AMD claims memory controller breakthrough

AMD has unveiled a new memory controller system which it claims will double the memory capacity on its high-end server and workstation systems.

The G3MX technology will target memory intensive systems such as virtualisation servers and large databases when it becomes available in 2009.

In conventional systems, Ram modules connect directly to a memory controller on the motherboard or are built into the CPU.

In larger systems requiring more memory, a buffer must be used between the memory module and the controller to avoid a decrease in performance. The current choice for this is fully-buffered Ram modules which contain a built-in buffer.

But the problem with fully buffered Ram is that it is expensive and power-hungry, and hampers performance, explained Nathan Brookwood, principal analyst at Insight64.

"Fully buffered Dims were thought to be a big thing, and they turned out not to be," Brookwood told vnunet.com. "Every memory chip paid a price in terms of latency..."

Within 9 months if it's deemed to be valuable, Intel will have their own memory controller advancement much like this one for the Gesher architecture in 2010. It's good to see AMD are pushing it though, despite their worries now they are still making some good progress.

Nice to see AMD still pushing forward.

There's lot of new technology in regards of memory, case in point RDRAM's which never took off, it was just a development.

And doubling the memory capacity? How much memory one will ever need.

I wonder how long it'll be delayed for, if it ever comes out to life.

GG AMD

Now you should make better procs and gfx

HANG IN THERE!!!! *shakes AMD hard*

I was thinking the same..

The THEORETICAL capacity that CPUs today can manage is up in the hundreds of GBs
SO - there must be something more to this.


Perhaps they mean ACTUAL (and not theoretical) the capacity that a server can have (within relative means).

See, CPU's can handle RAM controllers that are linked to buses that can facilitate LOOOADS OF RAM (slots).
BUT, it would be Very expensive to create buses like that.
Thats why, the chip makers state the THEORETICAL capacity of RAM, that their chips can handle - that is, if they sought to use ALL its ... avenues for layman's terms.

So.. unless this improvement means that it will make things simpler for a CPU to control a LOT of ram... much easier (without bulky buses - just PURE slot space)... then - I don't get it

--EDIT--
(I wish the source was given! >.>)

Nobody will ever need more than 640k RAM!

What is the source of the article??? I wonder if this is similiar to the new OCZ memory that makes use of the 11 column address bit support for AM2 boards. Using that on servers alone should be a big performance benefit.

For those interested.... here is a more detailed article about this tech:

http://xbitlabs.com/news/memory/disp...725081324.html

Advanced Micro Devices on Wednesday unveiled a new technology that would enable next-generations of servers to utilize massive memory capacities, something, which will substantially boost server performance. Besides AMD, IDT and Inphi, some of Intel’s FB-DIMM backers, also participate in development.


The new technology currently called Socket G3 Memory Extender (G3MX) is a part of AMD Opteron platform infrastructure due to be unveiled in 2009. The G3MX will support DDR3 SDRAM and will extend the total memory footprint in future AMD Opteron processor-based systems. Even though G3MX is designed in a way similar to Intel’s FB-DIMM, it uses industry-standard memory modules and is a typical memory extender akin to those used by such companies as IBM and HP. It is unclear, however, whether the technology supports mirroring, hot-plug and other capabilities for high-end servers.

As processors become multi-core and support features like virtualization, they need massive amounts of memory to work efficiently. The G3MX is designed to help that.

“AMD’s competitive edge lies with responding to our customers’ requirements now and in the future. As we look ahead to pervasive quad-core and octal-core server computing, AMD is committed to delivering the flexibility and choice our customers desire to successfully deploy virtualization and multi-core environments,” said Randy Allen, corporate vice president, server/workstation division, AMD.

G3MX technology is being developed in collaboration with IDT and Inphi, who are planning to sell G3MX components as part of their power- and cost-effective device portfolios supporting the memory industry.

“True to our collaborative nature, we worked closely with memory technology experts to develop G3MX, as an easy, cost-effective way for customers to attain faster access to memory or additional memory to enable increased performance for complex and emerging applications and environments,” Mr. Allen added.

“AMD and its platform partners have developed an innovative technology that directly addresses the need for efficient and cost-effective memory capability, which is one of the most significant computing requirements of the scientific community,” said Thomas Zacharia, associate laboratory director of Computing and Computational Sciences, Oak Ridge National Laboratory. “The extended platform memory capabilities expected via AMD's upcoming G3MX memory technology should allow the use of bigger memory capacities with industry-standard DIMMs for large workloads to ultimately help to advance scientific research and discovery.”

G3MX is expected to be available in 2009 when AMD introduces its next-generation architecture enhancements.
2009 for next generation architecture enhancements?? What are those?
