Sounds like a process for an electric frying pan and peanut oil.
Wear gloves and a face shield ( unless your really stupid ).
Use a chip puller tool or make something up with stiff wire
( like coat hanger, a little bending and filing ).
After they cool, wash then with dish soap.

its worth.
That depends on the RAM chips, how rare they are, and how much you need
them.

peanut oil.
I strongly diagree. Using oil (even olive, as peanut and vegtable oil is
banned in my kitchen) is asking for a messy burn.
Use what the "pros" use: solder and a solder pot.

There is an oil called Fusing Oil specifically designed for fusing
circuit boards (heating the tin-lead plating to a point where it alloys
to solder) that could be used. Another route is to use a heat gun on the
back side and use the "slam-bang" method of removing the chips. Having
used all three methods, I prefer the solder pot approach, but it is not
always available. My second choice is the slam-bang method :).

I think I have a bottl of that stuff, but I never tried it.

Oh yes, I have done this as well.
Whatever method is used, it is very wise to preheat the chips before they
are pulled. Not so fast, but not so light either - the idea is to reduce
the thermal shock when the poor things are exposed to the real heat.
