Hey I'm trying to help out a friend by upgrading his RAM in his HP Compaq 6710b. I was just wondering if someone knew which RAM to buy. The only concerns I have is that the RAM be compatible with the laptop. Also that RAM would not be bad for the laptop. Let me explain. I purchase a little while ago an Acer Netbook. There wasn't enough RAM in the machine so I went to look for an upgrade. Thankfully I found a DIY vid where the guy explains how to install and cautions users to only use RAM of that size and speed. The reason being is that the system can't handle faster and larger RAMs. Putting one in might cause the system to burn out.
