Howdy, has any individual commissioned 8GB of RAM on a T400 (model 2768 CTO with most cutting edge BIOS)? Since so what mark / detail works? I've tried instating 2 x 4GB Corsair DDR3 PC3-8500. It didn't work. I would have done well to get my motherboard reinstated under my warranty. The information on the Lenovo post is opposing concerning what the max RAM underpinned is, either 4GB or 8GB. I totally require something greater than 4GB to run virtual machines, so in the event that its feasible I'd love to expertise.
