I have a HP Pavilion 21-a256in AIO Desktop with 4 GB RAM. I would like to upgrade the memory to 8GB. What is correct RAM type that I should buy for this upgrade. DIMM or SODIMM. Can someone help me with full details to look for the correct memory?
Is it 4gb PC3-12800 (DDR3-1600) SO-DIMM for desktop
4gb PC3-12800 (DDR3-1600) DIMM for desktop
Please provide the exact details that would help me buy in HP or any other online vendor like Amazon or EBay.
