RAM Slots
RAM Slots
System OEM/Model: HP Pro 3400 MT Motherboard: Foxconn 2abf CPU: Intel i7-2600K GPU: PNY GeForce GTX560 ti RAM: 2x 2gb BIOS reports only 2GB available, RAM tests show 4GB total. The issue is why my system uses just one RAM slot despite having two slots.
No, the additional 2GB is allocated for storage, not directly to your CPU.
Perfectly, the data should go straight to your CPU. If 2 GB are marked as reserved hardware, it might indicate a problem with the system settings in Windows: https://appuals.com/windows-10-wont-use-full-ram/
I'm using Windows 7, please check if it works for you and see how I can help.
Are the DIMMs identical and have you checked them separately? This isn’t always required, but some DIMMs don’t work well together. It might also relate to BIOS settings (though I’m skeptical it can be fixed if that’s the case). If you haven’t already, confirm your BIOS is current. If the problem isn’t related to a DIMM or BIOS, try running the 2600K on another motherboard—ideally not a prebuilt one—to rule out a memory controller issue. I have a Celeron G440 with a similar problem.
