Best hardware for monero rig ? (RandomX)

[burtcoleman86]

Hi

When RandomX is active on monero, what would be the best 450$ setup? (MB/CPU/RAM etc.)

AMD Ryzen 3900x is the best CPU imo (it's great at cn/r also), it has a large cache that both CN/R and RandomX loves, totally 70 MB. You don't need much RAM or a fancy motherboard (x370/x470/b350 is really enough).

As for motherboard i would go with the msi B450 Tomahawk or the msi B450-a pro but all msi b450 boards have the bios button.
Easy to flash the motherboards without cpus.

what type of ram for 55?

i have bought a 190€ board , because was the cheapest. and now price of 3900x is 780€.

price in europe skyrocketing every day

Is there any dual CPU boards for Ryzen 9 3900x?

Its not needed with 16 gb ram so you can just pick up  for example 2x4gb corsair lpx 2666 or something similar,  whats crucial is that you get 2 sticks of ram.

Is there any dual CPU boards for Ryzen 9 3900x?

No dual socket for am4 but i read some rumour about possibly on the new high end threadripper, will be intresting to see!

I already have a Ryzen 1700, I mined a lot of XMR in the past and I pay the CPU with it
It's very tempting to change for a Ryzen 9 3900, it's a monster, but I don't know if I'll do because electricity in my country is very expensive at the moment and probably will not worth, but as an old miner, it's tempting me everytime

Thanks for the input guys! First time building a AMD CPU computer. Only built Intel before..

The B450 was cheap as well, so i think i will go with that one. Thanks.

Why do you recommend such expensive board when you can get something like 40euro board for Ryzen9? The same goes for PSU prices? .. It has huge impacts on the ROI of the setup.

Yes it has impact of ROI.
What board can you get for 40 euro especially with decent enough vrm for ryzen 9 3900?
Not even the a320 boards goes for 40 euros...........

PSU prices i see it like driving a new mercedes thru europe versus driving a old saab 900....
My point being you get what you pay for, this is not for a gaming machine  running 3 hours a day, mining we want 24h uptime 365 days a year in the best of worlds..

Its just my take on this.

MSI A320M PRO-VD/S V2 - this board costs roughly 40euros in my country. Ryzen has 105 TDP, so with all things considered 300W psu should be enough.

I am a miner since 2016, i have decently large farm for GPU mining, just never CPU mined myself. I have always bought the cheapest rams, hdd, motherboards and never had any issues. Do you have definite proof, statistics, that cheaper motherboards are more faulty than the more expensive ones? (they have a lot of useless components that can get faulty that you absolutely dont need for mining).

I have different philosophy and that is to have as much as capital allocated to assets that actually atribute to hashrate. Maybe this is not evident if you build one rig, but when you built 20 of them, by thinking like this, it makes a huge difference.

I havent looked up any statistics if cheaper motherboards are more faulty.

But what i want to express is not cheaper or more expensive but what the motherboard is designed for , example the vrms , putting a 3900x on the MSI A320M motheboard is just asking for trouble, no heatsink on the vrms. Simply said A320s  are not designed for this amount of highend highcurrent cpus.

If you wanna go for the msi a320s then i wouldnt go with anything else then 3600s.

Here you have some intresting reading to do about am4 motherboards and vrms etc etc:

Think the best setup is need to get motherboard which supports multiple gpu 6+
That way you wont waste your money, just building a CPU rig.
I would go for Biostar TB350 and Ryzen9 3900x
Add some Nvidia 1660 ti or AMD RX570. Do CPU and GPU mining at the same time. Use CPU to mine Monero and with GPUs for example mine Ethereum.

That’s one of the things I am looking into, since I have 15 RX 580 8 GB.
The Ryzen9 3900x is a bit expensive where I live, but the TR 1920x or Ryzen5 3600 is cheap.

So thinking 3xRyzen5 3600 and B450 Tomahawk with 5 GPUs on each.

Sure thanks for feedback, the link is full of information. Will check on it, for sure you can install heatsink yourself
