In my Mac mini system profiler it says DDR SDRAM (PC3200U-30330). On the iBook specs page it states SDRAM DDR 333.

Dumb but quick: will it work?

Thanks :)

No it will not work, You mini uses standard size DDR memory sticks, the laptop uses much smaller "SoDIMM" DDR sticks. They wont work with each other.

At the risk of piling on ---nope. completely different.

But ther's an opportunity to explain the numbers you are seeing.

PC3200U means PC3200 (DDR 400 MHz) RAM, Unbuffered
-30330 means the latency timings, these are often abbreviated to CAS Latency 3 or CL3. Has nowt to do with the MHz speed of the RAM.

PC3200/DDR400MHz and PC2700/DDR333 MHz describe ONLY the speed of the RAM module, not the packaging. So a PC2700 module could be a 184 pin DIMM, a 200 pin SODIMM, or a MicroDIMM -- and these are all mutually incompatible of course.

Thanks for this... I had actually always wondered what those numbers were all about :)
