DDR800 Ram at DDR667 Speed

[TJD]

Hi all, I just bought a 4GB kit of Kingstone HyperX RAM (KHX6400D2K2/4G) its rated at 800MHz and CL5. I think it's supposed to run at 2.0volts (don't quote me though), but it's only running at 1.8volts... Consequently (i think) my Gigabyte GA-MA790X-DS4 has down'd the speed of my Ram to 667MHz

Can I just change the settings in BIOS? or have I got some faulty Ram? Any ideas or suggestions are welcome

Thanks heaps.

Edit: P.S. Sorry if this is posted somewhere else, I did have a look around but couldn't find anything..

common prob! no big deal at all. just change it to advertised specs in the bios as you suggested is all!

Thanks for that doubletake. I just changed the settings on my BIOS:
DDR800, 2.0volts 5-5-5-15 1T.
But according to CPU-Z my ram has now jumped from 333Mhz up to only 375.5mhz... shouldn't it be at 400mhz?? CPU-Z also states that my FSB: DRAM ratio is CPU/8, but I can't find anywhere in my BIOS (GA-MA790X-DS4) to change that CPU divider.. does anyone have any ideas???
