Just built my first AMD system in over a decade.

After installing and updating everything, I noticed the computer takes about 45 seconds to reach the motherboard logo screen after turning it back on or restarting.

A little research shows this is normal behavior for AM5 systems.

Is this true?
 
I did had a lot of those, there is DDR-5 training and other reasons but also issue, is your Am5 board an MSI as well ?, very common for them it seem.

Does having expo-XMP completely off, default 4800mhz ram setting no overclock change the reach the logo screen boot time by more than half ? If so you can look at some of the option that let the motherboard use the previous ram saved setting and other fast boot type option, you can look if a more recent bios adress some of the issue as well.

Yup, using an MSI B650M Project Zero

Unfortunately, running RAM at stock with no expo doesn't seem to improve the amount of time it takes to boot.

I tried looking for the setting to avoid memory training every time it turns on, but can't seem to locate it in my specific bios.
 
BIOS setting often tend to be all named differently from brand to brand, on that one it could be called Memory Context Restore that can be set to enabled:

There was many bios revision :
https://www.msi.com/Motherboard/B650M-PROJECT-ZERO/support

To some the AGESA ComboPI 1.1.0.2b did fix the memory retraining every boot issues, but that tend to be a case by case you need to try to see if it work for your specific board, a new build is a good time to update the bios (as if there any issue it hurt less to restart everything from scratch and the return policy tend to be easier)
 
Depends on a few factors. Assuming the BIOS is up to date, verify Memory Context Restore is enabled. (If it isn't, you'll want to do that) Where this is located is going to be different for every board. Memory training is something you'll hear about a lot but often misunderstood. A long boot does not mean its memory training unless the debug LED or POST code readout confirms as much.

B650 boards in my experience are just as quick as everything before it and my B550 system is 12 seconds from button push to login screen from off). However, my X670E system is roughly 30 seconds for the same thing but when it was new back in 2022, that was closer to 60 seconds.

Just a theory given there is a second chipset on board to initialize but its just a theory.

You want Memory Context Restore and Power Down enabled. PD is in the advanced memory timings menu at the bottom. If you're under 30 seconds or so, I would call it a win. My ASRock B650 was like 4 seconds to desktop, my current Gigabyte takes about 15-20 seconds. Not like it was at launch taking minutes in some cases.
 
Yes its normal due to memory training on bootup.

You can enable Memory Context restore and it will speed it up.

However I leave it disabled as I use XMP and conservative (my own less aggressive higher numbers based on Buildzoids ones so not full blast with Buildzoid but use them as guideline) Buildzoid Ryzen 7000 timings for M Die at 6000 and I want great stability so I want it to train every time thoroughly and am ok with longer bootup. Its not that bad really.

Would rather have platinum stability and a bit longer no video POST for 30 seconds than a fast POST and possible stability issues.

Not a bad idea once the initial setup is over and you do not reboot that often, the issue (for many, not everyone) will look worst at first because you reboot very often the first few days, but once you get into the sleep-wake up, reboot on some update or powerloss.... groove

Yeah, I've had my AM5 system since the first week they were available and TBH, I don't even think about it anymore. I rarely fully reboot at this point and TBH 30 second or so isn't the end of the world.

Some of the AM5 OG's will remember Sleep mode being completely disabled on all AM5 systems across the board for the first couple of weeks, that really compounded the concern. Luckily today it works just fine which is what I do when i'm away now.

That's interesting because I just switched to an MSI board and noticed that the boot time was longer than expected coming from a Gigabyte board. I didn't realize they had an issue. I'll have to try that memory context restore setting.
 
It’s never been a brand thing, but a specific board and configuration thing.
 
Used to have a MSI MAG B650M Mortar and it had a long boot, before I updated the BIOS it would take an agonising 2 minutes just to POST, updating to the latest BIOS would take more than 30 seconds which is an improvement but not great. Disabling XMP/EXPO would further decrease the boot time.

Now I have a Gigabyte B650M Aorus Elite AX motherboard and it would take at least 15 seconds to POST with XMP/EXPO, from what I read MSI and ASUS AM5 boards take a while to POST.

That's funny because I went the opposite way. I had the Gigabyte mATX and moved to the mortar. The MSI board definitely takes longer to boot but I will have to play around with that setting linked earlier
 
I eat the longer POST time to have a faster and more stable system. Power down mode should be disabled on a desktop, and you can't run this with MCR on.

