I am curious if anyone has any insight into my problem. My new ThinkPad W510 arrived today. Though it is a nice machine, I am very annoyed that Lenovo stopped selling machines with Linux preinstalled. But that is a complaint for another day.
I ordered the minimum RAM from Lenovo, and then ordered 16 GB (4 x 4 GB sodimms) off of NewEgg. I replaced the memory, and rebooted the machine. Facts: * The BIOS only reports 8GB of installed memory. * Using "free", Linux appears to only see 7GB of memory--I am guessing the video card has the rest. * Memtest reports only 3GB of memory, but I think this is a known bug. * Memtest reports 4x4GB Dimms installed. It correctly lists the brand and model of each sodimm. * Lenovo advertises this model as supporting 16 GB in 4 sodimms. * I'm using Kubuntu 10.04 x64. * I checked my BIOS version and it appears to be the lastest (1.24). Questions: * How can memtest see the sodimms, but the OS isn't using them? * Do I need to do something for all the RAM to appear? * If one sodimm is bad, will it prevent the other one from being used? (i.e. do they have to be paired?) * Any suggestions on what I should do next?
