The problem im having is that ive just bought 8GB G.Skill RIPJAWS DDR3-1333GHz and put it in my PC, but when bringing up anything it says that there is 8GB there but its only using 4GB, it says that there is only 4GB in the BIOS to.

Please help me.

Thank you

This is what my Resorce Moniter says also, notice the 4.1GB reserved for hardware?

Can I ask a silly question?

Are you sure you installed 64 bit? I only asked because once I grabbed the wrong disk.

Duh.....

Power the system off, pull out your ram, plug them back in. I had to do this exact same thing on a laptop the other day for the same reason. Worked like a charm - they looked seated properly but the motherboard didn't agree!

This is copied directly from my DXDIAG and was in the first post.

Will give this a shot.

I read somewhere about reinstalling Windows but deleting the partition, just did that and hasnt worked.

After extensive testing with both sockets of Ram,
checking the CPU connector for bend pins and the ram its self.
The conclusion is that the 2nd ram slot is damaged.
Does anyone know how i check the warranty of the motherboard?
