Sorry, what's the point of this comparison? You're basically saying it's not worth it to invest in standard hardware when there's something like the octominer around.

Edit: at first I thought you were contra-octominer because you said '100 mobos without a failure', but now it seems like you trying to convince me octominers are actually worth it, so it looks like you are pro-octominer now. Edit2 because I like spreadsheets, too: Obviously the idle wattage of 160 old computers is higher then 80 computers with modern hardware of 2017/2018. But for 45k USD saved in initial costs, you know. I'm not trying to prove anything here, its just. You have your build, and that's actually my build. Well, not in this scale unfortunately, but smaller:).

Sorry that I have to attack you a bit but your comparison is out of any spheres. I’m not anti octo instead I’m already a fan and defend them against people who say their are expensive. Your build doesn’t scale. Pcie extender cards don’t scale. Old mainboards don’t scale. I had it all. MonaCoin MONA Mining Dedicated Server.

GA9xx series, 4x gpu rigs, 5x gpu rigs. I tried all, 1050 with 500w PSUs on and on. It’s pretty useless to think on your level of scale. You are a hobby miner with a (sorry) absolute amateur mining hardware rig. No professional/industrial farm is using any of your suggested hardware.

I’m on the scale of 1k gpus and doubling if the prices are back to usual. I know what means to be full time mining and what the consequences of unreliable old hardware are. Even with 10 rigs which crash here and there you have sleepless nights. You’re Hardware simply won’t scale and is not compareable.

No worries, I don't take anything offensive if the arguments are invalid by my POV. Not sure what you mean when you say this or that don't scale. This is a real world example and I did build a 40 GPU rig based on my chart as an experiment (actually with 4 GPUs per computer tho, not 6, this was my design fault; 6 is tested and works too with the computers that were used), then moved that rig to Romania to its new owner where electricity is neglectable, unlike initial building costs (modern hardware over there seems to be even MORE expensive then it already is, here in the rest of Europe).

It's a budget build and for what it's worth, I call it a success. Build 1 or 50 computers this way (each with 4-6 GPUs), will work the same. I though that IS the definition of scaling.

Pcie extender cards don’t scale Scale? Like cascading them (put them in series)? Never said this would work. The thing is you pop them into a computer with a chipset that is capable (!) off handling that many PCI-E lanes you are about to use, and thats it. So no, PCI-E Expansion cards don't scale. Because they don't have to scale at all.

You are a hobby miner with a (sorry) absolute amateur mining hardware rig Can't remember where I stated this is the one and only rig I have or built (it's not). Guess I have to take 'amateur mining hardware rig' when researchingpersonally, since you said you have to 'attack me' now. However, GPUs don't care if they reside in a 250$ Z270 Mainboard or a fucking gameboy, as long as it works. But hey I'm just a random (3-digits figure) GPU pleb dealing with hardware for decades, not even 1k like you do, so what do I know. No professional/industrial farm is using any of your suggested hardware.

A real mining company (with staff) would probably run new hardware, I have to agree there (as an employee it's not 'your' money anyway that you are spending on stuff, so just go with what the most easy stuff you can acquire and run, right?), if you scroll up abit you will see I said the octominer is 'probably more [for] professional miners'. If it's a personal farm, got some time on your hands and want to maximize profits I'd say. Never say never. You started crunching numbers and I love to do so, too, so I jumped in.

The length of this posting might suggest the opposite - but I didn't try to prove anything here (as said before). I though we have this conversation on how varient builds and strategies all have their place (hence I asked what the point of your comparison is, I wasn't being sarcastic or anything trying to bring it down, I just didn't understand it because your chart basically shows its actually pretty worth it to consider octominers instead of standard hardware), but if you take it offensively and have the feeling you have to 'attack me' or anything, then I apologize. Enough offtopic here from my side in this thread, looking forward to see this nice hardware going mainstream, good luck.

Does enable all algorithm available in MiningPoolHub more profitable? I just finished a 48h test run and it's not worth it running after the coin with the highester (or a higher) profitability, be it 'auto switching algos' or what I have just tested: I used to mine DigiByte and got 600-800 Coins with one particular rig per 24h, while it's profitability was really down (like 0.2).

That time, Zclassic was nearly all the time the no. 1 in profitability (0.4-0.6). So I pointed this rig for nearly 2 days straight to Zclassic (and it remained constantly having a much higher profitability then DGB that time). Now guess what? I did 615 DGB/day, auto-converting this Zclassic into DGB. TL;DR: screw profitability.

BridgeCoin BCO Miner Computer. Pick the coin you want (as long as it's not one of the bottom 10 lol). End of story.

1) A MotherBoard - A motherboard is the brain of the computer and is what you build everything onto - the base of your mining rig. The main feature is the number of GPU slots it has as this will determine how many graphics cards or GPU's it can fit - and in the end your total hashing power. 3 PCI Express slots will mean you can fit 3 GPUs. A PCI Express slot is a connection port on the motherboard that are often coloured white but can be beige - you can get other types of slots but most GPU's work on a PCI express. 3) Hard Drive - The hard drive stores operating system and software for mining. A standard SSD drive will do, but we install a specialized SSD known as M.2 which can be up to 24 times faster than a standard SSD. An SSD hard drive is just a storage device and is called solid state as there aren't moving bits which can break.

We standardize at 128GB for the size. If you are planning to download the entire blockchain or other hard drive intensive software of programs, we have larger sizes of M.2 for consideration.
