Hello,
recently i bought a amd apu- a8 3870k
but i cannot figure out how to set the memory bandwith of the igpu.
i know that the memory bandwidth of igpu depends on the ram frequency.
i have a corsair vengeance 4 gb 1600 mhz ram which i have overclocked to 1866 mhz.
but when i run gpuz instead of showing memory bandwidth 933 mhz it shows 100 mhz only ..cpuz shows ram freq 931 mhz.
can some one help me out?
here are the screen shots

thank you.

looks pretty normal.leave cpu-z open and run a program. what happens ?
morgan the problem is not with cpuz but gpuz ..in case of gpuz ,the memory bandwidth is showing 100 mhz also when any gpu based application is running , instead of 933 mhz, .. though my ram is working at 933 mhz
i want to know why ..
plz help

no the gpu is not in idle state .. i have checked gpuz sensor tab on load state.. here is the screen shot of gpuz sensor tab showing the highest reading of gpu clock , gpu memory clock ..see it is showing 100 mhz on max load..

update your GPU-Z, the latest version is 0.6.6, yours might not yet support the apu correctly

just out of curiosity, what happens when you click on the small questionmark next to the 'bus interface:fusion'? It'll start a small render test, but will it have any effect on anything when you start it?it starts a rendering test ..which cause my gpu to run in max load...but during this test on load.. the usage of memory bandwidth should increase but it is not happening in my case .its showing same 100 mhz...

well that is a bit odd, I also think it should show 933 as the mem clock...though 100MHz is the bus interface clock for the cpu part in the apu, so it's likely showing that instead. I dont think the actuall memory clock can even be 100MHz so it's likely just some reading error in gpu-z...
yes ..it might be the fault of gpuz only...ok thn can u suggest me an alternative software which will show the same details as gpuz?

so finally figured it out ....gpuz was showing wrong readings..
checked & verified it with evga precision & hwinfo both showed memory clock 933 mhz

..thank you every one ..for the help
