Topic: My rig freezes when mining eth (Read 310 times)
I got 87-97w per card, how could it be the power supply deficiency is the reason why my rig was freezing, I also tried to change risers, usb cable, riser power cable etc, but i have the same problem, by the way I already use my cards a year ago, but Im only using it for lessthan 5 months then I was decided to stop and dissembling my rigs.
Its very strange that it would freeze because it was pulling too much power. I think on stock voltage those GPUs pull maybe ~150-160Watts each, so 6 of them is around 1000kw. The PSU should still be able to handle it because if I recall the G2 1300W PSU was single rail. So it didn't matter which way it was delivering power.
If you got a quality PSU you can run it at 80% load most of the time and not get any issues. I remember back in the Antminer S2 days, those pulled 1000Watts out of the box and the PSU included was a 1000Watt PSU. And basically a large percentage of them ended up failing since they ran at 100% load non-stop but there was also tons that ran fine at 100% load for years. Hence 80% load on a quality PSU shouldn't be an issue.

Maybe it is something about voltage, this PSU used to handle larger loads, even 1200w. I also tried with a newer PSU I have, an NXZT Hale90 1200w, and it kept freezing as well.

So what's the culprit here? Looks like you have limited power supply, if reducing the voltage works then it's the power, I'm glad you are able to figure things out, can you share the exact watt that your GPUs are pulling? Thanks
Memory: 2100@875mV
Core: 1050@875mV
31.2mh and 97w
I have 6 identical gpu, three of them turn unstable after 3 hours with that config, so I have reduce them its memory frecuency to 2050 reducing its performance to 30.7mh and 94w.
I don't think its your PSU. If you want to eliminate your PSU as the culprit just run the miner with reduced intensity, basically run it at 50% and see if it runs then. It will use less power and you can see if its your issue or not.
Try what I suggested and get your motherboard manual and find out about the available lanes on your PCIe slots.

The problem was solved when I downvolted from 1150mV to 950mV, now my rig is perfectly capable of mine with 6 gpu.
Now I am just reducing voltage to reduce costs, so I downvolted to 875 which is the value I have found on some settings that other users recommended.

And psu can now handle the load.
as a rule of thumb 60% on an atx works well 24/7/365. and 1300 x .60 = 680 watts.

Just realized that 1300 x.6 is 780 watts
Anyway, I kept changing the voltage down to 875mV for both core and memory and it is still stable.
How much is it safe to downvolt?, I don't dare to put any lower value.

Do you think that the problem of freezing rig is not a pSU related problem? In my experience I've cleaned my mobo with cleaners then I also tried the randomly change my riser slot to my pcie but the problem remains.

That is also my problem right now, one of my rig has 12 rx 570 4gb and I am currently using a mining expert motherboard, I powerup my rig with 1000w corsair and 850w fsp, 7gpu for my corsair 1000w and 5 for the psf 850w, I noticed that in the first run of my mining apps, the hashrate was good but after a few minutes, my hash power decrease and some of my gpu turn to zero hashrate, and today everytime i run the miner it was frozen. I did almost of all of the troubleshooting method, changing the riser, the usb cable, etc. Now, my question is, is my gpu enough to power my rig? I saw also in the miner that my rig only consuming 1098w.
no try
five on the 1000 watt
four on the 850 watt
see if they run overnight.
a lot of atx psu age. a year or two into operation they cant do it.
if 5 and 4 work over night
try 6 and 5
remember to downvolt.
My rig brings me a headache, sometimes the zeroed hash gpu will randomly rotated, after I've change the riser, usb cable and run the miner it will took around 3-4 hours then it will give the zeroed hashrate again in one of my gpu, then my rig started to freeze.
The only thing I can think of is that your motherboard is pretty much sharing some PCIe lanes and why you are getting this issue when you add the 5th GPU. I had some motherboard like this in the past, and wasted so much time trying to figure out what was wrong but basically according to the owners manual there were some shared lanes on the PCIe slots.
Basically you can have 2 PCIe slots but you might only be able to use 1 at a time even if you are using risers and running it at 1x. Go to your motherboards manufacteure website and download the owners manual and see if there are any shared lanes.

No, first thing is reducing voltage. No need to edit bios for that.
Thanks man!, I undervolted the gpus core form 1150mV to 950mV, now it is running stable at 700w according to my kill-a-watt
As a rule of thumb never use GPUZ to save roms. Use the bios flashing utility itself.
Good to know, thanks.

Too late
I flashed 1 gpu using ubermix 3.1 straps (it is a samsung memory)
After that MB won't boot with HDMI connected to it, however it is still being recongnized in windows and capable to mine.
I flashed back its original BIOS, however the display was not fixed.
It is still on warranty so I will return the card.
EDIT:
Apparently the backed up ROM extracted from gpu-z of that card was invalid, and the strap modification I did it on that ROM. Good thing is, I did a backup of all ROM so I could reestablish it and its working

Okay, it started to fail again, with 50Gb virtual memory, it started to throw Video TDR failures.
I also changed the PSU for another similar one with no luck.
It was an improvement however, I can mine with 5 gpu for some hours without getting my rig freeze/restarted
With 6 GPU it instantly gets frozen.
I tried to modify straps with Claymore automatic feature, however it throws Video TDR failure when starting.
I will MOD bios to change straps and reduce voltage with AMD drivers, it my final guess.

You need at minimum 6*8GB of virtual memory ...
Thanks that was the issue. I remember using 16gb for my old 6x 4gb gpu rig so I though 32gb would work
And mining @stock is just a joke, stock voltage is just burning your rig ...
I tried MSI afterburner, it just simply does not work, I will try claymore auto oc or MOD the bios
i would suggest you get a 15-20 dollar kwatt meter and see what you are pulling at the meter.
If you are over 1100 watts and have been using that psu for a long time at say 900 watts the psu may not be up to the task. so pull a gpu to see how it runs.

Add way more virtual memory. What do you need drive space for anyway.
More than 32Gb??? How much? 64Gb? I don't know if there is space in disk disk for that

virtual memory?
32000 mbclock to high?
Gpus untouched, mining at stockpower supply is maxed?
Don't know what that means
you are only mining with a single 4 gig ram id would increase the virtual memory in windows
Done it and tried more ram
virtual memory?
clock to high?
power supply is maxed?

I have a mining rig with:
With 4gpu it works completely stable, after adding the fifth one, no matter which one, it freezes after 2/3 min.
At first it threw Video TDR blue screen failures before restarting, then started to just freeze. A couple of times, my MB bios CMO got cleared.
I have above 4G enabled, pcie latency 96, gen 2/3.
Latest Adrenaline drivers, and gpu stock BIOS (never oc)
I am using Claymore v15.0 with the suggested env vars set
Windows 10 PRO updated version
Ive tried:
Any ideas?
- MSI Z270 Gaming Plus
- EVGA Supernova G2 1300W
- 6 Rx 570 8G
- 4Gb RAM
