    I have a Lenovo Ideapad z575 with an AMD A-Series APU, and also a discrete video card which I can run in Crossfire if I so choose.

    I have been having problems with it randomly restarting without any error in even viewer, no blue screen, nothing. It seems to have begun doing this when I tried upgrading the memory by swapping the 2gb stick for a 4gb (8gb total), and it does not seem to be overheating. It will do it playing youtube videos, gaming, and also just sitting idle in chrome.

    I have noticed that according to CPU-Z my memory is currently running with very low timings compared to their specifications, and I don't know why. I have tried switching slots, switching sticks, removing sticks, etc, and it does not change this. I have no option in the BIOS to change memory timings, and am wondering if it has something to to with the integrated video processor on the APU.

    Any help would be great!

    Also, it should be noted that I don't have the 2gb stick anymore to try putting it back to stock.

    Actually it looks like using Slot #1 allows it to run at the correct timings. Why would Slot #2 force both banks to use the wrong (faster) timings?

    And now for some reason it looks like I can add the second slot and have correct timings... how strange. It is still restarting when playing flash video.
