and one of them 1070 or 1080ti (in the multiple times of tries) is giving lesser sols and after 1-2 minut crashed and in most of case im getting windows error TRD failure…

They are conected with pcie risers ver 6 with molex power.

Please someone give me some tips… Im not lazy one and im reading before asking but no solutions worked for me …

Is your power supply enough for that many GPUs

yes i think... I use separate server psu for gpus 2400W it can handle 3x power that is currently conected ...
