3990x for mining

[andy.arden]

Hey guys, any experiences with 3990x cpu? Want to build a pc i am going to use at other stuff but wondering if this cpu i can use to mine something that will make this pay a bit for what is it worth. Any suggestions will be truly appreciate. Thanks in advance.

my 3970x thread-ripper earns 1.50 to 1.80 a day mining ⛏ 24/7

i downclocked the freq to 3200
i downclocked the volts to 1.1

i use nicehash to mine xmr with it.

i use 128gb ram
i use a 500 gb aorus 4th gen nvme.2

i use various gpus.

1080
1080ti
1660
1660ti

amd 5500 xt
amd 5600 xt
amd 5700 xt
amd 5700

all have been run on this rig at one time or another

i use an asus prime mobo the 449 price model
i use a corsair 1500 psu

and i use a large bequiet air cooled cooler vs water block keeps gear at about 58c

not good idea because mb also very expensive for that cpu. instead buy 3900. For that money you can buy 2 3900 and 2 mb. and will be ease to sell you will not loose to much value.

It is a costly build but he did say he wanted to do other work.

I have all the parts above except I went for the cheap cpu the 3970x

build above = 4745 no case or psu.



my builds us the 3960x and the 3970 x

1299 + 1699 = 2998 2 cpus.

2292 for 2 rigs mobos ram ssds etc

so I went for 5290 for 2 rigs.

I get 23+29 = 52 for hashing xmr



I have 4 3900 rigs. they do 12 easy so 4 x 12 = 48 for hashing

cost about. 1100 each to build or 4400

Threadripper 3990x CPU are the best for Monero (RandomX ) Algorithm presently followed by EPYC high end CPU, to cut the story short you will be able to earn 2.92$ per day mining with 3990x CPU presently, just make sure your setup has good air flow or enough cooling setup

Anyone with a big CPU should consider mining during down time. But if buying a CPU for mining, I agee, the 3900X
is more cost effective. It's also great for a combo CPU/GPU rig.

Is it possible to mine both on the same rig ( my gaming rig ) with the CPU (considering buying next Ryzen 5900 in 1 month for gaming + 3D rendering) and the GPU (1080TI for now, 3080 when they are in stock) ?

Isn't it 'too much' mining both with CPU and GPU at the same time on the same Rig ?

Totally possible, a lot of people mine with CPU + GPU to maximize the profits and waste less power
Here in my personal rig I have a 5700xt and a 1660 super, and with a Ryzen 1700 (old, but good), and I leave the GPUs mining with Nicehash and I mine Veruscoins with CPU, it's more profitable for me than XMR

It's easy to have both mining, no problem, just be sure to have a good PSU and a good airflow

Thanks !
But is it worth it, with the TDP on an high end CPU, compared to adding another GPU ?
For cooling,  I have a custom full EK wc loop on both GPU + CPU, with a 420 mm rad, I guess it could be enough
And a 850W Asus Rog Thor PSU, juste for the ryzen and the future 3800

Considering AMD is unveiling Zen 3 next Thursday, its probably best to wait and see what the new processors and prices will be before seriously considering anything.

This is up to you  
You can enter on https://www.nicehash.com/profitability-calculator and put your electricity rate and the CPU, you'll have a estimate of profits

Most people only use low power CPUs like celeron to consume less power and the rig will be more profitable, but for some users who have a rig/PC and will use daily, it's interesting to have a strong CPU and win some money
This is what I do

You can tweak the CPU to have a higher hashrate and less voltage
