1Gb SODIMM in 12" PowerBook?

[mstecker]

I'm trying to figure out whether or not (and if not, why not) a 1G SODIMM would work in a 12" PowerBook (bringing the total memory to 1.156G.

I recall that when the 12" came out, the largest PC2100 DDR SODIMM made was 512MB. Now IBM makes a 1G part:

This KB article from Apple:


http://docs.info.apple.com/article.html?artnum=14870

indicates that the maximum memory is 640 (the 128M built in with a 512M SODIMM), but is this a limitation of the memory controller? Or just a practical limitation of what was on the market when that was written? Anyone want to try this out for me?

it will work, its already been confirmed by another company who made them.

It will work, but I think it will only see 1GB, not the 1152 MB or whatever it is. I think the motherboard (or something on it) limits how much RAM the computer will see to 1GB.

Anyone know where I can order one?

Does anyone have a link for someplace that will sell me one of these today? My googling is turning up (shockingly!) a bunch of useless stuff.

Got 700 bucks? That is how much I remember it costing when I read about the 1 GB DIMM.

If I find it, I'll post it though, no matter how much it costs.

It's a lot more than $700, but this site usually has the best deals:

wow... $80 for 512, $1100 for 1 gig. Not exactly getting your money's worth there...

It'll have to come down, but right now that's just crazy. over 50% the cost of a brand new 12" PB for and extra 512 RAM??

Commoditization my friend. I too am eagerly waiting for others to introduce these chips so we can get reasonable prices...

well even if nobody needs it but that meens the 17'' can hoold up to 2 giga of ram ?

Thank you, thank you, thank you. I'm so glad that someone else knows that a GigaByte is 1024 MB.

Actually the 12" and the 17" have a maximum RAM capacity of 4Gb. Will we ever see an affordable 4Gb chip in the next few years? Probably not.
