System consists of asus M4A785TD-M EVO , PHENOM 2 945 , COOLMASTER 700W SILENT AND 6GB ON SAMSUNG DDR3 1333 OEM (FROM A CANABALIZED SYSTEM). System powers-up , but does not post. According to the beep codes , it is a failiure of 64k of memory. Now , i have 4 memory sticks (2/2gb , 2/1bg) and after trying each one individualy , none of them allow the system to post. Now , i can see one stick going bad but all four? Anyway, if this is not uncommon please let me know before i go and replace all of the ram. Any other advise would be appreciated.
first : clear the cmos
second : try again each of them, make sure to hear the 2 "clip" sound from the dimm so the dimm is correctly inserted
run memtest+ on each of them.
IF NO POST
I was able to post with a faulty ram tho so it might be your motherboard. RMA your motherboard.
check if your 4 pin / 8 pin cpu cable is correctly inserted. Also check the 20+4 pins. Some motherboards looks like they have a 4 pin but there is a cap on the other 4, make sure to remove it and connect the 8 pins cable.
