Hello

I need some more memory for a G3(PowerPC 750) 400Mhz Powerbook.
At the moment it has 2 sticks summing to 192meg, the system
preferences
say

SODIMM0/J2 64MB SDRAM PC100-322S
SODIMM1/J1 128MB SDRAM PC100-322S

I can't work out from google if there are 3 slots or 2 slots in these
machines, how many are there?

I am running Mac OS 10.3, will increasing the memory increase the
performance of the machine noticeably?


Cheers

Tony

According to the specifications on Apple's web site, there are 2.

You didn't specify which machine you have, so I can't give the link for
your machine.

www.crucial.com, an online memory vendor with very easily-accessible
information on a wide-range of models, lists two G3-400 Powerbooks...
one they refer to as a 66 MHz FrontSide bus.

It has two slots, taking a max of 384 MB of ram.... they sell a 256 MB
piece for US$109.99, a 128 MB for US$45.99, and a 64 MB for US $31.99...

What they refer to as the G3 400 MHz Firewire/Pismo model also has two
slots, but can use up to 512 MB pieces, for a max of 1024 MB... the 512
MB pieces sell (at crucial.com) for US$136.99.

So check whether your Powerbook has firewire onboard or not... if not,
perhaps replace the 64 MB with a 256 MB piece for a total of 384 MB. If
it does have firewire, I would replace the 64 MB with a 512 MB, for a
total of 640 MB.

Either way, you should see good improvement in performance.

Crucial.com is not the cheapest source of RAM online, but they sell
quality RAM, delivery quickly, and offer good support. They're worth
considering as your source.
