The BIOS update could be connected to this situation (I noticed certain PCIe support removed to accommodate other components), but I experienced similar problems with my 5900X and a 3600X test bed because of RAM stability problems. The Ballistix I initially used wasn’t QVL'd for either board, and both faced issues—some alike, some quite different. My 5900X would freeze in sleep mode, showing random no video starts, crashes, and shutdowns. The 3600X build seemed to run improperly, displaying a persistent hourglass in Windows. The key clue came when I swapped the second DIMM in the test bed; the issue reappeared. I replaced it with aftermarket kits matching the same timings and voltage, and both functioned perfectly. It seems another previous machine had the same problem with different DIMMs that weren’t QVL'd, causing speed discrepancies. The machine has been acting erratically for about two years now, which likely contributed to this. QVL works better on Ryzen boards, even though some claim "RAM is RAM." Just be prepared for more Windows 11 complications after fixing this. Edited October 28, 2022 by An0maly_76 Updated with additional details
Great question! The Corsair cmw16gx4 and the new cmh16gx4 should work together without issues if they share the same frequency and are placed on the same VLAN.
This suggests the graphics card isn't the issue. Would it function without the new RAM? The BIOS update seems questionable—can we restore it or boot from the backup version if available? If not, removing the RAM and graphics card might help. There should be a method to reset the BIOS using a jumper; otherwise, you may need to discharge the battery before resetting.
