Hello. I noticed some odd behavior that doesn’t quite match what others have seen on AM5.
With different RAM kits (2 so far) I’ve gotten indefinite hangs only on 2nd reboot when changing RAM speeds, either to the EXPO profile, or back down to default speeds. (Problem 1)
Additionally, EXPO II’s tight timings will also cause a boot and reboot indefinite hang. (Problem 2)
An example of Problem 1 is taking a kit up to EXPO I (one) speeds (6000MT on one kit, 5200MT on the other) or even back down to stock 4800MT. The system reboots and trains the memory fine, loading to Windows. Upon a 2nd reboot from Windows, the system will get stuck indefinitely, with the power button solidly lit, fans at POST default speed, and no display out. Manual press-and-hold the power button for 8 seconds will not clear this issue after several tries, however turning off the power supply for some seconds, waiting, pressing the case power button, waiting, and turning the power supply back on will solve the issue permanently. The system does not get stuck after this point, so far.
For Problem 2, EXPO II’s (two) tight subtimings on 5200MT/s make my mobo hang on boot and reboot, randomly. That particular issue was solved by going to EXPO I (one).
I understand how too tight of subtimings can cause things to get stuck for Problem 2. However for Problem 1, changing speeds whatsoever causes the system to get stuck, even going back down to stock speeds, after the initial training, during the 2nd reboot (not the first initial training period). So far I haven’t seen this behavior anywhere else online.
My motherboard is an ASUS Prime B650-PLUS on Bios 0823, with a 7700X. It’s not the best motherboard, but I bought it before reviews came out.
What do you think about these issues?
EDIT: Apparently they released an updated BIOS on the 24th, version 1222 with AGESA 1.0.0.5c one day after I last checked. Perhaps this will fix it, however I’m going to wait as there seems to be significant issues with 1222 on various ASUS boards.
