In reply to Ciprian V.. It was a problem with Add2psu . Better to make a DIY short at second PSU. Now all is running ok. Thanks!

Hi guys!!
I have a problem mining with my RX570 (Sapphire Pulse ITX 4Gb) with a Biostar TB250-BTC. When I plug in (through a PCI Riser) at slot 1 I can reach a good hashrate (29,6Mhs). But when I plug in same PCI Riser and same VGA at slot 2, 3, 4, 5 and 6 I can’t reach similar hashrate (less than 22Mhs).
I can see, with HWinfo, that GPU CPU Power is always less than at slot 1. I have updated MoBO to last bios version, drivers AMD to actual version and all is ok in Device Manager in Windows 10.
All configuration in bios is correct for mining (mining mode, 4G, …).
Even I have done some tests in another identic motherboard with same results. I don’t know what can be the problem. Is it a factory fault? Any idea?

In reply to Ciprian V.. Would a Add2PSU adapter be necessary if power is supplied via these AUXPWR ports with PS1 and PS2, respectively?

In reply to hottovix. When you first start the bios setup, the question is whether you want to use as mining machine, if yes, choice between 6 GPU or >6GPU. I suppose you need to get back to that selection screen.

In reply to Norman Hirsch. Did you have to change any bios settings in order to use the 8 cards on one mobo? I have 6 running fine, but am about to install 2 more on this mobo.

In reply to Norman Hirsch. Thank you for your quick reply. Seems like you have had several problems with TB250-BTC+ but yet you keep going back to it. Have you tried other Mother Boards?

In reply to Karolis Taujanis. BTW, there is new bios. In any event, you need to set internal graphics as default and enabled and you'll see the screen from the motherboard video.
