4GB dimms anytime soon?

Hi all,

just wanted to know if anybody knows about new or planned so-dimm with more than 2GBytes which we could stick in our future T6x? I have not found anything. I think the next intel platform will support more than 4Gbytes.

Regards,

Wolfgang

actually, the current intel santa rosa chipset should support 8GB total.   we just need the modules to be released.

keep in mind that 32-bit apps can only address a maximum of 2GB each even with a 64-bit OS.   until we see more 64-bit native apps, more memory won't have much benefit.

But I have read that the chipset in the T61's is maxed at 2 gb per slot.

Santa Rosa Platform (Centrino Pro) supports 8 GB

• Supports 8GB of Memory
The Mobile Intel® 965 Express Chipset Family supports a main memory size up to 8GB.

How expensive are the 4 GB RAMS?

4GB modules haven't been released yet, otherwise i'd own two of them. :D

According to this update, the MOBILE Intel 965 can only handle up to 4gb of DDR2 (different from the desktop specs):

But who knows, I hope you are right!

that datasheet also says "256-Mb, 512-Mb, and 1-Gb memory technologies supported" and we all know that 2GB modules work just fine.   it reminds me of the A3x-series when intel claimed a maximum of 1GB on its chipset but users were able to install 1.5~2GB and all of it could be addressed.

besides, if we consider the topic of memory hoisting, the PM965/GM965 would have to support more than 4GB for all 4GB to be addressed by a 36- or 64-bit OS since that last 1GB gets hoisted above the 4GB mark.   given that, i have no doubt that 8GB is supported and would be absolutely shocked if it wasn't. ;)
