G3 imac and more Ram
I have an imac 600MHz with 192 MB ram. When I first got this machine it was running OS 9 and I added a 512 stick of ram. Everything worked fine, but when I upgraded to OS 10.3.9 I had problems with unexplained crashes and freezes. Took out the 512 (Legacy) stick and stuck with the old 64 and 128 (both apple) sticks. Everything was fine. I put it down to a flakey stick, as it was a used one bought off this forum.
I decided last week to upgrade the ram, so I purchased a PC100 SDram 512 size (that is what I have in it now) over the internet. It is a Kingston (KVR100X64C2/512). It arrived today and I put it in the computer with the 128 stick. Fired it up and the memory shows up under the apple in "About this Mac". Seems to work fine. Within 10 minutes my computer completely freezes up...totally. So, I unplug it, and remove the 128 stick thinking there might be a conflict between the two types. I fired it up again and within 10 minutes the same thing....complete freeze up. I was even running "repair permissions" thinking there might be a problem somewhere and it still froze up. This is very similar to my old 512 stick problems. Out with the 512 and now only put in the 128 as the 64 got damaged from all the in and out processes.
I phoned Kingston. They will replace the 512 with another stick the same but also mentioned they reccommend a slightly differnt model # KTA-IMAC100/512 They looked at the specs they are the same. I would have to pay an additional $28 to get the newer one.
Has anyone else had this problem? Am I using inferior ram sticks? Maybe I should be using only Apple memory? I've got to do something now because OS X is sure slow on 128 MB of ram. Thanks.
