Just got my RX 5700 reference blower card (XFX, BB special for $290+tax!), showing 49.xx Mh/s in NH, using ClaymoreDual 14 (or 15?). Newest version of NH.

So, not too shabby. Hopefully, it will be supported soon by more than just Claymore.

https://www.reddit.com/r/gpumining/comments/d09421

Found out that currently, one of the few miners that supports the RX 5700 currently, ClaymoreDual, only uses half of the CUs (18 out of 36) on the RX 5700, being that it mostly uses memory bandwidth and not the cores so much.

If the RX 5500, has the same 14Ghz GDDR6, only 128-bit, and half the CUs (22 or 24), it could also be a potent ETH miner.

Well, possibly until ProgPow, which I don't know all that much about yet.
What's the power consumption you're seeing, when mining vs. idle?

WattMan reports peak watts at 155W, was showing 152W yesterday.
Nice. That's solid efficiency at a little over 3W per MH (probably around 3.2?) when factoring in the rest of the system. That would make it 30-40% more power efficient for mining than the old 1060 that lead that stat for a long time. Doesn't quite reach the level of a tweaked Radeon VII that can get down to 2.4W per MH, but the upfront cost is way lower.

Why is NiceHash and Claymore setting DAG#0 (1.0GB) for processing jobs? Is someone trying to hack at the root of the blockchain (DAG#0?).

Perhaps someone can tell me what's going on. When that happens, my mBTC/day soars to like 3x what it's normally at.

Wow Eth almost to $350 again. Interesting times.

Eth at $427 currently. I wonder how the new cards will do in mining once the miner.exes are updated.

Might mine on my Radeon VII for a wee bit to get an idea. No time for it now, but it would be fun to see.

According to whattomine.com, a Radeon VII does about 78 MH/s on ETH, making over $4 a day in revenue. Expected power usage at those optimal settings is about 210W.

With the recent surge, I'm making $12/day, maybe a fraction more. I've got 6x GTX 1660 ti cards (5x of them are in a mining rig running at 80% power limit), and one lone RX 5700 (with the clock reduced to reduce voltage, and the fans ramped up). Plus a few 6C/12T Ryzen CPUs, usually hashing Monero. I refuse to run the mining client "As Admin", as they "suggest", to get higher Monero earnings. Way too much risk. Already, there have been some NH releases flagged with RATs embedded in some of the 3rd-party miners. (And I have had issues with trojans on my LAN for a while now.)

Hmm, mine used to do around 90 MH/s but we'll see. I'll tinker with it later.

I'm not going to bash Ethereum... it's the network that my Coolcoin ERC20 token relies on. Party on, dudes! :)

Hmm, it could be that they are wrong about the hashate, or possibly are underclocking and undervolting the core enough to save power, but also losing some MH/s in doing so.

How much power is the GPU using during mining, and are you guys underclocking and undervolting core?

I can offer some Radeon VII hashrate specs. My main desktop with a watercooled Radeon VII does the following ETH hashrates at the following core clocks and power draw above idle:

800 MHz, 39 MH/s, 84W
1300 MHz, 63 MH/s, 147W
1600 MHz, 78 MH/s, 210W
1900 MHz, 91 MH/s. 283W

I also have a rig in the garage (ventilated) with 6 Radeon VII's tuned to 1500 MHz for 72 MH/s per card, for a total system power of 1130W mining. Efficiency is a little lower there due to higher ambient temps (no A/C) and running the stock air coolers, but underclocked and undervolted with good airflow they all stay around 70C.

Not quite Hermes bag money, but still more than a little "pocket change".

Edit: That's a "surge", which has been, thankfully, happening a bit more frequently.

"normal" estimates are around $200-300 USD / mo.

@VirtualLarry You are mining ethereum with the 1660Ti's?

My RX470/570s are still chugging along. Started again recently though. Few months ago it was too low to justify the power use.

Mostly, I guess. I'm still using NH, it switches between hashing ETH and KAWPOW / RVN, but most of the "surges" are on ETH. Pleasantly surprised to wake up this morning, and find out that the "surge" is still going from last night, and my 24hr average earnings are nearly $16/day. Hope that this continues!

Ethereum is planning to launch staking on the mainnet in a month unless any new critical bugs arise on the testnet. Imminent staking for passive income is providing a lot of upward price pressure right now.
