Hi,

I am building a system and my motherboard book isn't 100% clear on this.

Is this RAM type: Corsair Twinx1024-3200XLPT 1GB XMS DDR 400

compatible with a ASUS A8S-X motherboard. DDR 400 works but I want to be sure before I buy the RAM. Thanks,

Matt

All the major RAM makers have wizards for you to plug in your motherboard information and find compatible RAM. Corsair is no exception. See Corsair's here.
