So, no matter what I do, I can't get a reading of 800mhz on this ram.
my setup is:
Wolfdale 3500 3.16ghz dual core OC to 3.8ghz (9.5X400mhz) 1600FSB
Kingston 2x1gb DDR2 6400 800Mhz Ram
PNY 8800GT
AsusTek P5KPL-CM (overclocker's budget-board)
(you can set the clocks to 667, 800, 1000, or 1100 on your ram)
When I'm reading cpu-z readouts it does say FSB
RAM = 1:1, I built my computer but I'm not so educated on clocks, ratios, and such.
Any help would be appreciated, I've treid going into the bois and changing the clock speed to 800 but it always just reads back at 400. I may just go out and buy 4gb's of some Crosiar 1066 Ram, but i want to make sure i can fix this problem so i don't end up running my new memory at 400 as well! (Also i'd like to know what i should set it to when i get it, 1000 or 1100?)
~Thanks

Multiply that 400 by 2 and you have 800. Core clock for DDR2 800 is 400, and that's likely what your bios is displaying. Setting your ram speed to 800 would effectively clock it to 1600, which just won't work.
My core dram clock is 420.6, which makes the effective ram speed 841.2. You're fine.

If your DRAM frequency is at 480 then that means that your ram is actually running at 960Mhz. You should be more than happy at the moment =)
Example :
444.5 x 2 = 889Mhz DDR2
