Nothing works, I am losing my mind over here

Thanks for the reply.

I am using Corsair HX1200 platinum and Win 10. I can see all of the cards in device manager and in GPU Z as well.

Problem is that neither GPU Z or Sapphire Trixx is reading current clocks. Afterburner (latest beta) is reading current clocks but if I change anything (fan speed or clocks), clocks fall to 300mhz and nothing but restart can get them up again.

It happens regardless how many cards are hooked up, I've tried with one in main slot and with 4 of them. I am waiting for molex adapters to connect all 6 of them together.

I'll try once again with stable drivers but as it didn't work, I've tried beta blockchain drivers and it still doesn't work.

On boards graphics is disabled and Intel driver is uninstalled using DDU.

Should I reinstall Windows?

Thanks for the help guys, I've tried plugging in monitor to each of them but it doesn't help.

Clock drops down to 300mhz even if I only adjust fan speed manually. Something is utterly broken here and I can't figure out what.

last bump, I promise

My post fell down, just bumping cause I desperately need help 

Hi guys,

this is my first post on this forum and hopefully it will be first of many.

I'd like to thank you for this amazing forum, tons of useful info here.

I am in the process of setting up my first rig, got all the hardware and assembled my open air case.

I am running Win10 with 6 AMD RX570 4gb (2x Gigabyte - Hynix, 2x Gigabyte Aorus - Hynix, 2x MSI Armor OC - Elpida) amd what do you know, I have encountered some problems. I'll number my questions so that it would be easier to respond. MBO is Gigabyte H110-D3A.

I am running beta AMD drivers but the following problems concur on latest stable Crimson drivers (17.7.2) as well.

1. I didn't put all of the cards in yet, because I wanted to flash modded BIOS and tweak them with only one of them in there. Problem is that when I plug each of them into my x16 port, GPU-Z doesn't read Pixel fillrate, Texture fillrate, Bandwidth, GPU clock or Memory clock. Screenshot is below. MSI afterburner does read current clocks but if I change any of them, they fall to 300mhz and card mines around 4 mhs ETH. Maybe I should adjust something in MBO bios? I have tried reinstalling (with DDU cleanup) the drivers many times but it doesn't help.



2. Flashing GPU bios - when I dump current MSI bios its size is 512kb. Ones I can find online are 256kb. I guess it won't work so could you please point me to good straps to use and manually edit all my gpus with Polaris.

3. I am using Claymore and out of the box I am getting aroun 21-22 mhs per card (ETH). I guess it should be higher when I manage to over/under clock them. When I try to dual mine ETH+SIA, my hash on ETH drops to around 16 mhs. I am reading that it shouldn't happen, what could be the issue? Below is my start.bat.


I guess thats it for now, but I have a feeling that many more questions are coming.

Thanks a lot in advance.
