Followed all your BIOS configuration steps (primary GPU set to use PEG/x16 slot, PCI-E speed set to Gen2, CSM enabled for Other OS installation, unneeded devices disabled, etc.).
All GPUs are brand new AMD RX-570 and RX-580 (not modded), and risers are working.
I am using hive-flasher to deploy a large number of GPUs on Biostar TB250-BTC PRO motherboards (upgraded to latest BIOS version).
Here are the issues:
First of all, the instructions for FARM_HASH usage (on this forum) and hive-flasher (on the GitHub page) are inaccurate and inconsistent. You need to update your instructions on both pages for consistency. From trial and error, I discovered that one must fill out BOTH the ārig-config-example.txtā and ārig.confā files providing the FARM_HASH and password. hive-flasher will not let you proceed unless FARM_HASH and password are filled out in rig-config-example.txt, and HIVE will not properly add the rig to the web dashboard without the rig.conf file.
Second issue: Unable to install the image when motherboard is set to use PEG/x16 slot for monitor. It tries to boot into the USB and always ends up with a frozen screen with white noise (but will install fine if motherboard is set to iGFX or PCI). Here is a photo:
Third issueā¦ As another user already said before: The rig does not always boot into GUI with more than 6 GPUs connected (if itās 8, 10, or 12 GPUs) - the rig will not boot into GUI or connected monitor. Another user has posted a photo of this issue, and it looks like this (black screen with blinking cursor):
Fourth and final issue! ALL of the GPUs report the following error: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff
Can anyone please educate me on what might be going wrong? My biggest concerns are the third issueā¦ where the rig does not boot into the GUI (or connected monitor) with more than 6 GPUs, and the fourth issue (Invalid PCI ROM header signature error).
I would appreciate prompt help, seeing as I am setting up a large scale mining facility and I have a deadline to finish everything. If I do not receive adequate help, I will have no option but to move to SMOS or minerstat.
I have same motherboard with 8gpu and no problem. PCI-E speed set to auto.
Black screen suggest that you may have one riser badly in socket. Start with half of GPUās and if work ad more , one at time.
In main PCI-E installed GPU may need dummy if started without monitor.
You can install image in another PC and when ready connect ssd to miner.
Fourth problem is not problem, i have same.
Iām using hive-flasher like I mentioned earlierā¦ to write to SSD. Apparently it matters what the Primary Display is set to in BIOS.
Also, like I said - PEG (x16 slot) does not work for the setup. I tried with Auto and Gen2ā¦ and I get the same result. Only iGFX and PCI work.
Edit: Iām thinking nowā¦ that the reason PEG doesnāt work, is because an x1 riser adapter is connected to it, as opposed to a full length x16 card (which I cannot connect due to space limitations)
There are no loose risers. I have triple checked them all. All 12 GPUs show in POST.
The black screen with blinking cursor is apparently the GUI switching from āinternal to external GPUāā¦ (according to someone else on this forum). I tried switching the HDMI cable to all 12 GPUs, one by one, after the screen went black with a blinking cursor, and I still did not get anything on my monitor. I tried this a few times, because it always happens to me with 12 GPUs connected. It works with less than 8 GPU, but with 12 - always goes to the black screen with the cursor.
I cant remember exactly witch one i set to primary, but it wasnāt internal graphic cos miner didnāt like it. I can check exact bios settings at weekend.
Disable any hibernation and sleep modes too
I have this setting.
This time as soon it starts mining, screen goes black and cursor stays top-left coner. This is probably because hive2 . I connected first time monitor to rig with hive 2.
No luck for me. The latest version, 0.5-72, is sending my rigs into a constant reboot loop: Boots, connects, and then reboots. And keeps looping indefinitely.
Lack of developer support on this forum has practically shown to me that I cannot rely on this platform, and I think that my money will be better spent elsewhere.
Sorry guys, but Iām not able to make any sense of your buggy software. Time to look for something more reliable.
Did you disable internal graphics too?
I look at pictures and i have PEX16_1 made as root.
Have you tryed booting from ssd or hdd? I had problems with USB so changed to ssd
And like I said, the latest version of HIVE (0.5-72) sends the entire rig into an endless boot loop.
Older version (0.5-57) did not have the boot looping issue, but had a very difficult time installing on a fresh 12 GPU build no matter what the BIOS settings were. I described all the issues in my initial post.
I found out the hard wayā¦ that running 12x MSI RX 580 GPUs was drawing too much power from the power supplies. The reason why the rigs would go into boot loops, is because the total power drawn from the power supplies was greater than was immediately available. I had specād the power supplies to provide enough juice to the GPUs, but with not too much overhead.
The solution was, to immediately go to the Overclocking tab of each new rig as it booted, and change the Core State Index value to:
ā1ā.
This would allow each rig to run without crashing and/or endlessly boot looping.
A value of ā1ā instructs the GPUs to reduce power in idle cores, while a value of ā7ā would increase power consumption drastically on all cores (5 is the default value).
So, in order to be able to work and configure each 12 GPU rig, I had to start each rig with as little power consumption as possible.
Advice on RX 570 and RX 580 overclocking would be greatly appreciated. I have just over 450 GPUs at this facility that Iām launching - mix of MSI 570/580.
Iād like to eventually get into BIOS modding, but right now Iām pressed for time and have a deadline to finish building everything. So for now, Iām just looking for safe and effective OC values (Core, Voltage, Mem, etc.)
Any recommendations? I found these GREAT values for the RX 580 (working like a charm at 30 MH/s even without BIOS modding):
But I didnāt see anything like that for the RX 570.
