Good evening,
I built a new rig this week.
-An i9-12900K with Corsair H60i (replaced the SP120 with 2 ML120 Pro)
-Asus ROG Strix Z690-F Gaming Wifi
-2x16GB Kingston DDR5 6000 CL40
-Corsair RM750x PSU
-My previous 512GB Samsung 970 Pro PCIe 3.0 NVMe SSD
-My previous Gigabyte G1 Gaming GTX 1070
Once I touch the power button, the power LED doesn’t turn on, until 5-7 seconds have passed.
If I watch Q-LEDs, I can see 2-3 red LED flashes, before the yellow, white, green LED, and then screen turns on, Windows logo, and finish booting. Aproximately 40 seconds from power button to desktop.
Never seen this behaviour on my previous builds (Z170, B85 and Z77).
It’s some kind of fault? Or all of you have this behaviour?
I search in Google something like “Z690 long time post” or “Z690-F post delay” and I can see a lot of people with similar problem, and no one answer.
I was doing some tests:
-Tried BIOS 0223, 1003, and come back to 1403, absolute no difference.
-Remove both RAM sticks.
Installed one in slot 1, no boot (red light, yellow light, red light, yellow light, ... and no boot).
Installed one in slot 2, boot, but with power on delay. Installed the other one in the same slot, same behaviour.
-Disconnected PSU wire to socket. Connected again. Next time boot, no delay in power LED, it lights on inmediately, but RAM testing takes a lot of time (first red light, then yellow lite like 20 or 30 seconds, then white light and finally green light, and screen turns on.
Next time boot, the delay in power LED appear again (6 seconds until light on), and RAM testing quick, less than a second.
-Changed XMP settings. With XMP1 or XMP2 6000, same delay. Tried enter manual timmings instead of XMP profile, same behaviour.
With auto (JEDEC 4800), the delay exists, but only half time, aproximately 3 seconds.
-Disconnected USB headers and USB devices, no difference.
-Disconected M.2 disc (connected on M2_1 slot), no difference.
-Disconnected PCIe graphics card, no difference.
-Take apart, clean and reseat all the slots (PCIe, DIMM and CPU), no difference.
-Test one by one different BIOS settings (VMD disable, Storage controlers disabled, ReSize BAR enabled, disable MultiCore Enhancement, hydranode fan control disabled, Fastboot disable). None of them changed the boot behaviour.
Then, have I a problem or incompatibility with RAM?
I bought two Kingston KF560C40BB-16 (DDR5-6000 CL40). Two separate RAM modules, not a 2x16GB kit (because stock lack). They appear in the QVL. I don't think the problem is they are separate modules, because the problem remains using only one.
Maybe a CPU problem? Because the IMC.
Or a mainboard problem?
I have an extrange behaviour in Q-LED diagnostic lights.
The first two red light flashes, the power LED is turned off, then, the power LED lights on, and boot secuence starts (red, yellow, withe, green, and BIOS).
What do you think?
Anyone with the same behaviour?
Many thanks for your answers.
