Tried installing 4 sticks of mem with same latency 3 will work but cant get the 4th post error long beeps downloaded updates for vista and mobo still no. Played around with different mem voltages still no. Any ideas I know lots of people are having the same problem according to other forums Heres hoping
^^^you should be able to. try running memtest86 on each stick individually.you may have a bad module or maybe your mb just doesnt like all four dimms populated.you can also try swapping the sticks to dif dimms to see if their is in fact a bad module.
All the sticks are in good order tried different configs with them so i know they all work. As im a bit of a noob to o/cing where it says mem running at 800mhz do i just type in 667 to change it
That should do it. It's also a more or less known fact that Nvidia chipsets 650/680 series are not really happy with 4GB of RAM on some mothoerboards (this is approved by Nvidia). If downclocking does not help try bumping the voltage a bit.
