i plan to make a zcash mining rig with nVidia Cards. can someone tell me which motherboard, poweradapter and cpu is recommended for this usage? i think i will make a 4 or a 6card rig, depends on costs beside the cards.
The rest is my opinion and how (with the help of a friend) my rig is built.
128gb SSD HD
4gb ram ( I have 8gb since run a VB for Linux for Zwallet)
you truly only need a 2 core processor - if you go more its because you wanted to spend more $$$$
O/S either Win10 64b or Linux (you currently need Linux if you want a zwallet)
Mobo - depends on how many cards you want to run, if 4, then will work as long as they have as many pci slots has cards. Now 6 or 7 or 8 cards then you want something high end like the z97 or equivalent.
PSU, find the card you want, then how many you are going to run, then find the watts needed to run each card then multiply that by 1.75 then add 225 for mobo, HD and risers, fans.
The x1.75 is so that you find the sweet spot in your PSU and to avoid spikes and over heating. There are tons of posting about the PSU sweet spots, and if it matters. Again my opinion it does matter.
thanks alot, very informative and helpful answer. i didnt know that a 8card nVidia rig is possible. usually most of all rigs are with 6 cards. i tought the reason therefore is, that 8 cards dont run stable - ist this true?
if 8 card rigs working fine, can you recommend me a the mobo model/type/brand which is running with 8 nVidia cards?
i will use nVidia cause i got a couple of them second hand for a good price. different models, but that shouldnt be a problem, right?
PSU, Mainboard, CPU and GPUs. Did i miss something?
what OS u reccomend? windows should be better for nVidia cause of the drivers, right?
well, as this is my first rig build my myself i think 6 mobo mainboard is the best choice for me. so all i need is a mobo with 6 “PCI-e 16x” slots, correct? can you reccomend me a price worth and good mobo for my use?
Many people use the Asrock H81 BTC pro R2.0 (I have 2 myself)… has 6 pci-e slots, and as the name implies it was made for mining in mind. It’s pretty inexpensive if you live in the US. It uses socket LGA1150, I bought a cheap Pentium G3258 for $60.
As for PSU, depending on availability and where you live, the EVGA G2 series is highly regarded (I have one myself)… if you want to run 4-6 GPU’s, the most high powered one available is 1600 watts for the G2 series. I have 4x R9 Fury’s… roughly 320 watts each… plus the mobo and cpu, 1600 watts should be very comfortable for that load(for my setup at least… though if I added more cards the PSU would be too stressed perhaps…), generally estimating… do your own research, make your own decisions, but just passing a long the info.
I tried the m.2 extension and it didnt work for me when I tried it on msi z97 gaming 5, the 1-3 adapter worked but the OS would only use 7 cards. I have heard you need to use windows 10 enterprise to maybe get 8 cards working, but I have not had the time to try that yet.
I read a thread about someone wanting to try with 8 cards using that - but he has yet to actually try LOL
I have not read about anyone using it and getting it to work… though I suppose it can work somehow
someone also told me that 7 Nvidia cards wouldnt work for them
Im curious to try myself, considering getting some 1070s
also want to try vega when it comes out
when is ryzen and boards coming out for sale?
i notice hte biostar board has 7 pcie slots? how many pcie lanes does the chipset have?
I have recently built a x6 GTX1070 rig and it is mining at roughly 2700-2800 sol/s. That is with GPUs overclocked. Out of the box you can expect ~2450 sol/s. For anyone interested, i could build one for you for $3300, shipped. Continental US only.
I’ll provide some help and instructions to get it up and running on windows. You will have manufacturer’s warranty on components.
