I finally managed to run 5 cards on the MSI Z170-A PRO.
1. Use an old ide drive.
2. Enable internal graphics in the bios, but use the screen on the pci-e.
3. Set 1 gen pci-e slot in the bios.
4. windows 10.
The internal graphics will fail with code 12, but the 5 other cards will work. If your harddrive is too new, the machine will not boot.
Topic: Z170 chipset can't detect 6GPU???? (Read 2151 times)
just a heads up for everyone
ive flashed 10 gigabyte GA-Z170-Gaming K3 to latest bios F20
9 out 10 work flawlessly with 6 cards, problematic rig needs taking apart and resetting
been stable for 2-3 days now
for anyone with the following board
ASROCK Fatal1ty Z170 Gaming K6
using BIOS 2.8
can run 5 cards by doing the following in the bios
go to advanced mode
and chipset settings
Change PCIE to gen1 on both options
change max TOLUD which is the next option down from the above to 2.5GB
this makes 5 cards work
I have not got round to flashing the bios yet to reassess if can do 6 cards

Main issue with the Z170 chipset is that it is almost totally reliant on the CPU to provide PCI-E lanes - some older chipsets + optimal CPU could provide up to 40 lanes, Z170 seems to be limited to about 28 at MOST with any CPU it works with.
They're just not intended to run more than about 4 video cards, and have to some convoluted stuff to be able to do so.
Onboard sound and LAN do not normally use a PCI-E lane.
Some M.2 SSDs do use a PCI-E lane.

Brilliant explanation. But the question is... could, this M.2, SATA slots or anothers I never going to use, be disabled with the objetive to release some lanes you talking about?
Yes sir, and the same result, I don't know what more I can try...
Try disabling any device you're not using. Sound, LAN, etc... maybe those'll free up resources.
I did with the sound and it didn't work. LAN it's not necessary for the mining software?
Yes sir, and the same result, I don't know what more I can try...
Try updating your BIOS, if doesn't work its probably a problem with your board
I had it updated!
Thanks for the help guys

You should try windows 10 instead, I couldn't get more than 4 cards to run on windows 7 even with 6 gpufix
I'm on windows 10 already tooHave you tried changing the PCI-E to gen1 and increasing the latency?

Guys it is easy.

PS: Do not forget to work application with adminstrator rights otherwise it does not work

The code error i get is different from the 6xGPU_mod fix, anyways I prove running it again in administrator mode and the result is the same.
I have now the 16.9.2 driver ver. Still the same result when I connect the 6 GPU... 3/6 working and the another 3 shows as corrupts
now i use MSI z87 + i7 4770 and 6 GPU but i what change to the new rig for z170 mabo, i heard the z170 can't not detect 6 GPU..and 4GPU maxed it's real??
ASRock H170A-X1 well working with 5 GPU
The ASRock Z170 Pro4S also runs well with 5x GPUs.
I cannot get more than 4 GPUs running on the MSI Z170-A PRO mobo, although it has 6 PCIe slots.

I have a MSI Z170A Krait gaming and only working with 4, when connecting the 5 or 6 one the system can't handle and shows 3 as corrupted:
Code 13 and lack of resources...
Tried almost everything without success

it seems like latest bios updates
will help other people too
I have a MSI SLI z170 board as well
will play with that later this evening
to see if any bios updates help

Gigabyte Z170-GAMING K3 (with last bios) well working with 6 (six) GPU.
I can confirm Gigabyte Z170-GAMING K3 works with 6 cards using latest bios
was setup windows 10 16.9.2 driver
initially set up with 4 cards
then added another 2 cards
windows took about 10 mins to add all the cards
but the driver messed up
so reinstalled 16.9.2
and working fine

try use Linux it will work
some time problem with Windows OS

ASRock H170A-X1 well working with 5 GPU
most people want six
What's limiting the chipset to 4-5 GPUs?
Z170 chipset are not dividing resouses out past 4 gpus
You are lucky if you can get 5 it's rare
6 almost never happens
