New Stepping Intel 9th Gen CPUs Now Supported
ASRock is rolling out BIOS updates for their 300-series motherboard line in preparation for new Intel CPUs. This is not only for their high-end Z390 line, but other 300-series chipset boards as well. Including B360, H310 and H370 chipset motherboards.
These are still 9th Gen Intel processors. However, these are new stepping CPUs with a R0 id, instead of the P0 from existing 9th Gen CPUs. What these differences mean is not yet known for Intel, nor motherboard makers have disclosed it.
A stepping change can mean many different things. It could have minor fixes, or even enable higher clocks.
