Does it make any sense to use a old core i3 motherboard to mine cryptocurrency with up to 6x graphic cards? Is there anyone here using first gen or second gen core iseries to mine crypto? I found them very cheap here than 6th, 7th gen motherboards

That makes a lot of sense, because I myself am currently still using an old core i3 motherboard (4th gen) with a mix of 8GB DDR3L ram and also using an SSD with a capacity of 1TB which allows me to do anything in crypto including mining some very good tokens.

There is a huge difference between a i3 4th gen and a i3 2nd gen, anyways I have a mining rig with 5 GPUs running on a old Xeon dell desktop and the whole thing is working pretty fine, power draw is limited since I don't use the CPU for mining, only the graphic cards draws needed watts

yep works fine i have x58 with i7 920 still working with no issue but i cant install 5gpu, it doesnt boot with 5, but with 4 gpus no problem.

It should work with 5 gpu if 5 pcie slots are available, I have a core i7 920 too but with asus motherboard and it has five pcie slots, I was able to run 5 RX580 8gb with 1200watt power supply on the motherboard, I suggest you upgrade the BIOS to the lastest

I've used as old a as a P4 for GPU mining.

Update the BIOS as others have said, but also check the BIOS config to make sure all
PCIe slots are enabled. A Pentium or Celeron may not have enough PCIe lanes
to support all the slots on the motherboard, but Core should be ok.

If a system fails to boot when a 5th card is added my first suspicion would be power.
If the port was disabled I would expect the system to boot but only recognize 4 cards.

Heck ive got a couple rigs running G1840 celerons from 2014.
Mining with linux.6 gpus each (570-8gb) - 190mhs per rig.

It doesn`t matter for the main part of coins what CPU you have. I`m using Athlon x2 and it`s enough. Someone use socket 775 CPU and it mines normally too.

no it is not bios. looks like mine is parallel connected with 1x slot i guess. some mobos doing that :( it has 3 16x and 2 1x slots

p35 motherboard with ddr2 and q8400 there is also q6600 and q9550 LOL.. this rig is already a teenager  :D

older dual core affects hashrate, so i throw them away.

You can mine with pretty much any CPU out there. PCIe if I recall came out in 2005 or so. So most CPUs made after 2005 should be adequate to mine. I got a rig which has an Sempron processor, yes Sempron. Most of you guys don't even know what it is probably.

Sempron is a cheap processor that I paid maybe $2 on eBay which is single core (yes single core) and most likely an iPhone has more power than this actual CPU. I used it to mine with 6 GPUs no problem. The issue was only during installation and start-up. Took forever to install Windows 10 on that processor and takes maybe a good 10 minutes to load Windows 10. Once its running then its rock solid stable.

Asus P5N32 E-SLI mobo here.   4GB of DDR2-667 memory and a core 2 quad cpu installed.
Works and mines fine with either Win 10 or Xubuntu 18.04.

I have quite a few g3900 intel cpu's with 2gb sticks of ddr3 ram that work fine running smos.

That is 3rd gen

some rigs with the g3900

Yes it makes lot of sense because first gen core i3 in my country costs 40$ with the whole case, I mean a complete desktop PC lol so it's a good choice for mining crypto if the motherboard have enough pcie slot

I still use a dual core motherboard to mine Ethereum, you will be fine since they all have pcie slots, all you need to do is update bios and buy some risers, my dual core is old CPUs after pentium 4 lol, see how old this is ? They use ddr2 rams lol

well never try 2nd gen, but 4th gen is good enough to mine with 8 gpus, 2th gen to old,the motherboard quite worry rather than cpu itself

its cheap but the problem doesnt par with the pain, better to buy skylake celeron only cost 30$, and mobo 60$,

I have no idea what you meant by this but I can tell you that I'm running a core i3 2nd gen with 6x graphic cards right now and it's working quietly with no problem, some people are even using old fail core motherboard to mine, all it takes is the GPUs itself not the mobo, as far as the mobo detect the gpus there is nothing stopping it the work
