Buffalo Announces DDR3 Memory Modules

Japanese Buffalo Ltd. anounced that it will ship its first DDR3 memory modules in Japan by the end of the month. The company will offer a kit of 512MB memory modules (2x 512MB), a single 1GB module as well as a 2GB set (2x1GB). The DDR3 memory standard is considered as the successor of the DDR2 SDRAM. It promises power consumption reduction of 40% compared to current DDR2 modules, allowing lower operating voltages (1.5V, compared to 1.8V in DDR2 modules). Buffalo's new modules run at 1,066MHz((PC3-8500) and maintain the 240-pin DIMM interface of DDR2. Intel has preliminarily announced that they expect to be able to offer support for DDR3 in mid 2007 with a version of their upcoming P35 Bearlake chipset. AMD's roadmap indicates their own adoption of DDR3 to come in 2008.

Kickin!

To everyone, think these would eventually be compatible to an LGA775 mobo with PCI-e slots?

I think this means you need a new chipset/mobo (northbridge/southbridge or something).
So yeah not compatable with todays boards I believe.

I think they may be compatible now. Then again, perhaps only after a voltmod or bios hack. AMD was supposed to start the migration to DDR3 before Intel...wonder what happened here.

I was thinking that too but then I saw the words "same interface design", then wheels started churning. Updated bios, old motherboard .... "??"

DDR3 specification originally called for a different pin layout, its interesting they have somehow managed to keep to 240pins, certainly makes you wonder. I would hazard a guess at they found a way to maintain signal integrity without moving to a new PCB design.

OK... it runs at 1066mhz and uses less power than the dd2.

Right now I am running 1066mhz (OE settings) DDR2 ram. So is this going to have any benifits other than lower voltage consumption?

These are only the first DDR3 models, like the first DDR2 models were DDR2-533, these are DDR3-1066. I can see DDR3-1333 DDR3-1666 etc etc etc...

I know AMD's solution is the following:

AM3 chipsets use a new motherboard/chipset.
AM2 motherboards can take an AM3 CPU, but still need DDR2 ram.

Intel i can only assume, will in fact need new chipsets - intel always do, for hardware upgrades.
