I recently bought gskill ripjaws x 4gb ddr3 1333mhz ram I already had kingston 2gb 1333mhz. I installed ONLY my new ram stick and my pc keeps restarting at staring windows logo after that i installed only the kingston ram than pc is starting fine in bios both the rams are shown. Is my mobo not supporting my ram? I previously brought a corsair vengeance 1600mhz ram and i got the same issue i thought as my mobo (intel dh55pj) only supports 1333mhz ram it the corsair didnt work but gskill is also giving the same error althought its a 1333mhz ram but kingston is working fine.please help. Thank you in advance.
