I just purchased another 2 gigs of memory for my new iMac computer (Corsiar memory). I now have 3 gigs. I noticed that there was a Corsair sticker on the memory stick? My friend told me that I did not need to remove it when I installed the newmemory. Was he correct or should I have taken off the sticker that was on the memory stick before I ionstalled it in my Imac? Are these stickers heat resistant? I read somewhere by removing the stickers it invalidates the warranty. Is Corsair memory good? Also, Apple says in their manual to use a #2 Phillips screwdriver to take off the latch to insert memory. Well I used one and it seems as though it stripped the screw now!!
