how do you test a mobo memory controller?
i have 3 sticks of supposidly bad ddr ram. a "new" stick of 2700 and one of 2100, and a 3rd of unknown speed which i got out of a huge box of free computer stuff. they all fail the pc check (a self booting diagnostic cd which ive used before when i built computers) ram tester and a few other ram testing progs. specifically the block inversion test is the one which tends to fail. im starting to suspect a bad memory controler on the mobo. the mobo is an ancient msi p4 bored from 2002. its been abused by me for the past several years. im just suspious that all 3 test bad. i dont really have a good stick to test against (and i find buying a new one doesnt mean it will pass).
I can no longer sit back and allow communist infiltration, communist indoctrination, communist subversion, and the international communist conspiracy to sap and impurify all of our precious bodily fluids.

Take the RAM to a different computer and run the test on them, just to be sure. If they pass, then it for sure is the memory controller.


I'm not sure if you can test the mem controller directly.....
"The reason for this is that the original Fortran got so convoluted and extensive (10's of millions of lines of code) that no-one can actually figure out how it works, there's a massive project going on to decode the original Fortran and write a more modern system, but until then, the UK communication network is actually relying heavily on 35 year old Fortran that nobody understands." - Flipside

all my good ram is ddr2. though i did buy a new stick not to long ago which tested bad when i installed it. though it was a really cheap stick and cost less than the shipping to return it woulda been. thats what got me to think it was the memory controler. but it wouldnt be the first time ive seen a spankin' new stick test bad.

all that seems to tell me is at what addresses errors occured, it doesnt seem to tell me if the errors are due to bad ram or bad memory controllers.

Like I said, test the RAM in a different computer, then you will know for sure

run memtest86 in a second computer, and then test it there.
Well what do I do now?  Well Jack, you seem to have an act for blowing things up....

Re: how do you test a mobo memory controller?
like i said all my other computers use ddr2. so i cant just test the ram in another machine. usually thats what id do but i dont have that option.
