I’ll just put it out there.
I watch the videos and get more confused on a direction to go than when I started.
I had wanted to build a GPU rig, but now watched that GPU is no longer the way to go.
To get into the mining, I don’t have a ton to invest (silently… wife is watching).
Not concerned about fast ROI, but residual. Keep the money coming in, then re-invest.
If you were limited on funds, where would you start?
Hi Dubkell,
I am also quite new into mining, just started this September 2021.
My advice (this is what I have done) start for a gamer pc with one or two GPU cards and use Nicehash.
you will start learning and getting money in.
Then, with time when you feel more confident, and read a lot, and watch a log of YouTube videos lol, you can add some more GPU cards with an external stand and maybe get another pc and more GPU’s and then maybe later move to an ISIC…
This is my personal experience…and what I advise.

thanks for that!
Was originally plotting on piecing together a rig as money came in… start with the case and power, add the motherboard, cpu, memory… then it gets expensive. 
If you are CPU mining, then obviously you have a computer. Try adding one video card (choose a brand and model whose GPU draws < 200 watts)/
If in windows, use afterburner to learn about Power Level, Core Clock and Memory Clock and their frequencies. Download Miner software (preferrably from Github) such as T-Rex, GMiner, Team Read Miner, LoLMiner whichever supports your coin choice. Config the batch files and get mining.
If you use HiveOS or SimpleMiner, simply configure your Coin, wallet, and Miner settings and away you go. The OS will download and run the Miner you choose. No need to download.
Overclocking: The goal is to use less POWER and get a good hashrate. Start with a moderate Power Level and lower the Core Clock until Mining starts to falter. That would be around 1000 Mhz. This works for both windows and Linux systems. Today’s T=Rex lets you enter a specific core clock frequency. I suggest 1200 but not less than 1000. Once you have that set, lower the Power Level until the Core Clock frequency starts to drop. Then, raise it slightly…this should be between 60%-70% or less than the GPU’s specified power from the manufacturer. Finally, the Memory Clock is the one that will really increase your hashrate. As you raise it, the hashrate increases until either the GPU crashes or you start getting invalid shares.
As you mine, if your computer crashes every few hours, you will need to lower the Memory clock some more. The ideal setting is not the MAX hash you can get, but one that runs days without crashing.
Temperatures change throughout the day so you will need settings that work during the hottest part of the day and still work during the coldest part of the day.
So, start with just the video card you have in your CPU mining computer or one that works for mining. Adjust settings (they are different for each card, and each coin). Experiment with OC settings in HiveOS or in Afterburner until you get the hang of the frequencies and levels. Cooler is better.
Graduate to a 2nd card after you have mastered the Art of GPU mining. Then consider purchasing components to build a rig that will accept several cards. There’s much more to learn, like the 80% power rule, limits on Watts per connector, watts per cable, and the number of cables by wattage of power supply.
KiloHash per Watt is the best indicator of efficiency. 400 kh/w is good, 500 kh/w is better, and now 600 kh/w is best.
Good Luck
