16 GB memory available, yet just 8 is functional. 8 resources locked for use.
16 GB memory available, yet just 8 is functional. 8 resources locked for use.
Good afternoon! Thank you for reaching out. I understand this is taking a while, and I'm here to help. After gathering everything, I still can't get the system to utilize the full 16 GB of RAM. I've tried several steps: checking MSCONFIG, adjusting memory settings in REGEDIT, booting with one stick separately, running the Windows Memory Diagnostic, and looking into BIOS memory sharing options. I'm guessing the motherboard might be too basic, so manually tweaking timers or configurations could help. Please find my full system details below, and feel free to share any screenshots you have. Thank you!
The memory controller and board likely dislike the memory kit setup. Check the Jedec timings—consider the CL22 speed and see how it handles 2133mhz with a CL15 XMP profile at 3000mhz. Look for gear down mode in the timings and turn it off to test. It might indicate hardware incompatibility, possibly due to the board. If you're unsure, try using a different CPU or memory kit for easier troubleshooting. You could also bring it to a shop for testing if you don’t have extra equipment.
Check the screenshots... Running dual channel in Slots 2 and 4. Note: And I have to say, that's the absolute top-quality first post I've seen in a long time. If I were an admin (though I'm not), I'd definitely give this person some VIP access for a day or two, haha.
Hi! Thanks a ton for your help @ShrimpBrime It sounds like a unique situation, especially since I'm matching a mid-range RAM with the cheapest motherboard I found on Amazon. Can you assist me with the XMP profile setup? I'm not very familiar with it and the BIOS only has "Off" or "Profile 1." If I set it to "Profile 1," the PC won't even boot and I need to reset the CMOS using a jumper. I'm not interested in trying different CPUs or RAM right now because the local shops only sell DDR3, which feels outdated. @Dudeinfire99 There really isn't much room for error—your motherboard only has two slots, but it shows four. I've attached some screenshots of the BIOS and a photo of the PC just in case. Thanks again!
The physical RAM size is unrelated to the dual channel setup. The OP's new board features just two slots, meaning only those can be utilized. It might be the memory controller inside the CPU; consider reinstalling the CPU and CPU cooler, or installing a fresh Windows installation.
It's fine. Just checking his task manager. The board sees 16GB, but Windows is using 8GB, which means the remaining 8GB is available for the end user.
