2 GPU rig problem!!!!! Help!!!!

[chianghiong]

hi guy, I am using nicehash legacy.

My rig always restart if I set my afterburner power limit to 90, now I am running 80. Got fews times after I install the Gigabypte PSU (power limit 90), I saw 3 of the GPU stop working after few seconds

Also I am using NH to mine, so if I turn on Lyra2 my rig also will hang and restart it self, now I only can only Equihash and Neoscrypt.

May i know what is the problem?

My rig spec:
-Asus EX-B250-V7 x 1
-Intel G4400, 3.3 GHZ , 3MB Cache, LGA1151 ( BX80662G4400)
-Corsair ForceGT 120GB SSD x 1
-Corsair HX1200 x 1
-Gigabyte Xtreme Gaming 1200w x 1
-MSI GeForce GTX 1080ti x 6
-Corsair DDR4 2400MHz 4GB x 1

I connect Corsair HX1200 to motherboard,SSD, CPU, 3 riser and 3 GPU, and Gigabyte Xtreme Gaming 1200w to 3 riser and 3 GPU.

MSI Afterburner Setting For 2 PSU IF I set the power limit to 90, rig will restart it self or power on the 2nd PSU will trip/cut off.
Power Limit - 80
Temp. Limit - 80
Core Clock - +95
Memory Clock - +600
Fan Speed - 80

MSI Afterburner Setting For 1 PSU( work fine)
Power Limit - 100
Temp. Limit - 80
Core Clock - +95
Memory Clock - +600
Fan Speed - 80

Anyone have this problem?

**Update
Today reformat my rig and add new ram to 8 gb, and new SSD. And the problem still the same

Problem Solved
For restart - change riser and SATA cable port
For trip - PSU failure

could be 4gigs of ram in windows.

What are your overclock settings for both core and memory clock? One possible reason why your rig keeps restarting is because the GPUs are failing which could be due to bad overclock settings. Try dialing them down a bit.

4 GB ram should work fine for a simple mining rig. Im running 13 GPU rigs with 4GB RAM and with mixed rx VEGAs and 1070s and they work fine.

Are you using Win10? Maybe forget to increase a virtual memory or can possible a bit wrong when installing two PSUs simultaneously utilizing a tool relay such add2PSU or a paper clip.

Did you check the blue screen code for crashes?

I doubt it, he doesn't state blue screens in the first post.

@OP,

Try to play with your clocks, it always depend on which algo you want to mine with it

here is the good read for different clocks for mining different algos

Lyra2v2 is wierd .... i tried to mine on that with 4 different miners (excavator, trpuvots couple of versions, nanashi ... ) ... everyone had its own settings on gpu ... crashing and bad respons from pools by every miner ...
if you mean Lyra2z then tdp of 80%+ will crash pc everytime coz its needed max 50 of tdp and OC will be almost 0 coz lyra2z is lowest power algo of all time

the rest is ok i have similar config on my rigs (maybe just make virtual memory 32g minimum and 64g maximum)

-Gigabyte Xtreme Gaming 1200w x 1
-MSI GeForce GTX 1080ti x 6

you're feeding each 1080ti with 200w, this is a nobrainer.

You don't need over 70% power limit anyways, it makes little to no difference.

[NetopyrMan]

yes i totaly missed that you have only 1200w psu ...
stock tdp for 1080ti is 250w...if you have MSI its much more

edit: just buy another PSU for (like 800) for 3 cards and risers and the rest put on that 1200w .... you will need PSU with enough 8pins ofc

He has two PSUs, 1200 each, 3 cards on each.

be careful when reading. @OP uses two PSUs to power a mining rig. I think it has no problem with power consumption or the like.

I connect Corsair HX1200 to motherboard,SSD, CPU, 3 riser and 3 GPU, and Gigabyte Xtreme Gaming 1200w to 3 riser and 3 GPU.
