iMac G4 memory issue

[makleod]

I recently got an iMac G4 (http://www.everymac.com/systems/apple/imac/stats/imac_700_fp.html) and I am attempting to upgrade the memory. The specs show that it takes 1 512 mb PC 133 SDRAM SODIMM and 1 512 mb PC 133 SDRAM DIMM. The computer originally came with 256 mb (2x128). I upgraded the SODIMM to 512 mb - no problem. However, I have gone through 2 RAM sticks (http://www.amazon.com/512MB-SDRAM-1...7MY0/ref=sr_1_1?ie=UTF8&qid=1302143645&sr=8-1) and (http://www.amazon.com/Generic-512-M...8IKV/ref=sr_1_2?ie=UTF8&qid=1302143669&sr=8-2), but they WILL NOT POST or show up in "About my Mac" or the system profiler. I am really confused as to what's going on because it recognizes the original 128 mb DIMM no problem. Is the RAM I am using incompatible? It doesn't seem to be as it's PC133 SDRAM DIMMs. Looking for any other iMac G4 owners who have some advice...

Golden rule: do not buy no name RAM. Most of it won't work.
Well known brands like Crucial/Micron, Corsair, Kingston, Hynix, Samsung, Infineon etc. will work. RAM must be low density (ask seller before buying in case of any doubts).

I bought an iMac G4 last Sept and this is the memory stick I used to upgrade it to 1GB

Obviously, it's not in stock but from the part number you can get the specs and see what else will match it. It's worked fine for almost 8 months now.

Yea, I figured I was going to get burned with cheap RAM, but had to try just in case it worked. Thanks! I'll order the WINTEC RAM and it should work.
