Cheap cpu mining rig

[Somerandomtechyboi]

Budget (including currency): pref ~5jt rp aka 330$ but absolute max ~10jt rp or 660$

Country: indonesia

Games, programs or workloads that it will be used for: mining though might convert into a personal rig if it doesnt work out

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): pref parts not abroad so less shipping costs and taxes

 

Basically my mom is interested in mining crypto and she kinda resparked my interest abit in crypto mining

 

Gpu prices are through the roof so sht like tesla k80 on ebay are now really expensive when they are only going for ~200$ a year or 2 ago so im gonna go for cpu mining instead

 

Platforms that im considering are 775, 1366, 2011(-3). On 775 there are xeons with 12mb L2 cache, 1366 the xeons have 12mb L3 cache but i think only 2mb L2 cache, 2011 has upto 35mb L3 cache on the 12 core cpus like e5 2651 v2, havent looked at 2011-3 that much since its pretty expensive

 

Are 775 xeons with 12mb L2 cache superior to 1366 xeons with 12mb L3 cache but only 2mb L2 cache? Cause for all i know cpu mining relies on cpu cache

 

How much does clockspeed affect mining performance? Cause i think cache speed is determined by cpu clockspeed

 

Also i might consider powering it with solar panels so i dont have to worry too much about power bills so basically guaranteed roi but roi is gonna take awhile

Lol no.
Mining on a 1060 6GB 20Mh/s
Mining on a CPU Ryzen 3700X 0,2Kh/s

 

You would need 100 000 of those CPU to even come close to a very low end GPU.
So get this out of your head, there is no CPU good enough to mine with profit.

Looking at crypto that can only be mined with cpus .-.

Fun thing with those is that the ONLY class of cpu that is profitable for that are current gen ryzen ones due to their high performance and efficiency.

 

None of the platforms you listed are going to make you money. That and the profit margin is so so so small on cpu coins like nicehash it would take 5 years to break even on a used ryzen 1600 200usd motherboard ram combo thing. Which is currently the most budget friendly option to go.

 

 

So in other words don't it's by far not worth it. ALL CPUS YOU LISTED WILL LOSE YOU MONEY. They are FAR TOO POWER HUNGRY.

If i powered them with solar panels then what kind of profit can i expect?

 

I can find some solar panels for ~33$ which are advertised as "100wp" or whatever tf that means

A 100 wp (watt panel) refers to a solar photovoltaic module that is rated 100 watts. This means that it has a power output of up to 100 watts of DC output under optimal conditions.

 

Are you sure you need only one of those????

 

Coming back to your main question

All those CPUs that you mentioned above are significantly older and based on an "ancient architecture". It would take you ages to earn what you will spend on this rig.

The profit of well if lucky with the xeon 7 cents a day ish. That computer is basically going to be dead before it ever returns a profit.

Just don't bother it's not worth it but I feel like you are just wanting to do this anyways here is a long why not.

 

Those solar panels will be used ones and only produce 100w/h IN OPTIMAL CONDITIONS. Which means not perfectly direct harsh sunlight. Which depending on where you are is maybe 3-4hours of the day.

 

Now you'll need enough power so that it works ALWAYS which is not a guarantee and you need somewhere to store power so it works even when there is no sunlight. A battery pack that is decent is easily 1200$ which can get you about 1.5kw. This would be enough to run a e5 2651v2 system IF LUCKY for about 10 hours fully charged.

 

Now keep in mind these batteries are usually rated for about 1000 charge cycles and degrade over time so 3 years in that 10 hours can easily be only 7.

 

Now you also need inverters and everything so the solar energy can be converted to a power pack. A decent one is quickly 150-250$ depending on how many solar panels you need.

 

You also need to have the panels in a optimal position so mounting and installation cost has to be factored in too. So another 100-300 slapped on.

 

So basically to do it off grid would be easily 1700$ at a minimum. I am going to use a ryzen 1600 here for an example which WITHOUT ELECTRICITY COST AT THIS MOMENT (it will get worse over time) makes you 20cents a day. Now lets say the ryzen rig is 350$ so you have a investment of 2050$. 2050/0.2= 10250 DAYS before you get a return of investment. That is 28 years aka more than the return time for a solar installation. This is assuming the 1600's income stays the same which it won't it will only get worse.

 

So yeah it's going to take AT LEAST 30 YEARS BEFORE YOU START MAKING MONEY. It's literally more profitable to just get a solar installation for your house.

 

This does not include the fact that NONE of this equipment is going to last that 30 years.

 

So tl;dr you are never going to make money even with free electricity.

I roughly calculated it. With a solar installation that is enough to charge a battery and all that crap it's 28 years at current prices with a ryzen 1600 as that already does double what e5 2561 will do.

I think the point may be that you have a PC that can mine a bit, learn some things and just enjoy a bit of mining fun

Not to make money necessarily.

Well shit, gotta find another way to power it i guess or spend tons on a solar system, atleast itll be multifunctional but tbh its prob not worth it just for this project

 

I could try stirling engines but then id have to build one, though i do have isopropyl alcohol and a liter is only 1$, too bad shipping screws me over

 

I could also do manual power aka just power it via a freaking bike, good for excersize but prob not gonna be very practical

 

Well shit ive run out of options other than the manual power one

And this also confirms it

 

Guess ill just try convincing mom to fund my computer "buisness" thingy abit more so i guess should just fix a bunch of dead boards with cleaning, bga rework tools, etc. Then sell em off

 

Also attempt to build ultrabudget pcs but prob failing miserably at it ;-;

 

 

Welp unless anyones got some extra useful info then no point responding to this thread just to save you abit of time cause i dont think ill bother mining

At that point i might aswell just fold

If she wants to do bitcoin stuff go do some bitcoin trading. Just remember PULL OUT THE MOMENT YOU MAKE A DECENT BIT OF PROFIT (aka 20%). Because the amount of people that just ride and die is too high :p.

Indeed better to help than to do meaningless mining. I mean there is little to learn about it. It's just set up a piece of software hit go and it's going.
