M2N68-AM SE2 does not boot with 4gig of ram

Did you chech the asus site to see if that ram is compatible?
Also can you give the rest of you system specs...graphics card,power supply,etc..

Hi
Have found that there is no problem with RAMS, its just that the CMOS settings do not work properly if they are in AUTO, I just changed the latency to manuel and did 5 5 5 18 which is the max for corsair cmx2 DHX memmories i have got. What u can do is down load CPU-Z ( Just put CPU-Z in google and u will find the down load site on the top of the page) once downloaded, do This:
1. Leave 1 stick of Ram (whatever it is). Then boot the system.
2. Once windows loaded Run CPU-Z and it will show you your system details any way see on top of cpu-z you will see tabs click on SPD. Here you will see your Rams
Timing Table
270mhz 400mhz
4.0 5.0
4 5
4 5
13 18
what u need to do is write it down. Shut the system down and install the second Ram.
3. Restart and go into cmos settings.
4. Select manuel for DRAM Timing.
5. Change the timing to the maximum you got from you CPU-Z timing Table like 5 5 5 18. I am giving u these only as an example so pls check what values u get from CPU-Z for your ram.
6. Save and exit.
Hope this works for you as it has definately working on mine.
