Most probably it is due to ram, try resetting your bios settings. And trying again.
Set the ram frequencies and timing as per the card specifies.
What is you power supply wattage? If it is low that can also cause problem.
Also see that all connections are properly plugged in.
Well just ran a memtest and got a bunch of errors so im going to have to rma my ram. I have a 630w psu and all my connections are plugged in
