WOULD BUY AGIAN

Bought this 2 stick of ram for a new computer I'm building.They work great out of the box .Ive had it for about 3 mounths with no lacking of speed.would buy agian.

1 gb to 3 gb and 3 gb to 4

I have a compaq with 1 gb 2:(1/2 gb, I add one of these 2 gb and 1 gb from a HP pavillion that had 3 gb, and put the other 2 gb on the pavillion, both computer are super fast can't ask for a better deal, I save over $400.00 from the factory price for the upgraded cp, and can be install in less than 5 minutes

Excellent!

I wanted to put more memory on my Dell eMachine. I had 2x512mb memory cards installed. My computer is kind of old. So I only have
2 memory slots as opposed to the newer computers that have 4 slots.
So I took out one 512mb card and installed the 1024mb card. Now I have more memory, instantly. I wasn't sure if I had to restart my computer in order for it to take effect but I did anyway. I have not had any problems with it. I installed it 2 days ago. I would order another one for my son's computer because it works well and I got it for at a bargain, $20. You can't go wrong with that.

Works well in HP

We use this in some of our DC model business workstation/desktop PC's. It works well, and most importantly for us beyond working, it is very streamlined and doesn't have large heatsink fins. In those DC model HP's there isn't much clearance sometimes between the memory and the power supply, or CD ROM mount area, etc.

Worked well, easy install, good value overall. And as others have said, they aren't interchangeable and often not mixable if you're using other older memory so do your research first if you aren't sure.

Solid memory

Put 2 of these kits in my Optiplex 745 and 755, they run great for 8GB in each. Nice for VMware too.
