Hi,

Currently my bios is 5.1 and I would like to update BIOS to latest 1004B. but your website said: ASRock do NOT recommend updating this BIOS if Pinnacle, Raven, Summit or Bristol Ridge CPU is being used on your system.
So it means I cannot update BIOS or what? I am using 1700X CPU and hope to try other BIOS version.

Dear Etigil,

Greetings, this is ASRock TSD.


We do not recommend users to update the BIOS if the system is already running normally.

However, if you would like to update to BIOS P6.40, please update to P5.50 first and then update to P6.40 via instant flash method.

Thanks!

All the best,
ASRock TSD
