Description

DDR4 3200MHz SODIMM DDR4 3200MHz DIMM DDR4 2666MHz SODIMM DDR4 2666MHz DIMM DDR4 2400MHz SODIMM What’s the difference between DDR4 and other types of memory and can I use them interchangeably? No, DDR4 memory is not compatible or interchangeable with other types such as DDR5, DDR3, and so on. Each memory type uses different slot designs, voltages, and architectures, so your system must support the memory type specifically. What’s the difference between DIMM and SO-DIMM memory? DIMM and SO-DIMM represent two different physical sizes of memory. DIMM is the larger type used in standard desktop computers. SO-DIMM is the smaller type used in laptops, mini PCs, and compact systems. They are not interchangeable. What does "Non-ECC" mean and do I need "ECC" memory instead? Non-ECC (non-error correcting) memory is required for most laptops and desktops. ECC is typically only used in servers or workstations and is not interchangeable with Non-ECC memory. If your system doesn’t mention ECC support, you need Non-ECC. How do I know which speed to choose? Each system has its own max supported speed. If the memory is faster than your system allows, it will automatically downclock to that max speed, meaning it's safe to buy faster memory. To confirm the max supported speed, refer to your system's manual Is this compatible with my system or computer? Refer to your system's manual to confirm the supported memory type, capacity, form factor, and ECC support. If you're unsure, contact our support team, we're happy to help you find the exact memory your system needs! A-Tech is a leading brand of Computer Memory (RAM) based in the United States. We offer a vast variety of memory products to solve all your memory needs; from servers to desktop PCs to laptops and more! All A-Tech products are rigorously tested to ensure high quality, dependable performance. Upgrade your system with confidence with A-Tech memory (RAM). Memory (RAM) gives applications a place to temporarily store data which allows your computer to quickly access information. Using multiple programs/applications at once or doing resource intensive activities (such as video/photo editing, gaming, programming and more) can slow down your system as each compete for a limited amount of memory resource. A RAM upgrade can improve performance by expanding your system's memory capacity allowing your computer to take on more while maintaining a fast and smooth experience. There are many types of RAM including RD, SD, DDR, DDR2, DDR3, DDR4, and DDR5, with DDR5 being the newest version. All system’s have their own memory requirements and will only support one of those specific types of RAM. For instance, a laptop that requires DDR4 RAM can only support DDR4 RAM. Each type of RAM has different pin sizes and notch locations meaning a DDR3 RAM module will only fit into a DDR3 RAM slot and so on. Refer to your system’s manual to determine the supported RAM specifications Along with RAM types, there are also different Form Factors or physical sizes of RAM. SODIMM (or SO-DIMM) RAM is used in laptops and notebooks and is also commonly used in select All-in-One (AIO) computers, Mini PCs and NAS systems. DIMM RAM is used in Desktops Computers as well as Workstations and Servers. The two sizes are not interchangeable; a DIMM module will not fit into a system that requires SODIMM RAM and a SODIMM module will not fit into a system that requires DIMM RAM. Non-ECC Unbuffered (or simply Non-ECC): Primarily used in Desktop PCs, Laptops, All-in-One (AIO) computers, & Mini PCs as almost all those system types only support Non-ECC Unbuffered memory ECC Registered: Only used in Servers and select Workstations ECC Load Reduced: Only used in Servers and select Workstations ECC Unbuffered: Only used in Servers and Workstations ECC Fully Buffered: Only used in select Servers that support DDR2 RAM Different ECC types cannot be mixed within the same system, only one type can be used.

  • Good RAM so far
Size: 32GB Kit (2 x 16GB)
So far so good. My laptop, ASUS Tuf 15 needed more RAM, it had the slots. This brand is not as well known as Crucial, but it works fine. I will need more time to check for reliability, but installation was easy and worked as expected so far.

  • Memory Boost 16 GB to 32 GB
Size: 32GB Kit (2 x 16GB)
"Excellent! I upgraded my Dell Inspiron from 16 GB to 32 GB of memory, and the difference is remarkable. I was also able to use the old 16 GB stick to upgrade an older 8 GB Dell laptop, and the performance boost there was just as noticeable. Recommended!"

Snapped into my laptop easily. HP 14m-dxlxxx laptop recognized the 16GB DDR4 RAM sticks right away. Went from 8GB to 32GB and WOW! Be sure to buy LAPTOP not DESKTOP

Significant boost in gaming performance after installing this RAM. My original mini PC came with 16GB, and now I have 32GB after my upgrade. My first time ever purchasing this brand, and I am very pleased with it.

  • Wrong MHz will give you BSOD
Size: 32GB Kit (2 x 16GB)
BUY THE CORRECT MHZ FOR YOUR MOTHERBOARD. After running Memtests, these sticks work. Just be sure to purchase the appropriate MHz speeds for your motherboard. Originally, I bought these at 3200 MHz because the Crucial website recommended it (Don't trust Crucial), but the motherboard maxes out at 2666 MHz. The CPU would throttle the speed down to the correct speeds and occasionally display the BSOD during intensive events. Corrected the issue by swapping the RAM out for the 2666 MHz. ... show more
