Topic: Trouble setting up RX 470 rig with simplemining OS and Hive OS - error 0xc000022 (Read 179 times)

Hey. Sorry to hear about your temp and crashing issues..
It does sound hardware related and not software though. I would suggest to strip it right back. I personally use PiMP OS, but that shouldn't matter for this testing.
Try booting it with just 1 gpu (not the 35w one) and 1 psu connected.
Try making sure you have either the standard Rom, or only PBE One-Click mod ONLY.
As rikuu said, ditch the undervolting for now. Tune later.
Try a little more conservative setting, maybe 1025 and 1900? I have some 4gb rx470's (Hynix mem), running only PBE1C, 1025, 2025, NO UNDERVOLT, and getting 28.2mh/s@52w on ETH.
If you try the above.. run it for a day or 2 to see temps and stability.. then add a card. Slowly slowly.. you'll get to the bottom of it.
When you do find the issue and your rig's running stable.. then you play a little with undervolting to maximise your return.
Best of luck.. happy mining!

Do you get these errors when you don't OC and undervolting them?

is the heat spike always hapening on the same card?

Regarding not being able to connect more than 4 GPUs, is the BIOS option "encode above 4G" enabled?

How do you set the voltage on the GPUs?

I have a rig with Prime z270-a motherboard

I'm putting RX 470 cards on it, but having trouble.

For the overclocking in Simplemining OS, I set Core MHz to 1050, Memory MHz to 1950 and Core undervolt to 900.  Powerstage is set at 6 and minimum fan speed is 70%.

I'm also using two separate power supplies that are linked together. The  1000 watt PSU is running five cards, and a 450 W PSU is operating two cards.

When I try just one card with no other cards in a single PCI-E slot, it will drop the wattage to 35W and the heat will spike to 85°C.

I had card number one in PCI slot number one and it worked for 24 hours just fine. I try hooking up the first two cards and one of them will drop to 35 W and give me the heat spike.

I just hooked up cards 2, 3 and four and had been working fine. I tried number five and received a message saying that my keyboard was not detected and it wouldn't work. I pulled card 5 off and now I'm getting an error 0xc0000225. 2, 3 and 4 cards were working and now it is giving me an error. If I pull the cards off, it goes back to my screen to go to the bios.

Just to note: I received this error before when I tried another motherboard. I was also using an SSD drive and was using Hive OS. I switched to  another motherboard and a USB and Simplemining OS, but just received this error and having the same issues where wattage drops and the heat spikes.

I have also tried just running the 1000 W PSU by itself.

I don't know what to do. If anyone has suggestions I would appreciate it.
