I am in the process of putting together a computer which has a DG43RK motherboard. I have installed 2-4GB Geil Value Plus DDR3 DIMMS in every configuration possible (including installing each one as a single channel configuration) and every time I get three beeps and no post. From my research online it looks like this memory is non-ecc although it doesn't actually state that on the memory packaging or the sellers description. I have no idea if the memory is SPD, but from Intel's literature it looks like I should reach the post if the memory is non-SPD. Is 4GB per stick too much memory for this board? Is this memory incompatible for some other reason? I saw a previous post which involved bent pins on the processor causing memory errors. I have removed the processor and looked at it in a mirror. It doesn't appear that any of the pins are bent.
It looks like the board shipped with the original firmware, and a more recent firmware allows 2Gb (lowercase as in bit) memory. I'm not sure what that means. Each of my memory sticks are 4 GB (uppercase as in Byte). Will updating the firmware fix my problem?
