Hello!
My system has an i7 9700KF CPU, Asus Prime B360-Plus (latest BIOS) with 4 modules of 16GB DDR4 Kingston KVR26N19D8/16. The issue is as following: at cold boot (system unplugged from power source) from the moment I press the power button the CPU fan starts spinning, the LEDs from the motherboard come alive, but the starting beep and the POST screen appear after 23 seconds. I pulled out 2 modules of RAM and the delay shortened to 16 seconds.
Additional info:
1. I also use an old video card that will not boot using UEFI, and for which the BIOS loads CSM module
2.Only 2 modules of RAM work with RAM setting on auto. If I plug all 4 modules with settings on auto the start time increase to 1-2 minutes, the RAM will run at 2133MHz, and CL will be set at 15 in BIOS (despite the fact the modules have CL19). I used AI Tweaker and changed the values of CL, tRCD and tRAS to the correct values (19,19,43, from CPU-Z) with 2 modules installed, and after that I added the next 2 modules.Apart from that delay at start, the RAM runs at 2666MHz without any issue.I used TestMem5 as stress test and there were no errors.Also scanned all the 64GB of RAM with Windows Memory Diagnostic, and with MemTest86+.No issues.
3.The XMP otion is disabled and cannot be enabled, even if I use only 2 modules of RAM
Is there anything I can do to decrease that delay? I understand that other users have no delay from power button press to POST screen. My old ASUS P5QL Pro with Core 2 Quad Q9550 had no delay from Power Button to POST screen (4 modules of 2GB DDR2).
