It would be unsuitable for this purpose because of it's thickness and because of the residue it tends to leave. I believe there are better options. For what it's worth, at home scotch tape ("invisible" matte kind) worked well enough for me. It didn't get damaged by the slot connector and it didn't leave any residue. YMMV, caveat emptor, beware, use at your own risk, you know the drill.. --Artem On Sat, Nov 6, 2010 at 5:00 PM, wrote: > Artem Belevich wrote: > >> All you need is intentionally make one data bit bad. =A0Put some >> tape on one of the data pads on the DIMM and run memtest ... > > and then spend the next couple of hours cleaning the gunk off of > the DIMM and out of the slot :( >
