AM5 Slow Boot times

[weyland yutani]

Since building a new AM5 system couple of months ago (7600X, Gigabyte B650 AORUS ELITE AX, 32GB DDR5, WD NVMe 1TB) the boot times have been incredibly slow, much slower than even my previous intel 2500K build.

On every cold boot up, the system performs a memory training cycle (RAM diagnostic leds are on) meaning I don't even see the motherboard splash screen for about 35 seconds. This is with the ram's Expo profile applied which sets the speed to 6000MHz CL38. There is a setting in the bios (Memory Context Restore) which help alleviate this but it causes instability, app crashes and even the odd bsod in windows.

It seems this is fairly common based on google searches but I was wondering if people here are experiencing it. I'm still on the original bios but dont want to update bios at the moment if it wont help this issue. Is there hope that future bios development will fix it?

Slow boot up only occurs every 10-14 days with the memory set to default speeds but every time when Expo profile is applied. I do have two HDDs in the system, will try without them.

Enabling "Memory Context Restore" in bios does speed things up but its not worth it for the system instability.

I'l put up with it for now and try future bios versions.

That's my drive too My ram is TeamGroup Vulcan EXPO 32GB (2X16GB) DDR5 PC5-48000C38 6000MHz

From the moment I hit the power button to seeing windows desktop is about 58 seconds (about 35 seconds no video signal before the mobo Aorus logo appears)

I do have windows fast start up disabled though, it always causes error reports of incorrect shutdown, even on other systems I have.

Just turned on my pc now and it felt like even longer than usual to reach windows. I should have done more research before my upgrade. If I had known this was an issue with amd I'd have gone intel

 

[weyland yutani]

Yes in my case. With memory at default it still happens but much less often

Intel isn't much better. Or certainly in my case running a 13900ks and apex board.

What does your "Last Bios time" state in task manager?

In task manager it states about 34 seconds on a slow boot up. Actual time from power on to desktop is more like a minute though. At default memory speeds it states around 12-15 seconds, which still seems slow to be honest.

I just took the plunge and updated my motherboard bios My motherboard is the Gigabyte B650 AORUS ELITE AX. I was on the original F1 bios, now updated to F4b (released on the 21/02/23)

Boot times are much better now with EXPO enabled. I've only done two or three boot ups so far so the memory training may reappear at some point but there's definitely a marked improvement overall.
