Hello! Welcome. Is it showing that speed in the bios or in some 3 party program like cpu-z?
Do you have any other memory sticks installed best the 4gb Kingston.

i'm seeing it on the bios,i have ×2 2gb ddr3 kingston

 

[naruto5538]

Oh i see that's different then. . What's the model number of the memory? Should be on the stick itself.

Also look and see what the FSB is set to

 

[omaralzoubi200]

kvr1333d3n9/2g

 

[omaralzoubi200]

what is FSB?

 

[Tradesman1]

Front Side Bus i.e. with 775 mobos to run 1333 DRAM the whole rig (FSB) needs to be at 1333 which can OC earlier CPUs that are based on a 800 FSB

ok,but what about my first quastion?

 

[Tradesman1]

Guessing your FSB is at it's default of prob 800, the DRAM is at the default 400 (this is DDR (DOUBLE data rate) so default (400) x 2 = effective or 800

 

[omaralzoubi200]

in cpu z i shows 400 mhz too

 

[Tradesman1]

Yes, that is true freq which explained before- so it's effectively running at 800 since it's DDR
