Memory not running at his speed

[arn1404]

hello everybody,

i have a problem.
it seems my memmory is not running at its speed.
my setup is following:
- asus rampage iV extreme
- intel core i7 3930k
and corsair dominator gt CMT16GX3M4X2133C9

is it compatibilie problems?
or could it be because my psu is 6 years old. its a zalman zm850-hp?

What is it running at?

U need to OC the RAM. It Runs at the native speed 1600MHz, right?

Or higher, if used with XMP enabled.

thanks for the advice.
i will try it and tell you how it goes

ok, i tryed and the result is:
- i enabled XMP
- i oc my ram to 1866 mhz, because at 2133 it doesn't want to boot up.
now in windows the program cpu-z tells me the ram is running at 933.3 mhz.

what am i doing wrong?

No need to worry the real clock speed is half of it
mean 1600 is 800mhz

933.3 = 1866

Try to increase the voltage by 0.1V @ 2133

there's not much difference at oc memory
