1  Alternate cryptocurrencies / Mining (Altcoins) / Re: - Modded RX 580 BIOS - Can't overclock/underclock!!! on: January 30, 2021, 10:26:26 AM
I'm glad to let you know that I finaly manage to fix it few hours ago, even If I dont really know how I did that...
I've made a bunch of cleanup, reinstalled/uninstalled stuff which might have been badly uninstalled by the past like Afterburner, Gaming App, Control Center, etc...
It finalement worked with old 18.5.1 Adrenalin and now with latest drivers, I'm ocing/ucing with OverdriveNtool.
I guess there might have been somewhere an old config' file or script of an unidentified software that locked everything else.

The only odd thing is that I cannot set target temp. below what bios says and GPU fans can't go below 30% , but I can oc/un any other value and mining ops look stable.
Thanks anyway for your support Smiley

This would let you make sure its not the OS giving you fits and if it does mine on linux..then its at least you know its not your hardware. 

At most would just require a reboot to switch.



You are right, I'll look after a HiveOS tutorial and give it a try.
Even if I can apply oc/uc changes under Beta Blockchain drivers.

My board is full of 570 and 580s.  Only the one top pci do I put the card directly on the board.  The rest I use risers powered by a 1200w power supply. I do that so I have video to my monitor.  
I would suggest you not over clock so high.  Bring them down and see if it gets better.  I had the latest bios as well. Think my settings are 1200 and 2150 roughly. Undervolted differently per card. All modded. Using blockchain drivers.
Because I’m running Polaris I’m using 5.1c.   Not sure what else to tell you.  Mine runs a month at a time with no problems.  Maybe try to find the problem. Is the 5700xt modded? Mine are modded
On my asrock board I use 2 5700xt and they would shut down several times a day.  Found the problem was I was using 1330 for clock.(I think of hand)  I backed it down 20 or so and been smooth sailing.
Because you are only running 8 fb ram maybe try adding virtual memory as well.
Are the risers new?

Use newer driver and newer miner version. Blockchain driver is very outdated and not needed.

Does anybody got 6 GPUs on Rog Strix B540-F ? (I mean without using M2-> PCIe converter). Thanks !

Yes, why not? There is nothing special on this mobo

Hi sxemini.

I'm facing an issue with oc/uc my modded RX580's , which I can do only with Beta Blockchain drivers. Thread opened here: https://bitcointalk.org/index.php?topic=5312692.0
With any other driver, oc/uc values are set back to bios stock values as it was forgiven to modify them.
Any idea?

I might give it a try... I use windows to be able to easily and quickly switch between mining and doing other tasks.

Try going back to stock bios and see if oc/uv allows any change.
If it does then need a different bios mod.



After a few tries once more, nothing wroks, even with stock Bios.

The only driver still allowing oc/uc is Beta Blockchain.

I have no clue about what to do to fix that, except formatting and reinstalling Windows and drivers, but would really want to avoid that.

I wonder if I might mod bios to include voltage and memories I found working best for each GPU... Would that be stable?

Hi friends

I hope mining and everything else go fine for you.

Back to mining (casual mining this time), I'm facing a problem about tweaking values.

I managed to flash bioses of my two RX580 Gaming X 8Go's with Ubermix 3.1.1 and Hynix agressive stance (Samsung/Hynix memory).
It works fine, but I cannot overclock/underclock with software like OverdriveNTool, Afterburner, or even Radeon software itself! As soon as I apply value change with software it resets back to bios values and accept changes under no circumstances.

I'm running under Win 10 Pro.
I've tried many AMD drivers, the only one which allows me to change values is the old Crimsom Beta Blockchain driver.

But for various reasons, I'd like to use latest AMDdrivers.

Any idea about what I may do wrong or what I could do to fix it?

Thanks anyway for your help! Smiley
