Deciphering the words and numbers on my memory module

Posted on 2014-08-30
Medium Priority
Last Modified: 2014-09-10
My memory strip has the following written on a label:
2Rx8  PC3 12800U 11-12-B1 SK Hynix

1.  What do those words/symbols mean?
2.  When I purchase additional memory, which of those symbols should I type into the "memory purchase search box"?
3.  Is there a better quality memory than SK Hynix? For instance Corsair? Samsung?  Is there an independent web site that tests memory specs?

If it works then don't change it.. Corsair and Kingston are known manufacturers.  SK Hynix is not as well known but I've seen Apple computers with this memory, if that gives you any idea.

Usually you would use the motherboard manufactures recommendations.

If your system is running fine, then I would not change the memory. If you want to change memory, you should check the specs on your motherboard or system specs from the manufacturer. Based on that, you use Kingston, Patriot or other name brand ram.

I have see Hynix used on servers, but not desktops or laptops.

<>>  When I purchase additional memory, which of those symbols should I type into the "memory purchase search box"?  <<  you don't use them - better use the memory selector tool for your PC; it suggests what you need
the best - of course is to go to the PC manaufacturer site, and check on the supported ram they propose

>>   Is there a better quality memory than SK Hynix? For instance Corsair? Samsung?  Is there an independent web site that tests memory specs?   <<  i don't know about better quality, since most come with a lifelong warranty
as for testing ram (not specs) - i use the memtest86+ which you find on the UBCD, or at www.memtest.org
