You're an angel.. I hate to reveal just how ignorant I am...So, here I am trying to figure out my RAM.. I think the answer is.....(drum roll)..that I have a 1GB DDR SDRAM...Is that sounding right? You had made a reference to 512 KB..that, I've got as well listed in my L2 Cache (per CPU). You know, this feels slightly humiliating as I am pretty savvy with my Mac..but, yet..am completely at a loss with this. Thank you...thank you..
