Since I bought my A4000 there has been issues with the chip-ram slot. One of the holders where broken when I got it and I sometimes had to unseat and reseat the ram-block to get it to boot.
Last night - while fiddeleing around once more :-) - the last holder broke off.
I have found a solution that holds the block in place (earplugs that rests between my Mediator logicboard and the block - old school computing!!). It works but I do not know for how long.
I think I know the ansver to this question: Can I use another slot for the chip RAM?
So basicly the only solutions is sending the board to reapir to get the holder replaced?
