Description

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.

  • From 4gb To 16gb And My PC Is Peppier, A Procedure I should Have Done A Long Time Ago!
Size: 16GB Kit (2 x 8GB) Style: DDR3L
For a Dell Optiplex 790 Intel i3, Windows 10 64bit, upgrading from 2gb x 2, or 4gb to 16gb, with 8gb x 2. I grounded myself carefully by touching the chassis. Popped out the 2 bars of 2gb each by carefully pushing on both sides lever and inserted the new 8gb x 2 bars in their respective slots, the same slots as the old DDRs we are replacing. Make sure they are well seated and also pushing up and in, the 2 levers at both ends. Restarted the PC and everything booted up without problem, went into Bios and confirmed 16gb is recognized. Everything seems faster. I needed this upgrade in order to run Quickbooks Desktop Plus 2024 which is 64bit and requires at least 8gb. So far day 2, Quickbooks runs faster and also for everything else like Explorer for file transfer and Chrome for Internet run peppier. Over all, I am very pleased with this upgrade and should have done it a long time ago considering the straight forward Ram swap procedure and the immediate speed gain. ... show more

  • Great Performance Upgrade!
Size: 16GB Kit (2 x 8GB) Style: DDR3L
I recently upgraded my desktop with the A-Tech 16GB (2x8GB) DDR3/DDR3L RAM, and I couldn't be happier with the results! Installation was a breeze, and the modules fit perfectly in my system. The 1600MHz speed is impressive, and I immediately noticed improved performance during multitasking and gaming. Whether I’m running multiple applications or playing graphics-intensive games, this RAM handles everything smoothly. I appreciate the affordability of this RAM compared to other brands without sacrificing quality. The fact that it's non-ECC and operates at a low voltage of 1.35V makes it energy efficient, too. Overall, I highly recommend the A-Tech RAM for anyone looking to enhance their desktop’s performance without breaking the bank. It’s a solid investment! ... show more

  • Works fine

Easy to install and improved internet speed with the addition of SSD. This computer isn’t used for gaming so no answers there.

  • Easy to install - much better performance on computer
Size: 16GB Kit (2 x 8GB) Style: DDR3L
This was for an old Dell Optiplex 7010 which had 4GB of memory and a hard drive. This computer always had the memory at 90+% full and the hard drive was almost always at 100% utilization (not full, but just always reading and writing to the disk). It would take 5 minutes just to start computer and bring up a browser. After upgrading the memory to 16GB and adding a $20 SSD the computer is SO MUCH NICER to use. Startup now takes less than a minute and I can have multiple windows open and the memory usage is only at 35% or so and disk utilization is usually less than 10%. I used to hate this computer but now it is a pleasure to use. So for about $60 the computer is working much better than when it was new. ... show more
