Put yourself in his position- what would be fair? Clearly he has bad ram. Maybe it was damaged in shipping (doubtful), maybe he damaged it (possible), maybe it was defective when you prepared and packaged it (possible). I havent used Techtool Pro for memory testing, but I have used memtest, and it basically needs to run overnight to rule out memory defects.
true .
i can accept all of those scenarios cutterman .
however , from my perspective - the RAM was more than likely inadvertently damaged by the buyer (due to reasons already discussed).
In which case , i'm finding it very hard to accept that i should have to foot the bill for someone else's negligence !
there is also the possibility that he is using mixed blends of RAM ... he already stated that he'd tried many different "configurations" .
In order to ascertain what RAM he was already using , i asked him right at the start . He didn't reply to that question .
I also asked him to describe his installation process , which he never did .
I'd be interested to learn if anyone has ever come across Kernel Panics etc due to mixing and matching of RAM ?
