After recently introducing the AMD AGESA 1.0.0.4 BIOS firmware, MSI & ASRock have removed the download links after discovering a major issue that affects Ryzen 7000 CPUs.<\/p>\n
Earlier this week, we reported that MSI was amongst the first motherboard maker to offer support for AMD’s AGESA 1.0.0.4 BIOS Firmware on its X670 & B650 motherboards. However, after making the download links to the new BIOS go live, motherboard makers such as MSI & ASRock have now removed them due to a major bug that AMD has discovered.<\/p>\n
\nMSI & ASRock removed X670\/B650 AGESA 1.0.0.4 (SMU 84.79.204) BIOS from the websites.
It’s rumored some 7600X are downcore from 2-CCD SKU with Core0 disabled, with which 1.0.0.4 can’t boot. AGESA 1003 is fine.
New SMU 84.79.210 will fix. 1.0.0.4 BIOS still on Gigabyte website. pic.twitter.com\/N8wnryyXgg<\/a><\/p>\n\u2014 chi11eddog (@g01d3nm4ng0) January 7, 2023<\/a><\/p>\n<\/blockquote>\n
Based on the information from our sources and also the reputed leaker, chi11eddog<\/a>, it looks like the issue with the AMD AGESA 1.0.0.4 BIOS firmware is that it fails to recognize the CCD & makes one core entirely disabled. In the case of the Ryzen 5 7600X CPU, the new AGESA firmware locks out the Core0 from being used. Now this problem has been reported in a few cases and that’s due to the fact that the BIOS is very recent and not a lot of people have updated it. However, MSI and ASRock reacted fast to the discoveries made by AMD and have removed download links to the BIOS firmware for their motherboards.<\/p>\n
