Main problem with Cryptocoin mining currently is...........

[Klee]

Lack of AMD RX 580's and Rx 570's.

For the past few weeks I have been needing to get 6 matching GPU's , either 580's or 570's, but they are out of stock and the ones that are available are way WAY over priced.

I bought a Biostar mining mother board a couple of months ago and still do not have any gpu's for it.

I saw a RX570 MSI 4 gig card listed for sale for almost $400.00, that ain't worth it at all.

I even been thinking of going with RX560's but the price to performance ratio is worse than either the 580's or especially the 570's.

 

[Patrick]

No on the RX560's. I stopped buying 1080 and below on the NVIDIA side because I realized that each PCIe slot costs quite a bit. Of course, these are not pure mining rigs since they are deep learning first, mining second machines so I wanted bandwidth instead of X1's.

I really like the @Spotswood Rosewill mining setup. Perhaps, if he sees a notification, he would post it in this new forum on STH.

If you already have an AMD setup then I would say you should definitely diversify into an Nvidia one as well.
The 1070, 1080 and the beastly 1080 ti are really strong at mining different coins than the AMD gear.

I'm going all out on 1080 ti's, and then building a vega rig once they drop

 

[Biren78]

I'm waiting for Vega. Easier to have less GPUs to manage.

I got tired of not finding Gpu's so I'm going all in on CPU mining, one open compute server will have 4 E5-2660 V1's to start and the other server will probably have a mixture of two different pairs of E5's.

Parts are ordered to build one asap, really only cpu's and ram as I already have plenty of used hard drives I can use , and just need to decide on cpu's on the other.

By my calculations they will have comparable performance to a open rig with 6 gpu's and be alot more stable at about ~60-70 percent of the cost and a whole lot less tinkering involved.

Open rig with 6 Gpu's at about ~3700 h/s

Two open compute servers at about ~3400 h/s depending on the cpu's

Also I think the power will be comparable.

Will start a thread as soon as the parts start showing up.

@Klee

When you put the rig together , please record single E5 v1 , v2 vs dual E5 v1 or v2 cpu power usage.

I used a SuperMicro dual LGA2011 board , installed a E5-2660 v1 cpu, running Ubuntu 16 with xmr-stak-cpu miner.
1x4gb ram per cpu , 1 SSD for OS.
1 x E5-2660 v1 (BIOS disabled 2 cores , active core=6 )produced 42x h/s , consumed 80w , good number for power usage.
Then I installed
2 x E5-2660 v1 (BIOS disabled 2 cores , active core=6 per cpu )produced 84x h/s , consumed 182w.

I also tried E5-2650v1 single vs dual , E5-2670v1 single vs dual
Could not understood why there is no power saving? Instead it consumed 20w more power.

I actually like CPU mining more than GPU mining due to lower power consumption and lower startup cost.
In North CA, we pay $0.28 KW/h, every KW/h save is good.

@Marsh with the rates, and increases and Solar becoming a reality to pay back in 5YR or less relatively soon with the bills going up... could get more than enough solar and mine with the power and get solar pay-back in <5yr... something you've looked into?

 

[Boddy]

• Solar will be even more sweet when battery prices come down. I seen a 5KWh solar with a 7Kwh battery in Australia for $10K (solarlink).
• Some power companies (AGL) are looking to subsidise solar+battery set up (in South Australia) (if they can use the battery power in the event of back up).
• What could be cool is using off peak electricity (half price in AUS) to top up battery ( I have not done the sums) but my friend who installs solar has gone this route.
• Some operators are looking to pool people's battery storage (using software) to resell on the electricity market when demand/prices are high, to return better profit.

 

[Klee]

Depending on where you live and your electricity provider some have to buy your excess that you produce so you can have a setup where you do not use batteries. If you use more than you generate then you pay then if you produce more than you use then they credit your bill.

 

[Boddy]

Here in Australia peak charges are $0.35 Kwh and they pay $0.06 Kwh for your excess. It's a rip off!

 

[mjygvfesz]

Makes me glad I got .06 kwh power.

 

[whitey]

.11 kwh here in Denver, I guess I should stop b|tch|ng

 

[T_Minus]

.24 base rate here in CA @)*(%@*)@

 

[Klee]

Someone posted on a web forum yesterday in the am that the asus rx570's were available at newegg within two minutes they showed sold out.

 

[capn_pineapple]

I'm in the same boat as Boddy... I have 0.30 /kwh though I do get a nifty pay on time discount. Still, the crypto payback don't justify the startup costs for me (got other stuff to get with the capital $$ it would cost)

 

[Klee]

Just looked on ebay for used RX 480's, it's crazy some of the bids are WAY over $300.00

Now i'm thinking of putting mine on ebay.

 

[Patrick]

I think @Marsh got the deal of the century!

 

[Klee]

I'm thinking that I can sell my two RX480's and dig out an older video card to tide me over for a few weeks.

If I can get more than what I paid for them a year ago and after they more than earned their cost back mining.

Maybe a 1080 Ti is in my future.

 

[Marsh]

I am in the middle setting up a mining cave in a spare bedroom.

Lots of HomeDepot wire shelf rack ( reason for the selves openness , light weight as well ).

Noisy E5-2660 v1 4nodes will be in the garage area, 800w per chassis , great space heater in winter , just not during summer month. I have 5 such beasts , total 20 nodes of E5-2660 and E5-2670, It is just too expense to power them at $0.28 per KW/h . So I'll keep them power off until XMR price is extremely high.

Next up is to build up a 3-4 GPU card miner, but no GPU cards ,

Going for 1.4 XMR per day within next 2 months

 

[Klee]

I janked out the GTX650 card from my recently rebuilt built Nas4Free box, powered on and it works fine without a video card.

So tomorrow night I'll pull out the two RX480's and clean them up and put them on ebay.

So i'll also do a fresh install on Windows 10 and go from Ubuntu 16.04.02 to 17.04.

I figure if I can get the prices that I'm hoping that I'll get for the pair of RX 480's it will go a long way towards a GTX 1080 Ti.
