Hello everyone!

This is a good topic. I was thinking building the same device with Raspberry Pi. So far no enough time but I found easy solution with some TP-Link Smart Plug with energy usage monitoring. I have two rigs which are stable and this works. For many rigs this solution is good.

I suspect that at some point the suppliers will cope with the high demand. Currently the prices are sky rocketing and even if your setup is not optimized you get good profit.

Hello everyone,

I was thinking of building second rig with RX 470 or RX 570 (or RX 480/580), but for two weeks straight I cannot find store which has them in stock here in Bulgaria. Some suppliers told me that the shipments for the next 2 months were already preordered. Is the situation same in the countries where you live?

The profitablility right now is good and there should be high demand for these cards but this should not be a suprise for the ones who sell them. Was it the same year ago?

I am not in a hurry but having to wait months to get cards is confusing me. Please share your thoughts.

Hello,

Can someone share good bios rom SAPPHIRE RX 480 NITRO+ for mining zcash. I could not find any roms for that GPU besides ones optimized for ethereum. Thanks in advance

Plug the one with zero hashrate to a monitor. Hope that helps.

Of course you can mine zec with these cards. They are the ones that I am using to mine zec. You will get around 300 h/s with stock settings and Claymore miner. With may stable overclock settings I get almost 320 h/s per card.

I am glad that this also worked fo you. I know how nice it feels to have all cards running without any errors after assembling the rig 

Not sure if I understand what you are asking. Where can I check this number?

Check out my thread for similar problem: https://bitcointalk.org/index.php?topic=1768064.msg17656449#msg17656449

It worked for me. Hope you find something useful.

Different algoritms consume different power. I have 5 Sapphire Nitro+ cards and when mining zcash they draw 800 watts from the wall. Monero mining draws around 700 watts (maybe less). System consumes around 100 watts and each card consumes around 120-150 watts depending on coin mined. My cards are undervolted with moderate overclock.

Hello,
Do you have exactly the same configuration?

That was so simple and it worked just like that. Thanks big time guys!

I played with chipset settings, but with zero result. Even started thinking I bought the wrong motherboard. Now everything works

Thanks again!

Do you know a good OC settings for these GPUs? I tried few but nothing stable.

Hello,

I am trying to build my first rig, but I ran into some problems I cannot explain.

When I tried to plug five SAPPHIRE NITRO+ RADEON RX 480 8G GPUs using USB risers with voltage control on ASRock B250 Pro4 motherboard the following error was observed in Device Manager:


In that case only 2 GPUs are recognised and work correctly. There are no problems when 4 GPUs are plugged. I tried to re-flash the BIOS and tweak some settings with no result. As far as I know the motherboard should be fully capable of running 5 GPUs. Please help me because I am using only 4 out of 5 GPUs and it drives me crazy.

I am using ADATA SSD drive and Celeron CPU if that matters. Also everything is running on Windows 10 (not activated).

Thank you in advance!
