i am beginning to think that the gigabyte board was a bad choice and as i can not set gen 1 for pci-e i probably will replace it
most of you who run rigs have intel based boards
can someone provide info on what amd or intel board that supports 6/7 gpu and works
if i plug the cards (3) directly into the motherboard it mines just fine and i get around 220 sol with 3x rx480 on silentarmy 5
However as soon as i plug in just 1 card on a riser the system doesn’t boot(tried all slots)
If i have 1 card in PCIe 1 and plug in a card with a riser the system boots up but only the card in PCIe is detected.
If i add another card the system goes dead and will not boot.
I have a Asrock h81 pro btc. And I have been struggling to get 6 GPUs running for like 11 days, before I figured out that 14 out of 15 raisers are dead.
Invest some research and a few bucks more to get good quality raisers. cryptomined is selling good ones here on the forums.
so you think it is the risers?
I thought i had bought good ones as 6 did cost like $55
They look like they are the same as the ones cryptomined is using.
One more reason i think it is the board not supporting risers at all.
I have no way to for example set PCIe to Gen1 or in fact do any settings on PCIe/PCI
I can use ether GEN1 or GEN2 but the Auto setting fails. Not sure if that is the big deal here. Just for fun, try to clear the CMOS with the jumper on the board. That helped my board to start up without troubles.
I could figure out a 100% for sure that my raisers are faulty. I cutted out one of the x1 slots on the board and placed a GPU right in there, and the system works. So it had to be those.
Else the raisers just cause bananas on the board. Code 12s, 13s and 43s in the device manager. Or not detecting the cards at all, causing 173% hyper fan speed on the GPUs, etc.
Do your raisers have a version number on them? Mine are version 003. V004 are told to work. I bought some V006 just today. Hope those arrive within a few days.
Have not seen any kind of mirroring in such a case. 2 Sol/s is pretty bad. As the raisers are V6 and have solid solderings, my next guess would be the mainboard, or more specific the BIOS. Are you running the latest BIOS? I think it should be version F2 for your board.
Yes updated to F2, no changes
I think the 2Sol is a problem within the miner programming.
I forgot to change the use on the start sequence from -use 0,1,2,3,4,5 to 0,1 to test the 2 cards and the miner did show 3 gpu and mined 2sol on the 3rd, 0 on the second gpu which is/ would be the card on the riser
yep not much of setting
i assume the setting for Gen runs on auto and as it seems that auto fails with setting the correct Gen this board is useless and will not work with risers
