Re: [PLUG] lshw - wrong?!


It's seeing the third and fourth banks, which are not in use. Banks != slots. Also, the 3584 bit width on bank #1 is clearly bogus.

Nvidia got back out of the chipset business for very good reason. Their boards always had errata lists as long as my arm, they were almost as bad as Via.

Had an interesting problem recently. Have a Zotac GeForce 9300 (MCP7a) motherboard with 4GB memory. I'm going to upgrade to 8GBs. (lshw w current config below). 

The output makes it look like there are 4 banks with two populated. But the board only has 2 banks. I've never paid attention to the many types of memory through time short of getting what my board needed. I feel like I'm outta the know on this... what is this?
