Why is the asus 7870 using low memory

i have a ASUS 7870 V2,,,, 1100mhz core clock,,,,,,1250mhz memory clock. 2 gb ddr 2

i have done various tests with gpu-z....msi afterburner,,,asus gpu tweak.

they all show similar results or exactly the same for all the various areas ...ie

temp
fan speed.
gpu usage
core clock
memory clock
vddc.
memory usage.
but the memory usage is very low,,,on any stress test,,,,,
it gets no higher than 200---300 mbs,,and still uses a couple of mbs of the mobo memory.

asus crosshair v formula.
amd fx 8150 3.6 ghz 8 core.
8 gbs corsair vengence 1866 mhz.
antec high current gamer 900 w psu.
asus hd 7870 direct cu ll top v2.

  1. it will only use as much memory as needed by the game your running, some games i have sip around 300 - 400 MB while bf3 on ultra sucks 1.5GB

    That's completely normal. Stress tests don't necessarily use a lot of ram and anything running on your graphics card is going to require the CPU and motherboard RAM to feed it. All sounds normal - enjoy your system.
