guys who where telling me that 2 memory sticks will be cap, and there wont be any speed increase if i add more memory where wrong. Ading 2 more sticks to my current system increased my performance by 10% without any over-clocks. Video : https://www.youtube.com/watch?v=xeVhjAfgMqw&t

I think it is so high cause most of the miners have CPU which are sitting idle, so it makes sence even to put on a celeron which does no harm to earn extra few cents. Still ROI is better then mining any other coin with GPU.

Waste of time, buying coin seems much smarter choice currently if it is for profits

So Monero Hardfork has executed set at block number 1978433 .Which has been successful as they usually are. Now there is new mining algorithm for Monero , and this change has made previous mining hardware obsolete. What I mean by that, there is more profitable hardware which are CPUs to mine monero. Previously most efficient was GPUs.
In my case most efficient hardware is Ryzen 9 CPUs, which gets me best watt per hash. Some people this might be different. As the electric and hardware prices changes different places on the planet Earth.
I just wanted to follow up on mining probability, what is going on and what are the current changes.  So after about 48 hours in new algorithm RandomX, Total network has stabilized at around 2.5x which is 750mh , network hashrate before RandomX was around 300mh/s

This was expected, for example if we had monero mining rig 6xGPU RX570 which on average was giving 5000 hashes price (1300euro)
Current hardware Ryzen 9 mining rig (800-900euro) gives you on average 13000 h/s which about 2.5x cheaper hashrate then on previous mining algorithm . Pluss the watt per hash is much more less then the GPU rigs.
Total network hasrate could increase even more, but I don’t expect it to increase that much anymore. As the profit is just not there, and the roi isn’t that fast.
Currently calculators show 0.9 XMR a month with one Ryzen 9 CPU.
Im just curios now what is going to happen with previous  Monero Network mining hardware is it going to hit other Networks or be sold in open market. I will probably do a more close follow up on few weeks and will see where it stands.

If you build rig with only RX5700 you will get about 650 mh/s at 1900w
So you will need :

• 12xRX5700 each about 300-330euro
• and i used all in one case 680e - https://mineshop.eu/mining-container-minebox/minebox12-all-in-one-12gpu-mining-rig-case/

What cooling you using, is it the stock air cooler?
How much you pulling power from the wall?

Yes FPGAs are very tricky. Specially if you cannot develop your own bittstream. There is very little software and if there is the dev fee is crazy, i remember last week buying 100usd worth bittstream  for CKB nervous which at the time was doing about 20usd a day, and still it has another 10% dev fee in it. Which is crazy high if you compare it to current gpu mining software  dev fees average 2%.

GPU seems to me always the best choice for mining. Yes the profit currently is just not there, but that could change very quickly. If it does you can build big farm in few days from GPU cause the hardware is easy accessible.

Im sorry
You can go here i have also post where you can click on images https://mineshop.eu/2019/11/27/ethereum-mining-rig-rx5700xt-vs-rx5700/

What are the voltages?
Not sure about your timimngs

Seems like a option, i wont be running it over 80c in any case. I rather then reduce the clock peed and voltages.

RX5700 series graphic cards has been out for few month now. But drivers for mining from AMD hasn’t been the best. Recently most popular mining OS Simple-mining and hiveOS has added support for these graphic cards. It is not perfect but mining is doable on these cards now, and the results are impressive. Im not saying here GPU mining is now profitable, you still have to be mining fanatic like i am to build GPU mining rig with new hardware.

My setup for 324mh/s mining rig:

12gpu all in one mining rig case
5x RX5700
1xRX5700XT
hiveOS mining software


Over clocks used :

Core Clock 1340
Core Voltage 800
Memory clock 930-950


My setup for 500 mh/s mining rig :

12gpu all in one mining rig case
5x RX5700
1xRX5700XT
6xRX570  4gb MSI gaming
hiveOS mining software  https://hiveos.farm/install/
Over clocks used :

Core Clock 1340 (RX5700) 1100(RX570)
Core Voltage 800
Memory clock 930-950(RX5700) 2030(RX570)


There is nearly no difference in hash-rate RX5700 and RX5700XT . It is no point spending extra 20% on gpu to increase hashrate by less then 1%. So if you are mining Ethereum stick to RX5700

It will be used for mining also.
My plan of this setup is.
MSI B450 Tomahawk max motherboard
2x3600mhz ram
2xRX5700
Ryzen 9 3900x

So not to waste other hardware i can do dual mining for example with GPU i mine ETH.
Also can use it as gaming and rendering bench.

Thank you for feedback
3rd generation Treadripper should be out soon, havent really followed they release date. Price range seems attractive.
It would be great if we would get some dual CPU boards for them.
At the end of it it will come to price per hash 🤞

I think you need to find that balance to not overpay by every hash. In some cases it might be better just to reduce the OC and get reduced 10% hashrate and power then purchasing expensive cooler. Everything comes down to OPEX and CAPEX.

Temperatures was quite hot 83C after working for about 30 minutes. But my room temperature quite low about 15c.
This was just overall test, ill have more efficient ram by end of the week.
Need to find that sweet spot where you reduce core voltage and not loose to much hashrate. To not get the CPU to hot with stock aircooler.

GPU was idle yes.

Test bench setup :

Ryzen 9 3900x with stock air cooler

2x Gskill 3000 16gb C15 RAM modules

MSI B450 Tomahawk MAX motherboard

1xRX5700 for image

Superflower 750w GOLD powersupply

As there are few of the coins switched to RandomX mining algorithm already and one of them is Loki. So on stock settings everything out of the box we where hashing Loki at 11500 h/s. Which is about 5x then in our previous best tests with Intel i7 8700k out of the box 2360 h/s. Power usage from wall is 260w.

So we tried to push little more speed on the Ryzen 9 CPU , by overclocking it in motherboard BIOS. Changes done :

OC Explore mode to expert

CPU OC ratio to 4100 mhz

A-XMP to enabled

Precision Boost Overdrive to disabled

Play with DRAM timings (lower the values)

CPU core voltage to 1.250v

Increased Dram voltage 1.300v

This setting got me up to 12650 h/s mining RandomX. I was playing around with different kind of ram stick , and seen significant mining performance decrease with lower performance ram. So i have on the way 4x3600mhz 8gb stick and will do a proper performance test when they arrive.

So the 12650 h/s if you would be available mine monero today would be 3.5 usd , even that it got 10% price drop today. But you know it is not the case, impossible to predict what kind of total network hashrate will be when Randomx launches. As the total network mining structure will change and the current hardware will be unprofitable. Current Monero network hashrate is around 300 mh/s.

Profitability with Ryzen 9 mining Loki which is also RandomX mining algorithm. Daily profitability is 0.70usd

Im eager to see what RandomX mining will bring to Monero mining. What is your thoughts?

Nice performance compare to 1070TI, and probably much better power usage

thank you
