Motherboard With 4 Ram Slots

Nov 03, 2010 I'm looking for a laptop that has 4 RAM slots, a powerful CPU(Equivalent to intel core 2 quad series desktop CPU's or better), a screen around 1600 pixels wide. I DON'T CARE ABOUT GRAPHICS CARDS! I know most laptops in this class ship with fancy gaming graphics cards, but if there is something that has a simpler graphics card that would be better.
I'm upgrading to Skylake and got 2 sticks of 8gb DDR4 to go with the new Z170 mobo. I've read in various places that the dual channel slots furthest from the CPU (2+4) are somehow better to use than slots 1+3 if you only have two sticks.
Nov 17, 2014 Re: Adding more RAM to PC: use all 4 slots or only 2? In reply to photophile. Nov 15, 2014 I think I'd change all the ram - ram is cheap - at the same time and have x4 modules of 2Gb each.

What Ram Slots To Use

A memory slot, memory socket, or RAM slot is what allows RAM (computer memory) to be inserted into the computer. Most motherboards have two to four memory slots, which determine the type of RAM used with the computer. The most common types of RAM are SDRAM and DDR for desktop computers and SODIMM for laptop computers, each having various types and speeds. The picture below is an example of what memory slots may look like inside a desktop computer. In this picture, there are three open and available slots for three memory sticks.

When buying a new computer or motherboard, pay close attention to the types of RAM the memory slots can accept. Make sure you know exactly type of RAM to buy for your computer. It is also important to note how many available memory slots are available in your computer. It is not uncommon for computers to have all memory slots occupied. If all slots are full and you want to upgrade the computer memory, you need to remove some or all of the existing memory.

Jul 22, 2009 For dual channel you need to use 1 + 2 or 3+4, it's stated in the manual, the slots are colour coded, and even the BIOS is telling me 2 & 4 is single channel. The problem is that if I ever wanted.

Is My Ram In The Right Slot

Memory module, Memory terms

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 will help you to determine the number of memory slots in your computer, as well as how many are currently being used.

Windows Task Manager

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

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

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.

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

On the next page, select your preferred language.

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

Once the download has finished, install it from your browser and open the program.
Click the SPD tab at the top of the screen, and then click the down arrow in the Memory Slot Selection section.

Which One To Use

As you can see in the image above, all of the memory slots (in this case, four) are listed in the drop-down menu.

Tip

If you select a different slot from the drop-down menu, CPU-Z will tell you additional information about the RAM that is installed, or nothing if the slot is unoccupied.

What Ram Slots Should I Use

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 located on either side of the CPU, and resemble what is shown below.

Which Slots To Put Ram

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