Title: Thinking about building a 20+ gpu zcash rig with gtx 1050s
Post by: Newminer27 on January 26, 2018, 12:28:52 PM
Ive been looking around and havent seen anyone say anything about this idea. The gtx 1050 is one of the only cards that is reasonably priced, they can be had for around $120 on amazon, in stock. Now according to this site https://en.m.wikibooks.org/wiki/ZCash_mining_GPU_Comparison

The 1050 should yield about 150 h/s on zcash. With 20 cards in one rig, that would be 3000 h/s for about $3000.ive heard of a motherboard that can support up to 19 gpus so this would be perfect for that. I used an online calculator that stated that i would be making about 500/ month from this rig afterf factoring power consumption.  Seems like a way better deal than spending that same 3k to get 3 1080s and only get half the hash rate (gtx 1080 aroind 550 each so 1650h/s for a 3 1080 rig. Theres probably something im missing making it not the best idea but it seems great to me

I think if have read the effiency is not so good on 1050? If not, or power is cheap. Thats a good solution, special of the "new" prices for gpu's

Well, just an FYI the ASUS B250 Mining Expert board, which supports 19 GPUs. DOES NOT SUPPORT 19 OF THE SAME GPUs. Currently the only support configuration for 19 GPUs, as shown by BitsbeTripping(See his youtube channel) was 6- P106 Nvidia mining cards and 13 AMD GPUs. THIS IS THE ONLY SUPPORT 19 GPU CONFIG.

As for a GTX 1050(non ti) build I think we are seriously reaching bottom of barrel here. I mean you wanna experiment with it, I'd say 6-7 GPU rig AT MOST it could be a low cost/low power space heater that makes you a little coinage.

If you do get something like this, you will definitely want to get a 1050ti.  I bought one for $120 a few months ago, by far the best bang for the buck.  My 1070s only outperform it by about 2.7x

I have a 1050ti mining right now and it struggles to be profitable, I imagine the regular 1050 will be worse.  Seems like 19 1050 would be a lot of hassle for little reward

Wow, seriously, people, what is your cost per kwh?

I ran some numbers this morning on this idea, and for me, $1.28 a day per card (neoscrypt), costing $0.14 in electricty ($0.084 kwh) = profit.

Setup of 12 cards = $2600 and would net $230 a month at a electrical cost of $25 = ROI about 5 months, and could be run on a breaker anywhere in the house.

Was thinking in building my 1st mining rig with 1050ti's could you Share youre rig please? ^^ thanks :)

Yeah that's not a good roi. Underclock and under volt a set of 6  used r9 290x. Mem clock to 1160 and you'll be at aboit 1100w. Mine eth and lbry. Sell your coin and buy zcash if in the end you want zcash. You'll spend about 2100 on the cards. Profit should be about 400 a month, double what you have priced. Take that extra cash and buy a steak every week while you sit back and smile at you acct value

You can ROI if you have cheap elec (.10 cents or less) with certain used cards in under 2 months.....  I picked up many for well under $100 each.

Do not buy 1050's just dont.....

I am not a fan of the topic starter's idea of building such a rig, but buying 3+ years old that have been mining at 300W and 90 degrees C is not any better.
Not to mention that lbry now belongs to asic's territory, you won't make more than 10 cents per card per day - dual mining is not that worth it anymore.

NAAAAAAH, you must not know much about electronics. if they have ran 3 years they are good, probably wont die, just do semi annual maintenance replacing thermal compound and cleaning the card every week to save the fans. BUT thats not even what I was saying.

buy cards that have been used for gaming. there isnt a shortage on ebay and you can tell if they used it for mining when you receive it. Ive sent two back, but then i just started using them even if they were mined on. The fans are the only thing that go bad usually. AND a dead card is worth 100 bucks resale.
I stick to my position.

Oh and 300w is ridiculous when you undervolt and underclock. As for dual mining it works great. recent updates have almost no effect on eth hashrate. I checked my lbc payments and there is a negligible power difference on r9's running dual, and the future of the coin is good, hold, dont dump. yeah it wont compete with asics, but its something on the side.

also what asic is doing lbc? holy crap i knew obelisk has a DCR miner and i have a couple SC miners..but lbc too? or is that the same algo?

