I’m wondering which slots my RAM should go on Gigabyte b450m ds3h. Manual says: Dual Channel Memory Configuration This motherboard provides four memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. This page describes the RAM specifications for many of the MacBook laptops. In the section for my laptop (13″ Pro, Late 2011), it says: Additional Notes: For best performance, fill both memory slots, installing an equal memory module in each slot. If you have 2 sticks of RAM, you'll start from the slot closest to the 24-pin and put one in that slot, skip a slot, and then the second RAM stick will go in the third slot. If you only have 1 stick of RAM then it will go in the third slot from the 24-pin. With equal amounts of memory in both slots, memory can be interleaved so that successive chunks of memory alternate slots. That way, memory access gets distributed to both slots almost perfectly evenly, allowing their bandwidth to combine. With uneven amounts, memory cannot be interleaved and has to be mapped first to one stick and then the other.

When a user wants to add or upgrade memory (RAM) in a computer, they need to know how many memory slots are available. The following section helps you to determine the number of memory slots in your computer, and how many are used.

Windows Task Manager

The easiest solution for Windows users is to open the Windows Task Manager.

1. Press the Windows key, type Task Manager, and then press Enter.
2. In the window that appears, click the Performance tab (A), then select Memory (B).
3. In the lower-right corner, the number of slots is displayed in the Slots used: section (C).

4. As you can see, this computer has a total of four memory slots, although only two are currently being utilized.

Use the CPU-Z utility

Another way to get information about memory slots and details about the RAM currently installed on your computer, is to use the free CPU-Z third-party utility.

1. Open an Internet browser and visit the CPUID website.
2. On the left side of the screen, select your operating system.

3. On the next page, select your preferred language.

4. On the next screen, click the DOWNLOAD NOW! button.

6. Once the download has finished, install it from your browser and open the program.

7. Click the SPD tab at the top of the screen, and then click the down arrow in the Memory Slot Selection section.

8. As you can see in the image above, all of the memory slots are listed on the drop-down menu.

If you select a different slot from the drop-down menu, CPU-Z will tell you additional information about the RAM that is installed.

Examine the motherboard

Sometimes the best way to determine the available memory slots is to open the computer and examine the motherboard. Opening the computer is the best option if were unable to get the Windows Task Manager or CPU-Z to work.

Looking inside the case, the motherboard is the primary large circuit board. On most motherboards, the memory slots are on either side of the CPU, and resemble what is shown below.

Most computer motherboards have two, three, or four memory slots. Some higher-end motherboards have as many as eight. The above motherboard picture above has no memory modules installed in any of its three slots.

Memory Slot Not Reading Ram

If your computer has no memory slots available and you want to upgrade, you must remove and replace some of the existing memory.
