Cryptocoin Mining?

[Torn Mind]

Hmm, Doge is truly a special or odd coin. I tried my best to avoid it after the initial rush thinking it was in exchange rate hell, and now I feel like a fool. Time to finally direct my hashing power back towards it....

Yup. Watching Coinye plummet because of the spineless devs makes Doge, the joke coin, look legitimate.

Edit:

lol. look @ 0daycoins.

 

[SunnyD]

Its foolish to sell doges before the block reward halving tbh.

lol. There are so many Dogecoins in circulation that if you think that the block reward halving is going to make any difference, I've got a beach in death valley to sell you.

I've been mining for fun (and miniscule profit) for a couple of weeks. I seem to have the bugs sorted out and my 280x can hit 280k pretty steady if the rest of the computer is idle. With a bunch of stuff open but no video going it's in the 660 - 675 range.

But when I try to play a youtube video, things get laggy and hashrate drops down to the 400kh/s range.

I'm thinking of getting a 270 to power my system and monitors for day to day work while the 280x mines. Then at night, putting the 270 to work mining as well.

I welcome any suggestions on whether that is a valid strategy and anything I need to be mindful of when setting that up, how to configure my bat files, etc. (I'm still a noob at this, but learning quickly).

Thanks.

hehe... that's how it starts. By Spring you will have 2, 2x290X's rigs mining 24/7. Why would you even need a 270? My main computers I use for actual work are a laptop and my main computer which just has a cheapo dual monitor Nvida card in it. I find that working on a rig that mines is just annoying to deal with, constantly having to shut it off, etc.

As far as my rigs are setup. I just load windows 7 (i just leave it unregistered), latest catalyst drivers, some extra security apps, notepad++ and cgminer. I'd get a kill-a-watt to determine exactly how much you are actually pulling.

Currently looking at setting up one of the rigs up with Linux/USB as I'd like manage through ssh/bash instead of RDP. RDP does mess up the cgminer instance on occasion.

I thought I heard of using the integrated graphics, I've been meaning to try it out and see if it's not laggy when at full power. My 290x's can handle higher intensities than the last gen cards for some reason but I turn it down or off if using the cards for something else.

 

[Kosmic1]

Kloc, my thinking on the 270 was that I could use it for work, rendering, watching videos, etc while the 280 mines during the day. Then at night running a second .bat for the 270 so that it can put its 350 (or whatever) kh/s to work while I sleep.

I would suggest not buying the 270. here are 2 options I would prefer:

1) Adjust your mining to avoid lagginess, so that when you want to use your computer for Youtube etc., you easily reduce the intensity to enable the card to have more resources available. I'd suggest simply making a copy of your existing batch file for cgminer, and then just name the copy "no lag" or something, and simply reduce the intensity value stored in that batch file. So when you normally mine, use the original batch. When you want to use the computer, quit that instance of cgminer, and immediately launch the "no lag" version.

2) Buy a super super cheap video card, or use integrated. Getting a 270 is hard to justify because it's not really going to pay for itself (probably), so you are just stuck with that added expense for not really much benefit. If you are really interested in mining, maybe consider another card you can crossfire with your existing miner, so you can double the mining speed, while still enjoying the ability to crossfire for gaming (or other non-mining tasks).

I think with option 1, you'll continue mining nearly as efficiently as before, so you will barely lose any money, and so you'll come out far ahead compared to buying another video card.

Cgwatcher can automate this for you. It can turn off the primary card for mining while you are using the system, or it can turn down the intensity to a usable level. Cgwatcher uses conf files, and it has its own conf editor built in (I don't like the batch file method).

My primary home system has dual 7950's. One of them is at intensity 20 all the time, and the primary card is at 18 unless I'm using the machine, where cgwatcher drops the intensity to 15. I also run an HTPC machine with a 7770 where cgwatcher totally shuts down mining if it detects activity.

I run off the iGPU, but you wont get sensor readings from CCC or other software, the cards function fine but you cannot tweak them for fanspeed, clockspeed or vcore.

