    has any one had a similar problem? ive got a power mac g5 dual 1.8ghz.. i just bought some kingston memory .two sticks of 512 ddr3200/400 desktop. I put the memory in and the machine recognizes the upgrade and boots real quick but as soon as i run a program it crashes..when i take out the new memory it runs as before but if i take out my pre existing memory and run the sticks of 512 it wont boot. I know it is a memory issue but does anyone know why?????.... the specs are correct and i am running them in pairs wtf? thanks everyone

    I don't know a ton about it but I just ran into a problem where my computer only recognized half of the chip I installed. The consensous from other people on this site was that even though the specs were right there are other configuration issues involved in some chips. I had to send my chip back and am waiting for a new one to see if that solves the problem. So in short it seems that even if the specs appear to match the chip might not be right.
