I have inspiring 15 n 5030 and just installed 8gb ram. The chips work fine and the specs say I have 8gb but it is still running at 3gb speed.. Core and bus speed the same I changed the size through windows settings and it increased the total and available virtual memory by 4gb each, and increased the available physical..the chips are cl9 but it is still at 6 docks…what do I need to do? Also the chips are 4gb a piece DDR3 1333 dual channel SODIMM

For clarification, 8gb RAM is memory, and allows for more programs to run at the same time without slowing down the system. If the system still only detects 3gb RAM, you probably are running a 32-bit version of Windows. You need to install a 64-bit version of Windows to use most or all of the 8gb RAM. For a speed boost, I suggest changing the hard drive either to a Seagate SSHD or a full SSD.
