If you're running NewPac you need to use:

./cgminer -o stratum+tcp://solo.ckpool.org:3333 -u Your_BTC_Address -p x --gekko-newpac-freq 500 --suggest-diff 128 --api-listen --api-allow W:127.0.0.1

How many GPU rigs do you run?

Honestly, I'm good with the ballpark numbers. I have no desire to do this. lol

In SMOS. The rig is closer to 570 at the wall, SMOS shows the rig around 545. I'm not sure how to measure each card independently @ the wall without running each card solo to get a sampling over a set time period.

The first two are the 2 fan model using the 8 and 6 pin power connectors, but both the Red Devil and Nitro+ are 3 fan models using 2x 8 pin connectors.

So, theoretically the Red Devil and the Nitro+ should be pulling close to the same power, but instead, the Red Devil is closer to the 2 fan model in power draw.

What's weird is that I'm running 3 PowerColor and 1 Sapphire RX5700XT and noticed that the power draw on the sapphire is a lot less than the PowerColor.

1. PowerColor Radeon™ RX 5700 XT 8GB GDDR6 (base model) - 110W
2. PowerColor Radeon™ RX 5700 XT 8GB GDDR6 (base model) - 109W (fan continually ramps up 100% - temp only @ 49C)
3. PowerColor Red Devil Radeon™ RX 5700 XT 8GB GDDR6 - 112W
4. SAPPHIRE NITRO+ Radeon RX 5700 XT 8GB GDDR6 - 95W

It seems like buying Sapphire cards would theoretically be more power efficient based on my small data sampling.

4 pin fan for GPU:

But I would think you would need the appropriate fan for your card.

Thanks, so far I've been stable for almost 4 hours without a restart using the last settings that I posted and pushing the Power Stage to 7.

***UPDATE***

Stable at 25 hours.

Keep in mind that these settings are stable on a straight Ethereum pool.

3 PowerColor RX 5700 XT running at:
Core MHz: 1300
Mem MHz: 915
Core Undervolt: 800
Power Stage: 4

I'm going to try dropping the Mem MHz to 900...

***UPDATE***

I've dropped my settings to the following and have crashed 3 times in 30 minutes:

Core MHz: 1300
Mem MHz: 900
Core Undervolt: 800
Power Stage: 4

That definitely caused some issues after running about a minute, I guess NiceHash isn't in my future until they come out with the newer NHOS.

Do your AMD cards get a lot of restarts in SMOS against Nice Hash? I'm at 17 restarts today using SMOS with Phoenix, I can't get TeamRed Miner to work against NiceHash (using the proper BTC address), but it works great against Ethereum with ETH address.

Yes, I only get errors on Nice Hash, I can run against Ethermine for days with no issues.

Doh... I literally knew that! lol

This keeps freezing my my server:

-a ethash -o stratum+tcp://daggerhashimoto.usa-new.nicehash.com:3353 -u 0xdd484cddd2ad58d2f562db2973ce1f87b59826e4.$rigName -p x --eth_stratum_mode=nicehash --api_listen --watchdog_script=/root/utils/force_reboot.sh

Do you get a lot of these errors? My server has like 11 restarts from when I started this a few hours ago.

Thanks, I will try this later tonight. I'm currently using TeamRedMiner.

I was running NHOS for a few weeks on an old ASRock H81 Pro R2.0 and Intel 3250 with (4) 5700XT and I ended up burning out 1 GPU and couldn't get the OS to function properly after the fact.

I also couldn't get NHOS to function with an ASUS TUF X570 Gaming PLUS WIFI System Board. The OS loaded and said that the cards were hashing, but just showed "pending" when I looked at the web console on Nice Hash.

I would like to add that I ended up going to Simple Miner OS after reading this thread and like it. Still have to figure out how to hash on Nice Hash... I'm currently running on Ethermine.

Do you use NHOS or connect from SMOS?

Thanks, for the info. Currently, I'm using PowerColor 5700XT's. I just replaced one of my dead PowerColors with a Red Devil yesterday under warranty from Micro Center.

Phil,

Do you suggest waiting for the release/sale of the AMD 6000 series or going with the new NVIDIA cards to anyone looking to purchase new cards?
