Hey everybody,

I've been reading and reading and I'm just not sure what to think, so if anyone has time to answer some silly questions, that'd be awesome.

I have 4 2gb OCZ Obsidian rated at 1600, but they don't run it at stock...

So, I have edited the timings in the bios to 9-9-9-24 (recommended) and voltage to 1.65 (also recommended)
I have set the freq. to 1600

As far as I know, thats all I needed to do? Anyways CPU-z still reports a 800Mhz freq... not sure if i'm not counting a multiplier or something, or I'm completely missing something. There was no difference in boot, no stability issues, just a bit confused.

Thank you

X3 720BE 2.8 @ X4 3.0 / Crossfire 5770's OC'd / 8GB OCZ Obsidian / Intel X25-M & Caviar Blue / Asus M4A79XTD-EVO / EA750W PSU

Everything is ok. Don't worry.
DDR means Double Data rate. The interface uses double pumping (transferring data on both the rising and falling edges of the clock signal), so that value (800) is multiplied by 2. Therefore 800Mhzx2=1600Mhz which is the specificated speed.
