A-Tech 4GB DDR2 800MHz UDIMM PC2-6400 CL6 2Rx8 1.8V DIMM Non-ECC Unbuffered Desktop RAM Memory Module

Got 8g for my pc, Dell xps 710 and so far it works and been smooth. Unlike the motoeagles ram sticks which work but than failed later on

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.

Worked great on old ASUS motherboard Pentium dual core, with only 2 memory slots, upgraded from 4 to 8 GB. I'm running Windows 10 with no problems at all. I'm a Very Happy Customer!

My present PC had 2GB's of RAM, with it's 4 slots holding 512 MB's of RAM each. My PC will hold up to 8 GB's of RAM, so I decided to give these a try. I took 2 old modules out and replaced them with these, and left the 2 other modules in there so that my total memory would be 5 GB's. My PC started acting up doing it this way, my startup menu's graphics would become distorted in minutes, though the speed of the PC seemed faster at first. A-Tech emailed me and asked if I was pleased with my purchase, and I told them what problems I was having and what I thought would fix it. The only solution they offered was to replace the modules I ordered from them with faster modules from them for the same price, which was a nice offer but one that wasn't needed.The problem turned out to be that my new RAM modules, even though they have the same specs as the older ones (except for memory size, obviously), don't like working with my older RAM modules. I took the last 2 older RAM modules out, and all the distortions went away. Not sure why the A-Tech spokesman wouldn't have known that doing this would have helped, maybe this is just a problem with my specific computer, though I did read online at several different sites that this is not an uncommon problem when adding RAM. Still, I do appreciate the correspondence from A-Tech, and their memory modules are working fine. I may order another pair, since the price is right and could help even more. Shipping was on time and in good shape.

One of the computers in the house is an older Vista system that had 1GB of RAM. 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.
