Should I quit or keep on fighting?
-
Hey guys.
This last week after I got my first parts for building a miner has been a tough one.
I’ll give you the short version. I have spent around 3875$ on parts for building and for upgrading the PC I use daily, to mine when I’m not using it.
Currently, the power consumption is around 1500w and I get 3330KH/s.
The electricity in Denmark costs around 0.36$/kWh (lots of taxes).Right now that would bring me to ROI in about 155 days. But this stuff is NOISY and I’m living in a shared apartment and getting really unpopular from this!
I’m going to have to either just quit after this one week, having lost a lot of money… or keep on fighting and invest another approx. 1500$ to get water cooling if I want to continue.
This would mean 5,375$ invested and 216 days to ROI.
So I just need some opinions as to whether I should cut my losses and quit, or keep on going. I know nobody can foresee the future, but I just want to hear what you all think :)
Thanks, guys! :)
EDIT: I would be able to cram another card into the rig eventually and get up to at least 4mH/s all in all at around 1700-1800w, so I would end up with ROI at 179 days with the current rates.

I do not still manufacture my devices mining…
but …I think it is best to cool with vegetable oil, and cooling the water in heat exchanger …

[b]My idea is to use a water pipe inside the tank with oil, and this cool with any automobile radiator and electric fan 12V respective[/b]
[b]Very quiet and very cheap![/b]

I would choose liquid cooling option tbh, but even with that you still be noisy, as pumps and radiator fans still makes noise.
Another option : Try to explain your room m8’s about idea possibility and bla bla bla. And convince them to share your investment :) Just offer like 5%-10%-20% “shares” of your rig - all winz :) -
no one likes a quitter! tell your roommates to buy earplugs! :D
the thing to bear in mind is that the difficulty is so variable, so just because at todays rates you can break even in x days does not mean that you will…also, so much of the break even is based on price, and FTC have dropped a fair bit in the past couple of days which will extend any break even time.
surely at this time of year, you could take the side of the rig and put it near an open window! that will cut down on the temps and the required fan speeds…

;D idea…
modifying Split Air Conditioner and Pump… ;D

Here’s an option you might consider. I play guitar/bass/drums/etc. In my basement I have a room dedicated to this. For very cheap, you could probably do what I’ve done to not disrupt everyone else and sound proof your room. Just google “home recording soundproofing” or something similar and get plenty of good advice.
@Ernesto
I love the mineral oil computer tanks! (To be clear, don’t use veggie oil). I build one a couple of years back just as a showpiece to have in the living room. They are a royal pain in the butt if anything goes wrong and/or you have to swap out any hardware. Huge mess. Also, I definitely wouldn’t use that type of a setup for a mining rig. It’s too much of a hassle to deal with swapping out parts and I don’t trust the cooling capabilities compared to what I’m using currently, which is just stock fans and an open case design. Also, the viscosity of the oil becomes a probably with the moving parts (fans) and causes them to wear prematurely. They do look awesome though! Especially with blue leds and a little scuba diver guy in the tank :)Regardless of what route you end up taking, I don’t think you should quit if this is something you want to seriously pursue. If you continue to be courteous of your roommates and keep an open line of communication, I’m sure you can work something out.

Thanks for the suggestions, guys! :)
The window is already open, but it’s not enough.
I’m not too keen on the oil cooling because of the problems it can give when you need to remove it.
I like the idea about a “rehearsal room”.
I actually put up a bunch of boxes, pillows and a sleeping bag to catch some of the sound, and it helped a bit.I will probably order some heavy, acoustic curtains and see how much they can do :)

[/quote]Wouldn’t it be cheaper to reduce intensity by one and see how the fans behave?
Also I keep my fans relatively silent by allowing a target temp of 78°C, overheat 80°C and cutoff 82°C
I noticed on my card, that the fans are relatively silent, when running below 50% of max speed

[/quote]When I drop them by one, the lose a lot of speed. But actually, it’s not a bad idea. During night, I will drop the intensity to keep my flatmates happy until I find a better solution :)
Thanks! :)

Hi I don’t know a great deal about mining, but you really shouldn’t quit this, you came to mine some crypto and you aren’t just limited to feathercoin, get what you can while the getting is still good. These break even estimates don’t take into account future values of the currency…

In the test is that the vegetable oil is better than mineral oil coolant and air.
As vegetable oil is not derived from petroleum, does not attack the embedding in plastic components and oil components. Then it can be removed more easily the vegetable oil.
The components are not going to ever wear, it is impossible to wear submerged in oil.:)

Also keep in mind, you could always sacrifice some kh/s for undervolting + downclocking + lower noise + lower power consumption.
example: R9 280x’s may run @ ~1.07v 1000mhz/1250mhz with -g 2 -I 13 hashing @ about 680-690kh/s
fanspeed @ 50% temps @ 65-70°C (ambient 20°C);)

^ that is a sound plan

look into that thread, If i remember doing my calculations correctly you should be able to ROI faster optimizing for power due to your crazy $/KWh…
I run 2 settings, the first is an optimized all out setting getting me 740KH/s per 7970 and the second is my quiet power optimized setting 660KH/s that drops temps about 12c. -

That sounds good :)
But doesn’t vegetable oil get bad faster? Well, I will read about it a bit more and consider again :)[quote author=nimmneun link=topic=5844.msg43109#msg43109 date=1386784585]

I’ve been trying to undervolt. It seems that the core voltage is locked on these XFX R7970 cards, so it’s not so easy. The idea is good, but I just haven’t found a way yet.

[/quote]I have been reading and learning from your thread. Very impressive results!
But as mentioned above, undervolting didn’t go so easily for me. In Afterburner, the voltage is locked, so I did a combination of Afterburner and Trixx. After that, the speeds started dropping over time. It’s back to normal now, except it’s hashing somewhat slower than before. Around 667Kh/s per GPU. Anyway, I think I know the process of getting it back up, so I just need the time to do it.
Any clues on how to unlock the voltage clock on those XFX R7970 would be appreciated :)

Well, i stay go ahead and continue. Try explaining the situation to your roommates, and offer them some shares in your already built rig, theyll be interested then and will start to actually take interest in the mining rig instead of blaming you for the noise :p.

I see your point, which S2 Bergen also made earlier in this thread. I’ll see if I can spread the love for mining ;) -

[/quote]yes undervolting will drop temps alot

my rigs actually are serving as my heater in my apartment lol
