Hi Jim:
Thanks,John, but I had no idea 256 of ram would not be enough to run a
word processing program.
Yeah. Lots of people think a word-processing program is "simple" because
what we do with it is simple. However, under the hood, Microsoft Word is
the most complex program you have, and the job it is doing for you makes it
the most system-intensive application you have! Word is far more complex
than most publishing programs
The other thing that's worth mentioning is that your operating system is
using MOST of the first 256 MB of memory
What many people miss is that
Apples are Reduced Instruction Set Computers. Very simplistically, the idea
was that by reducing the complexity of the instructions a CPU had to decode,
it could decode and execute them faster. While that is true, it is also
true that if you use only short words in a sentence you need twice as many
words to express the same meaning. Same in computers: a RISC program is
typically twice the size of the alternative. So while Windows XP will sort
of work on 256 MB of memory, Mac OS X needs 512 to do the same job, because
the programs are twice the size in memory. Apple was trying to hit a price
point, and I think they did the wrong thing.
Reviews of the Imac I read suggested I Tunes
and video editing would be a problem.
Yeah, they would have been. Those two are CPU-intensive applications that
also need a fair bit of memory to store whatever it is they are working on.
In that case, while the application is simple, it works very hard and needs
memory to store what it is making. In Word's case, what it is making is
relatively small, but the application itself is large and complex. To get
Word to respond quickly, it needs to be held "resident" in memory. OS X
will do that automatically for you if it has the spare memory to do so. If
every time you want Word to do something the computer has to go find the
relevant bit of it on disk and load it into memory, you will live in wait
city.
Since those were not priorities
for me, I went with what came standard. I will consider upgrading but
1 gig costs $600! A bit much on a machine that was already pretty
expensive. Would upgrading to 512 make a difference? Does the 512
get added to the 256 or does it simply replace it? Sorry but I've not
upgraded memory before.
Neither had Beth until a little while ago
The instructions Apple
provides are very clear, and while the operation is terrifying the first
time you do it, it really is as simple as clicking a card into a slot.
I would follow Beth's suggestion and order a 512 MB stick of memory from the
shop Daiya suggested. That's what I did. Nobody buys memory from Apple
unless they get it installed at the factory: Apple charges at least twice
what the stuff is worth!!
You have one stick of 256 in there. The 512 you order will add to that,
giving you 768. That will be ample unless you start running Virtual PC. Or
hammering the video editor
And it will make a huge difference to your
performance.
Just be really careful what you order: check and double-check that you are
ordering the exactly correct component. Most websites are very good about
ensuring that you get the correct part. Apples are not as forgiving about
memory as PCs. A PC will use almost anything that fits: with an Apple, you
will get crashes (or the damn thing will simply refuse to boot!!) if you put
the wrong flavour in
The first time you put the memory in if you have not done this before, it is
likely that you will not get it to click into place properly. If that
happens, when you restart, the computer will not show that it has any
increase in memory. Simply switch off, pull it out, and put it in again
carefully. Not getting the memory to connect properly on the first attempt
is quite common (it happened to me, twice). It's very scary, but it does
not usually mean that you have zapped the new memory: it's usually a plain
common-or-garden old-fashioned loose connection
Hope this helps
