    Dreaded Detect Memory error after wake from sleep and reboots

    Wondering if anyone else has this issue on R6EE. Running a 10940x @4.6ghz 100% Prime95 stable. Memory is Patriot Viper 4400 that I am running at 3800 17-18-18-36 2T which is testmem5 anta777@Extreme stable pass after pass after pass as those timings are crazy loose for this memory.
    Right now I have not had a Detect memory error in over a week and tonight after a wake from sleep I got it. did the try again button and still had the error.
    Power Cycled the system and still had the error and eventually had to do the safe boot button to get into bios and reboot from there with no error.

    I have the uncore at +0.300mv so I am not sure if the CPU is just having issues or this motherboard does not like this RAM. Currently on the latest BIOS.

    Like I said this system is 100% rock solid stable at my current settings which are well below the settings I run when I am doing benchmarks.

    Not sure what causes the issue or what steps to take to try and diagnose it if all my stability test prove stable.

    DId you try to adjust DRAM voltage higher from 1.35V to 1.37 or higher until the detect memory works! You might have to downclock the CPU as well to see if it works!
    Sincerely,

    Then something is definitelly not 100% stable. I had the same situation with 4000MHz g.skill memory on VI Encore. Finished memtest86 without errors, same about games etc... But still had cold boot memory detect from time to time. Lowering MHz fixed this issue.

    I guess it's possible. This being a 4400 kit that I am running at 3800 mhz shouldn't be a problem but maybe this IMC on this 10940x is just really that bad.
    I'll do some more testing and see what happens.
    I don't think it has anything to do with the CPU clock personally.

    I "Think" I might have this figured out, I decided to raise VCCIO/VCCA up to 1.15 along with the memory back at 4000mhz and so far I have not had any Detect memory Errors.
    Doing this I can now actually get the Board to boot with the RAM at 4200 but Windows does not like it. With the VCCIO/VCCA on Auto 4200 won't even boot at all.

    Wake from sleep issues when overclocking is normally related to the VCCSA and VCCIO rails, yes. If the issue continues, consider relaxing tRFC and tREF
