New mining rig suggestions

[dawnn]

So I have been thinking about investing in a mining rig, mostly for fun.

Would I be better off getting a GPU Mining rig with say 5 or 6 ATI 580's or some other GPU

Or should I go the ASIC rout and find a couple Ant Miners.

WhatToMine says I can pull 15ish bucks a day depending on the Alt Coin that I mine, but it looks like pools are really power dependent.

Any seasoned information for a Noob would be appreciated

Thank you!

My take is:
1. Research what coin you believe in. Something you think might take off some day.
or
2. Just mine whatever is most profitable with existing hardware.
3. Base your decisions off these choices.

So if you are set on a coin, you already know what cards mine it best. I say if it's for fun, just do it. Especially if you can find cards at a decent price right now. I don't mine anything with ASICs, only cryptonight based coins so I can't comment on that. And be prepared like any PC hardware related hobby to never feel satisfied and always have the itchy trigger finger to pull the trigger on upgrades.

dawnn here is a relatively on-point article for your use case.

Note this little blurb about the performance differences between 3GB vs. 6GB 1060s on Eth:

Using Claymore’s Dual Ethereum AMD+NVIDIA GPU Miner v10.2 we are able to get around 24.3 MH/s from each GeForce GTX 1060 6GB video card and 20.3 MH/s from the GeForce GTX 1060 3GB

And about your profitability at current factors w/ this setup:

If you are able to pick up four NVIDIA GeForce GTX 1060 6GB video cards at $240 each you’ll be getting about $295 in ETH per month before electricity costs. At around $0.10 per kWh you are looking at $28 a month in electric to run this rig 24/7. At the current ETH price, DAG Epoch size, difficulty level, mining pool size, mining reward and transactions a day you are looking to bring in around $261 of profit per month on .435 Ether or $3,100 a year after electric costs with a rig like this.

amd sky 900's but im the only one who has those so idk about geting any dont touch asics.

For my $240, I'd rather get a pair of 1050ti 4GB, and pull in 30Mh.
Were talking Microcenter open box or EVGA B-Stock prices here.

Extra consideration must be given to slot power and not load more
than 1 riser per string of peripheral cable. You may never be able
to overclock these cards on a riser without burning something.

Set core slider to minimum, and don't even think about moving it.
OTOH, you can bump memory up +400, maybe +600 Samsung.
If not occasionally setting a fire, may not be trying hard enough.

That said: Compare the propsed four 1060 6GB to my rig of eight
1050ti's which draw 518W from the wall, give 120Mh, about $350
per month profit. Measured power includes two i3 threads of ETN
mining on the CPU for another +$18 per month.

What 1050ti 4GB are you using? The smaller pcb type?

 

[dawnn]

Thank you for the input guys =) I am going to be looking at Hardware today and see if I can get some cards.

If you end up going the 1050ti 4GB route, might be worthwhile to get this specific version of SIPOLAR riser.

Cost is reasonable, even cheap, but paid shipping time for me seemed a little slow.

Can't swear it will solve all slot powered GPU problems, but I ran one on the bench yesterday for a while
with 3.3V 3A electronic load, and conversion efficiency was around 80%. No component even got warm.
Compared to ordinary risers, pair of discrete MOSFETs really do seem to help. I didn't have time to burn
in at 5A, or challenge the resettable fuse to see if it really resets.

Don't use the included SATA adaptor which will bottleneck your 12V input to one wire.
Use real 6pin supply cable all the way, else wasting your time...

So what's the minimum and preferred cpu for a mining rig running a couple gpu's?

Celeron G3930?
Pentium G4560?

xeon l5520 there really isnt a minimum though.

Lots of people use both. The celeron is fine for a 6 or 8 card rig. That g4560 has hyperthreading.

 

[atp1916]

Had no problems using the G3930 with 8 card RX580, 1070, 1070 Ti rigs.

Just don't be doin no Sempron single core rigs like i saw folks doing back in 2013/2014 :/

Any Ryzen on B350 board will quickly pay for itself.
Eight threads of ETN or XMR brings in an extra $80/mo (Ryzen7).
Probably half that for four threads on Ryzen3, I havn't benched...

 

[QuintLeo]

Ryzen are a lot longer payoff mining Monero than the old FX 8xxx series are - they DO mine faster but cost quite a bit more for the higher-hashrate options.
Limit is "2 MB of core per thread" for efficient mining - my Ryzen 1700 with mild overclock pulls about 400 hash/s but my "converted Folding rigs" with FX 8320E pull 300ish with about the same power draw for the CPU and COST over $200 less.

Sempron single-core IS still viable for rigs on some coin, but IMO you'd be better of with a low-end dual-core rig.
My "big rig" triple R9-290 runs a Sempron 145 without issues (the CASE is what makes it my "big rig", it's not even close to my highest performance rig any more).
My B250 Mining Expert (overkill for right now) with 6 cards (mostly 1080ti) runs ZEC mining with EBWF with fairly low load on the G4400 CPU.
