hello guys , I am looking for some help from the pro miners in here
I am currently trying to run a 5 GPU mining rig but I am having problems to get it running all 5 cards
my rig is as follows
2 unit of power supply , 1st 1200w corsair powering the board and 3 cards , and the 2nd 850w cooler master powering the other 2 cards
motherboard asus rog crosshair v formula , the board have 4 pcie x16 slots and 1 pcie x1
cpu amd fx 8150
memory 16gb corsair dominators
ssd H.D.D
5 x vga cards asus strix gtx 1080 ti running on riser cards ver 8 (the newest riser cards)
I have tested all 5 cards separetly and all 5 riser cards separetly and all are working fine
so far I can have the rig running with 3 cards with no problems
the problem starts with adding the other 2 cards , the motherboard recognize all 5 cards but I get the error code 43 on windows
on 2 of the cards , I need to mention that the 2 cards that get the error code 43 are inserted on the pcie x1 slot and pcie x8 slot
after several tries of pluging and unplugging and switching cards places and combination I find out that any cards inserted on that 2 specific slots
are always having there driver crash on windows and that gives the error 43
I have also tested running only one card on these slots and it manages to get the windows up but it immediately crash if I try to put any load
on the vga card
right now I am convinced that the problem is driver related , I am running NVidia latest driver 388.43
I have used the vga ddu uninstaller and completely removed the driver and then reinstalled it but still have the same problem running any cards
on these slots
I have tried every possible settings on the motherboard bios and I have tried flashing the bios again but still no luck
so what I am looking for in here is any help about the NVidia drivers that can get me to run all 5 cards without the error code 43
or any specific settings on the bios if u think that the problem is bios related (my bios doesn't have an option for enable 4g decoding or switching the pcie gen1 gen 2 its running on pcie gen 2 by default)
note : at some point after several tries I have managed to get the system up with 4 cards and started mining with them for few hours but after restarting the system to add the 5th card I can no longer get 4
cards working again
if anyone using this specific motherboard or have any experience with it can you please help
Maybe not enough system resources, but you get the Code 43 and not Code 12.
Read page 2-14 user guide for your motherboard. It is described IRQ used in conjunction with various devices. Might help disabling USB 3.0 and onboard sound card.
