Can´t mine with 3th GPU - MoBo Gigabyte GA-B75-DS3V

[cirooc]

Hi guys!

I can mining with 2 GPS, but when I connect the 3th, my HiveOS identify the GPU model but not show the memory size (and not work):

My setup:

• MoBo Gigabyte GA-B75-DS3V
• 2gb RAM
• Intel Celeron G530 2,4GHz
• Flashdisc with HiveOS version 0.6-204
• Kernel 5.4.0-hiveos #108
• 600w PSU

I tried to:

• Change all risers
• Change PCI slot
• Tried to conect just de 3th GPU (and show the same error/problem)

At bios I changed:

• set to Gen2 at “miscellaneous settings”
• Disable audio
• At “Other PCI Device ROM Priority” I changed to LEGACY

There is not at my MoBo bios:

• Above 4G decoding to enable
• CMS Support do disable

I suspect that can be problem at GPU, what do you guy think?

Thanks a lot!

Hi, have you solved this? I have a Chinese mobo with the same chip and it’s recognising all the GPUs (partially) but does not want to take OC on some cards (notably GPUs from #5 to #8).

Hi @Denrau !
Yes, I solved it!

But my problem (at GPU #2) was at GPU, I had change the GPU to other new.

For OC, do you tried to change bios? I did biosmod and could increase the performance considerably, and it made possible a good OC settings.

[Denrau]

So you took out GPUs one by one until it stopped hanging up?

[cirooc]

Yes, one by one until discovery the problem.
Did you tried do a biosmod?

[Denrau]

I did try to remove 4 out of 8 GPUs and changed every single part/wire/etc besides CPU and mobo. I’m getting to the point where I think I would have to try another board and CPU.
I have RX6600 and I don’t think there is a way to mod them.

I remember that I deactivated some functions at MoBo bios, one of than was the audio port.

Did you tried it too?

[Denrau]

I don’t have one on the mobo. I’ll keep trying
