Problem with GeIL 2GB PC6400 800MHz on DS4

[Harbz]

Hello,

I built my system a few days ago using a DS4, the Geil ram and a intel 6400 core 2 duo.

when running everything at stock, I am getting errors in memtest when running at the memories rated speed, at SPD, and even at 533mhz.

I am using the default + 0.3v to make it 2.1V.

Is the ram faulty?

thanks.
