i have ram set at 150mhz, after checking it shows its actually at 1361mhz when i bitcoin mine.
So my question to you is how exactly do i lower my ram to 150mhz? what utility? what flags? Suggesting an action is good, but I need to know how to lower my memory mhz more. This card can hit 5.5ghz to 6ghz memory.

You'll need to close the program and reopen it after changing the memory clock to the lowest in order to lower it further.
I run all of my 7000 series cards at 300MHz and get little to no change in hash rate. If you want to further increase your Mh/s, try CGMiner and the following settings:
"intensity" : "7",
"vectors" : "1",
"worksize" : "256",
"kernel" : "diablo",
yes, i remember I used to do this with some problematic 5830's.. (well, I'd switch between one and another if they werent synchronized & it'd then allow me to lower the memory lower)
but with my MSI 7850 and 7870, the lowest it'll go is 600 in afterburner.. i can quit and reload and it's still 600. ulps is disabled, 'extend official overclocking limits' is checked, powerplay is disabled, config file is changed

UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 2
and i've tried trixx, barelyclocked, gputweak, ... everything but RBE basically
i know it's possible, since it comes with 2 performance levels, and the 1st performance level is 150 memory 300 core
it's all a bit puzzling
anyway, the 7850, i can run at 1100-600 and it still doesnt go above 55oC
the 7870 is problematic
