Without knowing what type of ram you are using and assuming you have it set to auto yes it could be correct. If your system is crashing it could be due to anything. You can always do the standard troubleshooting steps such as running your system with a single stick of memory or running memtest. You could use whocrashed to review your memory dumps and see if that provides you any information as well as reviewing your computers event logs. Eitherway posting a screen shot of your memory timings and asking if it's right isn't going to be enough to help you.
