wbmw,

what are some of those "radical" things that will change the pace of memory that has been constant over the last 3 decades?

I don't see anything really radical, but I don't think it will take anything radical to get to 4 GB.

The next stop for the memory makers is apparently going to be 1 Gbit chip. I have not heard much about companies going to 512 Gb (so I guess they are skipping it). This means that the same way a power user can but today 1 GB for a dual channel mobo, which consists of 2 DIMMs, each DIMM with 16 256 Gb chips.

You don't have to go out of your way to get this. The price now is less than $200 for this configuration.

When the 256 Mb chip is replaced with 1 Gb, these 2 DIMMs become 4 GB of memory. At that point, it becomes inefficient to have an OS that doesn't let you use 1/2 or 1/4 of it in your app.

When will the 1 Gbit chips become mainstream? I don't know. Has anybody seen industry predictions / roadmaps?

Samsung will have them next hear. Initially, they will of course be expensive, but my guess is that they will become a standard within 2 years.

Server guys will of course always be dealing with 2x the amount of memory, since the registered DIMMs can have 32/36 chips. And, to make things even easier, servers typically have more DIMM slots.
