Title: 12 GPU Mining Rig build | Need your Advice! Post by: VulvaSniffer on December 26, 2017, 07:53:01 AM Hi Guys, i need your input on my Rig. my rig will consist of the following:
SMOS CPU PENTIUM G4400 Motherboard ASROCK H110 Pro BTC+ RAM GSKILL 8gb DDR4 PSU 2x 2000w 95+ gold (i tried buying 2x 1650w but there are no stocks in my area!) Dual PSU link Ver. 7 Sata powered Risers 128Gb M.2 SSD 12x Gigabyte GTX1070 all single 8-pin 10x Fans in the Rack I also bought WattMeter/Killwatt Is my 2 PSU enough to power those 12 GPU? i guess i need to pay attention into daisy chaining them. i intend to power 2 risers per VGA cable, is that okay? Thanks in advance and looking forward. Title: Re: 12 GPU Mining Rig build | Need your Advice!

The main thing is to use quality cables. Title: Re: 12 GPU Mining Rig build | Need your Advice! Post by: 0xcosmos on December 26, 2017, 10:17:04 AM very good rig list
btw you do not need 8gb 4gb will do anyway use one molex cable for two gpu and your rig will be fine Title: Re: 12 GPU Mining Rig build | Need your Advice!

What you mean use 1 molex cable for 2 gpu? isn't it better to use 1 pcie cable per gpu to better spread load and also not to overheat cables? can you please explain on this?

They probably mean 2 molex on 1 strand for 2 risers. Title: Re: 12 GPU Mining Rig build | Need your Advice!

They probably mean 2 molex on 1 strand for 2 risers. i see. all my risers are sata powered and yes, i've been planing to use 2 on 1 strand. Thanks for clearing that up!

Anyway, i'm thinking if i should use SMOS or use just stay with NiceHash. Since the 8 limit GPU on windows has already been increased by the creators update then i might as well try that and do the OC and Undervolting using the Nvidia Inspector if MSI afterburn or others will not support 12GPU OC |
