Ethereum GPU mining?

[ozzy702]

Hey larry, you should be able to set clocks and voltages in the miner itself, at least with phoenix and claymore. Also, for 5700XT's, you shouldnt need to set a power limit, just decrease the cvddc and core clocks in the miner. The miner should also be able to set them per card. At around 1200 - 1300MHz, you may also be able to undervolt a bit further. Perhaps just a bit below .8V. What hashrates are reported on the 5700XT's? Also are you touch memclocks at all?

^ this. I never play with the power limit on AMD stuff. I just figure out where each card is happy and set it manually there. I bet he can cut power consumption and corresponding heat quite a bit. Sounds like maybe his settings were only applied to one GPU. Those 5700XTs are really nice cards once they are dialed in. It's unfortunate that the 6000 series are so expensive and have such tiny bus's.

F it, I decided to run this foolishness while it’s cold out ... I have electric heat anyway and office was 54 degrees this morning before I turned it on. Got my 3080 running Phoenix on ethermine pool and paying out to coinbase ... super easy setup, took 15 minutes. Power limit to 60% and RAM to 2675 MHz and I get 101 MH/s at 225 W. Not much of a heater I guess.

Do you have a Coinbase wallet that you are using? Coinbase changes your ethereum address pretty often.

I appreciate the tip. Just looked it up and apparently the coinbase generated address will be valid forever: https://help.coinbase.com/en/coinba...data-privacy/why-did-my-wallet-address-change

I will figure out a more permanent wallet solution after the first payout

What operating system are you guys using for your mining rigs? I'm currently using Windows but wondering if I am leaving performance on the table by not using something based of Linux.

I'm using a bunch of Windows installations. Although I'm interested in what others are doing.

225W will be enough to raise temperature in a typical office room by 2-4 degrees.

225W will be enough to raise temperature in a typical office room by 2-4 degrees.

Remember, it's using more than that, based on your use-case scenario. I am measuring approximately 185W at the wall with my digital meter while mining on Win 10 (5700XT/5600X). The card is drawing approximately 102W of that. That's just with the miner open. I was surprised how much power a browser window 'consumes'. Opening something like Steam or Spotify bumps it up by over 40W. I still have to figure out what the monitor is also using. I have it shut off after 10min, so likely not much, but it still counts towards cost.

I figured my power cost per day is 185W X 24hr/day/1000 = 4.44 kWh x 0.145/kWh = $0.64 CAD per day ($0.49 USD). In my case my system is shut down when I'm not using it, which is usually 23 out of 24 hours per day on average, so I have to take the entire power draw into account.

There's also wear and tear on components, although that is likely not much as PC parts seem to be a lot more reliable than cars for instance. I'm going to add another $0.10 per day for that, but maybe it's more? This is with Nicehash. I'm going to switch to lolminer and see if that makes any difference (to profit and power usage). I'm making about $3.91 CAD/day avg profit for the last 2 days.

Wear and tear on components is something you might want to keep track of, but it's always pretty marginal. Unless you're pushing the bleeding edge of overclocks or treat them like absolute crap with their environment, even with mining you're still much more likely to have the card become obsolete before it wears out. If you're strictly using it for mining though you can easily fold that into what you're calculating for depreciation on the gear.

I'm keeping it in the 52C range (1150 RPM) with as low voltages and fan speeds as is possible. I had forgotten about the memory temperatures though and suspect it was causing my intermittent AMD driver 'timeouts' where it would set it back to auto (@1860MHz). I had to check GPU z to get the memory temps. I bumped the fan curve up a bit to about 30% and the temps dropped by about 7C on the memory (87C now).

I don't usually sell my cards, I just hand them to my kids, so I guess getting the card paid for makes that a bit easier to swallow. It bugs me a bit when my youngest never touches his PC that I built for him, but I guess it's better that he be on the snowboard hill instead of sitting in front of a PC! I won't be putting any more GPU's in his system though.

Pretty impressed so far with lolminer on my 5700XT. I get a little less hashrate (53 vs 53.8) than Nicehash, but my power draw is down to 97W from 102-103W. I also like how it displays more info (memory temp) and gives you your MH/s/W with the updated info. It's showing mine right now at 0.542 MH/s/W, which is a nice bump from 0.52 with Nicehash. I'm also not getting any rejected or stale shares. With Nicehash I was getting about 0.7%, which I've read is low (less than 1%), but obviously cuts into efficiency.

