Question Every few days, I have to reseat my RAM to get PC to boot

Hey guys, first post here or any pc forum actually, so sorry if this has been asked a million times, but I couldn't find any posts where people were having my same problem.


So the issues I'm having is that every few days after putting my PC to sleep for the night, when I get up in the morning the motherboard (Asrock Z390 Taichi) will display error code 55, which means no RAM is detected.

I have 32gb (4 x 8gb) and in order to get it to reboot I have to pull out atleast one stick of ram, boot it up like normal, shut it down, reinstall the ram stick I removed, and then boot it again and it always boots up fine with all the ram installed after doing these steps. And on task manager and CPU-Z it shows all 32gb is installed.

I have tried rearranging the ram sticks in different slots, booting with 1, 2, or 3 of the sticks in, etc.. and I can not recreate the error. The only times it happens is randomly overnight, around every 3-4 days.

I did recently update my BIOS, but only after I received this error the first time (thought it might be a BIOS version error). After updating the BIOS it worked fine for a few days, and then went back to doing the same thing.

If anyone has any tips on how I might be able to fix this issue, I would greatly appreciate the help.



I'll list more full specs below:

i9-9900K

Asrock Z390 Taichi

Corsair RGB Vengeance DDR4 (4x 8gb)

(The clock speed on task manager shows it running @ 2133Mhz, but I cant seem to find this model of ram online listed at that speed, maybe that has something to do with this issue? I believe what I actually have was advertised at 3200Mhz)

Gigabyte RTX 2080

EVGA supernova G3 850 Watt gold PSU

Couple SSDs and a HDD, not sure if relevant to this problem so I wont bother listing them out.

(I had a friend build this PC for me, so I apologize I'm a little out of the loop on all the details, but I'm trying to learn more and I'm hoping to build a rig myself in the near future)


Thank you guys for any help you can provide!
 
Just wanted to put an update here, I went into bios and was playing around with the RAM clock speed, it was originally set on "auto" and I saw a thread on here about ram running slow and they recommended switching from "auto" to "XMP profile 1." I made that switch in the bios and now task manager/CPU-Z show my clock speed @ 3200Mhz.

Not sure if that was the root issue here that was causing this weird error every few days, but hopefully that will fix it.
 
I hope you've found the solution, but if not, see if not using sleep and instead shutting down the system overnight fixes the issue. sleep and hibernation have their own issues...

Thanks for the heads up. The first time it happened I used hibernation mode, and then vowed to never use it again because I thought that was the cause. but now its happened a few times using sleep mode as well. Probably best to just turn it off.
