Need HELP with New rig build using h110 pro btc running SMOS

[BigA3723]

Longtime lurker and finally made account cause I’m desperate for help. I just finished assembling a 6 gpu rig and can’t get it to start. A quick list of parts

H110 pro btc MoBo
8g(4g x 2) dimm
i3 cpu
6 - 1070 ti zotac amp extreme
2400w server psu from parallel miner


So I have built computers before and pretty confident everything on hardware side was installed correct. When I turned on, I don’t get anything on screen. For simplicity I flashed SMos on a usb and it looks like it’s booting but nothing on screen. After trying everything, if I unplug all the gpu cards, it boots off usb, but gives like 3 screens of text and then stops. When I plug gpu back in, the monitor I’m using says signal not supported, I’m using onboard dvi, to div to hdmi converter to hdmi in on monitor. Also have tried plugging into gpu hdmi or dvi and with no signal or signal not supported.

When I have all gpu off and plug video to onboard and begins the smos boot up, I don’t see any options to enter bios. Can I take a new MoBo with not update graphics files and run the SMOs from start? I didn’t extract the SMos zip file before flashing  to usb because it didn’t say to in directions, should I have extracted it first?

How do I get into bios? Does a MoBo without any hard drives or memory sticks still be able to boot into bios? I’ve been at it for hours and last thing I can think of is trying with a windows boot usb and see how that works, if not, will see if I get a dvi to vga cable and see if  the message “not supported mode” I get from monitor with gpu installed is the issue.


Bottom line, if I put everything together correctly, should I be able to have a smos usb as the only thing I do on software side and have it work or do I need to install some drivers first? I guess if smos cant fully run, then the gpu don’t have drivers and that why they don’t work? Any help is appreciated.

you have to look for the hot key combination to boot up in your bios and start pressing it before the system starts
you can surely boot into bios without even any secondary storage plugged in
boot in bios change pcie lane speed to x1
enable 4g decoding
only then your smos will start booting with your gpus

You should be able to see your bios settings or a disk boot failure error if your PC components installed correctly without an OS, mainboards has typical "press type key ' in order to get into bios, most probably a F12, F10, F1, or Del.

You may try the windows boot if that would make you feel confident enough to troubleshoot, then go back to SMOS when everything's fine, set aside your GPU's, make your OS worked first, then do the rest.

Ty both for response, after using another hdmi and another tv, I was able to get a boot using a windows install usb but once I get past 2 cards it shows a message when I turn on “plug 4pin power to Mobo” which is the two Molex connectors that give extra powr to PCI-E and both are definitely plugged in and powered directly from psu.

I think this may be a driver issue but the only way I can proceed using windows route is to install it, but my SATA plugs aren’t recognizing either a 120gb ssd drive or a cd/dvd player, it’s like my 4 SATA plugs are dead. I can install a M.2 ssd and get it recognized on board, but it’s 16gb and not big enough to install windows so that doesn’t help. I was thinking of installing windows, then updating all the drivers, then I can boot from smos usb after everything is working, but can get SATA to recognize. I tried different SATA cables and made sure it’s activated in bios, any ideas what I can do?

I can flash another bios to a usb and install through bios, should I try that? Should I try smos again on usb with just 2 cards to get it loaded?
