Question What causes slow BIOS load times ?

[aleks0801]

So I finally built my pc, updated the BIOS of the motherboard to the newest non-beta version and installed all the gpu, mobo, etc drivers.

The pc works perfectly fine, I enabled EXPO to overclock the ram to 6000mhz and I have a one click overclock for the GPU, that's about all I did in terms of overclocking. Games run smoothly without any issues, temps are more than perfect, 60C on ssd, 50C on cpu and 60C on GPU.

When I look at the BIOS load time in task manager, it is always between 35 and 40 seconds, and I remember my old pc having around 10 seconds.
Does anyone have a suggestion?

This is my build:
MSI X670E GAMING PLUS WIFI
KFA2 GeForce RTX 4090 SG 1-Click OC
AMD Ryzen 7 7800X3D
Deepcool AK620 WH
Corsair Vengeance 32GB DDR5-6000 CL30-36-36-76
Team Group Z540 2TB (+ be quiet! MC1 Pro Cooler)
be quiet! Pure Power 12M (1000W)

the task manager shows 35-40 seconds, but does it actually take that much time from when you click the power button, to when the Windows loading screen appears?

ddr5 with expo tends to take longer all together on a cold boot. i ran into this issue with a recent build myself, and through research; it is simply the databus stacking, so that it can run at the speeds you want or have it set at. I initially was stumped as to the boot times, because my current 5600x build only takes 14 seconds to boot.

30-50 seconds is normal for the 7000 series, from what i have read.

the build i recently did was:
asus tuf gaming x670
7800x3d
4x32gb flare @6000
2x2tb crucial T700
tuf gaming 4090
corsair rmx 1200w

If your not using BT or wireless disable that in the bios see if it makes a diff.

It does, that's gow I noticed that something isn't right. It is when I started searching for answers that I found out I can look at the load time in task mngr

That's exactly what I have read too. A few people say that some components are not runing propperly, but the majority says it is because AM5 with ddr5 and expo are brand new and needs time to be optimized.
Even with expo disabled I went from ~40sec boot to ~30sec boot, but I still wasn't satisfied, so I continued searching for answers. In the end I actually found something that helped bringing down load time to ~14sec, here is the video:

But as he said, it may cause your pc to be more unstable. For now it works like a clock, no issues just fast boots, but since all this is really new I am considering to just set it back to default and wait 40sec for a boot, it is not the end of the world

That is actually a great idea, I haven't seen anyone suggesting this. I will try that when I get home and see if it improves the times. Thank you

Bios will try to start up all adapters. If there is no device connected, the bios has a timed wait to discover if there is anything there or not.
As above, the absence of the wifi card for instance will cause a delay.
Disable all adapters that you will not use.

On ram, if the motherboard does not like the ram settings, it will delay and try to get others to work.
Use cpu-Z to verify that the expo settings actually in use match the supplied ram profiles.

Lastly, why not use sleep to ram instead of shutting down.
Sleep puts the pc and monitor into a very low power state, essentially equivalent to full power off.
Sleep and wake take only a handful of seconds. Try it and see if it works for you.

FWIW, I looked and my last bios time was 13.1 seconds.
