Experiencing Mining Rig Complication - Any Help Welcome

Hello,

I purchased an ASRock H110 PRO BTC+ (DDR4, 1151 pin), 8 GB Aegis G-Skill DDR4, and intel pentium G4620, 3.7 GHZ, 3MB Cache, LGA1151 CPU from Canada Computers. Made sure to check pins in store as well, all of them were fine. Video Cards are ASUS GTX 1070 DUAL 8GB OC

When I got home I made sure to wait until after installing the CPU to take the cover off the mother board pins. The pins were all OK and the CPU was in properly. Then I Plugged in the CPU fan to motherboard, and installed the RAM. I used powered risers for the video cards and plugged 2 of them into PCI-E slots. Used SATA for a Sandisk Solid State Drive and an LG DVD/CD player. The disk player has windows 10 OEM system builder in it. The player, video cards, and SSD are all plugged into my PSU as well with SATA. Also had an LED power/reset switch, Rii keyboard and mouse.

When I turned on the PSU at this point, my keyboard lit up so i thought that was a good sign. Then I pressed the power switch and the LED light came on, and the CPU fan started working, along with the video cards.

At this point I was excited to plug in my monitor, it needed a HDMI and my mother board, needed a DVI-D plug, Purchased a DVI-D to HDMI 3 FT cable and plugged it in, hoping for the best. But when I plugged it in, the monitor didn’t recognise the motherboard because my monitor just says ‘CHECKING SIGNAL’ for a few seconds, then says HDMI - ENTERING POWER SAVING MODE.

So after all of this I wanted to make sure it wasn’t me just being a bonehead and messing up somewhere (this is my first try at a rig) so I took the motherboard to Canada Computers. They didn’t help much except to take it in the corner of their service area for 5 minutes or so, and the employee brought it back saying that he was able to access the BIOS. I even got the same kind of RAM they were using to try and help.

Unfortunately I am stuck in this position of having all the hardware but being unable to get it going!

If anyone has any advice/ tips/ solutions please msg / post

Thanks for your time

Try using one of the gpu video outputs

The system is probably defaulting to another GPU. As _hill said, you’ll need to plug the cable into the other GPUs until you find one that works. If none do, remove all GPUs except one, that way you can verify that the system is indeed operational.

4

Try using the GPU outputs, and once in bios, set your default display adapter to igpu in bios

also, to my knowledge, HDMI and dvi aren’t necessarily electrically compatible. you’d need a passive/active adapter, not a random cable from china that terminates to the “correct” ends

Dvi and hdmi are compatible depending on the source.

Dvi-i carries both the digital and analog signal
Dvi-a only analog
Dvi-d only digital

Almost all gpu’s have dvi-i out nowadays so dvi to hdmi shouldnt be a problem.

You’re right, I meant to say ‘necessarily compatible’

If the out port on the pc isn’t hdcp compatible it could cause problems, and cheap dvi to hdmi cables can be dubiously connected.

I tried plugging the dvi-d to the GPU and the hdmi to the monitor with the GPU plugged into the motherboard and with the GPU attached to the powered riser adaptors. Still no change to there being no video to monitor. I tried unplugging the GPU completely from the motherboard and plugged in the DVI-D to the motherboard and still no video output!

I thought it could be the cable so i tried it on my PS4 and it worked ! I got it from amazon just about a week ago

The monitor i have is an LG 22MP48 and it only has a D- SUB port and hdmi port. A person on here mentioned trying to plug an HDMI cable from the GPU to the monitor, so I think i will try that.
Tried changing the input on monitor and nothing still

Thanks for all the help, i will keep trying!

I also tried using a ASUS monitor but no go

sounds like a bad board at this point

maybe RMA if that’s available

Going to try a DVI-D to DVI-D cable, see what happens. I think it works because i took it to Canada Computers a few days ago and they said they could get into the bios screen.

Start with just the mobo, cpu and 1 stick of ram. If that boots up start adding hardware 1 by 1. I still suspect its just a bios setting or something.
