[HELP] Double boot trouble on ASUS ROG STRIX B760-I + i7 14700

[ifa77]

Hello,

PC Setup:

• ASUS ROG STRIX B760-I GAMING WIFI
• ASUS TUF RTX 4090 OC
• Intel Core i7-14700
• Monitor Dell S2522HG

I've recorded a video where you can see how it starts up, including the POST light.

Behavior Observed:

• The PC starts up on the second attempt when it has been turned off for a long time (e.g., overnight).
• If I restart it, everything is fine; it starts as it should.
• If I shut it down and then start it up again, it starts as expected.

So, I only notice this problem when the PC has been turned off for an extended period.

Troubleshooting Steps Taken:

• I tried to find the "Fast Startup" option in Windows to turn it off, but Windows 11 no longer has this option.
• Someone mentioned that the monitor could power the motherboard, making the motherboard think there's a power leakage, but I don't know how to check this. I have USB ports on my monitor and I turned them off when the monitor is shut down, but it didn't help.

Are there any other possible solutions?

(Just in case, the AIO mounting is a temporary solution; I'm waiting for another AIO.)

I'm not sure why you are seeing different behaviour overnight, but are you turning off the PSU in that scenario? 

Also, I think that Windows 11 does have the fast startup option. Use a CMD window in admin mode and try:

powercfg /h off

In addition, you'll find a fast boot option in the BIOS. If enabled, I think this skips memory training. That might be worth a try as well but I think it's on by default anyway.

powercfg /h off

Just tried it, then shut down PC for 1h and it didn't help.
Later I'll try to turn off fast boot in BIOS.

Hi,

When you say extended period, has the AC been cycled in this time? Some controllers need a power cycle and it can depend on the memory configuration also.

has the AC been cycled in this time?

---

- I didn't turn off the power supply
- No power loss, power is available

I might add that the power is coming from a surge protector (extension cord), with other appliances connected to it. Also here are my boot settings, I'll play with it later.

Just found out that I have DDR5 RAM with an AMD DOCP profile 🤡 (I have an Intel CPU) and it was turned on in the BIOS.

Can it be a problem?

[Silent_Scone]

No, not a problem. The profile will just load the VDD and VDDQ voltages and memory timings as it would on an AMD based system. However, using a memory kit that has been binned by the memory vendor for another platform may make it more likely that manual tuning is needed to find stability.
