The fact that the board is mis-labelled as DH61BR will not affect BIOS update operations or anything else that you do with this board. What sort of issue are you having with BIOS update?
Also, be aware that there are known compatibility issues with the use of modern graphics cards in older motherboards. Something that helps is to ensure that UEFI is enabled in the BIOS.
Hope this helps,
Scot, o chipset B75 não está instalado nessa placa-mãe, que é H61.
Obs.: comprei o modelo DB75ENBR, porém está sendo identificado como DH61BR.
Forget that; it's just a bad labelling job. Answer the questions:
- What sort of issue were you having with the BIOS update process?
- What is happening (or isn't happening) if you attempt to power on with the GTX 1050 board installed?
