"2 channel" DDR SDRAM?

[Guest]

Just a thought, dunno if the discussion's been up before.

Anyway, why is'nt there (or is there?) a DDR chipset yet, that use a wider memory bus? ONE of the reasons the P4 have such a great memory performance is that the I850 chipset use dual channel and so requires two memory modules to be installed. I saw that Tyan (I think) have made a chipset like this for SDRAM, which really boosted the memory performance, so I don't see why it couldn't be done with the DDR SDRAM also?

Well, well. It was just a thought..

nivida is comeing out with a laptop mother board that use dual chanel and get 4.2 gigabytes per second but it is going to show up with the palominos in laptops first

Yeah Nvidia Crush for Palomino Laptop's will have Dual Channel DDR, and I have heard that VIA may make a Server version of their Northwood P4 DDR Chipset (Called P4X266) that would have Dual Channel DDR. I am not sure what Dual Channel DDR would do for Palomino/Thunderbird but with the P4 it could be a Rambus Killer because it would provide more bandwidth than current RDRAM on 850 and with lower latency. The issue with Dual Channel DDR, is that it costs a lot of money to implement. Why isn't the same thing being said about 850 and Dual RDRAM? because with RDRAM they have to make 2 16-bit wide buses, with DDR/SDRAM they would have to make 2 64-bit wide buses thus increasing manufacturing costs significatly, so we will have to see. Oh and I don't think it's Tyan you're thinking of I think you're thinking of Serverworks' Server Chipset for Pentium III's that has Dual Channel SDRAM.

Serverworks' Grand Champion HE Chipset has 4-way interleaved PC1600 (for a total of 6.4 GB/S)
5 GB/S I/O throughput
6 independent PCI-X segments (64bit/100Mhz)
2/4-way XEON
