very long BIOS / BOOT time on new pc
very long BIOS / BOOT time on new pc
Hello, your concern relates to a not fully mature BIOS setup. It appears EXPO activation triggers RAM training during each boot, and enabling the memory context restore option causes instability. You can find more details in this AMD forum discussion: https://community.amd.com/t5/processors/...d-p/554174
Ensure the latest BIOS/UEFI is installed. Verify your RAM is included in the motherboard's QVL or the motherboard is part of the RAM's QVL. Activate memory training during the first boot after any RAM changes, and turn it off on subsequent boots. Sub timing could affect automatic EXPO by the motherboard. For Samsung memory, their timing patterns (e.g., 36-36-36-76) may indicate incompatibility; consider adjusting voltage slightly or returning the RAM for better compatibility. Opt for non-Samsung options, especially with new DDR5 chips.
The motherboard is included in the RAM QVL, but the chips are Samsung-made and function properly if you don’t skip the setup routine each time. I saw my BIOS reset when unplugged, which could mean a dead battery on a brand-new board. I’m returning both the RAM and motherboard, planning to look for another pairing.
On my second motherboard, encountering all the problems in this discussion means it’s likely to revert to Intel.
Updated to BIOS version 1004 on 30 Mar 2023. Managed to start with all four memory modules in BIOS ver. 0805 (third release from 15 Nov 2022). System functioned but was sluggish. RAM didn't utilize any XMP settings without becoming unstable, so I didn't achieve the intended speed. No "EXPO" profiles available; only XMP as "DOCP" or similar. ASUS UEFI BIOS offers AI Tweaker in Auto mode, a DOCP profile, or manual settings, which is why I'm sticking with auto mode for stability. Still experiencing boot problems. Each stick tested independently on memtest86+ showed no errors. RAM is within specifications. Supports 128GB, but requires removing two or more sticks to start. Successfully reached POST twice with all four modules, though random crashes occurred post-reboot. Disabling power to mouse/keyboard during boot attempts didn't help. CMOS cleared without success (except after removing a stick). BIOS was downgraded to ver. 1003 (beta) and then reverted to 0805, but nothing changed. I haven't attempted a lower version yet, though it worked fine with four sticks only. Performance remains slow despite having the hardware. The investment feels wasted given the price—especially after missing the purchase deadline due to travel. Anyone facing similar challenges during AM5 testing or video production would appreciate advice?
