I used this for a second channel on an HP-400 Pavilion Slim line series computer with an AMD processor. The low end computer was fine with it's single channel 4gb DIMM but I wanted a bit more "oomph" out of it so I was very careful to match what was existing, all of the numbers are important, DIMM, 240 pin, PC-3-12800 and 16000 MT/s, 4GB single DR3. Finding all of that information took maybe 20 minutes to open the case and visually inspect the memory that was already installed. Note that the published references, for this HP model at least do NOT accurately reflect what's in the computer so you need to check what's actually in there and read the info off of the part label. Important: Make sure to unplug the power cord first!!!
Once you have the information order the new part(s), as always Amazon does a great job with delivery. The Dimm chip installs in seconds, just align the copper contact edge, press firmly until it locks into place, put the cover back on and re-start your computer.
If you've done your research properly your computer will take a minute to reconfigure itself and on your next re-start you should see a terrific speed improvement. If the computer doesn't start, or if it starts beeping or starts doing strange stuff turn it off, remove the new chip and try to figure out what you did wrong.
The key here is to get a RAM memory chip that matches what your system is configured for in terms of speed, latency and number of pins. You want to increase the capacity, for example 4GB instead of 2GB, or in my case two channels of 4GB each instead of one channel of 4GB. In and of itself the increase in size will noticeably increase your speed without having to get involved in attempting to change the "clocking" of the system.
If you don't understand what I'm talking about in the previous paragraph stick with simply matching the specs of the existing memory. If you do understand what I'm talking about please see if you can explain it better than I can, I'm trying to make it simple and understandable but I doubt that I'm succeeding. I hope the techies out there will agree that it doesn't make much sense to try to overclock a low end system. Adding additional memory is the best as well as the simplest low cost/cost effective upgrade you can do.
Long story short: the Crucial 4GB Single DDR3 1600MT/s PC3-12800 UDIMM 240 pin took longer to get out of the packaging than to install. It perfectly matched my system and has performed flawlessly. Highly Recommended