Where is the iGPU guide again? I want to start using mine, but have no clue how to start. I control all my card settings through cg miner anyway, so I would definitely prefer to use iGPU.

Can I switch from iGPU to one of the graphics cards if I decide to run a game?

You cannot tweak it at all when you run off the iGPU.. well I cannot get it to tweak. Its all stock only.

I got it to work by: Setting integrated GPU in bios as primary (with hdmi cable connected to iGPU). Install intel drivers. Reboot into bios, set PCIE primary, reboot with hdmi plug in R290, boot into windows, install latest Catalyst drivers. Disable crossfire, disable CCC overclocking option. Reboot pc into bios, put iGPU as primary, put hdmi cable into iGPU, boot into windows and the Intel drivers activate with the iGPU driving the display.

CCC will work but it won't read any R290 sensors nor will afterburner. But you can mine with it at I19 or 20 and system is still very responsive due to running on Intel.

Once all that is done, there's an option to run R290 as primary in bios, once you boot into windows, if you pull hdmi cable and put it into iGPU, system goes blank for about 5s, then the iGPU kicks in and becomes primary. You can reverse this as well, and switch the hdmi cable back into the R290 and it becomes primary again, for gaming purposes.

I get about 300kH/s on each 7870 at stock settings, so it wouldn't be worth it to me

But by stock only do you mean the last good known VBIOS settings or stock only as in the settings that the card defaults to after a fresh install?

 

[Silverforce11]

Stock as in whatever is in it's bios. So you can tweak it if you modify the bios.

I've been on both sides of the dedicated mining rig vs a productivity/entertainment/mining rig. From what you wrote I'd suggest you just take it to the logical conclusion and figure out how to build the most efficient dedicated mining rig you can. Sempron 145, 4gigs RAM, ~$100 Mobo, Gold or platinum PSU to power 3 or more GPU's.

For mining rigs with more than one card you really need an open air setup IME. I've had best response in temps from using PVC to build an open air miner. Get temps down, volts down, power use down and then run 24/7 and don't worry about it until needed.


If you want to continue the route of the 280x plus another card for which the other card will do productivity during day and mining during the night then I think the 270 is the right choice. You can undervolt the 270 to the 1025 1075 range and get ~400-430Kh/s (980/1500 core/mem, intensity 18, TC 16384). This gets power draw down to ~120watts. Asus or MSI versions.

so I've got 4 cards. Do you guys make 4 workers? It's actually easier this way for me to see which card might need tweaking.

I'm thinking if I use all 4 cards on 1 working account I would get less stale/invalid shares, does that make sense or am I off my rocker.

 

[blastingcap]

Use four workers, easier to track if one bites the dust or something. You will not gain any advantage in stales/invalid.

 

[holden j caufield]

ok thanks. yes it's much easier to see which card stopped mining this way.

 

[nwo]

When I get issues on one of my rigs (I run a seperate bat file for each card) the whole thing usually goes bust.... Either cgminer just stops mining and freezes up on the current hashrate with no error message or my PC locks up/reboots because one of my cards crapped out... So I use 1 worker per PC.

Stock as in whatever is in it's bios. So you can tweak it if you modify the bios.

How do I modify VBIOS?

I've never seen such an issue, but in your case I see why you would do it that way.

 

[Kosmic1]

Thanks Attic. I'm not quite ready to build a full-on dedicated 3-card miner, and I can't get any more vapor-x 280x cards at the moment anyway. I will probably go with the 270 as you described, and then see where I go later.

profit is identical between having 4 cards share 1 worker and having a worker for each
the only reason to make multiple workers is to identify problems. Such as noticing that card 3 is under performing or even to get automatic notifications when a card goes offline. Typically you can set it to auto notify you if a worker stops working so you can get an sms saying "worker 3 is offline" and know what to fix

A Swiss company is making an ATM that can do EUR to BTC/LTC/DOGE...

May be the start of crypto "banking"

DOGE!? Really!?

You're kidding about the doge part though, right?

Didn't the EU legitimize cryptocurrencies some time ago and officially allowed banks to deal in them?
