I have a Asus p5q Pro mobo which i have been running with 2x2 bg DD2 -800. Today i got my order from New Egg with my new case fans and another 2x2gb of ram The ram is the same as what is already in the computer..
Problems- I add the two new sticks for a total of 8g and the pc turns on, but nothing on my monitor. So, i thought to myself maybe one is bad. I took all the ram out and started the computer with just one stick in till i tested all 4. Everything worked fine.
So, I put my two old sticks in and 1 new stick, The computer starts to boot and when it gets to the screen saying "loading windows" it just reboots and keeps going.
Here are some things i have tried.
I played around with the timings to a 5-5-5-15-6-55-6 that i found in other fourms, That didn't change anything. I also set NB to 1.30 V and keep increasing a bit and decreasing, to no luck.
I really hope someone can help me with this I've looked everywhere..

Your exact kit is not on that QVL. It's rare but that alone is reason enough for it not to work. You tried everything I can think of. It's actually common for a voltage bump to be necessary when populating all 4 DIMMs in a DDR2 system. That did not fix it though. You might try 2.2v just for the hell of it.
