Windows 11 with Intel i7-12700k and MSI Z690 Carbon Wifi Trident.Z DDR5 6000mhz 2x16gb MSI RTX 2070 ARMOR. RAM issue: previously both sticks functioned, now only one operates at 4800mhz. I've adjusted RAM positions, reset CMOS, updated BIOS, and performed a full PC reset. Recently upgraded from an older system; everything worked fine initially. I attempted to move my downloads folder and mistakenly renamed "C:\Users\(username)" to "Downloads." After changing the name via regedit, a restart resolved the issue. However, I'm unsure if this fixed the problem. Upon powering on, the system displayed only 16GB RAM installed. In BIOS it showed one stick in a single slot, while dual-channel was enabled on slots 2 and 4. Even after resetting the PC, BIOS updates, and troubleshooting steps, only one RAM stick functions. The other remains inactive in any slot. One stick lights up while the other doesn't, and when rebooting with the faulty stick, the motherboard displays a RAM error code E0. I have no further options and am uncertain whether to return a replacement, the RAM, or both, especially since it previously worked without issues.
Initial problem, the CPU only accepts up to 4800 DDR5. Later issue, many makers skip updating QVL lists to stay current, but your memory package isn't listed, so compatibility and stability aren't assured. There could be a valid reason the kit isn't included. I currently have an Asus board in RMA that failed after POST due to a DRAM error. It turns out the RAM I had wasn't on the QVL list and my configuration didn't match what was supported. The tested DIMMs worked fine at full speed, but one failed during the RMA and now prevents booting. Some might say RAM is just RAM, but I don't agree—especially with the wide variety of timings and voltages available today. Edited August 5, 2022 by An0maly_76 Updated, more details
It's curious you checked compatibility before. The issue might stem from changes in system requirements or compatibility limits, not just poor setup. Whether it's the motherboard, RAM, or CPU depends on your specific components and their specifications. Consider testing with a different configuration if possible.
Yeah, I didn't either, since mine worked fine until it started failing to POST. And even then, as long as it got past POST (failed about one of every eight to ten cold boots), it ran like a striped-a**ed ape. Now, you may ask what a striped-a**ed ape is. Well, have you ever seen one? Neither have I, so they must be pretty fast. Seriously, though. If your processor and / or board doesn't support your RAM at its full speed, you are pretty much guaranteed to have problems. I think having an unsupported RAM kit running at a speed that it couldn't even run the supported kits at in my configuration (limited to 2x8 or 1x16, I had 2x16) led to pushing an already flaky Integrated Memory Controller over the edge. Turns out one of those sticks threw in the towel today, and it tested fine in the other board. EDIT: You might try disabling XMP / DOCP settings to see if it stabilizes at the default RAM speed. Could be a quick fix, but no guarantees on that. Edited August 5, 2022 by An0maly_76 Revised, more info
It seems the issue persists regardless of how I rearrange the RAM modules or toggle XMP settings. Unfortunately, I’m still able to cancel the purchase and lower the speed if necessary because it won’t work. I’m unsure whether I should replace the motherboard or RAM, or simply refund my current RAM and switch to a compatible speed. I wish I could try another DDR5 RAM package to identify the problem and save time.
Here’s a revised version of your text:
If you’re looking for alternatives that are clearly backed, there’s nothing definitive that confirms they won’t work. It’s always a bit stressful waiting to see if your RMA or warranty gets canceled due to something unexpected.
It's not great, but I believe refunding the RAM and switching to a DDR5 4800 with the highest supported speed would be the best choice. It won't hurt performance much, and it keeps things stable. A solid build is safer than an unstable one that might fail later. Should I replace the motherboard too, or just trust the next model? Or should I go all-in and swap both components?
It's unlikely the motherboard will significantly impact performance. Consider turning off XMP/DOCP overclock features and test if it improves things. For additional RAM, refer to the QVL compatibility list for your board—search for part numbers matching your CPU speed and start experimenting.
