Topic: Sapphire Pulse 580 8gb how to mod bios and OC - 12x GPU rig (Read 134 times)

Thank you so much mate.
I thought that win10 1079 version combined with the blockchain drivers recognizes up to 12 cards, doesn't it?

You can install Windows either using the onboard video or a single card connected to the PCI-E x16 slot through a riser.  You can flash/save the Bios of up to 10 cards connected in Windows using AtiFlash and Powershell. Connect 10 cards and save the orginal Bios by naming it according to the cards index in Powershell, so you know which card it belongs to. Then remove all the cards and connect the rest of the cards to save the Bios. You need to verify all the cards the have the exact same memory type and Bios with Polaris Bios Editor before you flash the Bios back to the card. If they all have the same Bios and memory type, you can flash the same Bios to all the cards after you do the Bios mod.

After you have all the cards Bios modded, run DDU in safe mode to remove the driver installed by Windows and disable the Windows automatic driver install, then select clean and shutdown to remove the drivers. To run more than 8 cards in Windows you need to use the latest AMD Adrenaline drivers. After shutdown connect all the x1 GPU risers to the motherboard and install the latest driver. Also enable the group policy to disable driver updates since you don't want Windows Update to update the drivers.

gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

Afterburner will not work with the latest drivers and multiple cards. Either use the Claymore config file to apply the overclock and undervolt settings at runtime, or use OverNdrive tool to create overclocking profiles for your cards as explained on www.mining.help.

Hi there. So, i've been reading some guides around and figured out something; still have some dubts.
What is the correct procedure to make it work the best way?
For what I learned, it should be (considering I'm starting the rig for the first time and that I've 12 cards with a H110 pro btc):
1)plug only 1 GPU to the 16x directly, install windows, no driver install.
2)make a backup with atiflashtool, restart the rig.
3)load a modded bios, restart the rig.
4)install latest blockchain computing drivers, restart the rig.
5)use afterburner or trixx to OC the GPU and to undervolt it.
6)add the cards 1by1, flashing, overclocking and undervolting them 1by1 (if they all have the same memory).

Anything wrong? Do I need to overclock and undervolt the cards with afterburner/trixx or the modded bios does it already?
And do I need to do the point 6. stuffs 1 gpu by 1?

Thank you so much!
