CPU mining

[Marsh]

What Marcoi said is true to calculate today's ROI.

Last year in, I started mining XMR, I was too caution and too slow to ramp up number of machines.
I was making may be $1 to $10 a day, or mining 0.7- 0.9 XMR per day with 8 x E5-v3 miners.

You see where I am going,
Today, XMR is over $150 , 8 x E5-v3 miners would net me less than 0.1 XMR per day.

Unless you have a crystal ball, Cryto mining is like buying lottery ticket.

 

[Marsh]

Just a interesting fact.
When I started mining, I was solo mining XMR with 4 x E5 v3,
then found a block within 3 hours, it worth 8.9 XMR.

I serious doubt that with current Monero network hashrate , that I would ever find a block with 4 x E5 v3 nodes solo mining.

Any quick and easy guides to get a bare metal server mining aeon coins? I have an intel with 2 e5-26xx v2 cpus offline and i want to tinker with mining and dockers stuff.

Compile miner using following instructions for platform. Ubuntu instructions also work for Windows subsystem for linux if on Windows.
Home · xmrig/xmrig Wiki · GitHub

Run command, substitute pool address, port, and wallet-address in string below. Command below is for AEON

./xmrig -a cryptonight-light -o stratum+tcp://url-of-pool:port -u wallet-address -p x

@cperalt1 thanks for that. I'll give it a go when i get a chance.

If you want to mine using Docker on metal... we have a custom image that has the pool address/ port defaulted

Im installing ubuntu 17.10 then dockers ce to run the image, is that correct?

What exchanges are you guys using to cash out XMR?

@cperalt1 thanks for that. I'll give it a go when i get a chance.

I get the following with running the app bare metal

I have done exchange XMR to BTC or ETH then cash out via coinbase.

Better way is to buy stuff from @Patrick's fs thread, then sell it on Craigslist or ebay. I made out well doing that especially if was gear I needed.

I think your CPU could do better.

Marsh, how to enable huge pages looked some commands but need assistance, using ubuntu 16.04 LTS
Thank YOU

 

[MiniKnight]

sudo sysctl vm.nr_hugepages=128

That should be it.

 

[Marsh]

add this line in /etc/sysctl.conf
vm.nr_hugepages = 60 or 128

if you haven't done this yet
add these lines in /etc/security/limits.conf

* soft memlock 626688
* hard memlock 626688

reboot system

 

[marcoi]

Thanks for tips guys.

Right now I trying this out on virtualbox VM on my laptop. I assigned it 6 out of 8 cores and 2gb ram.

 * VERSIONS:     XMRig/2.4.3 libuv/1.9.1 gcc/7.2.0
 * HUGE PAGES:   available, enabled
 * CPU:          Intel(R) Core(TM) i7-6820HK CPU @ 2.70GHz (1) x64 AES-NI
 * CPU L2/L3:    1.5 MB/8.0 MB
 * THREADS:      4, cryptonight-lite, av=2, donate=1%

seems to be doing well enought?
speed 2.5s/60s/15m 320.6 294.4 n/a H/s max: 412.1 H/s

seems to have maxed out at 520.5 H/s. It using 4 threads, which is about 60% of my cpu capacity. If I increase it past 4 in the vm, the whole system starts to suffer. right now it running without major drawbacks to rest of the OS. I might run it in the background while i work my 9 hour days

Side note, not sure exact power usage, but with my laptop, alienware graphic adapter with 1080 card (idling) and 3 monitors, a few switches, etc. im only using 260-270 watts. i may get a my kill-watt out and check just the laptop at some point.

Note 2: looks like the averaging about 300ish from the last few have reports

 

[Marsh]

Try this out
force xmrig with av=1 thread=8.
I did the same with a E3-1240v2 , it gain 50H/s

Looking at your result further.
My E3-1240v2 is equivalent to I7-3770 , it is getting
[2017-12-02 23:03:22] speed 2.5s/60s/15m 1053.2 1053.0 1052.9 H/s max: 1081.0 H/s

I stared xmrig with
mining threads 8
algorithm variation 1

Reduce number threads to accommodate your workload after trying threads=8

 

[marcoi]

so now the hash report on xmrig is 697.5 yet on the mining pool it saying Hash Rate: 1.78 KH/sec

im trying to compile the nvidia code but i thing its time to go to bed. (2 am here)

The 8/1 combo didnt seem to have made a difference. it slowed down my desktop quite a bit.
I think the sweet spot is 4 threads. and for the i7-6820hk cpu av=2 seemed faster.
I also set the vm CPU to 4, seems to have helped.

I did compile the nvidia and running it with 14 threads on 1080 card, produces around 1200 H/s.
