Riding the Crypto wave

[aGeoM]

Hi

Received today on my bank account my first payment (Jun 20) from Coinbase, only 2 working days from payment, bank account verification and transfer, and the amount of money I had to transfer to verify my account was refunded to my Euro wallet. Really great.

BTW Running 2 systems, the one with power meter is pulling 190-200W and it is an 6300FX, MSI 970 Gaming with HD7870 including Monitor. My main rig I don't know (MSI Tomahawk + Ryzen 1700 + RX480/580) total power but GPU pulling 93W (GPU-Z reading).

I don't know if running a 7870 would be worth it. You're looking at 1.52 USD/day after power costs running that (rough guess based on the profitability calculator).

If you're serious about mining, you may want to try grabbing a pair of GTX1060s or 1070s for that rig. They'll do better for you.

I have one running for free at the shop and even before electricity it is still pretty low.

There is no such thing as a 100% efficient power supply. Even 80+ Titanium units (Titanium being the most efficient that currently exists) suffer from efficiency loss. If your rig requires 1000w, you WILL pull >1000w from the wall. How much more is up to the efficiency of the power supply you have. You have a Platinum unit which is already very good, so there's not much you can do at this point. My best advice is look for a Titanium unit if ever you need another power supply, but don't worry about changing your current unit. It's already really high end and upgrading to a Titanium unit won't be worth the cost. You'll get somewhere around 2% more efficiency, that's all. Even if your rig requires 1000w, you're looking at <50w savings on the power draw here.

Fair enough.

Btw, i will do some tests later with another power supply, i will power the 1080 with and external power supply to see how much electricity it uses.

I doubt it uses that much, but the FTW 980Ti I have does use more power than the reference board at the same clocks. Just FYI

Let's forget about how well they do or not, my main concern is why the power meter is showing 331W if the card uses 180W let's add 20W more 200W so 200 to 331W there's a difference of 131W, what could be using 131W in the system? as i have said before the System it's running at stock and save mode power plan and the other cards are running with an external power supply

id investigate the power save os feature, some bios config switches can render it mute, so it could be a power save feature, or cpu feature turned off or even an alternate software switch for example ,amds overdrive software will do that for me if the top right button is switched to red?? i know not the best discription but thats what it is with no id or nothing on the button and the helps got nowt but its boost ,anyway.

Hey you never know it could just be what the card is consuming

So this is what being handed two free EVGA 980Ti classy's looks like

In that case i would sell the 1080 and buy 2 x 1060/1070

I started mining after reading this thread, and I have a bunch of hardware laying around just for benching (no much time ATM), so I set an 2nd rig to test old graphics cards (AMD's 3870,4870,6950/70 and 7870), only the last two worked with NiceHash, 6950/70 mined Pascal at 0.70€/Day pulling almost 300W from wall not worth it, the 7870 with a heavily modded BIOS ( 7970 PowerPlay and Voltage Object Info, Hynix AFR Tahiti timings on a Vram Info from an X270) is mining EquiHash at 975 GPU/1600 MEM @1.45v for about 200.000-220.000 Sol/s, meaning +3€/Day, Power bill is 0.14€ KW/H pulling all system 200W total, isn't the best but it helped the payment of 53€ at the end of the week.

At this early stage of experiencing I don't know yet if I go or not for serious mining, I have to invest a lots of money that I don't have and mining until I got some will take a wile, I need cards and cooling systems, ambient temps here are about 33º ATM, keeping cards running 50º-60º 24/7 are impossible without proper cooling. Never the less if I can grab one of the new mining cards, it will help on the quest.

Well, far as I know 1060s don't run super hot, and they should do far better than a 7870 (each).

My cards are backordered and probably won't even ship until July 3 they're giving me a $50 coupon though

 

[yotano211]

I would love to get a hand on about 119 of those Nvidia mining cards.

 

[hat]

I'd just be happy to get my hands on the two I've ordered, and then two more in the future once I've earned some profits...

from where did you order those mining cards from

Yes, they should but I already have it and buying an 1060 will cost me minimum 225€, if I spend money on mining have to be with mining money, until then I will wait and see how the things go.

I just found 6 480/570/580's at old retail costs

Dell. It's the only place I can possibly shop right now, as I have credit with them. The cards I picked are already backordered though.

oh wow what a find, resell them and get 1070s. You can sell them for almost 1070 prices, if not add some 30-$50 and get those 1070s.

You missed my above post? I said I got them from Dell. Unfortunately they're backordered and they won't even ship out til the 3rd.

 

[enzolt]

So when do you actually make a decent profit? Taking into account startup costs with the hardware and electricity cost. 6 months?

 

[hat]

Personally, best case scenario I clear my original investment in 75 days upon receipt of my graphics cards, at 12 bucks a day. After that it's basically free money. Doesn't seem like much but that's around 300 bucks a month. If I could get two more 1070s that's 20-24 bucks a day, but I need more hardware to make that happen.

Of course the greatest chance lies in the bitcoins themselves. Once I clear my investment and some other debts, I could just pile up bitcoins and they may become really valuable in the future.

If I can get them tomorrow I will. The question is will they last long enough for me to grab them (benefit of snagging the in transit reports lol)

Finally i have found where the problem was.

First thing, my Machine uses 65W in idle, the card has been always using 180W.

So, last night I tested the Machine just with the 1080 SC installed and the power consumption was 245W/247W, 180W that the card uses + 65W for the System, after that i added the 2 x 1060s, and the idle was 75W, so launched Nicehash and the power consumption was 255W, 180W for the 1080 and 75W for the System with the 2 x 1060s that added +10W, launched Nicehash with all 3 cards running, and here comes the funny thing: the 2 x 1060s were powered with an external power supply but because are installed in my machine they added 100W when mining and it doesn't matter if they are powered with an external power supply, so the power consumption was 355W, 180W for the 1080, 75W for the System and +100W that the 2 x 1060s added because they are installed in the Machine and running in full load.

Note: I have always thought that powering the cards with and external power supply it wouldn't add any Watts to the System, unfortunately i was completely wrong.

Yeah they still pull 75watts per card from the pciex if direct inserted thats why people use the extenders, to stop the mobo frying with more than four cards ,it likely would too.

In my case they are just pulling 55W per card.

Right now i am just running 2 cards in my system, the Classified and the Superclocked, adding the 1060s it's impossible because it's too hot and a few times they shut down, still waiting for the hardware i have ordered.

After i have the Mining Machine running with the proper hardware the power consumption should drop off approximately 50w or more.

Idk if anyone else has noticed but my profit per day has decreased by just over 1usd since i started mining less than a week ago. That's nearly a 20% decrease already. Profitability will continue to become more and more difficult as more people mine. I wouldn't invest too much in this endeavor. Don't get burned
