Hello,
Because my electricity price/kwh went up and the price is bad , i am no longer profitable mining and i want to sell my rigs.
The rigs are as follows:

4 rigs with :6 x RX 580 8GB Nistro+(Sapphire)
3 rigs with :6 x RX 580 8GB SE(Sapphire)
1 rig with :6 x RX 580 8GB Pulse
1 rig with :GTX 1060 6GB(MSI Gaming)

The rest of the components are the same for all the rigs:

MB: Gigabyte h110 D3A
PSU: EVGA Supernova Gold 1300 W
SSD: 120 Gb Kingston
Ram: Corsair 4gb ,2133 Mhz
Risers:Wazney 008S, 60CM
CPU:Celeron Kaby Lake , 2.9GHZ

On/off button, aluminium frames etc.

Hashrate for the RX rigs is between 180 and 183 and for the GTX rig us 144.
Also RX rigs where undervolted so RX rigs are using 900 w.
Rigs run under windows 10 with awesome miner.

Gpus are still under warranty for 15 more months, so are the other components.
The rigs ran for 3 months in an air conditioned room.
I am located in eastern Europe.

If anybody is interested feel free to contact me for more details and price.

Here are some photos of all of them together:

Hi so i have found finally the real problem.

One of the GPUS in the rig is not "broken" because it can work fine in gaming and other applications but it cannot sustain the constant heat/pressure of the mining process so after a while it crashes and brings the whole rig down.I suspect that this GPU has a lower quality than the other 5 gpus in the rig.

I changed this GPU and everything started to work fine.

Problem SolveD!

Ok will do that.

Do you know anything about the errors in the screenshots though?

L.E: I added the options you mentioned but still the problem persists

From https://bitcointalk.org/index.php?topic=4547448.0

...

I got some screenshots here showing the randomness of this weird problem.
In the first Screenshot i am on stock bios and Only 2 gpus generate dag and hash, while on the next 2 screenshots i am on modded bios for mining, here all 6 gpus generate dag and hash.
Thing is it is random, it can happen in reverse aswell, or other times only 3 gpus don't hash or only 1.It has no specfic rule.It is random.

Here it is the first screenshot on stock bios with 4 gpus not generating DAG and hashing with 0.All 6 GPUS are starting up but only 2 generate DAG, so 4 GPUS will hash with 0.

Second pair of screenshots.This is after restart and switching to moded bios.All 6 Gpus start up and all generate dag successfully.

Halp please !

Hi thanks for answer

I checked with HWinfo and i have no errors.

What are eres and lidag options for?

So after a crazy amount of:

Switching to a new PSU, new Motherboard,changed driver version for chipset, switched ram and CPU,windows uefi mode, Reinstalled different version of windows 10, applied a registry blocker,Adjusted page file to 50 GB, Switched other risers, and power cable,Unistalled Afterburner, Made settings in wattman,Reinstalled afterburner, set GPU bios to stock for 1,2,3,4,5,6 Gpus in this order, than back to mining bios,switched riser power cables again, changed again using molex instead of sata and other stuff -  i still did not find the problem.

What i can tell you is what i have observed so far.Sometimes miner starts with 6 gpus with full hash and runs ok,sometimes it doesn't.Usually when it doesn't it is when i pulled the power cable out after shut down and let miner like that for 10-15 minutes(no ideea why).When it doesn't it can give 0 hash for 1-3 GPUS like in the image below.


VERY WEIRD AND I GUESS HERE LIES THE SOLUTION FOR WHO UNDERSTANDS WHY IT IS HAPPENING

When miner starts with 0 hash for some of the GPUs, i have observed that said GPUS with 0 hashrate do not generate theyr DAG.So if i will have 0 hash on gpu 4 5 6 they didn't generate theyr dag at the beginning of the mining process and after a while they "will not respond" while GPUs 1,2,3 generated DAG succesfully at the beginning of mining process and will not give that error.So after the miner works like this for a couple of minutes , it gives the error "Threads not responding, restarting" for all the GPUS that had 0 Hashrate and basically stops mining process for the whole system, this keeps repeating in a loop, with the gpus having 0 hashrate beeing always the same.

I added a Screenshot with this error.

Sometimes all 6 gpus complete theyr dags succesfully and miner mines ok, but most of the time 1-3 GPUS do not generate DAGS and soon the respective error follows.

What is this?Does anybody know?It is making me crazy !
Please help !

I use a h110 d3a MB with a minig mode.As soon as i enable mining mode, 4G is automatically enabled, but i will check bios again to see if everything is ok.
I have GPT partition.
I need to check point 3.

Thanks!

1.Changed psu, not from here
2.Maybe -  need to try
3.Nope
4.If nothing on the hardware part works, i will need to try a fresh reinstall.
5.How so?I only use onboard vga when i connect the rig to a monitor.Other than that i connect to it with remmote desktop.

Yes i def. need to change riser sata cable, i didn't do that yet.If its from the cable it would be an easy fix.Other connections seem fine otherwise.

It is not a heating problem, i have 10 cm between gpus and rigs are in an air conditioned room.

I did switch to standard bios on GPUS and i have the same problem.I will change the riser sata cable, i didn't try that yet.Thank you !

was listed today on cryptobridge, price is bad.
Not profitable to mine at this moment, only for speculation if price goes up in the future, you can make many coins fast, total hashrate is low right now.

So i managed to switch the PSU this weekend, but the problem is not from here.Any other suggestions?

thank you , will try that in the following days and will let you know !

So i have a problem that i can't seem to be able to fix for awhile now

I have a rig with 6 x rx 580 nitro+ 8gb, dual core celeron, 4 gb ram, PSU EVGA 1300 w and a h110 d3a MB.This rig can only function with 5 gpus atm because as soon as i connect the 6th gpu , 2 other gpus along with the last connected gpu mine with 0, so i have 3 gpus that mine with 0.Soon after this happens i get blue screen, and restart.

I operate on windows 10, GPUS are all undervolted with -70 mv, core and memory 1090 and 2090.

I tried switching riser 2 times, switching gpu power cable , switching pci slot order, riser power cable and taking each gpu one at a time.

What i found out is the following.Gpu is fine and can mine ok when it is alone, all gpus are working actually so no problem from here.Risers are ok aswell(slot,cable and pci jack), power cable also.
Everything is ok when i add 2nd,3rd and 4th GPU.

Problem comes up when i add the 5th gpu this time from the opposite part of the rig, so that as soon as mining starts after dag is finished i can see that 2 or 3 cards mine with 0 , and soon after , error screen and restart.
What is this?I never encountered this problem before, i have 3 other rigs exactly like this and they all work fine and stable.
PSU problem?MB problem?

Salut,

Eu cred ca o sa merg !Chiar sunt curios cum o sa fie , va fi primul meu crypto summit

Stii ceva mai multe detalii despre eveniment?

I have the bat file exactly like the one on ethermine.I put it here but without my wallet address.

I also used -allpools 1 and it gives the same error
This is my Bat file:


setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100

setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool eu1.ethermine.org:4444 -ewal here is my adress.Batman -epsw x

and as pc componets i have:
Msi geforce 1060 6gb
Msi motherboard H110M PRO-D
Memory Patriot Signature, 4GB DDR4, 2133MHz, CL15

Hei guys can someone help me with this problem please?
