Yongxinsheng DDR3 16GB Kit (8GBx2) Desktop RAM 1600MHz PC3-12800 UDIMM Non-ECC Unbuffered 1.5V 2Rx8 Dual Rank 240 Pin CL11 PC Computer Memory Upgrade Module (Blue)

Can't go wrong for the price. Worked fine, no issues and look quite good.

Well it works, and its stable with my old pc, cant complain much.

UPDATE: after 3 months roughly still working well no slow down! Benchmarks show its mid to low high end range and these sticks show as hyinx when picked up by various bench mark software which i beleive is mentioned on their product page, most importantly its still stable, I now have 32 gbs of this installed in a Z200.For the price and fact its not a known or major brand/Manufacturer I wasn't expecting much, but installed this in an old HP workstation im upgrading to give it some more power, Bios picked it up and initialized with no issues, shows up in the system, had it for a week and no loss of function no over heating and seems to work as good as a stick of low end Patriot or Crucial Ram. I would say sometimes its worth taking a risk, some of these lesser known brands are as good as the main ones, they all started somewhere Build quality is also as good as Vengeance shielded ram. If it didn't work was just gonna send it back. I will be buying the black ones now to make sure i have the same ram in the system.

Does the trick to keep an elderly computer ahead of the game. It's always good to have as much RAM as possible. Stuck these in to get my desktop to 32Gb and now it's noticeably quicker.I tend to leave my computer on for extended lengths of time - it's not green but I like to get back to my work with my windows just where I left them. But as time goes by, your computer uses more and more of your resources. With the way that I work, I often don't notice the little signs until it's too late - and the computer freezes.With 32Gb, that particular point in time where it freezes (and I wished I'd noticed sooner) is pushed off to a further point in time. I'm still not that green but I now often can get to a point in my work where I can stop and reboot.
