"are allrisers working? Whats your PSU?"

All risers works with any of 6 cards as long as i use 4 cards , as soon as i addn 5'th one al go to shit ;p

2x chiftec Polaris 650W PSU Gold, both works, i can connect MB + 4 GPU's to 1'st one or MB + 2 GPU's to 1'st one and other two GPU's from 2'nd PSU all works, i tried dozens of PCIe slots + PSU combos in various setups and al works as long as i use 4 cards

Will try on Monday (got rig installed in office) to re flash, reset it to factory and set up again one by one.

"Above 4G decoding is set to Enabled?"

YES

"Is bios updated? Make sure you to switch onboard vga in bios then connect vga cable to mobo. i have 2 same mobo working no issues with 6 gpu each"

Yes it came with newest bios flashed already. I 1'st assembled MB with cpu, memory and SDD, run it with iGPU, installed system (win 10) and all updates, then started adding cards one by one with all settings in bios made as described it setup guides. it works with 4 cards but wont start with 5'th one added.


"I have this motherboard Cool updating the BIOS solve the problem of 6x GPUS for me, make sure your motherboard BIOS is up to date, BIOS first before gen 1 and 2 switching"

It came with newest bios available, i started installing cards with gen 1 and checked each time in GPUZ and it showed cards are running gen 1.1 at x1 pcie speed

Anyway I ordered other motherboard + CPU set (Asus B365 + Intel G5420) to check if MB is faulty before i can return it to seller.

I tried 1'st and 2'nd gen same result,

Ye set to 6 x 6GB -> 36 GB

But it stops at post screen, and rig restarts, it dint even get to loading system when i plug in 5'th card, i get it put again and all works just fine with 4 cards

I have newest bios avalible for this MB

I run windows but it wont get past post screen, it resets before initializing boot from SSD

With 4 cards it run perfectly, mined for few days already, but as soon i add 5'th card it loops in startup before starting system load.

Hi

I have build my 1'st rig, and i have ecountered problem with ga-h110-d3a motherboard

It works fine with 4 1660s cards in any slot and power configuration, but as soon as i try and to add 5'th card it falls into boot loop and cant even get to bios.

All seting are as described on gigabytes site,

ga-h110-d3a
Pentium G4560
8gb DDR4
6x 1660 super (various models all work in 4 config but in 5 or 6 card config t wont boot)
SATA SSD 120 GB
2x Chiftec 650W gold power supply

I tested various configurations with 4 cards with diferent cards and risers out of 6 i have. I can plug them in any of 6 pci slots and they will work, I can power them from 2 PSU's in any configuration and they will work.

but as soon as i add 5'th card all go into boot loop, it dont even get past post screen and whole machine restarts.

Any help ?
