The motherboard isn't recognizing any new RAM.
The motherboard isn't recognizing any new RAM.
Hello! I'm just getting started with the forums and have been following Linus for a while. Recently, I upgraded my RAM from a 2*8 GB to a 2*16 GB model—it really made a big difference, turning it into a solid professional setup. The PC part picker said it was compatible, but when I power on, I see the code 23 appearing on my board. Could anyone help clarify what that means or how to resolve it? Thanks!
You haven't attempted resetting the CMOS or checking fundamental troubleshooting steps.
Did you check for a recent update before setting up? Crucial states that Crucial Pro supports 8Gbit or 16Gbit densities, with 16Gbit chips only working on 8th/9th generation PCs (refer to details). Their setup tool usually suggests 2666 or 2400 modules, likely because those are the older ones that use older dies. Kingston advises using dual rank 16GB modules to prevent this compatibility problem.
The thread suggests 23 might mean 2B, which could be a memory mistake, so it matches. Ensure all DIMMs are fully inserted into their slots and the clips are fully closed. If that fails, remove one DIMM, test, then try the other. Consider moving RAM to the outer slot pair on the motherboard (e.g., IOIO for CPU) instead of the inner pair. If nothing works, replace the old memory as a backup, confirming it's not a hardware issue. Clearing CMOS might also help.
My profile is the most recent update. I'll check for compatibility with density settings.
From observing the sticks, you can see what the heat spreaders are protecting. If they have a single side (eight memory chips), they’re probably 16Gbit. For a dual side setup (sixteen memory chips), it’s likely 8Gbit.
I've attempted to reset the CMOS and install RAM one stick at a time. It hasn't worked. Now I'm trying to install all my RAM—both old and new—so the system boots up and recognizes everything. Of course, it only sees the slower 2133 MHz version. Could your PC be struggling to detect the faster RAM due to the CPU? It’s upgrading from an i5-6600 to an i7-7700 in a few days once it arrives. I’ll need to check that later.
Sounds like a issue with compatibility, tough have you tried to basic 1 stick at the time? That should boot unless not compatible, sadly RAM compatible for early DDR4 boards not that good just like with early Ryzen boards... Edit: when putting mixed RAM it can be finicky sometimes which slot they are in can make or break it from working, I had a board that refused to boot onless I had mixed RAM sticks 1 per channel for some reason LMAO.
