Input: I purchased this for my HP Elitebook 8540W laptop to increase the memory from 8G to 12G. There are two additional memory slots on the back of the laptop. Takes seconds to open and I found one slot already had a 4G 204-pin RAM, so I purchased this one that has the matching speed of the one I have. It arrived within two days, and I plugged it in. Worked perfectly!
Output:
Works great with my HP Elitebook 8540W
