ASRock X670 may need some time to load
According to the photo posted by hardware leaker HXL, ASRock’s new X670E motherboard will take 100s to 400s for first boot.
The sticker attached memory section ensures the correct installation of DDR5 modules. This chart also has information how to install one, two, or four memory DDR5 modules. More importantly, it lists required time for first boot for each configuration.
For dual 16GB config it will take 100s, for two 32GB modules the time doubles to 200s. Same time will be needed for quad 16GB modules, and even more, 400s will be required for four 32GB DDR5 kit.
Although it is not explained, the time difference is likely because the motherboard will perform internal tests to find compatible and stable settings. It is also worth noting that 32GB DDR5 memory is usually dual-rank, which might explain extra tests for optimizations.
Yesterday, AMD’s Robert Hallock explained that the best memory configuration for the Ryzen 7000 platform is dual DDR5-6000 kit. The time difference for ASRock’s first boot does not appear to be correlated with the speed of the kit, but rather single/dual-rank and how many modules per channel are installed.
Still, 400s is still a very long time (6.6 minutes) which might be confusing to some users. So hopefully, it will be explained properly in the manual.