I have my second personal rig with 4 x1050 ti plus 2 x1060 3gb. Anyway I want to talk about the 1050 ti and why it can be a good choice together with ASROCK H110+ PRO BTC which supports up to 13 cards.

1050 ti-s are usually 180 USD at ebay but you can find them a bit cheaper on local online marketplaces at almost every country. My personal test with them both cards ASUS EXPEDITION, GIGABYTE G1, ZOTAC keep an awesome level of overclock through MSI at +950 memory, making 14.6mhsh/147mhsh---mining eth/pascal.

6 of these cards can make about 88mhsh/900mhsh together resulting in about 0.00093 btc daily through Nicehash. Electricity is super cheap as these 6 cards only consume about 400 watt and together with other parts they go to 500 watt.

Now double the amount to 12 cards and they consume 800 watt and together with other parts is 900 as one board will keep all of them.

Making 0.00186 btc daily for 900 watt it is a winning bet if you ask me.

So to original OP , your idea is great, the only thing you need to change is the card, from 1050 to 1050 ti as the 1050 ti is a big improvement compared to 1050. You cannot mine ethereum nor dual mine with the 1050.

Forget Zcash and jump in the dual mining arena, there is where these cards shine.

Wow do you got any recent guide for a good mining rig with the 1050 ti's? Everything is a bit outdated :/

I donno, buying a bunch of 1050 ti's doesn't make a lot of sense to me.  Exercise some patience and effort, and you can get enough 1060 6GB/1070/1070 ti and it would be significantly more profitable and more future-proof.

dude theres no 1070 arround here ^^" plus you can get like 4 of 1050ti for the price of a 1070 :/

I would do it personally. The only thing is the extra points of failures with the massive amount of risers. At least the cards don't have any 6 pin connectors. Funny thing is that after posting this idea here on BCT, you better order those 1050s today or they might sell out before you know it.

You should just try and buy some second hand radeon 7950/7970/280x. You can find these for about $125-$150 on Craigslist.

They would hash at 320H/s

Or get some Pitcarins like the R9 270X or R7 370. They would hash at almost 200H/s and can be had for less than $100 most likely.

1050ti are very nice little buggers.
They do take more space i.e. you have to get more rigs and cards but they are very cost effective price of card vs. Hashrate, especially if your electricity is cheap

Example

13,5-14 mhs ethereum 55 watt, 50C
x2 = 27-28 mh ethereum, 110 watt. That's almost like 1070
CoSt of 2x 1050ti  lower than 1x  1070 if you can find it.
Drawback - need more pci szlots and more rigs.

Post by: androstan1234 on January 29, 2018, 10:25:32 PM
I guess it's not a terrible option if you value lower startup cost and getting started sooner.

Two 8-card 1050 Ti rigs will pull about 960W from the wall and hash about 230.

One 8-card 1070 rig will pull about 1040W from the wall and hash about 250.

The 1070 setup is clearly more profitable, about an extra $2/day under current conditions, but the 1050 ti setup will make money too.

Just make sure you take into account the cost of the extra motherboards, extra ram, extra cpus, extra risers, extra frames etc. when you're comparing initial outlay.  That stuff can easily run you $400, i.e. most of the cost of a 1070.  You should also factor in resale value.  The 1070 (and 1060 6 GB and 1070 Ti ofc) will have some resale value down the road.  The 1050 Ti probably won't.

Take all the factors into account.  I'm not saying it's clearly a wrong decision, just that the decision should be based on all available information.

I really dont understand why all the people in this thread keep talking about ethereum. You dont want to mine ethereum with nvidia cards over zcash (which is what the OP said he wanted to mine)

I compared ethhash to equihash via whattomine.com and eth was more profitable for typical 1050 ti numbers.

This is not a good idea.  If difficulty keeps going up you will never ROI.

Probably better to just buy and HODL.  That's been the best way to do things in crypto so far, in hindsight.

I would have 2x the coins if I bought coins instead of mining gear.
