First assemble the computer parts.
For ease of use during Windows installation, Merging recommends that you install security dongles, NET-MSC GBEX1, MT-USBSync board and Pyramix-Ovation keyboard after the Windows Installation.
Please make sure your Windows and Pyramix-Ovation-VCube versions are compatible, see this page for details.

Merging highly recommends you "defer feature updates" in Windows 10.


Validated BIOS version :
Z590 PRO4 : 1.50 / 1.60
Z590M PRO4 : 1.60
Please consult for other BIOS support.

First update BIOS if required. 

When updating the BIOS, all settings are lost or not set correctly, you have to enter all the parameters again manually.

Merging recommends you unplug all drives before updating BIOS.

Merging Technologies will not be hold responsible for any trouble or error during a BIOS update.

!Merging Technologies does not guarantee any issue or instability if any overclocking is enabled!

Sealevel GPIO 8206 & 8206FX are NOT compatible with this motherboard, because of their incompatibility with Intel USB chipsets.
Other SeaLevel GPIO are compatible, see our supported controllers table for details on supported models.

BIOS first opens in the EZ mode page, a summary of the system information.
You may adjust date and time.
Please switch to Advance Mode (F6)

1.3.3 Storage Configuration

SATA Controller: Enabled
SATA Mode Selection: AHCI / Intel RST Premium (RAID)

If you plan to use RAID array, you should install Windows with this setting set to Intel RST Premium (RAID), even if your system drive will not be in the RAID Array.
You will need to add the RAID driver on your installation media, download it from the manufacturer website or use the Easy RAID installer feature (see 1.4.3 below)
PMX V11/ Ovation V7 to PMX25th Hotfix2 / Ovation 9.0.5, MassCore users running a RAID configuration must use a dedicated RTX dongle (SSK-HUD-RTX) to authorize MassCore.
This issue only affects the system (Windows ) RAID drives, if you have RAID Data drives, a dedicated dongle is not required.
Since PMX25th Hotfix3 / Ovation 9.0.6, the RTX dongle SSK-HUD-RTX is no longer mandatory.

To configure your RAID array, please see the RAID Installation notes below.

1.8 Saving your BIOS/UEFI settings

You can save your BIOS settings in the OC Tweaker page, into the motherboard ROM or on a USB drive (must be formatted as FAT32)
After a BIOS update, those settings might be lost or incompatible with the updated BIOS version.

RAID Installation notes

Compared to previous generations motherboards, the system must now run in EFI. In this mode, the system is more prone to System Management Interrupts, that can cause audio drops. 
Therefore please be very cautious when installing third party programs.

  1. Go to Boot > CSM and set CSM to Disabled
  2. Go to Advanced > Storage Configuration and set SATA Mode Selection to Intel RST , then save the configuration changes and exit setup.
  3. Go to Advanced > Intel Rapid Storage Technology
  4. Create a RAID volume
    Set a name and select the RAID type you need
    Select the drives to be part of the RAID volume (select the drive, then select the X symbol)

  5. Select Create Volume and press Enter to start creating the RAID array.
  6. Save the configuration changes and exit setup.
  7. Boot the computer on your Windows installation media.
    Please note that you will need to provide the RAID driver (F6 Drivers) to install Windows, as those drivers are currently not included in the Windows installation.
    Those drivers can be downloaded from Asrock website, as the other motherboards drivers.


Windows 10 users may install from Windows 10 CD or USB bootable drive.


Merging recommends to download the latest drivers from

Merging recommends to install WHQL (Driver certified by Microsoft) .
Install the drivers ONLY, do not install the utilities it can cause much trouble.
Do not install Intel® Wireless Lan driver.
Do not install the ASRock Motherboard utility, Nahimic3 utility, APP Shop, ASRock Polychrome RGB ver:2.0.49

If you have installed a PCIe graphic card, you should now install its driver.
See the Graphic cards recommendations and Graphic cards recommended settings.

Now you can follow our Windows configuration guides 



After the installation plug Security dongles, NET-MSC-GBEX1 and other Merging hardware.
(not the Ovation-Pyramix Keyboard!)
See dedicated install guide / user manual for further details.
The NET-MSC-GBEX1 card can be fitted in PCIe1x.
RTX64 dongle (SSK-HUD-RTX) users : driver included in MassCore Runtime installation, please plug the dongle when installing MassCore.
Black Magic Decklink Studio/Decklink Studio 4K should be placed in PCIe slot 4.
Black Magic Mini-Monitor can be placed in any PCIe slot.
Black Magic driver has to be installed separately; it is not included in Merging installers.

4.1.1 Authorization Keys

Insert the authorization keys in MT Security Settings.

MassCore users can go now in MT Security MassCore tab and click on Install MassCore Runtime.
Restart the computer after MassCore installation.
Windows must be activated to be able to install MassCore.

See the MT Security Troubleshooting in case of issues.


Install Google Chrome
If there are several users on the computer, you need to use the alternate Chrome installer for all users :
Set as start page !

You may also install additional VST Plugins now.

If you have controllers, you can install the required software (Eucon, NetSmart, GPIO,....)
Networked controllers cannot use the same IP addresses range as the RAVENNA Network.
See this page for further details.
