Hashrate seems okay on monero, I'm mining XMR with RagerX and mine hashrate is a bit better as compare to yours.  I think RagerX is one of the best platforms to mine Monero. Why don't you give it a try?

Hi guys, do you have a recommended coin that are good for cpu mining? I have a couples of amd desktop, I just want to add it in my gpu mining aramada, just want to try a cpu base mining coin.

The good and old Monero is the coin you want to mine
Recently XMR changed the algo and it's profitable again for lot of people
You can download the miner and try
How come the monero is profitable again? Is it for real? Is Monero via cpu mining profitable?

CPU algo is only for botnet, not profitable at all

exactly, this is the point, im telling so many years

Monero isnt profitable for mining because the nethash and difficulty rised 3 times.
If you need " cpu rig " , multiple boards with multi cpu support you can have blade servers like c7000 HP or more particular the AMD opteron
16 core cpus . The model is BL465c supports dual 16 core cpus the whole chassis handles 16 of them so 32 cpus in total in 10U rack space.
There are still some qty in ebay and amazon i think but its expensive machine for my pocket.

I think RandomX is a game changer, even more than than MTP. I expect it so have a
longer ASIC-free life.
Asic-free does not meet profitable. CPU-only algo will attract botnet farmers and ali-express ancient CPU buyers. They have low hashes but more than GPU and costs really cheap.
More so the botnets but not the ancient CPU, the cost is too high for the motherboards, atx psu, ram and a flash drive all of them will need.
Im to lazy to count all of it. As i see used XEON costs $10-30, motherboard about $20-30, ram+flash - $20-30, PSU - $25. This is if you buy it. But as for me - i have all of it except CPU enough to make about 4 rigs.

True, ASIC free doesn't guarantee net proftability but eliminating ASICS will decrease difficulty
and improve earnings.
The botnet issue is no different than when Monero used cryptonight.
The GPUs will move to other algos depressing them relative to RandomX.

Nice pun, I guess it could be called an algorism.

The issue with CPU mining is the high cost of build out, the PSU, mobo, ram, CPU and cooler per each build. You could try to buy old servers that have somewhat decent CPU in them and go for that.

not as bad as you think a lot of boards will do the

  ryzen 5 3600x
  ryzen 7 3700x
  ryzen 7 3800x
  ryzen 9 3900x

A lot depends if you were like me when I built gpu rigs I used better boards..


my   x370  all bios up grade to ryzen 3000    mobo cost = 0
my psus were all atx                                    psu cost = 0
I used 2 sticks of 8gb ram                            ram cost = 0

cooler  the  cooler master 240 aio = 70 bucks
cpu    250 to 500

pretty afford able upgrade  if you do the 3800x on sale = 369

https://www.amazon.com/AMD-Ryzen-3800X-16-Thread-Processor/dp/B07SXMZLPJ/ref=sr_1_2?


cooler master = 75
https://www.amazon.com/Cooler-Master-MasterLiquid-Chamber-MLA-D24M-A18PC-R1/dp/B07CRGC899/ref=sr_1_1_sspa?


or ryzen 3700x 309

https://www.amazon.com/AMD-Ryzen-3700X-16-Thread-Processor/dp/B07SXMZLPK/ref=sr_1_3?


so for 369+75 =444  and sell my 1800x for cheap (100)  I get  solid up grade for only 344
If you already have am4 boards, psu, ram then it's not much of an issue but I think we both know what the majority of motherboards used for gpu mining were. They were those crap little 1150 with g1580s in them and ddr3 ram.I doubt many bought am4 to throw an Apu or a pricey CPU in while never thinking of CPU mining.

i feel lucky to have
 three 3900x
one threadripper all running

and three more boards ready to upgrade .

no psu cost
no ram cost
only one mobo purchased.

i will have seven running for under 2000. roi will be 150-200 days.

pretty quiet and will warm the basement for winter.



ROI 150 - 200 days? No way, never, noooo. Which calculator you are using?  Roll Eyes
I'm not sure what the thread ripper makes but currently a 3900x (without electricity being taken into consideration) is making around $36-40 a month let's say 7 months is 200 days (it isn't) he's at $840 revenue for the three and then the thread ripper will be probably making this closer to $1000, so maybe a 400 day roi for $2,000 but remember he's already gotten tons of use out of these boards and CPU as gpu mining host and they will carry use and value for years.


they are quiet and reduce my heating bill from 240 to 100 a month.  so 140 x 4 = 560 extra..


 The boards  are not free they  are paid off and I have a hand full of cards that are paid off  they add to the profit.  

  Yeah 150 200 is too good  it is more like 350 days.

  My power bill for this gear is low enough that I can hold all the coin I make .  Since it is all nicehash  It is btc and simply sits in place.

Yesterday I grabbed a ryzen 7 3700x   for 97 bucks. I had a credit on amazon.

People have to realize as long as xmr/monero  changes al-gore-rhythms   every six months  chasing with other hash  is a fail.

Down the road I can consider getting this

https://www.newegg.com/p/N82E16813157902?Item=N82E16813157902&Description=trx40&cm_re=trx40-_-13-157-902-_-Product


and this

https://www.newegg.com/amd-ryzen-threadripper-3960x/p/N82E16819113619?Description=threadripper%203960x&cm_re=threadripper_3960x-_-19-113-619-_-Product


I have all the other parts.   so the 1499 + 459 = 1958  is all I would spend.

Based on past history   the threadripper 3960x will be under 1000 by summer.

the 1920x is now 200-279 it came out over 500
the 1950x is now  500-700 it came out over 1000

the 2950x is now 679 at newegg

https://www.newegg.com/amd-ryzen-threadripper-2950x/p/N82E16819113542?Description=threadripper%202950x&cm_re=threadripper_2950x-_-19-113-542-_-Product

the 2970x is 1250 at newegg
https://www.newegg.com/amd-ryzen-threadripper-2970wx/p/N82E16819113546?Description=threadripper%202970x&cm_re=threadripper_2970x-_-19-113-546-_-Product

it dropped  from over 2000

Usually such calculating ought to multiply x2-x3. Nowadays any coin with profit getting huge hashes really fast. And ROI becoming 250, 350, 450...
But 3 CPU without any additional expences are the nice choice for home PCs.

You can build such rig just for fun. Its too expensive to build such a rig with new mb, CPU, etc. If you just want to test it in easy and cheap way - try to buy at aliexpress used components.

Multi CPU "rigs" don't exist. Multi CPU motherboards and the CPUs that support them
are very expensive and support only a few CPUs.

Intel Phi compute modules can be installed like GPUs but are also very expensive.

The closest you can get to a CPU mining rig is a Ryzen R9 or Threadripper with 16 to 32
cores and double the threads. There could even be a 64 core TR in the near future.

As far as cost goes the more systems you build the more the overhead in motherboard, RAM,
PSU, SSD  etc. Fewer systems with bigger CPUs would be more cost effective but near the
high end the CPU prices rise quicker negating the overhead savings of fewer systems.

You'll have to find the sweet spot.

as of right now i do mine on my cpu when im using it, which is 24/7, i was just wounder cause i could get my hands on 2 AMD FX 6 cores at no cost to me and i was just wanted to see if i could use them to mine without the need for a whole other motherboard setup,  been saving for rx 480 but winter been brutal on my electic bill been hard to save, thanks for all the information yins where very helpfull
