(Note, that the OS will report 4 GB, but will not be able to use all of it.) This limit will disappear when the addressing space is expanded from 32 bits to 64 bits. The result is that you’ll end up with only 3.2-3.4 GB of memory, depending on the computer you’re using. What they don’t mention, is that addressing of other hardware is also done in the same address space. The Intel 945 chipset only supports 32-bit addressing, which does allow for up to “4 GB of memory”. (As in the next two months.)Īnd, before you cry about me not needing so much memory for browsing the web or sending email, I’d like to point out that yes, I do run heavy scientific applications on my computers… Since Apple update their laptops roughly every 6 months, and last update came in October, its rather likely that we’ll see an update fairly soon. If I recall correctly, the memory performance decreases when you go from 2 GB to 3 GB.
I should also mention that this would also let the computer run dual-channel memory, which requires two memory modules in order to work. Since the MacBook Pro is such an expensive computer, at least to me, being able to upgrade the memory beyond 3 GB will extend its usable life. When Santa Rosa comes, it will finally be updated to full 64-bit architecture, which means that I can put 4 GB of memory in the computer. When they introduced the Core 2 Duo line, I was disappointed that it didn’t support 4 GB of memory, but that’s to be expected when the motherboard chipset was made for 32-bit CPUs. No, the MacBook line that is available now is quite good. So you feel that the Macbook line that is available today is crap?Īre you replying to me? If so, did you even read what I wrote? On the off chance that you’re not the troll i think you are, I’ll answer.
