Ram Slots Matter

Summary :

• If you have DDR3, you shouldn’t use it with DDR, and so in the different types of RAM. This is the easy part because they will not fit into the same slots. Now, RAM is a bit more complicated than that. If you do mix RAM size, you need them to have the same voltage in order for them to perform at optimal levels.
• 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.
• A memory slot, memory socket, or RAM slot is what allows RAM (computer memory) to be inserted into 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. Does RAM have to be in first slot?
• If your CPU and motherboard support quad-channel RAM, however, you can be a bit more flexible. Two sticks of RAM will only run in dual channel mode, halving your theoretical bandwidth, but assuming you would have purchased the same total capacity, you have more RAM slots free for potential future upgrades. Tip: You should never mix RAM speeds.

You might need to enable the XMP profile in Bios in order for the RAM to run at full speed. Also, if you set them in the other slots there will not be any problem, but you will have less air.

It is extremely important to make a RAM compatibility check when purchasing a new RAM, right? If the RAM is not compatible with your motherboard, your computer won’t run as normal. How to check RAM compatibility? Let’s explore this question together with MiniTool.

Why Check RAM Compatibility

Does RAM matter? RAM is an integral component of your system. Once your RAM gets damaged or incompatible, your computer will not operate properly. It is necessary for your processor to run an operating system and different programs on the computer.

Usually, the more RAM you have installed, the faster your processor can handle and the more process your computer can run at a time. However, the RAM storage capacity depends on your motherboard specs can support.

So, it is necessary to make a RAM compatibility check before upgrading RAM. How to check RAM compatibility? Is my RAM compatible with any motherboard? Please keep reading to get the answers.

Is My RAM Compatible with Any Motherboard

When it comes to RAM compatibility, it is inevitable to discuss the motherboard. In fact, the RAM compatibility checking depends on what motherboard you have installed. As is well known to us, there are all types of RAM memories such as DDR3, DDR4, and so on. Not all RAM chips can mix and match the memory slot of your motherboard.

For example, if your motherboard was designed for DDR4 RAM, the memory slots of your motherboard cannot fit other types of RAMs like DDR3. Besides, the motherboard memory slots usually are integrated into the board and cannot be changed.

So, it important to make a memory compatibility check on your motherboard.

How Do I Know My RAM Compatibility

How to check RAM compatibility for your computers? Your operating systems and motherboard are 2 important components that have great significance on the RAM compatibility. So, you need to know your system information first. After that, you can refer to the following information to make a RAM compatibility check.

Here’s a way to check your Windows 10 system information.

Step 1. Press Win + E keys to open the File Explorer.

Step 2. Right-click This PC on the left side and select Properties to open the system information window. Then you will see the current Windows edition as well as the system type.

The operating systems will affect the maximum capacity of RAM you can use on your computer. Compared to the consumer editions, a typical server Windows version can support several times the maximum RAM.

Usually, the Windows 8 Enterprise and Professional editions can support a maximum of 512GB RAM, while the consumer version only supports up to 128GB. Windows 10 operating systems have similar RAM limits. You can refer to the information from Microsoft.

It is different between a 32-bit and 64-bit processor as well. Without considering the Windows editions, a 32-bit system has the limitation of 4GB physical memory, while a 64-bit system can be able to handle a 128GB RAM physical memory.

In addition, your motherboard also determines how much RAM your computer can support. This is because your motherboard has a memory module slot limit. If you don’t know how to check the motherboard model, please read this post.

Here are several common memory types that you can refer to:

• DDR 2 SDRAM: This technology is commonly found in those computers that are made after 2003.
• DDR3 SDRAM: It is suitable for those computers made after 2007.
• DDR4 SDRAM: It is the newest RAM type. So, please make sure you are using a modern PC with the latest builds.

Is it possible to fix laptop memory slot failure with a guitar pick? Yes, it is. You will not fix the memory slot itself, but you can work around the problem. 🙂
Today I received a Toshiba Satellite Pro 4600 laptop with the following complaint:

Types Of Ram Slots Socket

The laptop starts and works properly, but recognizes only one of the two memory modules installed. The laptop has two 256MB RAM modules installed, but registers only 256MB.

First of all, I removed the memory cover to find out if both memory modules are installed correctly. The laptop had two 256MB Kingston modules installed and they were seated properly.

When I started the laptop and entered the BIOS setup menu, I found that only one of the two memory modules is detected and the laptop registers only 256MB (262144KB) of RAM instead of 512MB (524288KB).
Just a side note. In the computer world 1MB=1024KB. That’s why 256MB=262144KB and 512MB=524288KB.

I tried reseating both memory modules but it didn’t help.
After that I tried installing both memory modules in both memory slots one by one and here’s what I found. The laptop worked absolutely fine when both memory modules were installed into the slot A, but failed to boot with both memory modules installed into the slot B.
Apparently, there is nothing wrong with the memory modules and the laptop has a faulty memory slot B. The memory slot is permanently soldered on the motherboard. If one of the slots fails you’ll have to replace the whole motherboard or use the laptop with only one working slot.
Buying a new motherboard for this older laptop wouldn’t make any sense because it’s too expensive, but the laptop is still in a good working condition except the faulty memory slot B, so I continued playing with that trying to find the solution.

I noticed that the laptop start normally with the memory module installed into the faulty slot if I slightly press on the module with my thumb. And this gave me an idea.

This guitar pick is going to fix my laptop. 🙂

I installed both RAM modules back into the slots and then placed the guitar pick over the module in the slot B as it shown on the picture.

I thought if I close the RAM door it will press on the guitar pick/memory module and it will have the same effect as pressing on the module with my thumb. And it worked!

Both memory modules were detected properly and the laptop registered all 512MB. After “the fix” I tested memory with Memtest86+ and the laptop passed the test.
I wouldn’t call it the best solution for fixing a faulty memory slot but in some cases it will work.

By the way, I didn’t charge the customer for this “repair”, he knows what is going on and how I “fixed” his problem.
