It was slow, like ready-to-throw-out-the-window slow. Choice was replace or try an upgrade. After finding out the type of RAM I would need, I started searching around and came across this little gem. To be blunt, my expectations of such inexpensive memory were not very high. I pictured receiving two green sticks in a box with no protection or proper electronic packaging that would not fit, not work, or anything else you can imagine. I decided I would give it shot and ordered it. The package arrived very fast and looked exactly like they do in the picture. So, I installed them along with the original 512MB sticks the computer came with, giving it a total of 3GB, almost the max for 32-bit systems. They clicked and locked into place perfectly and had no noticeable wiggle in the memory slots. I turned the computer on, half expecting to see it not recognize the full 3GB (2GB set from A-Tech and original 1GB) and to my pleasant surprise, it showed all 3GB. Additionally, and the whole reason I purchased the upgrade, the computer was faster, not a little faster, but a lot faster. It has been about two months now and the memory is still working great, with the computer being used over 4 hours a day. I admit that I can be skeptical, yet I took a chance on this memory, and it has surpassed all of my expectations...it blew them away. I did not give it 5 stars because it is the fastest and the top-rated one out there, I gave it 5 stars because it was far above and beyond what I was expecting for the cost. If you have a computer that you want to get a bit more time out of without spending a ton for new memory, I would recommend giving this one a shot. Review: No problems! Great replacement for faulty memory. - Worked fine. Have been running for several months with no issues. ## Features - Memory RAM Compatible for select DDR2 capable Desktop, PC Computers + Easy to install at home, no expertise required - Maximize your system's performance, boost loading speeds, and multitask with ease - Backed by A-Tech's Lifetime Warranty + Friendly tech support team available to help before and after your purchase - 2GB RAM Kit ( 2 x 1GB Modules ) | DDR2 DIMM 240-Pin - Speeds up to 800MHz, PC2-6400 - NON-ECC Unbuffered ( UDIMM ) | 1Rx8 or 2Rx8 - Single or Dual Rank | JEDEC DDR2 standard 1.8V ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C537BQ6 | | Additional Features | Lightweight | | Best Sellers Rank | #989 in Computer Memory | | Brand | A-Tech | | Column Address Strobe Latency | 6 | | Compatible Devices | Desktop | | Computer Memory Size | 2 GB | | Customer Reviews | 4.6 out of 5 stars 334 Reviews | | Data Transfer Rate | 6400 megabytes_per_second | | Form Factor | DIMM | | Manufacturer | A-Tech Components | | Memory Form Factor | UDIMM | | Memory Generation | DDR2 | | Memory Speed | 800 MHz | | Mfr Part Number | FBA_CT2KIT12864AA800 | | Model Name | FBA_CT2KIT12864AA800 | | Model Number | FBA_CT2KIT12864AA800 | | Number of Items | 2 | | Number of Pins | 240 | | RAM Memory Technology | DDR2 | | RAM Size | 2 GB | | Special Feature | Lightweight | | Unit Count | 2 Count | | Voltage | 1.8 volts | | Warranty Description | Limited Lifetime Warranty Covering Defects In Materials And Workmanship | ## Product Details - **Brand:** A-Tech - **Compatible Devices:** Desktop - **Computer Memory Size:** 2 GB - **Memory Speed:** 667 MHz - **RAM Memory Technology:** DDR2 ## Images ![A-Tech 2GB (2x1GB) DDR2 800MHz UDIMM PC2-6400 CL6 1.8V DIMM Non-ECC Unbuffered Desktop RAM Memory Modules - Image 1](https://m.media-amazon.com/images/I/818ihMpjLBL.jpg) ![A-Tech 2GB (2x1GB) DDR2 800MHz UDIMM PC2-6400 CL6 1.8V DIMM Non-ECC Unbuffered Desktop RAM Memory Modules - Image 2](https://m.media-amazon.com/images/I/71ndKnSZITL.jpg) ![A-Tech 2GB (2x1GB) DDR2 800MHz UDIMM PC2-6400 CL6 1.8V DIMM Non-ECC Unbuffered Desktop RAM Memory Modules - Image 3](https://m.media-amazon.com/images/I/713-fT+6JaL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Greatly Exceeded Expectations *by N***E on February 1, 2014* One of the computers in the house is an older Vista system that had 1GB of RAM.

Great replacement for faulty memory. *by C***Y on October 20, 2025* Worked fine. Have been running for several months with no issues. ### ⭐⭐⭐⭐⭐ Nice affordable 2GB upgrade to a 1GB system. *by G***D on December 27, 2013* My 1GB system is now a 3GB system without breaking the bank. The purchase was made during the Thanksgiving holiday so I received it a little late, understandable so no biggie. I was running a Dell Optiplex 745 with a Core 2 Duo 1.86GHz and 1GB RAM, it's now a Core 2 Duo 2.4GHz and 3GB RAM. These Fit right in and were recognized immediately with no hassles. I installed these at the same time I installed a faster CPU and everything is running much faster! I give these a 5 star rating now based on a few weeks use, but the real test is long term performance. ## Frequently Bought Together - A-Tech 2GB (2x1GB) DDR2 667MHz UDIMM PC2-5300 CL5 1.8V DIMM Non-ECC Unbuffered Desktop RAM Memory Modules - Kingston 480GB A400 SATA 3 2.5" Internal SSD SA400S37/480G - HDD Replacement for Increase Performance - Crucial BX500 1TB 3D NAND SATA 2.5-Inch Internal SSD, up to 540MB/s - CT1000BX500SSD1, Solid State Drive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1784428-a-tech-2gb-2x1gb-ddr2-800mhz-udimm-pc2-6400-cl6](https://www.desertcart.us/products/1784428-a-tech-2gb-2x1gb-ddr2-800mhz-udimm-pc2-6400-cl6) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-20*
