Review: No problems! Great replacement for faulty memory. - Worked fine. Have been running for several months with no issues.
Review: Highly compatible DDR2 RAM Modules, can handle both 800 MHz PC-6400 and 667 MHz PC-5300 excellent value! - This is an excellent product, I got two 4GB kits (4 modules), and all four worked just great, fully compatible with both Intel based computers where they were installed, I feel these memory modules are an excellent value, and revived a pair of 8+ year old computers, one of the computers is an Asrock G31M-GS based system, the other an Elitegroup 945GCT-M/1333 v3.0 with max RAM specs of 4GB (2 GB per slot) DDR2 667 MHz PC-5300, but I took a chance with these RAMs and they adjusted perfectly from 800 MHz down to 667 MHz (not all RAM modules can do this), in other words these modules can handle both 800 MHz PC-6400 and 667 MHz PC-5300. I would definitely like to try A-Tech's other RAM modules like DDR3 in the near future. It must be noted that (at least the ones I got), these RAMs can not handle the 533 MHz PC-4200 standard, this was not a problem for me, but if your motherboard/system is of an older type that can only accept this standard, then these modules won't work for you. Bottom line is that if your system/motherboard can handle 240-pin DIMM (Desktop PC), non ECC, DDR2, PC-6400 (800 MHz) or PC-5300 (667 MHz) RAM, then I would say there is a 99% chance these modules will be compatible with it. Tip, if for example you plan to get 4 GB of RAM,, get a kit (2 modules of 2 GB each), vs getting a single 4 GB stick, when you get a kit (two identical modules) you can benefit from dual channel, that way you can get a full 800 MHz speed vs just 400 MHz from a PC-6400 DDR2 when you use a single or an odd number of RAM sticks.
