I'm looking to upgrade my HP dx7510 MT desktop PC. I bought Kingston DDR3 4GB RAM PC-1600. I remove the old RAM and replace it with new one. But the RAM is not detected. I brought the RAM back to where I bought it, but it seems to work just fine when the technician there tested it on his PC. What could be the problem?

The product specifications page doesn't say much about the supported memory configurations for your pc, but third-party sites indicate that it accepts DDR3-1066 or DDR3-1333 only. DDR3-1600 is not supported. Secondly, the pc will take a maximum 2GB stick in each of its 4 slots. If you bought a single 4GB stick, it won't take it. Get a set of 2x 2GB modules if you want a total of 4GB memory. If you're adding an extra 4GB to the existing memory, try to find an exact match for the existing module(s) or at least match the speed of the existing memory. For example, if you currently have a 2GB DDR3-1066 module installed, install a 2x 2GB of DDR3-1066 as well.

Did the store refund your money? Did you buy it based on their recommendation? If so, then for sure, they should have researched compatibility first and they would have found the same information Stansestans did - that your board supports up to 2GB sticks.

[SOLVED] Computer unbelievably slow, will more RAM fix it?
My computer is extremely, extremely slow, for example opening the Windows Calculator can take 30 or more seconds, so just imagine how slow doing actual work is. When I built the computer I intentionally built it with too little RAM to save money to upgrade it later which I still have never done....
