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.
MassCore users : Pyramix 10.1/ Ovation 6.1 or above required (RTX2014 SP2 Update 2).
The MassCore engine will not work with previous Pyramix or Ovation versions.

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


Validated BIOS version : 1.40 & 2.00    - 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!
Merging recommends you use Windows 10 with this motherboard.
If you rather want to install Windows 7, you must first create a compatible installation media, as Windows 7 does not include compatible drivers for this motherboard.

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.

Please follow the instructions from ASRock manual to install Windows 7 (USB driver issue)

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® Control Center.
Do not install the AppCharger, ASRock 3TB+ Unlocker Utility, ASRock A-Tuning utility, App Shop!
Norton Security is not mandatory at all, you may use another antivirus software, correctly configured.

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 or PCIe4x slot.
RTX64 dongle (SSK-HUD-RTX) users must install the specific HASP HL drive before installing MassCore.
Select the “Windows GUI” installer
Black Magic Decklink Studio/Decklink Studio 4K & AJA cards should be placed in PCIe slot 4.
Black Magic Mini-Monitor can be placed in PCIe1x or PCIe4x 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.

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.


If you don’t activate Windows, RTX64 will stop working after the Windows Activation period.
