Hi, all. I am looking to upgrade my PC in the next couple months (e.g., new video card, PSU, RAM). I am, however, a noob/newb/whatever with computer stuff. I read in some places you can switch dual-channel RAM to single-channel, but I don't know what that is. I'm a casual gamer and I would like to upgrade my HP Pavilion a810n from 512 MB PC3200 RAM to 1.5 GB. http://www.newegg.com/Product/Product.asp?Item=N82E16820141423 I'm looking at this RAM. I have no idea what brand the memory in my system is now. Will this dual-channel RAM work with a different brand of RAM and what's in this PC of mine right now? This is sort of embarrassing not knowing much about computers and asking questions like this. I hope I came to the right place, though. Thanks in advance. I'll be checking back, of course lol.
