Gigabyte 780g and Gskill ram. Compatable?

[underbyte18]

I own a Gigabyte 780g that is DDR2 1066 standard. I have tried two ddr2 800 brands but both do not work. The Gskill I bought to go with it is the F2-6400CL5D-4GBPQ.

Does anyone know if this is why I wont get beep codes when I boot?

What are the rest of your specs? How many ram sticks do you have? You could just try one stick at a time to see if it will post that way. Also, are the brands of ram you bought on the supported vendors list?
