Hi VG1, Thank you for your post. Z490M-ITX/ac and H470M-ITX/ac support Intel 10 Gen CPU only. And the BIOS which supports C.A.M (Resizable BAR) has already uploaded to the website. Please download the BIOS from the below link. Z490M-ITX/ac L1.32: https://download.asrock.com/BIOS/1200/Z490M-ITXac%28L1.32%29ROM.zip" rel="nofollow - https://download.asrock.com/BIOS/1200/Z490M-ITXac(L1.32)ROM.zip H470M-ITX/ac L1.22: https://download.asrock.com/BIOS/1200/H470M-ITXac%28L1.22%29ROM.zip" rel="nofollow - https://download.asrock.com/BIOS/1200/H470M-ITXac(L1.22)ROM.zip After updating BIOS, please follow the instructions below to enable "CAM". 1. boot into BIOS and go to the "boot" page, then go to "CSM" 2. Disabled "CSM" 3. Go to Advanced\chipset configuration, then enable "Above 4G decoding" and "CAM" Please make sure you are using the AMD RX6000 series or the NVIDIA 30 series with the vBIOS which supports Resizable BAR. I linked the instant flash SOP as below. https://www.asrock.com/support/BIOSIG.asp%3ccat=BIOS9" rel="nofollow - https://www.asrock.com/support/BIOSIG.asp?cat=BIOS9 If you have other questions, please feel free to contact us.

Why? Intel has recently announced that its new Z490 and H470 motherboards for the 10th-gen lineup will also support the Rocket Lake CPUs. Only H410 and B460 doesn't support. Why Z490 Phantom Gaming-ITX/TB3 have bios update then? 1.32 and 1.22 are BETA bios. What about stable final version? |

It's the reason https://www.guru3d.com/news-story/likely-not-all-z490-motherboard-will-support-rocket-lake-s-processors.html" rel="nofollow - https://www.guru3d.com/news-story/likely-not-all-z490-motherboard-will-support-rocket-lake-s-processors.html the sad thing is some motherboards like GB B460M DS3H V2 is compatible with rocketlake. Its was my first and last motherboard from Asrock. :( You should be ashamed. |

Same thing. Even Resizable BAR is not finished, only beta. |