I'm getting a 3070 on Saturday and will have a decision to make whether to sell the 5700XT (for around $800+ CAD judging by EBay prices) or build another PC from my spare parts and mine on that 24/7 (i5 4670, H81 or Z97 MB). The only thing that may be iffy is the OCZ 600w PSU that I would be using. It's an older one that works fine. Would it be an issue? I don't want to have to buy another PSU.

I don't want to have to install Windows on it either (I don't have any more licenses), so I'd likely try Linux. All of this depends on the price of ETH staying high however. Thoughts? Sell it or keep it?

Do you have 240V and/or are able to put in a 240V outlet? Server power supplies work great as secondary mining supplies.

No 240V. I could probably put one in (I did in the garage when I built my last house), but that would cost just as much as a new PSU. I guess I can just try it and see how it goes. As long as nothing starts on fire, I'm ok using the one I have. I am going to set the PC up and see what kind of power it's drawing and how consistent it is.

 

[Fallengod]

Not to side track but, I am trying to decide if it might be interesting to give mining a try. Never mined or anything before and have zero experience. I am going to ask a quick handful of questions here.

I live in so-Cal so my electricity is $0.22/kWh, so with my current rig with a ryzen 5 5600x, 16GB mem with gtx 1080 8gb. Is that even worth mining on? I figured the first logical step would be to try mining before getting serious about it. I would probably want to build a computer just for that and I cant find any RTX 3060ti/3070's for a reasonable price anyways, so I should probably get my feet wet first.

What would be an optimal computer to build just for mining? Some old i5 system or something? AMD/Intel? Does it matter? Buy some used parts off the forum for a cheap mining rig?

Good software to use starting mining? I really need some help here. Ive heard nicehash, but also that there are a plethora of mining programs that are more efficient to use and I am probably looking for efficiency.

Anyways, any help from some pros.

Before you go building dedicated mining rigs, you can mine on what you have. Unless you have "sensitive" documents on there, then it might be worthwhile to build dedicated rig(s).
Nicehash and Cudominer are "one-click" miners, but you can get an ethereum wallet and start pool-mining directly too.

Anything you recommend to use? Ive heard some say phoenixminer, someone above said lolminer, and various others. Any idea on a wallet to use? I have no clue about either.

Looking for highest hashrate and least electricity used if thats possible...

I'm a rookie here too, but I've done a lot of research and have now used Nicehash and lolminer. Nicehash is supposedly 'one-click', but I found it more complicated to use than lolminer, and it was a chore having to allow 20+ exceptions in Windows Defender. Defender had no issue with the download and install of lolminer for some reason, but Nicehash made it go haywire.

It's probably tougher figuring out which miner/pool/wallet to choose than anything else. There are very few sites friendly to noobs I find, other than reddit surprisingly. I've also got some pretty thorough responses in the comment sections of videos.

You also need to tweak your settings for your video card in Afterburner. Your card according to WhattoMine is good for 34 MH/s at 170W. You can likely get that power usage down quite a bit though with Afterburner. I generally watch videos by Son of a Tech and Hash Raptor. Mining Chamber is also good.

You would have to use Phoenixminer (or something like that) as lolminer is supposedly only 'optimized' for AMD. I use Brave browser with Metamask as a wallet, and Ethermine for the pool. You could go through the hassle of setting up a hardware/paper wallet I suppose, but with the small amounts I'm mining (and you will be too), I'm not going to bother. You can also just use Chrome/Metamask, but I wanted to try Brave out.

This video should get you going:

He uses lolminer, but you can just substitute Phoenixminer 5.5c - get it from the Bitcointalk forum here:

Oh, you said it was a 1080?

So youre saying dont use lolminer for nvidia? Or does it really matter.

I've read that it does matter. Others may know more about that though. I'd just use Phoenixminer for that card if I were you. When I get my 3070 up and running in a few days, I'll be using PM. I'll probably continue using lolminer on the 5700XT though, unless I decide to just sell it and cash out while I still can.

Does anyone here know the deal with stale shares? I know what they are, but I'm getting sometimes up to 6% per hour when I check the dashboard in Ethermine, but when I look in lolminer, it doesn't show any. Is that Ethermine dashboard just bugged, or is lolminer? Is there really an acceptable level of stale shares? They do seem to go down when I turn up the memory clock a bit.

Are you connecting to the closest Ethermine server? What's your ping to it? Is your miner hard wired? I typically have 0-1% on Ethermine, never had more than that.
