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 "Every memory chip paid a price in terms of latency."

AMD needs more things like this if they want to retake the ground they lost to Core 2 Duo - sure this is a server technology but the point is the same. I'm an AMD fan because they stimulate competition in the processor market but even I had to opt for Intel this time around. I'd really like to see AMD make a fighting come back but, other than this, I haven't seen any evidence that it will happen.

Don't have much time to read the article right now, but how much more memory could it allow? We already have 128GB of memory one one of our servers.... think that was the max windows enterprise would let us use or it was the max our server board held, I forget, it was a while ago we bought that...

If you read the entire article you'd know Intel are also working on this thing themselves ;). AMD better get this out, nice an polished before Intel do imo.