My new computer boots to Windows 11 login screen were 64 seconds repeatedly with no change to BIOS.

I changed some BIOS settings:
1) I changed my profile to boot at 6400mhz DDR5 which is the speed of my DDR5 (original mhz was set at 6000)
2) [ENABLED] memory context restore

other:
Disabling onboard graphic did not change anything. I'm still trying to see if I can tune it for better results. My previous build from MANY years ago would start faster when it was fresh. I have noticed though, the more drives I have plugged in anywhere to the motherboard in the past with lots of information on them would make the boot time longer. Currently, I have two m.2 drives connected, but plan to hook up 3 or 4 additional SSD's as I test through this. I feel like using a m.2 drive with 7,450 read speed can perform faster than 23 seconds. This is the drive controlling the load read speed and it's blowing mind BLAZING fast compared to anything we had 10-15 years ago. Let's find the bottlenecks!!!

I boot to Windows 11 login screen in 23.9 seconds every time now from push on.

Ryzen 7 7700x
MSI MAG B650 Tomahawk
m.2 990PRO 2TB 7,450 read/write
6400mhz DDR5

For me i'm convinced its the initialization process of X670, at least with my board. I truly feel B650 handles this better. Since new in October 2022 till today, i've shaved about 30 seconds off my button press to login screen time. 60 seconds to roughly 30 seconds.

15 BIOS updates, the addition of MCR and realizing that having a USB-C display connected to the USB4 controller on the board stalled booting for 10 seconds. I'm, at this point, not sure it is going to get any faster.

Meanwhile my B550 system is like.. 12 seconds?
 
Yes but B550 is DDR4. Long ass boot time was introduced with DDR5 and memory training.
It's not AM5 specific as I had the same crap on Intel DDR5 build I had previously.
Apparently you can get fast boot time once memory is trained, but I never got to that point even after a year and a half of owning my old Intel DDR5 system. Whoever came with that idea should've been fired.
 
Just switched back to AMD after roughly twenty years. A lot of good information in this thread.

I'm well aware, I've had this B550 system on my desk since launch along with this X670E system since launch. I've been through the gauntlet of week one launch BIOSes to current day with both.

With X670/B650, ensure MCE is enabled and that will prevent memory from training at every boot. However, depending on how long the rest of the boot process takes, it may still be longer.

My X670E system does not train memory at every boot (I have a 7-segment display to see what's happening) but button press to login screen is still 30-32 seconds. Everyone I've spoken to with B650 says this is not the case, that boot times when memory isn't trained are 12-15 seconds, however most X670 systems its closer to what I'm seeing.

I'm convinced there is just something about having the second chipset that lengthens boot times. That or extra devices like the Thunderbolt/USB4 controller.

X670 is simply two of the same chipsets you get on B650. I've used several X670 and B650 boards and the boot time varies but generally under 10 seconds (nowadays, not at the launch lol). The fastest I've used was the ASRock B650M-HDV/m2 which with hybrid sleep off took less than 5 seconds to desktop. The slowest was an Asus B650-A which took 30-45 seconds no matter what. I just recently had an MSI X670E board here and that one was very quick too.

But we argue about this, and forget just a few years ago a non-TPM windows 7 machine could be at the desktop almost before you let your finger off the power button. I just trotted out my 4770S system for a project I'm doing and it hits the desktop in Windows 7 in under 2 seconds.

Again, I'm well aware of what this platform is. In the past year and half of ownership, participating in many discussions across various platform I've never heard of 10 second boots with X670 specifically. B650 sure.

You’ve used one board, I’ve used probably 40 of them since the platform launched. If we want to compare anecdotal evidence then I have plenty.
 
I will say I just upgraded to the 7800X3D from an Intel 14700K and the boot times are about the same. I didn't even have to do a fresh install of windows which I was set to do, but things are working great so far. Installed new hardware and set the recommended settings pulled from this thread with XMP enabled and the system boots very quickly.

How exactly is that an upgrade?

Well seeing as I don't have to worry about any odd occurrences with the 14700K I consider it an upgrade. I know performance wise it isn't much but I feel it is to me anyway with less anxiety on my part.
