Hey, my max memory speed is only 1075mhz. I know that that my gpu the 6800xt can be tuned to a higher speed. Because i used Amd adrenalin on windows in the past. How can I increase my max memory mhz? I use fedora as my os.
And about the voltage in CoreCTRL its differently displayed. How big does the -number need to be to get to 1060mv?

afaik linux and windows shows different GPU memory clock speeds but it's basically the same (1:2 conversion)
most likely because bigger number = better?
my AMD 6000 cards does the same

I think i found the answer. Windows counts the total speed including the effective bandwidth, while most Linux utilities only report the raw clock speed.

I overclocked my RX580 recently. Here is how to do it in CoreCTRL.

Currently, to have full control of your AMD GPU while using the amdgpu driver, you need to append the boot parameter amdgpu.ppfeaturemask=0xffffffff to your bootloader configuration and reboot. NOTE: The following instructions are for guidance only. Check your distribution documentation on how to add boot parameters.
GRUB bootloader Edit the file /etc/default/grub as root and append amdgpu.ppfeaturemask=0xffffffff to GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_CMDLINE_LINUX_DEFAULT="... amdgpu.ppfeaturemask=0xffffffff"
NOTE: In the above example, ... represent other existing parameters. Do not add ... to your GRUB_CMDLINE_LINUX_DEFAULT. You should only add amdgpu.ppfeaturemask=0xffffffff. Then regenerate the bootloader configuration file with the command:
sudo grub-mkconfig -o /boot/grub/grub.cfg
Reboot your system. You should have more controls when you select Advanced as Performance mode where you can tweak the mhz and voltage easily.

I did this and i can tweak the voltage and stuff. Just max memory is wrong. On amd adrenalin i was running vram 2124mhz and here only 1075mhz. And how does the voltage work in CoreCTRL i only know how to do it in amd app in mv but i dont know what -30 is.

In CoreCTRL, you tweak the voltage for each state. -30 in your case would reduce the voltage by 30 mv in every state which is not ideal. Just deduct 30 mv in each state in CoreCTRL.

Chances are the answer lies in your firmware
