Fully clear the UEFI and boot at stock settings. If all the memory is then properly detected you need to correctly tune the system for the chosen memory speed or run at a lower frequency that is within the capabilities of the IMC without the additional manual tuning.
Hello ROG Forum!
I am sad to report that 4GB of my 16GB has gone missing again. I assume that it's from channel C.
I am asking for the forum's advice on how to proceed. I'm running an RVE on 1901 and have 4 sticks of Dominator Platinum 3000 at 1.38v. (0.03v over stock)
How do I proceed to fix this? Or do I have a broken board and need to start the RMA process?
Please advise. Thanks!
As Praz says, this is pretty typical symptom of an unstable overclock. Revert to stock, confirm memory is present. If not. Re-seat dimms and repeat. Then once all are present, work back up to the best frequency vs voltage setup your hardware will tolerate
I have had where multiple ram slots will stop reporting, even when not overclocking the RAM and running only on XMP.
I usually just reset to optimal settings > reboot and they come back and then setup my overclock again. It is a silly little "feature" many of these boards have and have had it happen even when I was doing no overclocking but just setting up RAID.
