man reading that thread scared me, makes me feel like all this instability people may see could stem from yet another source...anyway i just hope someone can find some sort of fix for the problem, whatever it may be

it happens only with high vdimm or not?

 

how can I know if my vtt is bad too?

 

thanks

 

not sure about a lower vdimm, perhaps you could check?

I don't have a multimeter :(

 

Sorry :(

 

you really should look into getting one. they come in handy for a lot of things, not just on computers....$30 at radio shack ;)

This may well explain some of the odd results I've been getting from day one on my memory OC's. May explain why Vdimm was bouncing around so much and I had to bump 3.3 rail up a bit more to get it stable at 3.1-3.2 V. D*mn I wish I had an O'scope.

wrong .. has nothing to do with this

Actually the first o-scope shots given there were with tccd ram at about 3.0v vdimm

 

It appears the occt o-scope shots are also at 3.0v vdimm and I assume the same tccd mem as first oscope shots

 

Having a dmm is a good thing to do, but you will not see this issue/problem with a dmm, you would have to have a very nice o-scope like emc2 obviously has access to (in the olden days that was a $10,000.00 dollar scope, not sure what they cost now days)
