Here to pick your brains! (Mining rig issue)

[nick1803]

My Rig:

Asus Z270-A
4gb Ballistics DDR4
120GB Adata SSD
1000 Watt EVGA G2 Gold
Intel Celeron CPU
3x EVGA 6GB 1060
3x Zotac 3GB 1060



When I set it all up one of my 1060's would not hold a steady voltage, it was fluctuating like crazy.  It caused my system to reboot itself once every 6 hours or so.  Oh well, 5 cards worked great.  I yanked it out and RMA'd it, never had any other stability issues.

Got the new EVGA 1060 GB in today, get it all plugged in on the riser and fire it up.  The fan spins up but windows detects nothing.  Weird.  I reset all my connections, still nothing.  Tried a new VGA PSU power cable, nothing.  Tried a different VGA power port in my PSU, nothing.  I thought maybe this card was bad too, then I stuck it on a known working PCI-E riser and windows saw it and its currently mining.

I took the known working card from that other PCI-E riser and stuck it on the one I initially tried to put this new card on...and that one was undetected in windows as well.  So both GPU's work, I got that far. 

I thought well maybe its the PCI port on my mobo...switched the riser connector to the last open slot and still nothing, so I doubt its that.  So I'm left with a bad riser...I think.  I don't have a spare to test with unfortunately. 

Am I overlooking something?  Any ideas?  Thanks!

This section is for BTC/ASIC only. You might want to move this thread to the ALT mining section. In the bottom
left corner of YOUR thread there is an option to move it. You will get all of the answers you are looking for
in that section. Goodluck!!!

I ran in to some TOLUD issues early on that wouldn't pick up my last 3 GPU's on my first 1060 rig?  I had to set the BIOS to increase the TOLUD.. if you search on the forums there's some info have you come across that yet?

[nick1803]

Yes when I had my initial 2 1060's (3rd was being RMA's), I got my 3 Zotac 3GB in and when I slapped them in I was having issues detecting them so I followed a youtube guide and changed a bunch of Bios settings and Wallah!  All 5 GPU's detected.

I don't think its my bios since I already see 5 GPU's.  Is there a particular setting for my Asus you would like me to check out?  Thanks!

Just the TOLUD but if you've done that already and the other cards are showing up it's a bit of a mystery.. I would be thinking it's a bad riser as well.. do you have one card on the MOBO itself?  If not could you put one in to the board and then use the spare riser to test?  Or just swap the riser with another?

With how the mobo is screwed onto this frame I have its not possible to mount a card directly into the PCI slot, darn it

[nick1803]

I do have a new riser on its way to me, Amazon says it will be here Saturday

[nick1803]

Well this is odd.

For the heck of it, I took one PCI-E riser from a working card and plugged it into both open ports on my mobo...it refused to boot into windows each time. 

Think its the motherboard that's no good?  This is so frustrating

Not sure how you're connecting the gpus but if you have all 6 connected try to leave the x16 slot unused and populate the other 6 slots.
This board is known to behave like that.
Try that and see if it works.

In the video below BBT has the same setup as you.
Fast forward to 11min 50 sec to listen in on how to connect.

Side note: The video in general shows you how to get your rig setup and is a good watch if you have the time.

Probably a motherboard issue.

If i was you i would go pick up a Asrock H110 Pro BTC+ or Asus B250 Mining Expert, and i'd bet your problems would be solved!

Yeah, I have the x16 populated.  If I use the others but not the x16, which card will the monitor run off of?

Thanks for the reply

[nick1803]

NVM, got the monitor to post.

So I put 6 cards in each of the x1 slots...they all worked except for the card with the suspect riser still, no effect.  

At this point I'm just not sure if its the mobo or the riser...or something else

Run your monitor off the integrated graphics built into the CPU.

It's unlikely a riser issue, since you've had a GPU running with the same riser. It's probably a motherboard limitation. Like PCI-E resources running out. Some motherboards only support so many GPUs.

[nick1803]

Correction, I've never had a GPU work with this particular riser.  I've tried two gpus

[Tristan1337]

Oh well then if that's the case, i guess you should try another riser before you do anything.

Better to buy more than what you need, because you always run into issues with risers. 

[nick1803]

Update - it was the riser.  All 6 GPU's humming along

[Tristan1337]

Good to know you got it working.

Most risers are built very cheap, so they are usually one of the first things to go.

Happy mining!

Now watch the $$ roll in glad you got it working!
