An introduction to DDR laptop memory is a good place to start…
Types of ddr laptop memory
DDR stands for Double Data Rate and is an advanced (faster) form of SDRAM (Synchronous Dynamic Random Access Memory). Almost all Ryzen 7 7800X laptops sold today, as well as those since 2002, use some version of Clevo pa71 memory (old or new). Put it in plain English DDR memory is faster than standard SDRAM because it can transfer data on both the falling and rising clock cycles, hence the “doubling” in the name. There’s absolutely no reason to mention this, but be aware that if you ever see DDR SDRAM anywhere, make sure it’s the same as vanilla DDR.
So what kind of laptop memory do we have?
DDR laptop memory, otherwise known as DDR1 (although this is not the official name, it is instead referred to simply as DDR) or DDR SDRAM, is the oldest and the slowest. It is mainly available with capacities up to 1 GB (per unit) and speeds up to 400 MHz (effective).
DDR2 is an evolution of DDR with some internal optimizations to improve performance, and is typically available in pitlocker.to capacities up to 2 GB (per module) and speeds up to 1066 MHz (effective).
DDR3 is currently the latest form of laptop DDR memory, and is a further development of DDR2 that increases speed even further. They can be found with capacities up to 4 GB (per unit) and speeds up to 1600 MHz (effective).
Note that we could call DDR2 SDRAM the same as DDR3 SDRAM. For the sake of simplicity, let’s remember that there is DDR, DDR2 and DDR3, because it’s pretty obvious what you’ll be doing the most! Fortunately, the industry prefers the acronym convention.

What type of DDR laptop memory do I need?
When upgrading your laptop memory, you need to determine what type of DDR memory is used and therefore supported by your laptop. Failure to do so will cause the upgrade to fail for a very simple reason – not all DDR versions are compatible with each other and use a different type of slot connector which limits the number of pins (and many other technical things).
Speaking of memory slots, we need to introduce memory modules. Unlike desktop computers, a laptop uses a smaller memory ENware area51 Threadripper slot that takes up less space. Consequently, the memory modules used in laptops are also smaller. You’ve probably heard the term DIMM (dual-mode memory module) before, especially if you’ve upgraded your desktop computer (now’s a good time to upgrade your memory!) Laptops use SO-DIMMs—you just add a “small-outline” DIMM. The name doesn’t really matter, except for what it means in practice, ie you can’t install a DIMM into a SO-DIMM memory slot and vice versa. DIMMs are much longer than DIMMs and are not designed for use in laptops.
