I can't keep it between 20-40 degrees. I have a heater to warm it up but then it gets too warm. So turn on the fans and it gets too cold. Do these not have a auto thermostat? Am I suppose to sit here 24 / 7 adjusting fans?

So I have 8 RX 580 GPU

On cudominer I was getting 140-168 mh/s. I tried over clocking but only 7 out of 8 gpu would ever get 100% utilisation. I am currently trying claymore but 2 cards are only doing 9mh/s

I’ve downloaded MSI burner. I tried messing around with some settings but it didn’t seem to affect the hash rate? Do I need to download something else

Disabled that but hasn’t made any difference. Great appreciate any help

I changed some of those bios setting but I don’t seem to have all of those settings.

I think it’s something to do with not having a PCI 8 to change to Gen2. I unplugged the 8th and all 7 were fine. So I used the cables from 7th to number 8 and it loaded up 7 gpu 100%. I added a power supply and it went back to the same issue 7 at 100% and 8th at 0%

It has 13 pci spaces. The 8th card works for a few seconds then doesn’t. I haven’t changed anything apart from changing gpu to compute mode.

I’ve got 7 out of 8 RX 580 8GB GPU working on Cudominer. But the others all worked by changing from auto to Gen1 or Gen2. I only have pci up to 7. So I can’t change the pci 8 to gen1. Where is it? The computer does find the gpu but the utilisation is 0%

Ok I’ve disabled parallel ports serial ports and audio. I’ve changed the pci to Gen1.

It seems to be working. I’ll leave the rig running tonight. Fingers crossed!

I’ve tried various guides but I don’t think I’ve modified the bios? Any ideas on what I can do?

Last night. Tried Phoenix program. After about 20 mins it stopped. The fans have stopped and the program had closed. I’m currently trying cudominer with just 2 GPUs....

All purchased new within a month.

The latest offline went with one fan out of 4 running the rest all had stopped. The computer this time had crashed so had to force close it. The monitor had cudominer this time running. I thought I had turned off cudominer and started Phoenix. But I do keep trying both.

Having trouble starting the motherboard. I use a screwdriver to get it to turn on but it won’t turn on at the moment. But tomor I’ll test out the 1750

It worked! For 2 hours .... then went offline.

Power settings are setup to never turn off. The virtual memory was set initial min 48000 And max 48000. All 4 gpu are setup to compute mode.

I’ll try find some other versions of Furmark. Otherwise do you offer paid support? With any desk

Furmark has an error when I try and install it.

I’ve got a video of the Phoenix running. I’m just uploading it so I can post a link

Wow thank you I’ll do it tomor evening when the kids are in bed. I changed the gpu to the compute and tried Cudo miner. I tried it with 3 GPU and it seems to be working but I’ll test it over night.

Nope soon as 3 gpu it crashes. Within minutes. Downloaded and used the two programs suggested.

Any other ideas?

I’ve got a screen shot of the Phoenix when it crashed. Any help?

Saw something about no cuda driver accepted shares 0 incorrect shares 0.00%

Use:
win 10 pro - Already using
latest AMD drivers 20.8.1 - Already done
windows swap file 40 gb - what is a swap file?

MSI Afteburner - I'll download tonight

PhoenixMiner 5.1c - I'll download tonight

It literally crashes straight away at the moment. I've only connected 1 power cable to max 2 gpu. Even 3 gpu crashes it - so would that suggest more software issue?

Thanks for the advice

I can run 2 GPU RX 580. But soon as I increase it the Cudo miner crashes! They crash within 30 mins. Would it make a difference to swap to Linux ?

Cut it down to 2 gpu and change to igpu. It worked.

So I’ll increase to 4 cards?

ASROCK H110 Pro
8 x Sapphire RX 580
120gb SSD
Corsair 1200w power supply

My PCI risers only seem to have a sata connection.

My Corsair needs
2 x connection to motherboard
8 x gpu connection but split in half as one cable does two
8 x pci riser connection but split in half as one cable does two
1 x motherboard power
