ASUS ROG Strix B650-A Slow to Boot

[jimbo4ever]

I have purchased a new ASUS ROG Strix B650-A motherboard with a 7800X3D CPU and RAM; with DOCP enabled it is very slow to boot (approximately 60s). Of those 60s, it takes approximately 40s to show the POST screen. I have tried to play with the memory settings but often get a BSOD. With DOCP turned off my 6000MHz RAM is running at 4800MHz.

The RAM is CORSAIR VENGEANCE DDR5 RAM 32GB (2x16GB) 6000MHz CL30 Intel XMP iCUE Compatible Computer Memory - Black (CMK32GX5M2B6000C30).

I have upgraded to the latest BIOS (v2413)

Please can someone help?

Hello jimbo4ever

If your pc is stable with DOCP enabled, head into the bios, on the AI Tweaker page scroll until you find Dram Timing Control.

Click Dram Timing Control and enable Memory Context Restore.

This should speed up your boot time.

Hello, @jimbo4ever 

The memory overclocking settings may lead to extended boot times.
Kindly ensure the RAM modules are installed in the recommended slot and refer to the configuration provided by Nate, or boot under the default BIOS settings after clearing CMOS to confirm.

Also, upon verification, the "CMK32GX5M2B6000C30" memory is not listed in the ROG STRIX B650-A GAMING WIFI QVL.

If necessary, please cross-test the memory listed in the QVL.

Thank you.

Thank you Nate and Jiazzz for the replies.

So, this is interesting. The problem is fixed (and by following Nate's suggestion of enabling Memory Context Restore).

The strange thing is I did this fix myself on the day of the install, but I'd get a BSOD as soon as Windows loaded. However, trying it the following day worked! I have not reset the CMOS jumpers so cannot explain this. Just happy it is now working.

Hi @jimbo4ever 

Memory Context Restore saves the last "successful" memory training. Investigate memory stability with tools such as Karhu RAM Test or TM5. Saving previous parameters works in some cases, but enabling this function if the memory isn't stable can cause complications as you experienced previously.
