Why is 4gb ram the the ceiling?

8gb wouldnt make a difference when the video card would be a limiting factor on performance. 4gb is more than enough for normal people, which is what the 13 inch is made for.
im betting the 17" pro they are gonna release will support upwards of 10gb.
I believe it has to do with the chipset. I've heard of people putting more than 4gb but it usually causes the machine to shutdown because of overheating.
trust me, if the 17" was going to be same they would of released it at the same time.
they will give major bumps to specs and give it fw to appease the "pro" starbucks people.
4gb isnt the limit, you can go buy 8gb and put it in if you want.. the system will run pathetically slow though.
MBP's can run up to 6gb of RAM perfectly, with no slow down in performance.
It is with an adapter. If I had a $1 to bet I would bet 17" will be exactly like the 15" that was just introduced. The 17" may have a bit faster processor and higher resolution but thats about it.
they may offer a bigger capacity of HD's, might be extra ports (if they dont **** it up like they have done with the new MBP's), POSSIBLY a blu-ray reader/writer of some sort (12.5mm is a lot cheaper and stuff), i highly doubt they will though.
*sigh*
It's more complicated that a definative yes/no it doesn't work...

With all 64 bit operating systems, it will always be a chipset or technology limitation, where the technology limitation is how many GBs they can fit on a DIMM. (The OS could limit it as well, but theoretically they should support 2^64 Bytes of RAM).
In this case, the current chipset limitation is 4 GB (for new nvidia chipsets). It is limited specifically by the chipset because the RAM ceiling directly affects the number of address lines the bus needs.

Santa Rosa supports 8 GB of RAM. At the time it was hard enough to even get a hold of 2 x 2 GB for a reasonable price.
I suspect that the nVidia chipset does support 8 GB as well but the price of a DDR3 SODIMM is what's preventing Apple from offering the option.
8 GB should work just fine on a Santa Rosa MacBook. It's thought the the 8 GB of RAM in addition to mapping the video RAM as well on a MacBook Pro is causing problems and limiting them to 6 GB.

The Macbooks/Pros do support 8Gb of ram. The only problem is finding two 4Gb DDR3 sticks for a good price, or even finding a place that sells them.
Apple's website mentions 4gb as the ceiling, but that may well be the paper limit mentioned in another thread.
Someone just needs to buy this: http://www.crucial.com/store/partspecs.aspx?imodule=ct2kit51264bc1067
and we're on our way to testing the true limit.
that isnt the limit, the limit is 8gb of RAM, this has been tested by a user on this forum. there are no problems addressing the 8gb but the system doesnt run very fast, 6gb seems to be the limit for the best performance ratio.
sure you do, what if you run 3 VM's? + PS + editing in HD, that would require a ton of RAM.
This is exactly my point - if you're doing this sort of thing - certainly "editing in HD" then you will not be buying a MacBook in the first place.
