Why no SB850 for socket 1366?

post #1 of 7
Thread Starter 
The SB850 is the controller on the Rampage IV(AM3) and it supports 6X Sata 6 ports and supports raids 0/1/5/10...what I wanna know is why haven't they implemented it on the 1366 boards? Is it developed by AMD or is has it not been out since the rampage 1366 boards came out? I just feel like that sucks that if you're gonna have an i7 build you can't have sata 6 with raid unless u buy a special board? am I missing something and jsut haven't done my homework good enough? just curiosity btw.

Would you give your technology to your competitor?

Probably because Intel chose Marvell? I don't know why Intel would use a AMD product on their own chipset? It's like Nvidia putting a NF200 chip on a dual-GPU ATI card.

It's an AMD southbridge.
The technology is not compatible. SB850 uses Alink Express III as its primary interconnect. Intel uses DMI.

The Marvel and NEC SATA 6Gb/s controllers use PCIe and are designed to be add in components.
Once again...

There we go...DMI vs. PCIe. (also important that it's AMD tech.) but that's the major difference maker. thanks for the reply.
