One of the two RAM sticks isn't being recognized as functional.
CPU model: Ryzen 7 1800x. RAM: Gigabyte x370 gaming K5. I've had these functioning well for two years until I noticed they were only reaching 2133MHz instead of the full 3000MHz. I tried increasing the RAM speed in the BIOS, which resolved the issue. However, after that change, Windows was only detecting half of the available memory—about 7.9GB out of 8.1GB. This seems excessive, so I'm attempting a fix. My steps so far: 1. Updated BIOS and chipset correctly. 2. Placed RAM sticks in all unused slots on the motherboard. 3. CPU-Z only shows one slot with 8GB, yet total memory is 16GB. 4. ICUE software detects only one color option, even after rearranging RAM. 5. Used msconfig to adjust memory settings at startup. 6. Running Windows 10 x64, no memory limits. 7. Restored RAM speed to 2133MHz, but the problem continues. Any advice? Thanks, Sean.
It seems one of the sticks is no longer functioning. Does this particular stick remain inactive and undetectable or unresponsive in any slot? If yes, then it’s likely dead. You might want to refer to your motherboard manual to find out the correct slot for your RAM, though you mentioned you’ve checked all slots already.
You're asking about the specific RAM model you're experiencing issues with. Corsair displays a unique code on the stick, and this often indicates a compatibility or speed limitation problem. The advice suggests gradually increasing the memory speed from 2133 MHz to avoid triggering the issue.
It's a Hynix AFR model, not the top choice for Ryzen. It seems odd it functioned at 2133 initially but then stopped. Would you like to try inserting just one stick and then swapping it to see if one fails?
