Can you find a method to reduce the boot time? The PC boots more slowly now compared to the 5800X3D I owned before. RAM is at 6000MHz on EXPO 1 profile. Are there any BIOS settings you can activate to speed it up?
Join the AM5 community! Make sure Memory Context Restore is turned on in BIOS to skip memory training during every startup.
Reasonable. Performance changes significantly, requiring more initial hardware setup, which is worse. The only AM5 system I’ve seen that starts quickly is my Asrock Deskmeet X600 paired with an R5 7600, booting in about 5 seconds. My home desktop does the same, roughly 15-20 seconds. Other AM5 setups are comparable but need more time to initialize. You might consider disabling unused devices in UEFi, though I’m uncertain about its impact. If you’re not using features like built-in sound or LAN, that could help speed things up.
I have an idea about this but haven't tested it yet. It seems simple B650 models run quicker than more complicated X670 ones. Just a guess. Recently, my boot times have noticeably improved since the AM5 era, after almost 15 BIOS updates, but it still doesn’t match my B550 setup.
Setting up dual south bridges similar to those on X670/X670e extends POST time, just like any other board part. Interestingly, the only chipset I haven’t purchased is B650e—though I’ve acquired three distinct B650 boards, including an X670 and an X670e.
Yeah, Ok, that's exactly what I've been assuming. I even had a wild discovery in which having a monitor hooked up to one of my USB4 Type C ports (which is wired to the iGPU) caused an even longer boot sequence. Unplugging that monitor and booting took nearly 10 seconds off the boot time.
Absolutely, you're aiming for a streamlined setup. Extra components on the motherboard should be handled during POST initialization, keeping things simple. I'll keep an eye on it later today if I remember—since I don't have the built-in NIC or sound card. There are occasional weird POST issues; sometimes my GPU fails to start and I don’t mind using a different 12V power supply just to get it working. It should happen consistently, though I might need to power down the system occasionally to see a display output. My old 4790k still boots quickly, except for this B650 Deskmeet build. It hasn’t got a dedicated GPU yet—those replacement M.2 drives are still pending—and I haven’t received them yet. I’ve been testing it on my Razer Blade 2016 using its original OEM NVMe M.2 drive.
Sure thing! Your rig responds pretty quickly—about 12 seconds from the power button to login. I’m curious how much faster it would be with the X870 or newer models. Honestly, I wasn’t sure about the X670, but I think the B650 wasn’t even available when Zen4 launched.
The X670 board is designed for a production server environment. For optimal performance, the developers suggest using a 13900k or 14900k processor. I tried it with a 7950x because they hadn't tested Ryzen before, and it functioned. A 13900k would have needed two server licenses and offered fewer ECC options. The benefit is noticeable—when I update the machine each month, it installs and restarts faster, around 20 times quicker than others, usually taking about 15 to 20 seconds.
