Rig Building : No boot!

[owocki]

Hi there everyone,

I built a mining rig for mining ETH/Zcash with the following specs:

> 6x GTX 1070
> Power Supply:
> 2x 1000W EVGA SuperNOVA PLATINUM
> RAM:
> 2x 4GB Kingston Ram
> CPU:
> Intel Celeron G1840
> Motherboard:
> ASRock H81 Pro BTC
> Risers:
> 2x PCI-E PCI Express 1x to 16x
> 3x PCI-E 1X to 16X
> 1x PCI-E Micro PCI Express 16X
> OS / SSD:
> ethOS (operating system)
> Misc:
> Add2PSU Adapter (used to connect both power supplies together
> Power Button

> FLOW 6.1 GPU Mining Rig Open Air Frame Computer Case Chassis with 6 USB Risers - Ethereum ETH Bitcoin BTC

I can't seem to get any output to my monitor from this device when I turn it on.  I can get the CPU fan to turn on and the GPU fan to turn on.  But I can't seem to get the 1070's LEDs to actually turn on either.

Here's a picture of my motherboard

Any thoughts, folks?  Is there a way to test each part individually to find out if it is DOA?

Here is my TODO list for debugging currently.  Anything I should add?

> # todos
> - Create ubuntu install disk
> - disable onboard GPU per https://forum.z.cash/t/problems-booting-asrock-h81-pro-btc-no-post-9-out-of-10-starts/6785
> - Does the socket of my motherboard match CPU? (Chris suggestion)

> # evan (hardware friend) convo
> - Try DVI, not HDMI as a default
> - make sure this CPU is tested and known to work
> - you might be DOA (either CPU or motherboard)
> - Go to Frys Electronics or Best Buy for parts

Strip it down to a minimal system with IGPU. If that works try with one GPU, then another etc.

Tried that.  No luck, even with the IGPU

when u wont get an bios alert beep or led code its an cpu issue

all other problems must give out an beep error or an led error code out only when it comes to cpu failure it wont do anythink.

try just ur cpu with another minimal system

Thanks for the response.

The led does blink, but only blinks once.  The motherboard doesnt have an alert beep on it..  Where do you recommend i look in order to understand led error codes?  There is nothing about that in the motherboard manual.

99% faulty MB. You have to RMA.

Any way I can prove it's a faulty mobo?  I dont want to pay a restocking fee!

Does it get past post at all?

Gets stuck at boot (no post)-  it is either a mobo issue or pcie riser issue.  Put a known good pcie riser on the main x16 slot and it will get past post and boot.  You can probably repair the riser, I had an issue with a riser where there was a thin solder bridge on the back between 2 of the slot pins.  Repaired that riser like 3 months ago and it still works today, was a total bitch to figure out being my first experience with it.

Gets past post, starts to boot then goes black screen(windows issue)-  This is probably not the issue from what you are describing.
Go into bios and tell it to use onboard only, then boot into system.  Go to device manager and find where the os loaded a driver for onboard and disable it, revert settings in bios to auto, reboot and you should be good.

1. I'm not sure.  The CPU fan and GPU fan power on.  But no other signs of live.

2. I dont think the issue is a PCIE riser.  I tried putting the card directly on the mobo, but no luck.

3. I'd love to go into the BIOS, but I can't seem to get any signs of life from the screen.

New motherboard overnighted and arriving today.  Hopefully that solves the issue..

Dont use LGA 1151 chipset for your mining rigs , work only with 4 GPU
