I want to max out the ram on my M90Z. Processor is G6960 i7. windows 7-pro 64bit. Factory said 4gb when it was new, I have 8gb in it now. Would like to go to 16 or 32, But wanted to know it would work before I invested in a new kit. I always try to use matched pairs in all my equipment. Thanks for any help or suggestions...D...
