B650E-F takes over 5 minutes to boot into Windows

Hi Everyone!

I was wondering if anyone else got a similar issue with B650E-F taking over 5 minutes to load into Windows with both EXPO enabled or disabled. 

I have conducted a series of test runs with different settings and even bought another RAM kit but all of them unfortunately show very long initial boot time from power off to Windows login varying from 5 minutes 30 seconds (the fastest) up to 6 minutes 20 seconds (the slowest).

G Skill Trident Z5 Neo CL 30 (Expo II enabled, 6000 Mhz) - 06:20 - run 1

G Skill Trident Z5 NeoCL 30 (Expo II enabled, 6000 Mhz) - 06:20 - run 2

G Skill Trident Z5 Neo CL 30 (Expo II enabled, 6000 Mhz), memory context restore enabled - 05:32 - run 1

G Skill Trident Z5 Neo CL 30 (Expo II enabled, 6000 Mhz), memory context restore enabled - 06:15 - run 2

G Skill Trident Z5 NeoCL 30 (Expo disabled, 4800 Mhz), default bios settings - 05:30 - run 1

G Skill Trident Z5 NeoCL 30 (Expo disabled, 4800 Mhz), default bios settings - 05:31 - run 2

Corsair Vengeance CL 30 (Expo disabled, 4800 Mhz), default bios settings - 05:31 - run 1

Corsair Vengeance CL 30 (Expo disabled, 4800 Mhz), default bios settings - 05:30 - run 2

Not sure if I'm doing something wrong in the bios settings but such a long boot time was a very unpleasant surprise after upgrading from a trusty Gigabyte Z490 and i5 10600k which took ~15 sec to load to Widnows logi n screen.

Considering returning the mobo.. Any advise is welcome.

Hi @Jiaszzz_ROG , thanks for the reply and good advice!

My problem looks to be solved now - I’ve run 4 more tests yesterday, all with below 30 seconds startup time.

What I did was quite simple but counterintuitive: in Windows Power Options > Choose what the power buttons do > Change settings that are currently unavailable I’ve disabled “Turn on fast startup” feature and it’s been working fine after it:)

I might do full diagnostics as you suggested at some point next weekend, but the boot times look good to me now.

Hello, @dyne1512 

May I ask if the situation you described happened after any changes were made? For example, adjusting the BIOS settings or connecting an external device
Does clearing CMOS and booting into the system under default BIOS settings also result in a wait time exceeding 5 minutes?
If so, please try verifying the boot speed with only the CPU, RAM (without overclocking), GPU and PSU installed before adding the system disk to check for any differences.
Meanwhile, if you haven't updated to the latest version 2413 released on February 7, 2024, please consider updating and clearing CMOS before rechecking again.
Additionally, please confirm if the currently installed memory is listed in the QVL of the ROG STRIX B650E-F GAMING WIFI and the recommended slots.
If necessary, please cross-test memory from the QVL or another system disk.

Thank you.

Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience.‌‌‌‌ 🙂
