VGA_LED when increasing RAM speed

[Josh Brumpton]

When I increase the RAM speed to 1866 like this ram is meant to be, the computer wont restart and the VGA_LED comes on. I have to use the MEMOK button to get it working. I think its set at auto now, whats wrong?

Thanks

In bios there was just a drop down list of speeds mhz. I just put it on 1866 and restarted

The cpu and mobo seems fine...

the thing to do :

stick just one ram and set it to 1866 see if it boot?

if it boot try run extended memtest for about 2-3 cycles... if it show no error try the other stick...

if both are fine, then need to check each slot if there a damaged slot (by try insert 1 ram and boot, try another slot,...)

slot combination 1-3, and 2-4 see if it work...

the last thing if it still don't work/no failure detected I would try update the mobo BIOS..
(it risky, but it also bring some fix & improvement)

This a long process in testing........... and if it don't work there a problems else where...
