To be honest, I don't think you can do that. Most newer boards will be setup for Dual Channel which requires matched pairs of RAM to work properly.

I might be wrong (and I'm sure someone will correct me if I am wrong)..

Dual channel RAM does require essentially identical sticks of RAM to work, though you can run non-identical RAM sticks so long as they're not in the dual channel setup.

However, many motherboards and chipsets just don't like mixing sizes of RAM at all and you may well continue to get problems from this.

Best use RAM sticks of the same size. If possible use the same spec too, if you want dual channel to work, which is recommended.

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

Notifications don't work, I only found your response by coming back to hunt up some threads, if you want, give me your email address so we can keep in touch easier!

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
