Is it feasible th change the first DIMM (not shown as user upgradeable) on a hemisphere-base flat panel iMac?

If so, does anyone have a link to instructions?

Yes it is, but you have to disassemble a lot of iMac to get to it. MacAddict had a how-to a few years back; maybe it's on their web site...


I have an iMac FP and also have a copy of the take-apart manual. The iMac FP comes apart like a layer cake (or perhaps a bombe). The DIMM in question is in the bottom layer, just above the user accessible RAM and Airport card slots. The chip is a standard chip, sitting in a run-of-the-mill RAM slot. There are two precautions when getting inside this part of the machine. Quoting from the manual as follows:

"Warning: Whenever the bottom housing is opened for service, you must do two things: (1) You must clean the original thermal film from the surface joining the thermal interface layer and reapply thermal paste to the thermal pipe. (2) You must tighten the four torx screws on the bottom housing to a minimum of 17 in.-lbs. ...snip... Failure to follow either of these steps could cause the computer to overhead and damage internal components."

Warnings aside, it is not complicated. If you would like a copy of the take-apart send me a note off list. It is a 4.1 MB PDF file.
